Heading H3T. [Also in Division H1] A switching circuit comprises a magnetoresistor 3 located in the field of a control coil 2 and connected across the input of an emitter follower 5 feeding a common emitter stage 6, the magneto-resistor being connected to the collector supply via a resistor 4, which may be variable. The coil may be provided with a core and premagnetized such that either an increase or a decrease in control coil current operates the switching circuit. Separate transistors may be controlled by the emitter and collector circuits of transistor 5 so that the collector circuits operate as a changeover switch. The same facility may be provided alternatively by providing separate magneto-resistors above and below the magnetic core, each feeding its own amplifier (Fig. 9, not shown). Multiple switching may be provided by a plurality of magnetoresistors located between respective teeth on the poles of the core or located in the magnetic circuit of a plurality of magnets (Figs. 5-8, not shown). Fig. 10 shows a bi-stable-state circuit triggerable at 28, the stability being obtained by feedback to the coil. If the coil is tuned by a capacitor or varicap diode, the circuit will oscillate (Fig. 11, not shown). Fig. 6 shows the circuit arranged as a contactless relay assembly comprising a printed circuit board carrying the transistors and resistors and having a printed external connection strip 24. The ends of the core are slotted laterally of the Figure to accommodate a plurality of magnetoresistors (Figs. 7 and 8, not shown). Fig. 4 (not shown) illustrates an alternative construction having a single magneto-resistor and having plug-in connectors mounted in a printed circuit base-board. The arrangement may plug in to a conventional relay socket.

Title: Improvements in kinematographic apparatus
IPC: G03B1/22
Filed: 1926-05-25
Abstract: 253,098. Le Blay, P. A. M., and Le Blay, G. June 6, 1925, [Convention date]. Kinematograph apparatus. - Feed claws, slidably mounted on a pivoted carriage which is oscillated by a connecting rod and crank disc, and reciprocated in the carriage by means of the connecting rod, are provided in combination with a spring motor and means for enabling single exposures to be made; reciprocating registering pins, and means for registering the speed of the driving motor may also be provided. As shown, a carriage 9, pivoted at 14, is oscillated by a connecting rod 11 and crank disc 13. Feed claws 8, slidable in a recess in the carriage 9, are provided with a guide 10 which is engaged by the rod 11 to cause the claws to move into and out of the film perforations. Registering pins 16 engage the film perforations during the inoperative movement of the claws 8 and are reciprocated into and out of them by a rod 17 connected to an eccentric 18 on a spindle 19. The spindle 19 also carries pivoted weights m, n, which are connected by a spring. The weights turn, when the speed is excessive, to engage a housing 24 for a disc 23 secured to the end of the spindle 19, and produce a braking action. The mechanism is driven by a spring in a toothed drum 1 engaging pinions 15, 21, and is controlled by a plunger 29 having a stud engaging a sector 34 secured to a pinion 35 driven by the drum 1. The plunger may be arranged so that a stud carried by it enters any of three grooves, and, in accordance with the groove selected, the apparatus operates to produce a kinematographic series of images, a single exposure, or a single opening or closing movement of the shutter.
Patent GB-1528058-A (GB)
Title: Automatic braking force regulators
IPC: B60T8/18
Filed: 1976-04-01
Abstract: 1528058 Load-responsive proportioning valves DAIMLER-BENZ AG 1 April 1976 [3 April 1975] 13195/76 Headings F2F and F2V An automatic brake pressure regulator 8, Fig. 2, varies brake pressure with load, the latter being represented by the variation of the distance between the regulator 8 mounted on the vehicle frame 9, Fig. 1, and the vehicle axles 1 and 2, the regulator including a control lever 6 which rotates in one direction with increasing load and in the opposite direction with decreasing load, the braking pressure being variable between a maximum corresponding to the regulator input pressure at full load and a predetermined minimum at no load, but if the lever 6 or its associated transmission linkage is severed, a spring in the regulator rotates control lever 6 beyond the minimum pressure position to result in a brake pressure above the minimum. In the regulator of Fig. 2, increasing input pressure at 11 causes downward movement of piston 13, eventually causing tappet 15 to lift valve member 14 from its seat to allow communication from inlet 11 to outlet 19 to the brake cylinders. A diaphragm 21 connects housing 22 with piston 13 and is progressively stretched over an entraining disc 24 of piston 13 as the latter moves downwards. When the maximum brake pressure for the particular load has been reached the piston 13 is returned to the initial position shown. The control lever 6 controls the position of the tappet 15 by rotating a cam 17 between a maximum pressure (fully loaded) position II and minimum (no load) position IV, the latter resulting in later opening of valve 14 in the stroke of piston 13 due to the depressed position of tappet 15. If the control lever 6 or its transmission linkage (parts 3, 5 and 7) is severed, a torsion spring (not shown) associated with shaft 27 rotates the shaft and cam, and hence lever 6, beyond position IV to a position V which causes the tappet 15 to rise to a position giving a braking pressure above the minimum and amounting to preferably 65% of the maximum.

Title: Improvements in or relating to means for controlling yarns in knitting machines
IPC: D04B15/58
Filed: 1941-10-16
Abstract: 550,790. Knitting machines. MELLOR, BROMLEY & CO., Ltd., BROMLEY, T. C., and SHORTLAND, A. Oct. 16, 1941, No. 13336. [Class 74 (ii)] A take-up mechanism for separate yarns of differing strengths supplied at a common feeding point in a knitting-machine comprises members 1, 2 coupled together for movement towards and from the needles and capable of limited relative movement. In one form, the members are pivoted together by a pin and slot connection 6, 7 and each is pivoted to a fixed bracket 10. One member 1 is under control of a spring 11. The take-up members can be held inoperative by a catch lever 21 actuated by a push rod 25 under control of the pattern chain or drum. Means for tensioning the yarns between the supply and the take-up members may comprise rods 16, 17 and a spring 18. The rod 17 is fixed to the bracket 10 and the second rod 16 is pivoted at 19 and urged by a spring 20 so that its outer end engages the rod 17. One yarn y is fed between the engaging rods, and the second yarn y<SP>1</SP> is fed between the spring 18 and the rod 17. A projection 16a on the rod is engaged by the take-up member 1 when the take-up mechanism is rendered inoperative so that the tensioning means are also made inoperative. In a modication, the two take-up members are pivoted to rotate about the same fixed pivot, and one member is controlled by a spring in somewhat similar fashion to the control of member 1 by the spring 11. To couple the two members together and to allow for relative movement between them a torsion spring is arranged around the fixed pivot and has its ends secured to the two members. In this form the tensioning means comprise two eccentrics controlled by springs or counterweights so as to grip the yarns against fixed rods and having means for rotating them so that the yarns can run freely when the take-up members are rendered inoperative. In yet another form, the take-up members are mounted upon the same spring-controlled lever ; one member is fixed to the lever and the other member is formed integrally with the torsion spring arranged upon a pin on the lever so that it can move relatively to the other member. The invention is described in connection with a circular seamless hosiery machine and is applicable to plain and rib machines, including the double cylinder type, to stationary cylinder as well as to rotary ' needle cylinder machines, to multifeeder or single feeder machines with latch or bearded needles, and to flat knitting-machines. Specification 550,370 is referred to.
