Abstract: 915,168. Strap fastenings. HARLEY PATENTS (INTERNATIONAL) Ltd., and HARLEY, F. B. July 3, 1961 [July 8, 1960], No. 23993/60. Class 44. A releasable connector comprises a cup 20 having apertures 50 to receive plates attached to the shoulder and lap straps of a safety harness, the plates being formed with holes 16 engageable with spring-urged bolts 52 which project through apertures in a disc 25 slidably mounted in the cup. The disc carries a post 29 formed with cam surfaces 30 and coaxial with a tube 35 provided with a transverse pin 39, the projecting ends of which act as camfollowers. An actuating knob 40 is secured to the tube 35 and has a central boss 45 having a cut 47 to receive the ends of the pin 39 so that rotation of the knob turns the pin and tube, the pin riding over the surfaces 30 to lower the post 29 and hence the disc 25. The bolts 52 are thus forced downwardly clear of the holes 16 so that the plates may be withdrawn from the connector, the bolt 60 still engaging the plate 11 so that the connector is permanently secured to a lap strap. A release member 70 is pivoted in an aperture in the actuating knob and has two projections 74 extending through a slot 75 and overlying the bolts 52 corresponding to the shoulder straps so that when the member 70 is depressed the projections force down these bolts so that the shoulder straps may be released from the connector. Specification 895,482 is referred to.

Abstract: 1292761 Regulating IC engine SOC FINANCIERE ET INDUSTRIELLE DES ATELIERS ET CHANTIERS DE BRETAGNE 11 Jan 1971 [5 Feb 1970] 1180/71 Heading F1B [Also in Division G3] In a diesel engine having a separate electrically operated injector for each cylinder a controller responsive at least to the actual engine speed and a reference speed opens the injectors for as long as is necessary in each operating cycle to maintain the actual speed equal to the reference. The reference speed signal derived from a potentiometer 32 and the actual speed signal from the rectified output of an A. C. tachogenerator 33 are connected to a P.I.D. controller 29 (not described). The injectors are arranged and controlled in two groups, with a control channel a and b for each group respectively. A proximity detector 39 produces a signal when each pistion is 15 degrees before top dead centre. The signals are distributed at 37 to respective "advance-delay" devices 36a, 36b which in response to the engine speed signal determines the angle of advance at which each injector is to open. The outputs of devices 36 pass through further devices 34 and are amplified at 35 and distributed at 26 to initiate energisation of the injectors. The devices 34, in response to the output of controller 29, determine the duration of the injection energisation and hence the amount of fuel injected at each stroke. The "advance delay" devices 36 comprise analogue circuits Fig. 4 (not shown) in which constants from potentiometers are combined with the speed signal and the result compared with a ramp waveform started by the proximity detector. The output signal is produced when the comparison shows equality. Fig. 1 shows an injector. When coil 22 is energized the tappet 15 is raised against the tension in spring 16 so allowing the pressure of fuel from a common pump to raise needle 15 and uncover outlet orifice 5. The invention is used on marine or stationary diesel engines.

Title: Improvements in and relating to machines for forming plastic material
IPC: C03B17/04
Filed: 1926-01-15
Abstract: 246,157. British Thomson-Houston Co., Ltd., (Assignees of Miller, L. B.). Jan. 19, 1925, [Convention date]. Fused silica. - A device for forming plastic material, particularly fused silica, into lengths comprises a piston for extruding the material through a die or opening, and means for applying pressure to the piston to overcome the resistance offered by the material, the pressure applied to the piston being varied automatically according to the resistance offered by the material. Thesilica is fused in a crucible 3 in an electric furnace, as described in Specification 189,926, and it is extruded through a die 4 into a length 5. The pressure for extrusion is applied by means of a piston 6, an additional weight 8 being applied to the rod 7 of the piston if the weight of the piston is not sufficient. In order that the extruded length 5 may be of practically constant diameter, it is necessary that the rate of flow should be constant, and to ensure this, means are provided for varying the pressure on the piston. For this purpose, the weight 8 is connected by a cable 10 with a balance weight 9, and a motor 13 is provided to drive a winding-drum 20 which raises the weight 9 at a determined rate of speed. With this device the weight 8 cannot descend at a greater rate than that at which the balance weight 9 is raised, and too great a rate of extrusion of the silica is prevented. If the silica becomes too viscous, the piston 6 is retarded, but the raising of the weight 9 allows the full force of the weight 8 to be applied to the piston. The cable 10 passes between pulleys 24, 25 carried by a pivoted frame 23, and when the cable is taut, the frame is held in the position shown. If the piston 6 is stopped by any means, the cable 10 slackens and the frame 23 is tilted by a weight 27. The movement of the frame opens a switch 28, 29 which stops the motor 13 and prevents excessive sagging of the cable 10.

Filed: 1955-01-14
Abstract: 796,287. Guillotine cutting machines. SOAG MACHINE TOOLS, Ltd. Jan. 13, 1956 [Jan. 14, 1955], No. 1277/55. Class 31 (1). A guillotine cutting machine is provided with automatic spacing mechanism for causing the back gauge to move the work through a predetermined distance and to reset itself in readiness to advance the work through the same predetermined distance whereby repetitive cuts can be made in the work. As shown, the back gauge 2 has a nut 4 engaged by a screw 5 driven by gearing 6 from an electric motor 7. The back gauge has connected to it a chain 11<SP>1</SP> or like flexible member which passes over chain wheels 11, 12. The automatic spacing mechanism, Fig. 5, incorporates four control units, each comprising a slide 14 movable in fixed guides 15 and connected by a cable 16 to a pulley 17 which is connected to the chain wheel 12 by means of an electromagnetic clutch. Thus, when the back gauge is moved by the motor 7, the pulley 17 is turned and the slide 14 raised in synchronism with the movement of the back gauge. The slide 14 carries a member 18 adapted to operate a lever 19 which is arranged to actuate a microswitch 19<SP>1</SP> to open the circuit to the motor 7. This switch also disengages the electromagnetic clutch to free the pulley 17 so that the slide 14 falls to its original position in readiness for a repeat operation. The clutch is re-engaged when a push-button is operated to re-energize the motor 7 after a cutting operation has been completed, whereupon the operation is repeated. The switch 19<SP>1</SP> and its lever 19 are carried by a slide 20 which can be adjusted against a scale 21 so as to give different widths of strip between cutting operations. To effect control of the back gauge so that it has a fast speed and a slow speed, the slide is provided with a second lever 22, Fig. 6, controlling a second microswitch 22<SP>1</SP>; one of the switches 191, 22<SP>1</SP> is used to set the motor at a crawl speed and the other to stop the motor. The switch or switches 19<SP>1</SP>, 22<SP>1</SP> and associated lever or levers 19, 22 are carried by a plate 23 supported from the slide 20 so that it can be given a fine adjustment by a screw and nut device 24. In a modification, Fig. 8 (not shown), eight control units are provided. There may, however, be only a single control unit. In another modification, Fig. 9 (not shown), the slide is arranged, in the event of switch failure, to operate a lever to actuate a safety switch to open the whole control circuit. When a plurality of control units are provided a control unit may be brought into use selectively by means of a rotary switch. The machine may also be equipped with a known kind of spacing mechanism using a control bar having stops to control the circuit of the motor 7.

Abstract: 493,252. Spray carburetters. ETABLISSEMENTS G. CLESSE. Jan. 17, 1938, No. 1474. Convention date, Jan. 21, 1937. [Class 7 (iii)] In a downdraught carburetter having a pressure regulator of the diaphragm type in the feed pipe leading to the fuel nozzle, the diaphragm is subjected to the action of a spring and the load of the spring is increased as the throttle is opened. In the carburetter shown, fuel is fed under pressure past a valve 24 to a nozzle 14 and is controlled by a diaphragm 21 connected to the valve. As the throttle valve 4 is opened a cam 43 rotates levers 42, 40 and permits a spring 32 to lower a piston 31 to increase the pressure of a spring 30 loading the diaphragm 21, until an adjustable screw 39 in the piston-rod 35 contacts with the lever 40. The nozzle 14 discharges into a tube 13 containing a Venturi 17 opening to the air inlet 2 and lateral ports 16 through which the mixture is discharged. During slow running, mixture is drawn through a notch and an orifice 6 in the throttle. The connection between the throttle and the spring means may be a lever and links. To obtain a richer mixture at starting, the throttle is opened slightly and the piston-rod 35 is depressed by a pivoted lever.

Filed: 1970-01-13
Abstract: 1,271,601. Measuring thin films. INTERNATIONAL BUSINESS MACHINES CORP. 13 Jan., 1970 [15 Jan., 1969], No. 1529/70. Heading G4H. [Also in Division G1] The thickness of a thin transparent film 22 is measured by investigating light reflected from the top and bottom surfaces of the film 22, which light interferes to give maximum and minimum intensities across the plane of a photodetector 32, while the angle of incidence of the light on the film is varied by rotation of the film support 24. The angle of rotation is monitored and displayed on an indicator at least when a maximum or a minimum intensity is detected. In Fig. 1, an incandescent source 10 and a filter 30 are used to provide monochromatic light for detection, but alternatively a laser source may be used. Also in the light path are slits 12, 14 or a lens-type collemator, a polarizer 17, semi-reflecting mirror 18 and mirror 20 which is rotated with the film about axis 44. In the Fig. 1 arrangement, a cosine potentiometer is varied in accordance with the angle of rotation of motor-driven shaft 48. The potentiometer is in an analogue circuit also including a capacitor (or inductor) and a resistor detailed in Figs. 3 and 5 (not shown), the circuit values being chosen and the circuit being previously calibrated, using a known film, so that its output is dependent on the film thickness. When a minimum intensity is incident on the detector 32 (a photomultiplier), a peak detector triggers the digital voltmeter 40 so that it can display the thickness value. In alternative arrangements, the shaft angle is encoded digitally and the voltmeter 40 fed via an A/D converter, Fig. 1A; a linear potentiometer and the photomultiplier feed a chart recorder; a sine potentiometer replaces the cosine potentiometer. The peak detector circuit is illustrated, Fig. 4 (not shown), and may alternatively comprise a differentiator.
