Title: Improvements in endless belt conveyors
Inventor: MASKENS GEOFFREY DAVID
IPC: B65H29/12
Filed: 1960-11-25
Abstract: 923,033. Feeding sheets. SOLARTRON ELECTRONIC GROUP Ltd. Nov. 23, 1961 [Nov. 25, 1960], No. 40672/60. Class 100 (1). [Also in Group XXX] Friction is reduced between an endless conveyer belt and a hollow bar 18 over which the belt passes by blowing air through bores extending over that part of the surface of the bar rubbed against by the belt. Documents are fed from a conveyer (not shown) on to a top main conveyer run 10 and are held down by tapes 13. Unless it is desired to abstract a document, a flap 14 is left in the position shown in full lines and the document slides over the flap to a succeeding conveyer (not shown). When a document is to be abstracted the flap is raised and the document passes over a roller 15 to an underneath run 16. The document is held to the belt around a roller 15 by tapes 17 and is held against the run 16 by a polished metal plate (not shown). After passing around the perforated hollow bar 18 the document is pushed into a throat formed between a slower speed conveyer 28 and tapes 29. Because of its slower speed the conveyer 28 streams the documents before feeding them on to a table 30. The belt completes its circuit by passing around rollers 20, 22 and along transverse run 23 to a second 45 degrees bar around which the belt twists back to a return run 25. The flap 14 can be solenoid operated, e.g. under control of automatic sorting apparatus.

Abstract: 1275945 Transferring articles between endless conveyers AZIONARIA COSTRUZIONI MACCHINE AUTOMAT SpA 14 Aug 1969 [29 Aug 1968] 40778/69 Heading B8A An endless belt 2 conveys articles S from a machine 1 to a feeding section of the belt 2 from which the articles S are delivered by a conveyer belt 4 to a receiving machine (not shown), there being sensing means 19-19 arranged at the feeding section to bring about (when it senses a row of articles S) the positioning of a stop 16 in the path of the conveyer transfer means 17, 18, movably mounted at +he transfer zone, and power means 8 reponsive to the positioning of the stop 16 and arranged to drive the transfer means 17, 18, so as to transfer the articles S from the belt 2 on to the belt 4. In operation, a fluid jack 12 is energized when a row of articles S (sugar lumps) on the conveyer belt 2 obturate a photo-cell beam 19, 19, provided that a previously-transferred row on the belt 4 obturates photo-cells 21, 21, but clears photo-cells 20-20. Members 6, 6a are rocked over by the action of the jack 12 thereby placing a stop bar 16 across the conveyer belt 2, and a member 13 is oscillated so as to operate a switch 15. This operates via a timer (not shown) to actuate a ram 8 connected to a slidable transfer member 18. The latter pushes the row of articles from the belt 2 on to the belt 4. A switch 23 operated by an extension 22 of the member 18 is caused to return the jack 12 to its normal position. The member 13 is oscillated thereby so as to actuate a switch 15a so as to cause retraction of the jack 8.

Title: Improvements in and relating to oil level controllers for oil burners
IPC: F16K31/26
Filed: 1960-11-28
Abstract: 964,890. Valves. BRDR. MICHAELSEN, HEDENSTED, METALSTOBERI OGMASKINFABRIK AS. Nov. 28, 1960 [Nov. 28, 1959; April 22, 1960], No. 40793/60. Heading F2V. A float-operated valve 3 for an oil burner comprises a spring member 31, one end 32 being secured in the cover 18 of a casing and the other end 36 being retained in a set position in the casing by means of a fusible material 35 such as a metal, adapted to melt at a temperature above a certain predetermined value, and thereby release the end 36 so that it strikes the valve spindle or a part connected thereto in order to close the valve. As shown in Fig. 2, a pivoted lever 11, 12 is provided with a roller 15 engaging with a pivoted lever 28 which passes through the end 10 of the valve spindle 4. An extension 26 passes through a slot 21 in the lever 28. In operation, if the level of the oil rises above a certain predetermined value, the float 5 abuts the end of the lever 11 so as to cause the roller to move into a position which permits the lever 28 to move downwardly under the action of a spring 20 and thereby locks the valve 3 in the fully closed position. As a fire precaution, the valve locking mechanism can be operated by means of a spring member 31, 32, Fig. 3, the end 32 abutting a shoulder 33 in the cover 18 of the casing and the end 32 being retained in a set position by means of a pellet of low-melting point material, such as solder. When the temperature rises above a certain value the pellet melts and allows an extension 36 of the end 31 to strike the extension 26 of the lever 12 and thus effects the actuating of the valve mechanism. In a modification, Fig. 1 (not shown), the spring member acts directly on the end 10 of the valve member to maintain it in the closed position.

Abstract: 1,143,169. Pitch frequency detector. INTERNATIONAL BUSINESS MACHINES CORP. 7 Sept., 1967 [13 Sept., 1966], No. 40869/67. Heading H4R. In a circuit for detecting the fundamental frequency of a voice signal when the fundamental frequency is missing, e.g. due to transmission over a telephone line, the voice signal is applied to a set of band pass filter circuits C1 to C7, each consisting of cascaded filters F and limiters E, the pass frequencies of which are such that each filter circuit passes at most, one harmonic of the fundamental frequency. The outputs of the filter circuits are connected via frequency dividers 2 to 12, and gate circuits, Al to All, to counter circuits 13 to 23 and the gate circuits are controlled by a logic circuit CL, also fed with the outputs of the filter circuits, which determines, in accordance with the particular pattern of energized filter circuits, the range in which the fundamental frequency falls and enables the appropriate gate circuit to feed to a counter circuit a frequency corresponding to the fundamental frequency of the input signal. A filter arrangement for dealing with speech signals with fundamental frequencies in the range 100-350 c/s is described, and appropriate logic circuits to enable the fundamental frequency to be determined are described with respect to Figs. 6 to 20 (not shown). A simplified form of frequency detector which handles only fundamental frequencies in the range 150-270 c/s. is shown in Fig 23, in which filter chains C8, C9 and C10, respond to frequency bands 300- 380, 380-460, and 460-540 c/s respectively. Each filter chain comprises band pass filters F8, F<SP>1</SP>8 &c., half wave rectifiers R8, R<SP>1</SP>8 &c., and limiter circuits E8, E<SP>1</SP>8 &c. providing discrimination against noise and emphasis of any harmonic of the input signal present. The logic circuit CL in this embodiment is such that the measurement is effected on the lowest frequency harmonic present, with all higher harmonics in higher frequency channels blocked by the gates 30 or 36.

Abstract: 881,860. Magnetic amplifiers. COMPAGNIE INDUSTRIELLE DES TELEPHONES. Dec. 18, 1958 [Dec. 21, 1957], No. 40913/58. Addition to 871,623. Class 40 (9). The response time of the magnetic amplifier of the parent Specification is improved by the provision of two magnetic cores, the output windings of which are connected in parallel and fed with out-of-phase pulse trains and by the omission of the smoothing condenser. As shown, two cores a, b are provided with feedwindings 1a, 1b fed with out-of-phase pulse waveforms Ea, Eb, control windings 2a, 2b, feed-back windings 3a, 3b and bias windings 4a, 4b. Fig. 4 illustrates the mean output current/control ampere-turns characteristic of each core. Due to the bias provided by the battery Uo the emitter current follows the characteristic of Fig. 5. The collector current follows a similar characteristic but is restricted to a maximum value, as shown at I 1 , Fig. 6, attained when the collector and base acquire the same potential. In Fig. 3, curves 1, 2, 3 illustrate the respective core output currents and the combined current. The effect of the very short breaks in the emitter current is eliminated by carrier storage in the transistor so that a steady collector current output is obtained. Feed-back may be connected in over terminals M, N, P, Q if desired.

The process may be operated batchwise or continuously and a stabilizer or polymerization inhibitor may be present during the cracking operation. The amidation reaction may be carried out at 75-100‹ C. in the presence of 0À1-10 moles of polyol per mole of ester. Alternatively the ester of the beta-ether substituted carboxylic acid may be reacted with said polyol in the presence of an acid to form an ester of said polyol, which is then reacted with an N,N-dialkylamine to form the amide. The cracking operation is suitably effected at 300-500‹ C. and a pressure of between 50 and 760 mm. Hg and the acidic catalyst preferablycontains SiO 2 , optionally with the addition of oxides of aluminium and iron. The beta-alkoxy alkanoate starting material may be prepared by alkoxylating an alkyl acrylate in the presence of a base and an alkanol, and the alcohol used in the alkoxylation reaction is preferably the same as the alcohol portion of said alkyl acrylate. The polyol may be continuously recycled to the amidation reaction, and the alcohol from the catalytic amidation reaction product and the catalytic cracking reaction product may be combined for recycling to the alkoxylation reaction zone with said alkyl acrylate. Specific examples describe the production of methyl #-methoxypropionate, the amidation thereof with dimethylamine to form N,N-dimethyl #-methoxypropionamide, and the cracking of the latter to form N,N-dimethyl acrylamide.

A bi-stable circuit operable with unipolar input signals comprises a tunnel diode 13 in shunt with the base-emitter circuit of a transistor 14, and another diode 15 applying negative feedback from collector to base. When the transistor is non-conducting, the VI curve for the diode 15 intersects that of the tunnel diode in its low-voltage region. A negative input pulse lifts the curve of diode 15 above the peak point of the tunnel diode curve, and the intersection now occurs at the valley point. The transistor and diode 15 now conduct and an output is obtained at 26. The next negative pulse lifts the curve of diode 15 once more, but on termination of this pulse the stored charge in the transistor drives a reverse current through dicde 15 to lower its curve below the original level and switch the tunnel dicde back to its original state. The circuit may be driven by the monostable tunnel diode circuit of Specification 1,057,821. It may also be used as a scale-of-two divider.
