Title: Indicator mechanism for indicating a variable parameter
IPC: G01K1/02
Filed: 1971-10-05
Abstract: 1330578 Indicating-apparatus; thermallyoperated electric meters FORD MOTOR CO Ltd 5 Oct 1971 [ 20 Nov 1970] 46226/71 Headings G1J and G1Q An indicating-mechanism 10 comprises a pointer 18 pivotally mounted within a housing 12, an actuator 40 secured to the housing and movable as a function of a parameter to be indicated and a coupling 50, 68 between the actuator 40 and pointer 18 allowing the pointer 18 to remain in the same position over a substantial range of movement of the actuator 40. The parameter to be indicated e.g. the temperature of the coolant of a vehicle I.C. engine is represented by a variable electric current applied to a heater coil 46 surrounding a leg 48 of a bi-metal actuator 40, Fig.3, with an ambient temperature compensating leg 42 rivetted at 44 in the housing 12. The pointer 18 is rivetted in the top of a pivot shaft 62, Fig. 7 with an axial opening 64 at the bottom to receive a pivot pin 52 fixed in the housing 12 in alignment with a pointer driving pin 50 on the actuator leg 48. The actuator 40 is coupled to the pointer 18 with lost motion by the pin 50 working in a slot 68 in a member 66 protruding laterally from the pointer pivot shaft 62 which carries a counterweight 70, Fig 5, biasing the pointer 18 towards a vertical position, which position is maintained throughout a normal range of coolant temperatures e.g. 180 F. to 210 F. and outside which range the pin 50 engages a side of the slot 68 causing significant movement to attract the operator's attention to an abnormal condition. In another embodiment, Fig. 4 (not shown) the pivot pin 52 for the pointer shaft 62 is positioned above the scale 16 so that the weight of the pointer 18 and its member 66 bias it to the vertical position without an additional counterweight. In each embodiment the leg 42 and pivot pin 52 may be fixed respectively to arms 58, 54 pivoted respectively at 60, 56 whereby the zero point of the pointer 18 with respect to the scale 16 may be pre-set. The mechanism may be used to draw attention to abnormally low engine oil pressures.

Title: Information indexing and retrieval processes
IPC: G06K1/18
Filed: 1974-10-29
Abstract: 1516310 Data storage and retrieval system: data input DATA RECORDING INSTRUMENT CO Ltd 28 Oct 1975 [29 Oct 1974] 46815/74 Headings G4M and G4H Data is recorded for retrieval by arranging a matrix array each location of which corresponds to a criterion, marking the appropriate position in the array for each criterion present in an item, recording the data from the array on magnetic tape in binary fashion with a "1" representing a mark and a "O" representing the absence of a mark, and recording an index value representing the item. The recorded data is subsequently searched for selected criteria and the index values are displayed when the selected criteria are detected. In one embodiment a form has locations corresponding to data about employees and appropriate locations are marked in accordance with, e.g. the employee's age, salary, status &c. Each form can be read by a scanner and data entered into a buffer register to be stored on a magnetic tape or data can be entered using a keyboard for storage on the tape. Each form has an indentity or index value. In a second embodiment data is entered using a light emitting diode display and a light pen. The diodes in the display are labelled using a partially transparent overlay (Fig. 5). The diodes are lit in succession by control circuitry (Fig. 6) containing an oscillator 150 and a shift register 101. Pulses from the oscillator advance counters 170, 180 enabling the columns and rows respectively of the array, shift data through the shift register 101 and enable pulse generator 160. Pulse generator 160 produces a short pulse which causes the addressed diode to flash for a short period. If the shift register stores a "1" then the corresponding diode is lit for a long period. Data can be stored in the shift register from an input register 40 or by using a light pen 60 and the display. The light pen is pointed at a selected diode and when the diode is enabled the light pen senses the short flash. This is lengthened in a Schmitt trigger 80, checked and entered into the shift register. The light pen can also be used to erase a "1" in the shift register.

Filed: 1964-11-18
Abstract: 1,091,512. Transferring blanks. EASTMAN KODAK CO. Nov. 18, 1964 [Nov. 18, 1963], No. 46991/64. Heading B3W. [Also in Division B8] A component clamping device, adapted to be mounted on a movable element of an assembly machine to grasp and convey a component, comprises a horizontal support member beneath which are carried a pair of support slides and above which is mounted a solenoid, a pair of parallel jaws adjustably secured one to each slide and extending outwardly therefrom relative to the solenoid which has a vertically drivable armature, and a pair of lever bars connecting the armature to the slides and being angled relative thereto for moving the slides relative to each other to grasp a component between the jaws. The jaws 54, 55, the slides 56, 57 and the solenoid are mounted on a tool-slide 18 which is received in a guide 32. The guide is bolted to the face of a wheel 30 and has a hole which receives a serrated wheel 15, to which it can be locked by a detent 37 operated by a solenoid 38. An eccentric pin 17 on the wheel 15 engages a slot in the tool slide 18, so that rotation of the wheel 15 causes reciprocation of the tool-slide in its guide 32. The wheel 30 is freely rotatable on a spindle 49 which is journalled in a bearing 48 in a main slide 24. The wheel 30 can be locked against rotation relative to the slide by a pawl 34 operated by a solenoid 35. The spindle 49, to which the wheel 15 is secured, also has mounted thereon a sprocket wheel 42 which is driven by a chain 14. The chain passes round a second sprocket 42, two idlers 43 and a drive sprocket 12 which is actuated by a stepping motor 10. The main slide 24 is supported, by a pair of guide rails 44, in a frame 13 and can be locked to a rack 26 on the frame by a pawl 28 operated by a solenoid 29. Operation.-With the wheels 15 and 30 locked, operation of the motor 10 drives the chain 14 to move the main slide 24 to a desired lateral position, in which it is locked by the pawl 28. The wheel 30 is unlocked and further movement of the chain 14 then rotates the shaft 49, the wheel 15 and the tool-slide 18 to the desired angle. The wheel 30 is then locked and the wheel 15 released, movement of the chain then rotates the wheel 15 relative to the tool slide to move the clamping assembly 21 and the tool slide 18 in the guide 32. The armature 80 is pulled by the winding against a spring 81 to open the jaws and is connected to the slides 56 and 57 by toggle links 78 and 79. The device can be used to transport a component (70), Fig. 2 (not shown), which is detached from a strip by a punch and die (74, 75), from the dieset to a sub-assembly 22. The sub-assemblies are each carried by a pallet 62 which is driven along a mono-rail 67 by a motor 66.

Abstract: 1,140,806. Wire or bond tensioning device. B. S. PALMER & CO. Ltd. 5 Sept., 1967 [27 Oct., 1966], No. 48186/66. Heading F2G. A wire or band tensioning device comprises a housing in which an hydraulically or pneumatically actuated piston 3, Fig. 1, is arranged so that a wire or band gripping member 6 is actuated by the piston prior to the movement of its carrier by the piston. The band 34 is passed round an article and through a clip 33 which is then engaged with pusher plate 13 and button 16, Fig. 3, is depressed to admit the pressure fluid to the left-hand side of piston 3, Fig. 1. The initial piston movement acts through a connecting rod 7 to rotate pawl 6 into gripping engagement with band 34 and subsequently the piston engages carrier 4 to apply tension to the band. At the predetermined tension the valve is kept open whilst soldering or clinching the clip. Closing the valve vents the cylinder and springs (18), Fig. 2 (not shown), return the piston 3 and carrier 4 to their original positions. During this movement the abutment surface 37 engages abutment surface 36 to arrest carrier 4 and the continued movement of piston 3 results in anti-clockwise rotation of pawl 6 and consequent release of the band 34. A pressure controlling device and/or a non-return valve and/or a pressure gauge may be included in the supply line from the pressure source e.g. a foot pump.

Title: Data recovery system
IPC: G11B20/14
Filed: 1967-10-25
Abstract: 1,203,437. Data storage. SPERRY RAND CORP. 25 Oct., 1967 [27 Oct., 1966], No. 48453/67. Heading G4C. Apparatus for reading out phase modulated binary data recorded on a magnetic medium includes a gated oscillator having a period substantially half the bit period, a gating circuit, including a reading head, arranged to gate the oscillator on during intervals between alternate transitions to cause it to provide a pulse or a pair of pulses according to the length of the gated interval, and a circuit including switching means arranged to produce an output in response to a pulse occurring in the first half of each bit period, but not to produce any output in response to a pulse occurring in the second half of any bit period. Phase modulated recordings represent a "1" by a transition from a first state to a second and a "0" by a transition from a second state to a first. Thus an extra, non- significant transition is required during a succession of like digits (Fig. 2c). A reading head 11 produces two antiphase outputs 12, 13 which are amplified, differentiated and clipped to produce signals e and -e (Fig. 2). Each signal is fed to a gated oscillator 23, 24. If the input to the oscillator is low then after a fixed delay a pulse of predetermined length is produced and as long as the input is low a succession of pulses of period half the bit period is produced (A, C, Fig. 2). These pulses form one input to AND gates 25, 26 and 28, 29 respectively and also feed trailing edge detectors which in turn are connected to a flip-flop 35. The flip-flop feeds AND gates 25, 26, 28, 29. AND gates 26, 29 feed a further flip-flop 36 which in turn feeds AND gates 25, 28 and NOR gates 45, 46. Initially flip-flops 35, 36 are reset. The first pulse A from gated oscillator 23 enables AND gate 25 to inhibit NOR gate 31 to cause a sprocket waveform G (Fig. 2) which in turn enables NOR gate 45 to produce a "1" pulse. The trailing edge of the pulse operates detector 27 to set flip-flop 35. The second pulse from oscillator 23 sets flip-flop 36. The next pulse comes from oscillator 24 (Fig. 2, C) and creates a pulse from NOR gate 46. The trailing edge of the pulse causes flip-flop 35 to be reset. The second pulse from oscillator 24 resets flip-flop 36. The next pulse comes from oscillator 23 and causes a pulse to be emitted by NOR gate 45. The trailing edge causes flip-flop 35 to be set. The following pulse comes from oscillator 24 but AND gates 28, 29 are inhibited. The trailing edges cause flip-flops 35 to be reset.

If it is desired to move the mast frame to the other end of the frame members, the following steps are carried out: (a) the cylinder 14 is moved to the mid point of the frame members, (b) the cylinder is rotated in a clockwise direction by depressing pedal 17' to raise the end of the piston rod 15 clear of the bracket 16 and (c) the piston is moved in the cylinder so that the piston rod 15' slides along a guide position of the bracket 16' until it is held by the bracket. The mast frame 11 may now be positioned anywhere over a distance extending from the centre to the right hand end of the frame members. In a second embodiment the piston rods are provided with hooks to engage pins mounted on the brackets.

Abstract: 1391532 Transistor pulse circuits GENERAL SIGNAL CORP 23 Oct 1972 [5 Nov 1971] 48672/72 Heading G4H Apparatus for processing time-duration signals (a) containing transient noise portions Tb includes means 18-21 for obtaining a pulse counter representative of the duration of each signal and means 11, 22, to ensure that the transients do not affect the accuracy of the count. Each signal is input (at time To) via a relay 13 and contact 17 to enable clock pulses to pass through a gate 18 to a counter 19, contact bounce being responsible for the transients. The signal passes (T1) via a differentiator 28, 29 to a NOR gate 24 forming part of a monostable circuit 24-27 whose output 31 passes via another differentiator 32, 33 to a second monostable 22 (signals b-f). At time T2 the signal is at level "O" so that a diode 34 conducts to ensure that the positive triggering "spike" of signal f does not reach monostable 22: however, after the second transients (T4) the signal reverts to the "1" level and diode 34 cannot prevent the next positive "spike" from causing circuit 22 to output a latch pulse h to a register 21 and a reset pulse to counter 19. With the above arrangement, the reset and latch pulses are produced only at the end of each signal, and not by each transient. Since the pulses lost during the first transients are to all practical purposes offset by the extra pulses arising from the second ones, the count is effectively the signal length (T0, T3). The time constant of 26, 27 determines the length of the time intervals (T1, T2) and (T3, T4) and is sized to exceed the bounce period adjacent the leading edge of the signal since this is in practice longer than that adjacent the trailing edge.
