Abstract: 1,232,391. Slab press control circuit. DAVY & UNITED ENG. CO. Ltd. 18 Sept., 1968 [22 June, 1967], No. 28973/67. Heading B5A. Apparatus for controlling a slab moulding press wherein the slab is compressed between platens by one or more rams acting on at least one of the platens, comprises means settable to the dimension of the slab, a computing circuit for computing the required fluid pressure for the rams from a preset moulding pressure and the slab dimensions which computing circuit produces a signal proportional to this fluid pressure and means responsible to the signal to control the ram fluid pressure at the desired value. An initial circuit may be provided to calculate the number of rams needed according to the dimensions of the slab. As shown, the slab size is set on dials 12, 13 of control desk 14. The control desk calculates the number of rams needed (N) and passes this signal together with signals corresponding to the slab length and width to a computing circuit 18 where the ram pressure is calculated (inputs corresponding to ram area and preset moulding pressure (potentiometer 30) being provided). A signal corresponding to this pressure is fed through amplifier 21 to a relief valve 22 which operates the valves 23 on the rams. A pressure transducer 24 in the fluid feeds back the actual pressure in the rams to amplifier 21 and also provides a signal to a second computing circuit 26 which calculates the pressure on the slab, and shows it on dial 28 and provides visual indication via light 32 and 33 as to whether the pressure is at or below a predetermined minimum permissible pressure set by control 31.

Abstract: 1,237,968. Garage lifts. O. A. SUAREZ. 6 Aug., 1969, No. 39287/69. Heading B8H. An hydraulically operated garage lift, Fig. 2, has tracks 1 with end ramps 2 and wheel guides 3 attached at 5 to horizontally pivoted arms 4, the ends of which move in arcuate guide slots 6. The arms 4, Fig. 20, are pivoted by a rod 64 oppositely threaded at each end. One end of this rod is arranged to move over a scale which indicates the spacing of the guides. Pins which pass through holes 8, Fig. 2, lock the guides in position. The lifting frame 15 is raised by pairs of arms 10 pivoted by rams. The arms and rams may be arranged as shown in Figs. 8-11, (not shown). Struts 25, Fig. 12, hold the arms 10 in their raised position. The bottom of the struts may be pivoted instead of resting on a toothed rack 26. In this case a series of holes are provided in the arms 10. Fig. 15 shows an arrangement in which the struts 25 are automatically engaged in holes 27 by a spring loaded lever 30, 32 pivoted to the lifting ram. To lower the lift the lever is disengaged from the struts 25 by lifting the end 35. As a safety precaution, oil is discharged from the rams through a small orifice which retards the descent of the lifting frame.

Abstract: 1,238,760. Tape handling. FERRANTI Ltd. 22 Dec., 1969 [23 Dec., 1968], No. 62428/69. Heading G5R. [Also in Division G3] The tape or other strip material passing between supply and takeup spools (Fig. 2, not shown) is maintained taut and stored by means of a frame, consisting of posts 24 on spokes 25, which rotates to form a tape path of varying length around a spool. The frame is urged by a coil spring (38, Fig. 6, not shown) in the unwinding direction of the spool; and has cams (54, 56) which operate microswitches (50, 52) which may switch the motor on-off, or change its direction, or alter its speed, according to the angular position of the frame. For rotation of the frame through more than 360 degrees, Fig. 8 (not shown), the cams may be positioned on a separate rotary member (60, Fig. 9) which is coupled to the frame by gearing. Instead of posts on spokes, the frame may be of continuous arcuate form (Fig. 10, not shown).

Abstract: 1,239,423. Pulse thresholding circuit. HOFFMAN ELECTRONICS CORP. 26 June, 1968 [10 July, 1967], No. 30541/68. Headings H3T and H4D. A pulse thresholding circuit, especially for signal to noise ratio improval in pulse data systems, comprises a pulse rate sensing device providing an output voltage proportional to the circuit pulse rate, which voltage is compared with a predetermined finite reference voltage value such that if it exceeds it, the threshold is increased from a predetermined finite lower limit. In Fig. 3, two duplicated systems are used respectively for the AIR/AIR, AIR/GROUND modes of operation, which are selected by means of a pulse to either of the terminals A/A, A/G. This switches on a respective one of the multivibrators 30, 32, each having a setting for determining the required mode frequency of operation. Each system has a differential amplifier 66, 80 which sets the threshold level, having a variable value above a lower limit. If the input frequency is too high because of noise pulses, then the level converter 34, supplied with pulses from a respective multivibrator, has an output voltage sufficient for amplifier 42 to switch on either of transistors 46, 48. These will then control the threshold voltage of a respective amplifier 66, 80, which level is initially set by voltage dividers 60, 62 and 76, 78 respectively, such as to lower the number of pulses passed. The circuit is described in the Specification with respect to the TACAN system.
