Title: Control mechanism for refrigerating systems
IPC: F25B13/00
Filed: 1958-07-15
Abstract: 834,985. Refrigerating; temperatureresponsive actuating elements. RANCO Inc. July 15, 1958 [July 24, 1957], No. 22610/58. Classes 29 and 64(2) [Also in Group XXXVII] In a refrigerating system in which air is circulated over an evaporator by a fan and in which at low air temperatures ice is deposited on the evaporator thus increasing the temperature difference between the air downstream of the evaporator and the evaporator, this increase in the temperature difference initiates defrosting but at air temperatures too high to give rise to ice formation a similar increase in the temperature difference does not result in defrosting. As shown in Fig. 1, a compression system includes outdoor and indoor heat exchangers 11, 16 over which air is forced by fans 21, 22, and a reversing valve 13 actuated by solenoid 23 in circuit with manual switch 27 and thermal control unit 30. The compressor. motor is controlled by a thermal control 24 which energizes the motor when the indoor temperature is either too low or too high. When solenoid 23 is de-energized, the exchangers 11, 16 act as condenser and evaporator to cool the room. When the system is set for heating by closing switch 27, control unit 30 (see Group XXXVII) acts to reverse temporarily the system by de-energizing solenoid 23 for defrosting if the temperature of the air flowing therethrough from the evaporator 11 be less than 40‹F. and if ice should have formed on the evaporator. If, however, the air temperature be above 40‹F. control unit 30 cannot de-energize solenoid 23. Temperature - responsive actuating elements (Fig. 2). A switch contact arm 35 is moved by an actuating arm 44 influenced in one direction by a capsule 54 and in the other direction by a capsule 48. The charge in capsule 48 and its pilot bulb 51 is such that it exists in liquid and vapour phases at temperatures above and below 40‹F. and the charge in capsule 54 is such that it is entirely vaporized above 40‹F. but exists in liquid and vapour phases at temperatures below 40‹F. Capsule 54 is subject to a higher ambient temperature than bulb 51. Thus at temperatures around capsule 54 above 40‹F. any increase in the temperature difference between the capsule systems will maintain arm 44 in raised position, the expansion of vapour alone in capsule 54 being insignificant. At temperatures below 40‹F., however, any increase in the temperature difference results in downward movement of arm 44 to actuate the switch.

Convention date, May 3. Void [Published under Sect. 91 of the Acts]. [Class 100 (iii).] When a line-casting or single-type composing and casting machine is being worked electrically from a distance, an indicator, Fig. 2, at the transmitter ascertains how far the line has proceeded. An additional contact on the transmitting key raises a cam 45, according to the dimension of the character, to close a contact 46 to excite an electromagnet 47, which raises a rack 48 to engage toothed wheel 49. An arm 51 then closes a contact 52 to excite an electromagnet 53, which pulls the rack against a spring 54 until a cam 55 knocks forward the cam 45 to allow the rack to fall and return under spring pressure: A pointer 40, moved by a toothed wheel 56 on the shaft of the wheel 49, is thus advanced a distance depending on the dimension of the character. At the end of each line a signal is sent by a special key, which also closes the circuit of an electromagnet which pulls back the indicating needle to its initial position, Fig. 4 (not shown).

Title: Improvements in or relating to television or like systems
IPC: H04N5/08
Filed: 1934-08-03
Abstract: 439,652. Television. MERDLER, L. R., and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. Aug. 3, 1934, No. 22647. [Classes 40 (iii) and 40 (v)] The synchronizing signals in a television receiver are maintained at a constant level irrespective of intensity control adjustments of the picture signals or of the radio-frequency gain. As shown, the incoming carrier or a carrier derived therefrom by heterodyning, is applied from a circuit 2 to the diode rectifier of a diode-pentode valve 1. The rectified signals in the plate circuit include picture signals and synchronizing signals, and the latter are selected by a rectifying valve 5 so biassed as to respond only thereto. The selected impulses are amplified by a variablemu valve 6, the grid of which is biassed from a resistance 7, 8 connected across the rectifier diode of the valve 1. If the carrier applied to the diode rises in its average strength, greater negative bias is applied to the grid of the valve 6, and the synchronizing impulses are fed to the scanning oscillators at constant strength. The valve 1 may be replaced by a treble-diode pentode two of the diodes serving for full-wave signal rectification, and the other for volume control. When a doublediode pentode is used, these functions may be performed by the diodes separately, or by both jointly. According to the Provisional Specification, the mean strength of the synchronizing signals after their separation may be used as the automatic control.

Filed: 1931-08-11
Abstract: <PICT:0375123/III/1> <PICT:0375123/III/2> <PICT:0375123/III/3> In a method of testing the vacuum in evacuated ampoules containing pharmaceutical and chemical preparations, the ampoules A are first "excited" by passing them between spring electrodes F energized by high frequency supply, and are then passed into the high frequency field between two metal plates or coatings B between which puncture-proof dielectric material G, such as glass, is arranged in layers.  The lower of the dielectric layers G shown may be dispensed with, and the lower metal coating B may be replaced by the ampoule support which is made conducting.  The ampoules are inserted in clips N in a conducting, travelling band L so that their pointed tops P directed downwards are electrostatically shielded by the band and clip.  The resulting colours and structure of the glow in the ampoules in the h.f. field is characteristic of the pressure and contents in the ampoule.  As one ampoule leaves the electrodes of the gap F another one enters it.  The connections comprise a Tesla transformer energized from A.C. supply and connected to a spark gap for the generation of oscillations in the oscillatory circuit comprised by the condensers and transformer the secondary of which is connected to the auxiliary gap F and main discharge condenser in series.  One point of the secondary h.f. circuit is earthed.

Title: Liquid level float and apparatus for testing the same
IPC: G01F23/36
Filed: 1959-07-02
Abstract: 862,150. Indicating liquid levels. AMERICAN DISTRICT TELEGRAPH CO. July 2, 1959 [Oct. 9, 1958], No. 22741/59. Class 123(1) A low level alarm for tanks, &c., in which the correct level must be maintained but which are difficult of access, for example, a roofmounted, fire sprinkler water storage tank for a building, comprises a float 25 mounted on a shaft 26 passing through a flexible seal on the inner face of a housing 15 secured in an aperture in a wall 19 of the tank 10. The shaft 26 carries a contact 27 which closes on a fixed contact 29 when the water stands at its normal level to energize a coil 33 at a remote station. The apparatus incorporates means for testing at the remote station the operability of the float. For this purpose a casing 20 secured to the housing 15 surrounds the float. The casing has a large aperture 30 in its underside for the entry of water and an opening 22 near its top into which is connected a conduit 21 leading from a source 35 of an inert gas such as nitrogen. The conduit has a three-position, solenoid-operated valve 221 therein. When a test of the operability of the float is to be made the valve 221 is moved from its first, i.e. closed, position to its second position by closing a switch at the remote station. In this second position gas enters the casing 20 forcing the water therein downwards. If the apparatus is functioning properly the coil 33 is de-energized when the float reaches the preset "low" level and the alarm is given. On completion of the test the valve 221 is moved momentarily to its third position to vent the casing to atmosphere allowing it to refill with water and then returned to its closed position.

Title: Improvements in thermal time-delay arrangements for electric circuits
IPC: H01H43/30
Filed: 1935-08-13
Abstract: 456,469. Thermal switches ; electromagnetic switches ; retarding action of switches. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, Westminster, and BLOXSIDGE, W. R., 4, Toronto Road, Ilford, Essex. Aug. 13, 1935, No. 22769. [Class 38 (v)] In a time - delay arrangement for an electric circuit, the delay period is determined by the sum of the times taken to heat up and cool the thermal element of a ther mal relay, the oper ation of the relay when it reaches its actuating tempera ture serving to reduce the heating current but not tc break it. The arrangement is such that the total time is independent of variations of voltage, any increase of '' heating '' time due to decrease of voltage for example being balanced by a decrease of " cooling " time due to the smaller heating current flowing during the cooling period. In the arrangement shown in Fig. 1, suitable for use in traffic signalling systems, closure of contacts a<1> completes a circuit to the thermal relay TH. This heats up and eventually a bowed spring th snaps from its upper to its lower position, completing a circuit to a relay B which at b<1> closes a retaining circuit at b<2> opens contacts removing a short circuit from a resistance R<2> and at b<3> prepares the circuit to an alarm AL. The reduced current through the thermal relay due to the resistance R<2 >is insufficient to maintain its temperature and it cools and eventually the bowed spring th snaps back. If before this happens the contacts a<1> have opened owing to a cycle of operations of a master controller having taken place within the prescribed period, relay B is released and the parts assume their original position, but if contacts a<1> are still closed, the movement of the bowed strip th will complete the alarm circuit AL and the alarm will sound till the contacts a<1> open. Fig. 2 shows an arrangement for closing for a predetermined time the high tension and low tension circuits HT and LT to a wireless transmitter. Operation is initiated by momentary closure of switch V. This completes the circuit to the lower coil of a two-coil relay A which operates to close at a<1> and a<2> the circuits HT and LT. The contacts a<1> also complete a retaining circuit for the relay A and a circuit through a bowed strip th to a thermal relay TH. The latter heats up and eventually causes the strip th to snap downwards removing a short circuit from a resistance R<2> which now operates to limit the " heating " current of the relay so that the latter cools down. The removal of the short circuit has also caused current to flow into and charge a condenser C. When at the end of the cooling period, the spring th snaps back, the condenser C discharges through the upper winding of the relay A and the direction of the current is such that it releases the relay A and the contacts a<1>, a<2> open disconnecting the circuits HT, LT. Specification 424,222 is referred to.

Title: Antioxidant concentrates
IPC: C11B5/00
Filed: 1954-08-05
Abstract: An antioxidant concentrate for fats, fatty oils and fatty acids comprises one or more antioxidants and, as a solvent therefor, a reaction product of propylene glycol with mixed glycerides of fatty acids.  The reaction produced is believed to be the result of an ester interchange between the glycol and the mixed glycerides.  The glycerides used are mixtures in any combinations of mono-, di- and tri-glycerides of fats and fatty oils, such as lard, corn oil or cotton seed oil, prepared, for example, as described in Specifications 682,625 and 682,626 [Group IV(b)].  The solvent reaction products are prepared by heating a mixture of propylene glycol and the desired glycerides, with or without a catalyst and preferably in an inert atmosphere such as nitrogen or carbon dioxide. The ratio of the reactants preferably varies between 1 to 3 moles of propylene glycol to 1 mole of the mixed glycerides.  Suitable catalysts comprise sodium hydroxide, orthophosphoric acid and sodium ethoxide.  Propylene glycol may be mixed with the solvent.  The preferred antioxidants are gallic acid esters and alkylated hydroxyphenyl ethers, used separately or together and with or without a synergizing acid or ester.  The preferred gallic acid esters contain as the ester radical an alkyl group of 1 to 12 carbon atoms, and the compounds exemplified include n-propyl gallate and n-lauryl gallate.  The preferred alkylated hydroxyphenyl ethers are tertiary butyl or tertiary amyl hydroxyanisoles or hydroxyphenetoles, and the compounds exemplified include 3-tertiary-butyl-4-hydroxyanisole and 2-tertiary-butyl-4-hydroxyanisole.  The synergizing acid or ester may be citric acid, monoisopropyl citrate, 2-hydroxypropyl citrate, orthophosphoric acid, tartaric acid or ascorbic acid. The fats, fatty oils and fatty acids, which may be stabilized include lard, palm oil, cotton seed oil and stearic acid.

Abstract: 442,596. Synchronous movements. INTERNATIONAL BUSINESS MACHINES CORPORATION, 270, Broadway, New York, U.S.A.-(Assignees of Lemmon, W. S. ; 20, Pine Street, New York, U.S.A.) Aug. 9, 1934, No. 23046. Convention date, Aug. 9, 1933. [Class 40 (iii)] In a telegraph system having transmitting and receiving distributers operating at the same speed and in which the character to be printed is determined by the instant relative to the beginning of the cycle at which a signal impulse is transmitted, a phase control impulse is transmitted at a predetermined point in the sender cycle and the receiving arrangement embodies means responsive to the reception of the control impulse at all positions of the receiving distributer other than that representing phase correspondence to apply one or more steps to the receiving distributer to bring it into phase correspondence with the transmitting distributer. The control impulses are transmitted from contact 2 during each revolution of the arm 9 of a distributer 1 and at the receiver pass to conductor 15 and to a ring 22 if the receiving arm 16 is appreciably out of phase with the arm 9. A magnet 35 energized over the back contact of relay 60 operates a pawl 37 and ratchet 38 to rotate a gear wheel 41, Fig. 2, secured to the housing 43 of a differential gear carrying shafts 49 on which the crown wheels 48 are mounted. The housing and wheel 41 are normally held against movement by spring pressed plungers 46. The rotation of the wheel 41 on each energization of the magnet 35 steps forward the driven shaft 42 carrying the arm 16 relative to the driving shaft 52. In Fig. 2 the ring 22 and segments 23, 24, 25 are on a member 21 engaged by a brush 17 attached to the arm 16. When the arm 16 has been advanced so that it is on the contact 23 at the moment the synchronizing impulse is received the magnet 35 is energized directly. When the arm 16 is on the contact 24 at the instant the control impulse is received, relay 60 operates and a glow discharge lamp 62 indicating that phase correspondence has been reached is illuminated. The armature 33 of relay 60 disconnects the segment 22 from the correcting apparatus and is held open by a dash pot so that signal impulses are prevented from operating the magnet 35 with the consequent stepping of the arm 16. If the receiving arm 16 becomes advanced relative to the arm 9 and engages contact 25 when the control impulse is received, relay 56 operates and through ratchet -and -pawl mechanism 37<a>, 38<a> steps the wheel 40<a> which rotates the wheel 41 so that the shaft 42 is retarded relative to the driving shaft 52.

Title: Improvements relating to apparatus for making cemented pile fabric
IPC: B05C19/00
Filed: 1947-08-20
Abstract: 634,131. Cemented pile fabrics. ALLEN, E. B. Aug. 20, 1947, No. 23101. Convention date, Aug. 20, 1946. [Class 142 (iv)] The invention comprises an improved warp guide for pleating a warp and an improved mechanism for delivering severable separator strips to the warp when making a cemented pile fabric with apparatus of the type described in Specifications 472,707 and 560,290. The warp guide is operated by a rack and pinion driven from one of the two main cam shafts, one at each side of the machine. Movement of the rack in one direction rotates a shaft 126 (not shown) half a revolution. A pin 134, eccentrically mounted on this shaft and connected to the warp guide, causes the top of the guide 119 to move vertically between slides 121, and the lower end of the guide, containing reed frames 109, 110, to swing across the mouth of the passage 37 to form one pleat in the warp. The separator strips B are contained in a magazine and are fed by a bar 156 having a recess 157 to accommodate one strip. In operation, a strip B is fed from the magazine to the bar 156 and lowered to the position shown at the left hand side of Fig. 4. The strip is then transferred to the arm 187 which moves downwards to the position shown in dotted lines, and transfers the strip to a lower arm 216 which swings over to its final position, shown in full lines, and presses the strip on to the warp. Retractable ringers move inwards to hold the strip in position. Faces 191, 218 on the arms 187, 216 have recesses to accommodate one strip B. The suction passages, ending on the faces 191, 218 and on a face 157, are connected to a pump and enable suction to be applied to these faces to retain the strips B. To deliver a strip from a recess, atmospheric pressure is applied to the passages. Shafts 184, 213, on which the transfer arms are mounted, are operated by suitable linkage from cams on the main cam shafts. The bar 156 is moved by a linkage operated by a cam on the shaft 69. The width of the passage 37 is adjustable.
