Patent GB-915171-A (GB)
Title: Method and device for taking paper or other sheets off a stack
IPC: B65H3/36
Filed: 1960-08-05
Abstract: 915,171. Sheet separators. ZAVODY V. I. LENINA PLZEN. Aug. 5, 1960 [Aug. 13, 1959], No. 27159/60. Class 100 (1). A suction sheet-separator comprises a carrier for a suction head, means for mounting the carrier for oscillation towards and away from the sheet stack, a suction head rotatably mounted on the carrier to rotate about an axis fixed in relation to the carrier, and a rotary cam co-operating with the carrier to produce oscillation thereof. As shown, the suction head 13 is carried by a segmental member 12 keyed to a shaft 11. The shaft 11 is journalled in bushes carried by one arm of a two-armed lever 8 rotatably mounted on a shaft 7. The shaft 9 is driven so as to rotate the segment 12, gearwheels 3, 5, 9 connecting it to a driven shaft 2; the gear-wheel 5 is freely rotatable on the shaft 7. A cam 4 on the shaft 2 engages a cam follower 18 carried by the other arm of the lever 8 and held in contact with the cam by a spring 19. As the shaft 2 rotates it causes rotation of the shaft 11 and oscillation of the lever 8 with the result that the suction head 13 follows a distorted circular path (Fig. 3, not shown). The head 13 engages a sheet at the bottom of a stack at position a, moves downwards to position b and then carries the sheet round to position c where the suction is cut off and the sheet is transferred to other sheet feeding means. Alternatively the suction may not be cut off until the sheet is disposed substantially horizontally beneath the shaft 11. Specification 729,892 is referred to.

Title: Improvements relating to electrically-operated two state devices especially for storing binary digital data
Inventor: STEPHENSON GEOFFREY HUSON
IPC: C25B11/10
Filed: 1953-10-03
Abstract: 796,993. Digital-data-storage devices. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Sept. 22, 1954 [Oct. 3, 1953], No. 27178/53. Class 106 (1). [Also in Groups XXXVII and XXXVIII] An electrically-operated two-state device, especially for storing binary digital data, comprises a conductive member the magnitude of the current in which determines the condition of the device, first and second unilaterally conductive paths connected to one end of said member, a third unilateral conductive path connected to the other end of said member, means biasing the ends of said paths remote from said member in such manner that potentials simultaneously applied to the biased ends of two paths are required to vary the current in said member in one sense, whereas a potential applied to the biased end of one path alone can vary the current in the opposite sense, and hold means for maintaining the current in said device through one at least of said paths in response to a variation of the said current in the increasing sense. Each two-state device comprises an electro-mechanical relay having a control winding 1, Fig. 2, and forms a basic storage unit for one binary digit. Normally each terminal A, B and C is held at a positive potential and no current flows in the relay coil. In this condition the storage unit is said to be storing a " one." The storage unit is cleared, i.e. the relay coil made conductive, by applying a negative clearing pulse to the terminal C, which causes the relay contacts to change over, and, in particular, causes a contact 5 to close, thus completing a holding circuit which retains the relay energized even when the negative clearing pulse ceases. Data is entered into a storage unit by applying simultaneously a negative data pulse together with a negative selecting pulse to terminals A and B respectively. Twenty of these basic storage units arranged in the form of a 4 X 5 matrix, Fig. 3, provide a store for four five-digit binary numbers, each of which is applied in parallel form to terminals A0, A1, A2, A3 and A4, and enters the storage units of that row which is selected by a negative pulse applied, simultaneously with the number, to one of terminals B1, B2, B3 and B4. Any row can be cleared by applying a negative clearing pulse to one of terminals C1, C2, C3 and C4. The matrix store is said to be for use in an automatic device for controlling machine tools and a circuit is given (Fig. 1, not shown) in which a second contact on each relay of each row either switches into, or out of series, secondary windings on a transformer to produce an analogue voltage whose amplitude represents the value of the number registered in the corresponding row of the matrix. Specifications 731,650, [Group XXXVIII], 796,994, [Group XXXVI], and 796,995, [Group XXXVIII], are referred to.

Title: Echo traps
IPC: H04M9/10
Filed: 1975-06-27
Abstract: 1510162 Echo suppressors SIEMENS AG 27 June 1975 [24 July 1974] 27285/75 Heading H4R In an echo suppressor provided on the four wire side of a hybrid junction a normally transmissive blocking device 3, Fig. 6, is provided in the transmit path together with an attenuation element 4 in the receive path, with a switch 41 which is normally in a position to by-pass the attenuation element. A control circuit detects a signal in the receive path and, in the absence of signal in the transmit path, causes the blocking element 3 to block the transmit path. When a signal is detected in both paths operation of blocking element 3 is inhibited but the switch 41 is operated to insert the attenuation element, but is arranged so that as the signal in the transmit path increases relative the signal in the receive path the attenuation of the attenuation element is reduced and/or the switch 41 is allowed to revert and by-pass the attenuation element. As described the signal in the transmit and receive paths can be compared in comparator 8 and the output caused to increase the attenuation 43 in the control path of a compressor 42, 43, 4, or, Fig. 2 (not shown) the output of comparator 8 can be used to inhibit the operation of AND gate (47) controlling switch 41. Alternatively control of the attenuator 43 in the compressor 42, 43, 4, can be effected via a threshold device coupled either to the output of comparator 6, Fig. 4 (not shown) or the output of signal detector 62, detecting the signal in the transmit path, Fig. 5 (not shown). A further modification, Fig. 4, includes a variable gain amplifier 71 in the transmit path signal detector circuit and a variable attenuator 73 in the receive path signal detector circuit which are both controlled in accordance with signal level in the respective path via a storage control device 70 which is blocked by controller 60 during duplex operation. The arrangement varies the control sensitivity in accordance with the hybrid junction attenuation. A delay device 65 is provided in the receive path speech detector to compensate for the delay through the hybrid junction.

Abstract: 832,413. Automatic power factor control systems. LONDEX Ltd. (Deutsche Londex. G.m.b.H.). Sept. 2, 1957, No. 27537/57. Class 38 (4). In a power factor regulating system a device responds to change of P.F. and operates several contacts to provide regulating steps in which contactors connect or disconnect capacitors-in number, fewer than the number of contactsthe energization of one contactor being controlled by auxiliary contacts on the contactor for another capacitor. The rotor of the P.F. meter M is arranged to rotate an annular tube AT containing mercury which, depending on its angular position, completes circuits from contact Ro to contacts R 1 <SP>1</SP> to R 7 <SP>1</SP>. The contactors Col, Co2, Co3 are energized in a prearranged manner by the successive closing of these contacts and introduce the capacitors C 1 , C 2  and C 3  having comparative values, for example, 1, 2 and 4 units, in parallel with the load circuit for P.F. correction. The number of combinations of the capacitors is the same as the number of contacts and gives a progressive increase in correction. The block NV comprises a safety device to remove the capacitors from the load circuit should the supply fail and to ensure that they are reconnected progressively when it is restored. Relay N is de-energized and open-circuits contact R 0 , thus disconnecting the capacitors and also reverses the connections to the P.F. meter. When the supply is restored the tube AT is reversely rotated until, when R<SP>1</SP> 1  contact is broken, relay n is de-energized and through contact On relay N re-energized. The P.F. meter rotates back to its original position reconnecting the appropriate capacitors. Instead of the device NV an arrangement of time delay relays IDR may be used in the event of a supply failure. Specifications 537,874 and 774,402 are referred to.

Patent GB-649428-A (GB)
Title: Improved process for preparing hexachlorocyclohexane
IPC: C07C17/02
Filed: 1948-10-27
Abstract: Benzene is chlorinated without exposure to radiation to give benzene hexachloride by bringing together water, benzene, chlorine and a basic substance, at least 50 per cent of the weight of the water being introduced as ice, preferably at least 75 per cent or even 90 per cent.  Chlorine may be passed into a mixture of the other components, or else the water, ice and basic substance may be first treated with chlorine (thereby forming hypochlorite if an alkali hydroxide is used), benzene then added and the rest of the chlorine then introduced.  The chlorine may be introduced wholly or partly in the liquid form or as its crystalline hydrate.  If an alkali hydroxide is used as the basic substance, it is preferably added as an aqueous solution, to avoid undesirable generation of heat. Suitable proportions are 100 parts by weight of ice, 1-1.3 of sodium hydroxide in 2-8 of water, 12-100 of benzene and 25-30 of chlorine. When an excess of benzene is used, the product is a benzenic solution of the hexachloride which can be used for making insecticidal preparations.  Introduction of chlorine is continued until its absorption becomes slow, usually after 10-15 minutes.  Stirring is not necessary, but it is desirable to stir at the end of the reaction and to continue after the introduction of chlorine has been stopped, to facilitate reaction of the last traces.  The product then consists of a benzene solution of the hexachloride, with or without solid hexachloride, covered by an aqueous layer.  The benzene may be removed if desired by steam distillation, or else the mixture is allowed to stand, the layers separated, and the benzene distilled off if desired.  By using a vessel with an opening at the bottom, the process may be carried out continuously.  The amount of hexachloride in the product may be estimated by titration with alcoholic potash, when it is hydrolysed to trichlorbenzene.  The proportion of the gamma isomer is about 15 per cent, as determined by biological and cryoscopic experiments.  Examples are given of the process.
