Filed: 1932-11-19
Abstract: 389,774. Lathes. SCHAERER, O., 64, Freidengasse, Basle, Switzerland. Nov. 19, 1932, No. 32764. Convention date, Nov. 30, 1931. [Class 83 (iii).] Relates to vertical multispindle lathes of the kind described in Specification 367,722, in which the spindles are rotated on their axes and also partake in the movement of the turret, and in which the work-pieces are fed by gravity when released automatically from the spindle collets ; and consists in the provision of a work-piece feed stop which receives the workpiece in its upper position and descends with it through its feed stroke. The feed stop 163 is mounted in a carrier 162 guided for vertical movement in a housing 162a, and is adapted to be projected into the path of the work-piece m by means of a rack 164 and pinion 165. The pinion 165 is actuated from a cam 169 on a vertical shaft 55 which is driven by a shaft 12 through gearing 56, 57, the shaft 12 being driven from the main shaft of the machine as described in Specification 367,722. The shaft 55 carries a lifting-cam 58 which actuates a sleeve 68 on the spindle 10 to procure release of the work-holding collet, and a second lifting-cam 58a actuates a lever 160 which is linked to the carrier 162 by an adjustable rod 161. In operation, when a spindle reaches the work-feeding station, the feed stop 163, which at this time is in its highest position, is moved in, Fig. 2, to support the work-piece m. The cam 58 then operates to cause release of the work-piece, and the cam 58a lowers the feed stop. When the collet has again gripped the work-piece, the stop is withdrawn and returned to its upper position. If the machine has a plurality of work-feed stations, the shaft 55 drives similar shafts at the other stations by means of a chain 172. The length of the feed stroke is varied by changing the cam 58a, or by varying the position of the pivot of the lever 160 in the slot 63.

Abstract: 1,210,349. Masted lift trucks. JUNGHEINRICH UNTERNCHMENSVERWALTUNG K.G. 1 July, 1969 [16 Aug., 1968], No. 33253/69. Heading B8H. A stacker truck comprising a multiple telescopic mast, operated by cables and an hydraulic ram, and a laterally movable cross-slide 12, Fig. 1, which carries forks 15, 16, has a height indicating device 7 for the forks, adjacent the operator's station. The cross-slide is operated electro-hydraulically, power being supplied through a cable wound on a spring-drum 18. The truck runs on rails and is guided by rollers with vertical axles. A sensing roller 55 cooperates with cams 57 to stop the truck at a preselected point. The forks are pivoted about a vertical axis 14, Fig. 3, by a ram and a link 17. Instead of being guided by rails the truck may be steered and braked by the operator. Fig. 5 shows the height indicator in which a fixed chain 44 rotates sprockets 46, 48 as a carriage 45 supporting the sprockets moves up and down with the forks. This rotation is transmitted to the indicator by a chain 49, a sprocket 50, and a drive-shaft connected to a counter. Circuits are provided to compare the counter output with a preset height device to arrest the forks at a particular selected height. The truck may be programmed to stop at a preselected point and for the forks to move to a preselected height, the cross movements and rotation thereof also being automatic. Interlocks limit the speed of travel of the truck when the forks are raised above a certain height. In a second embodiment, Fig. 10, the forks face sideways and are slidable laterally on guides 10. A television camera may be mounted on the lift platform.

Title: Radiation-sensitive switching circuits
IPC: H03K17/795
Filed: 1973-07-12
Abstract: 1481512 Ignition systems LUCAS ELECTRICAL Ltd 21 June 1974 [12 July 1973 25 Sept 1973] 33333/73 and 44771/73 Heading F1B [Also in Division G1] A control member exposes a radiation detector to a source of radiation at predetermined instants of time, the peak output of the detector is sensed and a trigger circuit operated when the detector output falls to a pre-set proportion of the peak output. The apparatus has application in spark ignition control of an internal combustion engine, or fuel injection control, when the control member is rotated by the engine. In the Fig. 1 circuit, the light from diode 25 is cut off from phototransistor 27 when a spark is required. Under illumination however, the detector is used to charge capacitor 48 to the peak output of transistor 28. A proportion, e.g. 90%, of this obtained across resistor 47 is applied to the base of transistor 53, the base of transistor 51 being supplied with the full value signal. The result is for transistor 54 to conduct more heavily than 52, which saturates, causing 57 to be off, Darlington pair 59, 60 to be on and the winding 61 to conduct. When the phototransistor 27 is cut off, the potential at the base of 51 falls beneath that at 53, maintained by capacitor 48, and transistor 52 conducts increasingly to come out of saturation and turn transistor 57 on, switch off 59, 60, remove current through the coil 61 and thus produce a spark. Changes in the efficiency of the LED or phototransistor are compensated for by feedback of the peak voltage across capacitor 48 to transistor circuit 21-24, controlling current supply to source 25. A modified arrangement, Fig. 2, provides a temperature-stable voltage reference circuit 101- 108 for the light source supply control circuit. Diode 110 permits a wider range of control. The detector circuit is modified to facilitate integration. Transistors 112, 115 act as emitter followers. To modify the circuits of Fig. 1 and 2 to produce a spark on illumination instead of obscuration of the detector, the circuit for transistor 57 is modified as in Fig. 3.

Abstract: 1526630 Valves SHOKETSU KINZOKU KOGYO KK 9 Aug 1977 [26 Aug 1976] 33408/77 Heading F2V A solenoid pilot operated spool valve comprises a spool 27 having an axial passageway 35a in communication with the valve inlet port 21, a piston 31a slidably mounted on the end of the spool and having an axial passage which communicates at one end with the passage 35a and terminates at the other end in a valve seat 32a; activation of a solenoid 37a moves a pilot valve plunger 38a to close a drain 43a and to free the valve seat 32a in the piston 31a so as to permit build-up of pressure in the chamber 30a behind the piston which in turn causes the piston and the spool 27 to move to the left as shown in Fig. 3. De-energization of the solenoid 37a relieves the pressure in the chamber 30a so that the piston returns to the illustrated position. The return movement of the spool is effected by a spring (Figs. 6, 7, not shown) or by a second solenoid pilot valve and piston positioned at the other end of the spool.

Abstract: 1,012,790. Automatic control systems for electrolytic cells. SWISS ALUMINIUM Ltd. Aug 17, 1964 [Aug 30, 1963], No. 33525/64. Drawings to Specification. Heading G3R. The terminal voltage of an electrolytic cell is automatically regulated by a control system which is responsive to cell conditions for a short interval, e.g. one minute, of each of a number of successive electrolysis periods of from five to thirty minutes; during each such interval, regulating data is transmitted as required in response to terminal voltages above the desired value but below a threshold level. During the non-regulated part of each electrolysis period the terminal voltage tends to rise, and with the development of the "anode effect" this voltage, at the start of a regulating interval, tends to exceed the threshold level; the control system is then arranged to effect only limited regulation, so that the terminal voltage rises to an upper limiting value above which the system ceases to transmit regulating data. This arrangement allows for the full development of the "anode effect", said to be necessary for the purpose of regenerating the electrolyte. The operation of the system is described graphically with reference to Fig. 1 (not shown), and apparatus which regulates the terminal voltage by adjusting the distance between the electrodes is describedwith reference to Fig. 2 (not shown) which illustrates schematically a suitable arrangement of known control elements. Specification 602,876 is referred to.

Abstract: 621,564. Carpet sweepers. HEFTLER, P. Dec. 15, 1945, No. 34036. [Class 138(i)] A sweeper for carpets, floors and the like, having wheels, a rotary brush and a handle, the wheels and brush being free to move vertically relative to each other, comprises mechanism for applying the weight of the sweeper partly to the wheels and partly to the brush, and mechanism for applying any pressure from the handle partly to the wheel and partly to the brush in whatever positions relative to each other the wheels and brush take up. The case 8 is of wood and carries on either side of the brush 17 conventional dustpans. Two pairs of floor wheels 21 are carried on arms 9 pivoted to the sheet metal end plates 6 of a frame separate from and movable vertically with respect to the case, being carried on rods 7 passing through tubes extending through the case. The wheels are thus pressed into driving engagement with pulleys 13 on the brush carriers 14 by means of springs 16 slidable in vertical recesses in the end plates 22 of the case, whereby the brush assembly is vertically movable with respect to the wheels and the case. The weight of the case and associated parts is transmitted through brackets 19, partly through gear pivots 18 to the frame, and thence the wheels, and partly through gear teeth to the carrier 14, and thence the brush, whereby the weight is divided by a constant ratio, for example. 5 to 1, between wheels and brush. The handle is pivoted to a carrier 3 slidable vertically on the plate 6 and pressure applied through the handle is transmitted to dividing gears 4, and thence to the wheels through pivots 5 and the frame. and to the brush through gear teeth and the carrier 14, whereby the pressure is divided between the wheels and brush in a ratio which is constant, for example, 17  to 10, but preferably differs from the weight-dividing ratio, so that the brush takes a greater percentage of handle pressure than of weight. The ratios are arranged so that the least possible amount of any applied pressure is applied to the wheels to prevent slipping, the rest being applied to the brush to give maximum sweeping power.
