Abstract: 1295466 Non-autochange gramophone PIONEER ELECTRONIC CORP 13 Nov 1969 [13 Nov 1968 3 July 1969] 55702/69 Heading G5R In a non-autochange gramophone, after positioning a record and operating appropriate speed and size controls, and auxiliary motor controls the initial positioning of the pick-up arm and its return to a rest after the record is played. On energizing the gramophone the auxiliary motor is energized and this drives a contact disc co-operating with a printed circuit, Figs. 13-15 (not shown), to supply energy to the turntable drive motor and to open the circuit to the auxiliary motor when a disc 127 coupled thereto has rotated 180 degrees. The disc 127 is coupled by shaft 134 to a member 135 which is pivotally mounted with members 136, 138 and 142 on shaft 133. Members 135, 136 and 138 are frictionally coupled and stop member 142 is rotated by rod 148 from the record size control to move one of the notches 142a-142c into engagement with a detent on spring 143 in dependance on record size. As member 135 is rotated it moves member 138 which in turn moves a pin 157 coupled to the pick-up arm 122 which moves off its rest towards the record. This movement ceases when member 138 engages the edge of stop member 142 and the tone arm stylus over the start groove of the record. Continued rotation of member 135 whilst the disc 127 moves through 180 degrees moves arm 136 into engagement with stop 146 and brings a lower cam portion 135b of member 135 below support pin 178 of the support arm so that the tone arm stylus is lowered into engagement with the record. As the pick-up moves towards the record centre a screw 61 on an arm 59 fixed to the tone arm shaft engages lever 62 and moves the end of a sensing lever 65, frictionally coupled to lever 62, towards a pin 11a rotating with the turntable. At the end of the record the pin engages the lever 65 and rotates it and lever 62 in an anticlockwise direction whereby a switch (not shown) is operated to energize the auxiliary motor. Member 135 is now rotated in the opposite direction and raises the pick-up arm as the higher cam portion 135a thereof moves beneath support pin 178. Arm 136 now engages pin 157 and moves the pick-up arm back to its rest and arm 138 moves into engagement with stop 144. After the disc 127 has completed its 180 degrees movement the apparatus is returned to its initial "off" state. The pin 157 (or 57) which moves the pick-up arm is mounted on a member 56 which is urged by spring 58 into coupling engagement with the arm 59 made fast to the pick-up arm pivot. The angle between the member 56 and arm 59 is adjustable by screw 56a to adjust the precise point where the stylus is lowered on the record. When the stop member 142 is moved so that the spring detent engages notch 142d the member 138 is stopped before the pick-up arm leaves its rest so that the arm can be manually positioned before automatic lowering.

Abstract: 1333776 Ethylene production BRITISH GAS CORP 17 Nov 1971 [19 Nov 1970] 55102/70 Heading C5E Ethylene is made by (1) cracking the non- aromatic portion of a hydrocarbon feedstock, e.g. naphtha, in presence of hydrogen to produce a mixture of ethane and methane under such conditions that the proportion of ethane is maximized; (2) separating the ethane and cracking it to produce ethylene and hydrogen; (3) recycling recovered hydrogen for reaction with further feedstock. Hydrogen from the stage (1) product can be recovered with hydrogen from the stage (2) product by separating aromatics from stage (1) product and combining the remainder stage (1) product stream with the product stream of stage (2) and separating the combined streams to provide hydrogen for recycle, methane, ethane for feeding to stage (2), ethylene, and a residue of heavier hydrocarbons. The combined streams may be separated in a fractionation system comprising demethanizer, de-ethanizer and ethylene/ethane splitter. This system may be operated under pressure so that expansion of the overhead product of the demethanizer is used to provide self-refrigeration for separation of the hydrogen and methane.

Abstract: 1355497 Alarm systems LIGNIN ENG CO Ltd 4 Feb 1972 [12 Nov 1970] 53833/70 Heading G4N In an alarm system having one or more detectors, false alarms are reduced by preventing switching from PASSIVE to ACTIVE mode except when an all-clear signal is being received from a detector. As shown in Fig. 3, the detector is a normally-closed switch, e.g. operated by opening a door. In the PASSIVE mode, thyristor Th3 is conductive and provides a high level input across R4 which is fed to a logic element LE. When an operating switch (not shown) or auto programmer is set to ACTIVE, Th2 is turned on, so that C1 turns off Th3 and transfers the feed to the logic element LE from the detector in series with a flow restrictor RR1 and linked terminals XX. When the door is opened, the detector contacts open, turning off Th2 and giving a reduced input to the logic element LE which initiates an alarm. If there is an open circuit in the detector circuit when switching to ACTIVE, Th2 cannot be turned on so that Th3 is maintained conductive, preventing an alarm signal being fed to LE. If there is a short-circuit in the detector circuit, Th1 is turned on, energizing relay RL1 and breaking the supply to Th2. The restrictor RR1 may alternatively be connected in parallel with a normally-open detector. Closure of the detector contacts turns on Th1 energizing RL1 which turns off Th2 to provide an alarm initiating signal. A compensating resistor R5 is inserted by SOL1 when required. In Fig. 2, closure of a circuit including programme unit U1, relays RL5, RL6 and operating switch OS energize a transfer element RL3 if the normally-closed detector is in the all-clear condition. When the detector is opened, due to an abnormal condition, logic element RL4 is released to initiate an alarm. RL3 cannot be energized unless the detector is in the all-clear condition. A voltage-sensitive relay RL1 prevents energizing of the transfer element RL3 in the event of a short-circuit across the detector circuit. A further relay RL2 and diode 24 enable operation with normally-open detectors. Modifications.-Reference is made to fluid systems in which the flow is restricted by means of an orifice at each detector.
