Abstract: 895,802. Endless belt conveyer delivery shoots; filling trains of railway wagons. HANMADE CONVEYOR CO. Ltd. Dec. 23, 1959 [Nov. 6, 1958], No. 35614/58. Classes 78 (1) and 78 (4). Quarried material, e.g. coal, is delivered from a conveyer belt 8 into trucks 1 by a shoot assembly comprising a screening plate 13, a hopper 3 which receives the finer material and delivers this into the trucks as they move from right to left, as shown, to form a layer on the floor of each truck, and a shoot defined by side plates 14 which delivers the coarser material on to the layer of finer material already deposited in the trucks. It is said that this arrangement greatly reduces breakage of the coal or other quarried material. The hopper 3 has an outlet which is closed automatically when between adjacent trucks by a door 5 secured to an arm 7 which is pivoted at 6 to the hopper and is engaged by the front and rear walls of the trucks. Alternatively an hydraulic piston-andcylinder may be used for operating the door. The shoot also has a pivoted door 15 which is operated by an hydraulic cylinder 16. The material passes from the belt 8 to the plate 13 via a receiving plate 12 secured to a pivoted lever 10 acted on by a spring 11 and adapted to operate a switch to stop the belt 8 should material jam between the plate 12 and the belt 8.

Title: Collapsible containers fitted with inlet valves
Inventor: CISCO RICHARD LEE
IPC: F16K21/00
Filed: 1965-08-19
Abstract: 1,111,301. Filling and emptying tanks. PARKER - HANNIFIN CORPORATION. 19 Aug., 1965, No. 35676/65. Heading B8T. [Also in Divisions F2 and G3] The top wall of an inflatable tank T carries a valve 1 and an inlet/outlet port 4. The valve comprises a main closure member 7, 11 defining a chamber 10 that communicates with the port 4 via a restricted tube 18 and with the tank via a check valve 16 and pilot valve 14 biased to the open position by a spring 20 acting through a diaphragm 31. A stem 37 abuts the plate 24 carrying the pilot valve and is connected to one end of a cable 38 the other end of which is connected to the base of the tank. When the tank is being filled, the pilot valve is open and the supply pressure opens valve 7 against a spring 9. As the tank is being filled, the top wall rises carrying with it the valve 1. When the cable 38 prevents further rising of the pilot valve, continued movement of the top wall allows spring 23 to seat the pilot valve and the resultant increase in pressure in chamber 10 closes the main valve. If the cable breaks, the increased pressure in the tank moves diaphragm 31 to allow the pilot valve to seat. When it is required to discharge the contents of the tank, a negative pressure in port 4 exhausts chamber 10 and allows tank pressure acting above diaphragm 11 to open the main valve. In Fig. 2, not shown, cable 38 is omitted and the spring- loading on diaphragm (31<SP>1</SP>) is made adjustable. In Fig. 3, not shown, after the pilot valve (57) and main valve (53) have closed as a result of tank pressure acting on diaphragm (59), and after removal of the tank filling line to expose passage (51) to ambient pressure the main valve is kept closed by fluid at tank pressure flowing to chamber (55) via a check valve (70) and line (71), a check valve (72) serving to prevent leakage into the passage (51). When the negative pressure is applied to discharge the tank, it acts via passage (69) to reseat a valve (65) against spring (66) on a seat (75) thereby putting chamber (55) in communication with line (69) via chamber (68) and allowing tank pressure above the diaphragm carrying the main valve to unseat the latter. During closure of the main valve, the latter varies the effective size of restricted passage (73) to prevent shocks. In Fig. 4, not shown, when the tank pressure reaches a predetermined value it acts on diaphragm (110) to seat pilot valve (106) thereby allowing pressure to build up in a chamber (86) via line (88) to seat the main valve (85). A check valve (105) is provided in the inlet (87), the latter being held open by a pipe fitting during discharge. A cover (122) is provided.

Filed: 1970-07-24
Abstract: 1322978 Adder WESTERN ELECTRIC CO Inc 24 July 1970 [25 July 1969] 35884/70 Heading G4A [Also in Division H4] In a time division communication system, signals from a pair of lines in communication are transferred to corresponding highways during a first time slot and added together and signals derived from the resultant are transferred from said highways to said pair of lines during a subsequent portion of that time slot. Several embodiments are described. Each relates to a PBX switch unit, a plurality of such units being controlled by a common control at a remote location as described in Specification 1,029,204. Each embodiment employs separate highways for " go " and " return ". In one form as shown highways 115 and 120 simultaneously receive signal samples from a pair of subscribers 500, 503 in communication during the first half of a time slot, store these signal samples in register 116 and 121 and forward each signal sample to the other subscriber of the pair during a subsequent time slot. Subscriber individual equipment between its transceiver 105 and the substation 500 encodes speech samples to P.C.M. form, e.g. on a logarithmic scale, on transmission and decodes a component of the signals returned. The two samples simultaneously fed from the two substations to the two highways are added in digital adder 305 and returned via a buffer 310 to both highways. The resultant sum is fed to the transceivers of both substations where before decoding, the locally originated coded sample is subtracted from the sum to obtain the signal from the other subscriber. An additional sum buffer 510 allows the sum to be recirculated for the addition of further signal samples from other subscribers added in pairs during successive time slots to provide conference facilities. The subscriber gates 107 &c. to be opened are controlled by a cyclic store 150, 150<SP>1</SP> and associated read out register 140, 140<SP>1</SP> and decoder 130, 131. The contents of the cyclic store are updated during call processing by the common control. During a conference call the signal sample sum may be returned to the conferees in pairs in successive time slots or auxiliary readout registers may be provided for the cyclic store to enable more subscriber gates to be opened simultaneously. The cyclic store and read out circuitry may be divided as shown and each highway 115 and 121 provided with additional adders 700 and 710 and associated buffers so that if one of the highways goes out of service the other can continue using two or more time slots per call on a reduced service basis.

Title: An arrangement for transmission of information without errors
IPC: H04L1/18
Filed: 1960-10-21
Abstract: 888,983. Type printing telegraphy. STANDARD TELEPHONES & CABLES Ltd. Oct. 21, 1960 [Oct. 22, 1959], No. 36214/60. Class 40(3). In a telegraphy system in which a transmitter transmits characters in a code permitting error detection at a receiver, the characters are stored in groups at both the transmitter and receiver and the ordinal number of any incorrectly received character is recorded in an error store. After the transmission of each group of characters the receiver causes the transmitter to re-transmit at least the characters in which an error was detected, these characters, if correctly received, replacing the original incorrect characters. In a first embodiment, Fig. 1, a complete group of characters is re-transmitted when an error is detected. At the transmitter, signals from a teleprinter 11 are recorded in a store 12 from which the code signals are read out by a scanner 13 and passed to a transmitter 14, whence they pass via a switching unit 15 and are transmitted. At the receiver, the signals pass through a switching unit 55 to a receiver 54 which feeds an error detector 56 and a store 52. If an error is detected the position number N of the incorrect character in the group is recorded in an error store 57. When a complete group has been received, indicated by the reception of a special signal, units 15, 55 are switched. Unit 61 then detects the presence of a signal in the error store 57 and a return transmitter 59 transmits a rerun request to the transmitter, whereupon units 15, 55 are returned to their original state and the complete group is retransmitted. When the retransmitted signals are received only those characters which were previously incorrectly received are passed to the store 52, where they replace the incorrect characters. This procedure is repeated until the complete group of characters is correct, whereupon the stored characters are passed from the store 52 to the printer 51 under the control of a scanner 53. In a second embodiment, Fig. 2 (not shown), only the characters in which an error has been detected are retransmitted. The circuitry is substantially similar to that of Fig. 1 but includes a scanner at the receiver for scanning the error store to cause the return transmitter to request repetition of particular characters, and a scanner at the transmitter for extracting those characters from the store for retransmission. Two stores may be provided at the receiver so that, alternately, one is receiving characters while the other is connected to the printer for printing the information stored in it.
