Filed: 1934-06-12
Abstract: 439,640. Valves. DREWS, J. O., 49, Sydenham Hill, and FIELD, A. J. WUERTZ-, Dominion House, Bartholomew Close, both in London. June 12, 1934, Nos. 17385 and 26544. [Class 135] [See also Group XIII] Refrigerating apparatus working on the reversing absorption system and comprising a generator-absorber 1 and condenser-evaporator 2 connected by a conduit 3 is provided with a ball valve 8 controlling the passage between the two parts, the valve being unseated, when the apparatus is tilted, by a sliding weight 5 so as to initiate an evaporation period at any desired moment. A pivoted weight may be used in place of a sliding weight. The supply of heat to the generator-absorber is stopped when the temperature reaches a desired maximum during the generating period by a trip mechanism comprising a spring-loaded piston 25, Fig. 3 subject to the pressure of a confined body of fluid in a cup 27 in heat conducting connection with the generator absorber. The upper end 24 of the piston rod engages a lever 17 pivoted at 18 and moves the lever against the resistance of a spring 22, which is arranged to effect a snap action of the lever on the arm 15 of a gas cock or electric switch. Alternatively the movement of the lever may cause the discharge of a small quantity of water over the preheating coils of an air-pressure oilvapour burner to extinguish it. Specification 426,105 is referred to.

Title: Improvements in presses for perforating and bending sheet or strip metal
IPC: B21D22/00
Filed: 1944-09-13
Abstract: 578,398. Shearing, punching or bending sheet metal. IRVING, M. M. O. Sept. 13, 1944, Nos. 17528, 19225 and 20393. [Class 83 (iv)] A press for perforating rectangular plates and strips comprises a work table having at least one row of uniformly-spaced holes perpendicular to a reference axis or with a first series of uniformly spaced slots parallel to said axis and with two rows of uniformly spaced holes parallel to said axis or with a second series of uniformly spaced slots perpendicular to said axis, at least two stop members, one of which is adapted to be engaged in any hole of said one row of holes or any slot of said first series of slots and the other of which is adapted to be engaged in any corresponding two holes of said two rows or in any slot of said second series of slots, two series of reference markings on the table for identifying the several locations of the stop members and a head carrying a tool holder which is capable of being reciprocated perpendicularly to said work-table. The press comprises a base 21 and a column 24 with a forwardly extending overarm 25 carrying a tool holder 26 adapted to be vertically reciprocated by means of a hand lever to which is secured an eccentric 33 pivotally linked to the carrier. As shown in Fig. 1, the tool carrier supports a punch 27 co-operating with a stripper 43 and with a hole 41 in a die 40 inset into the work table 20, Fig. 3. When the press is required for the angular bending of strips or plates, the punch is replaced by a bending tool 53, Fig. 4, which co-operates with a bending die 54 inset into a groove 23 in the base. The tool 53 has a forwardly extending nose 55 to permit the double bending of narrow strips (Fig. 5, not shown). Perpendicular to the axis X-X of the die groove 23 are two rows of holes 44, 45, the holes being of #" diameter and “" pitch. Two rows of holes 48, 49 of ¢" pitch extend parallel to the axis X-X. These rows of holes serve to locate stop members 46, 50 respectively each having two depending pins adapted to enter a pair of holes. One side of each stop member, marked N is “" from the line joining the pin centres, whilst the other side is slightly further from the axis so that by turning the member end-to-end, a hole or bend formed in the work would be located in a slightly different position. Thus holes 63-66 punched in two separate sheets 60, 61 which are afterwards bent at right angles may be so positioned that the holes coincide when the sheets are superimposed as shown in Fig. 8'. Fig. 10 shows a modified form of stop member comprising a single locating pin and three locating faces one 74 being nearer the pin than the normal face 75 and one 73 being further from the pin. The differences above or below normal are related to the thickness of the material being worked. If desired, the tool carrier may be provided with a shearing blade for cutting off blanks from a long strip or sheet or with a blanking punch or with a forming or embossing tool. In a modified form the pairs of holes are replaced by slots.

Title: Improvements in spring locks for doors
IPC: E05B65/00
Filed: 1935-06-20
Abstract: 437,256. Spring catches. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. June 20, 1935, No. 17774. Convention date, July 13, 1934. [Class 44] A spring lock for refrigerator doors &c. comprises a catch movably mounted on a carrier displaceable against a spring urging the carrier and catch into locking position, the catch being deflectable either with or relatively to the carrier to permit the door to open under spring action when a detent, normally preventing such deflection, is released to initiate the opening movement of the door. The opening of the door is preferably effected by spring hinges. A carrier 6 guided in a casing 3 by a rear hole 24 and by rollers 25 is pressed outwards by a spring 8 and carries a catch 4 pivoted to the carrier at 7 and normally held rigid therewith by shoulders 10, 11 engaging respectively with a pin 12 and a pivoted hook 16. The device acts as a sliding latch engaging a keeper 5 as the door is closed. The hook 16 is disengaged from the shoulder 11 when a pin 18, housed in the handle of the door, is pressed against a tail-piece 15 on the hook, whereupon the catch 4 can tilt to allow the door to open under the action of its spring hinges. Springs 20 and 17 restore the catch 4 and hook 16 to their original positions when the door is open. Alternatively the carrier may be pivoted and the catch movable longitudinally with respect thereto. Fig. 3 shows a modification in which a catch 31 is pivoted at 33 to a carrier 32 pivoted to the case at 36. A detent 39 prevents tilting of the carrier against a restoring spring 38 until it is moved by a pin 41 connected to a spring button 43 on the front of the door. A spring 34 enables the catch 31 to act as a pivoted latch as the door is closed.

Title: Improvements in or relating to means for controlling the speed of aircraft or the rate of delivery of spray therefrom
IPC: B64D1/18
Filed: 1946-06-13
Abstract: 615,487. Electric control systems. PEST CONTROL, Ltd., and TUDOR, P. W. June 13, 1946, No. 17812. [Class 40 (i)] [Also in Group XXXV] In a system for spraying from an aircraft, particularly a helicopter, the concentration of the spray is maintained at a predetermined level either by controlling the spray valve in accordance with the speed of the aircraft or by maintaining the speed of the aircraft constant. In the system shown in Fig. 1, a chrometric speed indicator which measures the number of revolutions of a shaft over a small period of time is driven by a propeller mounted outside the aircraft and shielded from the downstream of the rotor. This indicator turns a pointer 2 which moves over a resistance 3 mounted on a graduated rotatable dial 4, this charge of resistance being employed in an amplifier 7 to operate the plunger of a solenoid 10 which in turn operates the butterfly valve 14 controlling the fluid feed through a bellcrank lever 11. The dial 4 may be rotated by hand with the resistance 3 which is carried by it to compensate for wind speed and render the spraying rate dependent on ground speed. A knob 6 is provided to alter the ratchet spring tension of the chrometric indicator to adjust the integrating period of the instrument to compensate for gusts. The system as applied to controlling the ground speed of the aircraft is identical except that the bell crank lever operates the throttle valve.

Title: Improvements relating to the recovery of the principal constituents of pyroligneous acid
IPC: C07C51/487
Filed: 1931-06-23
Abstract: The principal volatile liquid organic constituents of pyroligneous acid are separated by adding a phenol or mixture of phenols so as to form molecular compounds with these substances, separating the mixed compounds from the aqueous medium, and applying successively increasing temperatures so as to decompose the molecular compounds successively.  Alternatively the vapour of the pyroligneous acid may be passed through a series of vessels containing a phenol or phenol mixture which are maintained at successively decreasing temperatures such that in each vessel only one molecular compound is formed, these being subsequently heated to higher temperatures to obtain the separate constituents.  In the first method a mixture of m-and pcresols with xylenols is mixed with the pyroligneous acid at 45--50 DEG  C., the water layer being rejected.  The phenolic molecular compounds are then led to a series of columns maintained at 85 DEG , 95 DEG , 100 DEG  and 145 DEG  C. respectively in which acetone methyl alcohol, water, and acetic acid are distilled off separately. In the second process the vapour of pyroligneous acid is passed through a series of vessels containing the same phenolic mixture maintained respectively at 95--100 DEG  C. to absorb acetic acid, 85--90 DEG  C. to absorb methyl alcohol, and from room temperature to 40 DEG  C. to absorb acetone. Each molecular compound is then separately heated as described above.  Specifications 275,158, [Class 32, Distilling, &c.], and 390,185 are referred to.  The Specification as open to inspection under Sect. 91 included also the treatment of aqueous solutions containing organic solvents with one or more organic substances of higher or lower boiling-point capable of forming molecular compounds insoluble in water, which compounds are decanted from the water and fractionally decomposed to obtain the volatile solvents separately.  Volatile solvents mentioned are hydrocarbons alcohols, aldehydes, ketones, acids, and ethers.  This p subject-matter does not appear in the Specification as accepted.

Abstract: 313,920. International General Electric Co., Inc., (Assignees of Allgemeine Electricitõts-Ges.). June 19, 1928, [Convention date]. Void [Published under Seþt. 91 of the Acts]. Rotary converters.-The effects of changes of frequency in alternating current systems I, II upon the operation of coupled synchronous machines 1, 2 interconnecting them are compensated by shifting the exciting field of one of them in correspondence with the change in the frequency difference. This may be effected, when one machine has a stator with a distributed, commutator-fed winding, by rotating the brushes, or, when one machine has a slip-ring fed rotor with distributed winding, by using a threephase excitation at a periodicity corresponding to the frequency difference. Fig. 1 shows an induction motor 4 with stator and rotor connected respectively to the two systems which drives the brushes b<1>, b<2> of one synchronous machine at a speed and in a sense corresponding to the frequency difference between the systems. Fig. 2 shows a similarly connected machine 4 driving a frequency converter 5 which may have no stator. or a threephase exciting machine, supplying the field of the machine 1. The machine 4 may be replaced by two synchronous machines combined with a differential mechanism. A relay controlling a servo motor operating the brushes in the arrangement according to Fig. 2 is also suggested.
