Title: Dictation machine
IPC: G11B25/06
Filed: 1968-12-13
Abstract: 1,224,908. Dictation machines. INTERNATIONAL BUSINESS MACHINES CORP. 13 Dec., 1968 [19 Jan., 1968], No. 59289/68. Heading G5R. A dictation reproducer includes a "recall" mechanism whereby upon halting playback the head and record are automatically back-spaced ready to repeat the last few words when playback is restored. A magnetic belt 2 is slipped over a mandrel 11 and lever 10b moved leftwards to draw the belt into the machine over rollers 63, one of which is also shifted to tension the belt via linkage 50. Various latches 73, 74, 86 are also operated via link 60 to energize the motor to restore, via lead screw 100, the head carriage 103 to a "zero phase" position, determined by engagement of members 84, 84a of clutch 93, while the belt continues to be driven until a hole is sensed at 97 to stop the motor. If no hole is provided, the record is reversed and stops at the desired location (not detailed). During this time the head 82 is spaced from the belt by link 79 and is zeroed by lead screw 95 after removal of the previous belt (not detailed). Depressing the right of foot controller 8 engages forward drive of belt and carriage 103 via screw 100 and pawls (Fig. 3, not shown). When released, the motor automatically reverses to back-space the head 82 and belt over the last 0-5 words according to the setting of lever 19 which operates a movable stop 242 for a return biased rack 243 which, when solenoid T is energized, is driven by pinion 260 until it breaks contacts TC, thereby stopping the motor. Recall may be terminated by depressing controller 8 again to short-circuit the motor and to restore normal drive after a short delay. Depression of the left or top of controller 8 respectively reverses or advances the system over 10 or 20 words, according to the position of switch 27a, as a single or succession of steps. The machine auto-stops at the end of play and is restarted by moving the head carriage via lever 16a associated with an index slip 15a. Speed, tone and volume controls 22, 29, 31 are provided and the belt may be erased via control 40a, automatically stopping at the end of erasure. The audio amplifier is muted during non-transducing operations.

Filed: 1968-12-23
Abstract: 1,223,929. Ammonia synthesis. CHEMOPROJEKT, PROJEKTOVA, INZENYRSKA A KONSULTACHI ORGANISACE, and CHEMICKE ZAVODY NARODNI PODNIK. 23 Dec., 1968 [22 Dec., 1967], No. 61069/68. Heading C1A. [Also in Divisions B1-B2 and F4] A machine of gases, e.g. H 2  and N 2  in the synthesis of NH 3 , is caused to flow from operation mains 1 via pipe 3 and valve 4 into injector 8 where it serves as a driving medium for sucking in hot synthesis gas discharged from heat exchanger 8 via discharge pipe 6 and valve 7. The resulting mixture is then passed from injector 5 through heat exchangers 8 and 9, and into heat exchanger 10 from where it passes into and through external heater 11 where it is electrically heated. The hot gas then flows through and heats catalyst beds 12 and 13, heat exchanger 10, catalyst beds 14-17, heat exchanger 9 and finally into heat exchanger 8 from where the gas, now considerably cooled, is sucked into injector 5 by the passage into the injector of the initial cool gases entering the system from 1. In this way the synthesis gas entering up through the system is heated by the hot synthesis gas which is flowing down through the system, and also, the various catalyst beds and heat exchangers comprising the reactor itself are heated by the continuous flow of hot gas until of a sufficient temperature for the reaction to commence.

Title: ARRANGEMENT, e.g. FOR HANDLING RADAR TARGET INFORMATION
IPC: G01S13/16
Filed: 1969-12-17
Abstract: 1292639 Pulse radar TELEFONAKTIEBOLAGET L M ERICSSON 17 Dec 1969 [20 Dec 1968] 61569/69 Heading H4D [Also in Division G4] An arrangement is such that during a signal at a first inlet a signal at a second inlet produces a signal at an outlet and the arrangement is locked against further response to subsequent signals at the second inlet during the signal at the first inlet wherein a register is provided to store the time of occurrence of said signal at the outlet. Video pulses from a radar receiver are fed to an AND gate A on input I 2 ; if a signal is present on I 1  and the output of bi-stable C is in its normal ONE state, the video pulse is passed to a pulse generator B which produces a pulse at its output. This pulse is fed back to C which then changes its output to the ZERO state, thereby closing gate A to any further video pulses. When the signal at I 1  is removed, inverter H causes the bi-stable output to return to its ONE state. A time counter E having p digits comprising bi-stable elements is reset to zero and starts to count when a radar pulse is transmitted. Each digit has a ONE and a ZERO output each of which feeds one input of a series of 2p AND gates D. The second input of each gate D is the output from the generator B. The outputs of the gates D feed the ONE- and ZERO-setting inputs of a p digit register F. Thus when a video pulse causes an output from generator B, the instantaneous time indicated by counter E is read into register F. The time represents the range of the target.

Title: Detecting solids in a fluid
IPC: F02B3/06
Filed: 1978-08-26
Abstract: A device for detecting the presence of solid impurities within a pressurised fluid includes a housing with a fluid passage in which a filter element 54 is located. One end of the passage 34 is open to the pressurised fluid 30 from pump 12 and the other end 40 to a low pressure input 20 to the pump.

Title: Apparatus for compacting material
IPC: B30B9/30
Filed: 1979-01-20
Abstract: Shredded paper for use as animal bedding material is compacted for packing by a reciprocating hydraulic compacting ram (8) which displaces the material through a compaction chamber (6) into an ejector chamber (10). The pressure in the compacting ram is monitored by a pressure switch (18), and when a threshold pressure corresponding to a desired degree of compaction is reached a limit switch (LS2) is effectively primed to trip the operation of an ejector ram (12) upon completion of a compaction stroke to eject the compacted material from the ejector chamber (10). If said threshold pressure is not reached a second limit switch trips the reversal of the compacting ram (8). <IMAGE>

Title: Vibration Motor Control
IPC: H02N2/12
Filed: 1979-04-24
Abstract: A vibration motor comprises adjoining working piezoelectric cell 5 and feed-back piezoelectric cell 7, the former being in contact with one stage 4 of a concentrator 3 of ultrasonic vibrations, whose driving stage 2 is pressed to the surface of a rotor 1. The working piezoelectric cell 5 is connected with the output of an electric oscillator 6, while the feedback piezoelectric cell 7 is coupled to the oscillator sync input. The rotation frequency of the rotor is controlled by changing the hold-down force pressing the driving stage 2 of the concentrator to the rotor surface and/or by maintaining the amplitude of ultrasonic vibrations of the concentrator at a preset level, or by both these methods concurrently. As shown, the hold down force is varied, using an electromagnet 14, in accordance with the measured rotor rotational frequency, as measured by device 11. <IMAGE>
