Title: Electro-optical oscillator
IPC: H03B17/00
Filed: 1965-12-23
Abstract: 1,072,240. Electro-optical oscillator circuits. NATIONAL CASH REGISTER CO. Dec. 23, 1965 [Jan. 25, 1965], No. 54521/65. Heading H3T. A variable frequency oscillator comprises a chain of stages each including a photo-sensitive element and a light-emitting element each stage being arranged to transmit a signal with a delay, and a feedback circuit from a selectable point in the chain to cause the circuit to oscillate at a frequency depending upon which point in the chain is selected. In Fig. 1, when electroluminescent element EL2 emits light the photo-conductor PC1 causes EL1 to emit light so that in this manner the luminescent elements of the chain successively emit light. When stage T3 emits light a photoresistor PC2.3 effectively short-circuits EL2, extinguishing luminescent device EL2 and the others in succession. Accordingly a continuous pulse train may be derived from a photo-conductor PC4. By moving switch S2 to select an alternative feedback point the frequency of oscillation may be varied. The individual stages of the chain may be made regenerative. Thus in Fig. 2 (not shown) a photo-conductor is inserted between PC1 and EL1 of each stage and illuminated by EL1 to provide the regeneration. In Fig. 3 (not shown), a photo-conductor (PC7) is connected in parallel with each photo-conductor PC1 (now referenced PC6) and this is illuminated by the associated electroluminescent device to provide the regeneration. In Fig. 4 each stage comprises two electroluminescent devices and two photoconductors, the regenerative feedback occurring between device EL5 and photo-conductor PC12. The light coupling between the stages may be replaced by an electric coupling if (as in Fig. 5) a pair of electroluminescent devices (PC18, PC19) are provided in each stage to receive the output from the luminescent elements and a connection is made between the mid-point of the pair and the mid-point of the succeeding stage.

Title: Walking beam cooling beds
IPC: B21B43/02
Filed: 1972-11-28
Abstract: 1396976 Cooling beds DAVY-LOEWY Ltd 11 Jan 1974 [28 Nov 1972] 54895/72 Heading B3M [Also in Division B8] A walking beam cooling bed has a series of movable beams 2 which are located between fixed beams (not shown), and are shifted vertically and horizontally by independent assemblies, the beams being interrupted in their downward movement when they are level with the fixed beams. This interruption allows hot metal plates to be supported by both sets of beams for a period before they are shifted along the bed. The beams 2 are movable horizontally by hydraulic piston and cylinder units (not shown), and are supported by rollers 4 on beams 6 carrying rams 8. When the beams are shifted back and forth horizontally by links 32, the ramps move over rollers 10 to raise and lower the beams 6. The beams 2 are therefore moved vertically, but not horizontally (due to the rollers 4). The links 32 are shifted by levers 30 oscillated by an hydraulic unit 18. To prevent the weight of the workpieces and beams from putting an unnecessary strain on the unit 18 when the vertical movement of the beams 2 is interrupted, the interruption is effected during only the downward movement. A pivotable detent 48, Fig. 2, is shifted into the path of a slider 40 to lock the links 32 in a central position (corresponding to the fixed and movable beams being level), and serves to take the loading off the unit 18.

Title: Detection and correcting of errors in electronic pulse-coded data
IPC: G11B20/14
Filed: 1973-12-03
Abstract: 1423675 Storage systems HONEYWELL INFORMATION SYSTEMS Inc 3 Dec 1973 [4 Jan 1973] 55847/73 Heading G4C In a multichannel storage system in which data words represented by at least one transition in a bit interval in each of the channels are read by amplifiers 10a-10j (Fig. 1) into serially connected deskewing buffers 22, 24, 26 each having, for each channel, a pair of flip-flops (e.g. RSO11, KSA10, Fig. lb, not shown) one of which is set to its "1" state by the read data, errors in each word due to a dropped bit may be corrected by setting each of the flip-flops in any channel in which a transition is not detected to their "1" state and using information from a parity channel to correct the data as it is transferred to an output register 30. If more than one channel is in error a flip-flop (32-37, Fig. Id, not shown) is set to its "1" state to indicate that an uncorrectable error condition occurred. The system is described for phase encoded data on a magnetic tape, pseudo clock circuits 14 applying clocking signals to synchronizing circuits to derive clocking signals to gate the data into the first of the buffer registers 22. When the flip-flops of a stage (e.g. stage 24) are both at zero, AND gates (e.g. gates 24-4, 24-14, Fig. 1b, not shown) are enabled to permit transfer of the data between stages (e.g. stages 22, 24) at a clock pulse. When a bit is dropped, as well as both the flip-flops being set to their one state, for channels 1, 2, a first signal (RSMDB4A, Fig. lb, not shown) is "1", when both channels 1 and 2 have dropped a bit, a second signal (RSMDB140) is "0" if channel 1 has dropped a bit and a third signal (RSSDB4A) is "1" when neither channel has dropped a bit. These signals are fed to error detector circuitry 32 which also derives parity information for the received data to apply correcting signals to flip-flops (30-1, 30-9, Fig. ld, not shown) in the output register.

Abstract: 1,224,297. Applying adhesive tape. MOLNLYCKE, AB. 17 Nov., 1969 [19 Nov., 1968], No. 56158/69. Heading B8F. An apparatus for applying lengths of adhesive tape 30 to a moving surface 2 comprises rollers 23-26 for drawing the tape 29 from a roll 28, reversing mechanism 55, 57 and a rotatable applicator foot 14. The rector-shaped applicator foot 14 is driven from a driving shaft 8 through a lost-motion coupling at a peripheral speed slightly less than that of the surface 2, so that after it has initially applied the leading end of a severed length of tape 30 to the surface it is rotated by frictional contact with the tape to press the entire length of the tape on to the surface. Feed rollers 24, 26 are driven intermittently from the shaft 8 by way of a crank and one-way clutch drive. Friction in the oneway clutch causes the rollers to be given a slight reverse rotation during reverse movement of the crank arm to an extent permitted by play between abutments of a friction brake provided on the output side of the one-way clutch. This slight reverse movement of the feed rollers prevents the leading edge of the unsevered tape from adhering to the reversing mechanism 55, 57. The reversing mechanism has a stationary blade 55 and a pivoted blade 57 which is actuated by a cam on the driving shaft.

Abstract: 1,193,178. Mineral-mining machines. MAVOR & COULSON Ltd. 5 Dec., 1968 [16 Dec., 1967], No. 57240/67. Heading E1F. For preventing of a rotary cutter 2 of a miming machine engaging with any abnormally hard obstruction to its passage through a mineral seam a cutting disc 32 of slightly larger diameter than the cutter is co-axially associated with the cutter. In use of the machine, the disc on encountering an obstruction immediately tends to advance around the periphery of the obstruction and in so doing causes an increase in the pressure in the hydraulic system for actuating the means 4, 5 controlling the position of the cutter 2 in the seam. This pressure increase causies through a 'relay system 23 switching of a change over valve 14 to cause reversal of the supply of pressurised fluid to the means 4, 5 so that the means are actuated to appropriately move ithe cutter until the disc clears the obstruction. On ithe disc clearing the obstruction the pressure build up by the disc on the system is removed, the valve is again switched, and the cutter is restored to its previous or to an appropriate operating level in the seam. Such a controlled cutter may be provided at each end of the machine so that such cutters may simultaneously and automatically cut along the floor and roof contours of a seam.
