Title: Improvements in brake operating mechanism for use on motor vehicles
IPC: B60T11/04
Filed: 1924-08-09
Abstract: 236,061. Standard Motor Co., Ltd., and Maudslay, R. W. Aug. 9, 1924. Blocks acting on drums; compensating for wear; force-transmitting mechanism.-To give increased leverage or pressure in applying brakes on motor vehicles the brake actuating arm of each brake or an arm intermediate between the brakes and the operating pedal or equivalent carries a lever, or pulley and the pull of the actuating rod or cable is transmitted by way of the lever or pulley back to an adjusted point on the vehicle frame. As shown in Fig. 3, the cable 3 extends from an adjusting device 17 mounted preferably close to the driver's seat around pulleys 4 carried by the actuating arms 16 of the brakes 2, around a pulley 15 on the pedal 5 to a fixed or adjustable point 13. The pull applied to each arm 16 is thus doubled and is equalized as between the two brakes. In a modification a cable extends from the pedal around a pulley on the arm of only one brake back two an adjustable point on the vehicle frame. Fig. 2 shows a pull rod 11 extending from the pedal 5 to a lever 10 pivoted upon the brake arm 1, and a second rod 12 extending from the lever to the adjusting device 8. The lever or pulley may instead of being mounted upon the arm 1, be carried by arms intermediate of the pedal or equivalent and the brakes.

Title: Improvements in drinking troughs
IPC: A01K7/04
Filed: 1919-07-31
Abstract: 153,638. John, A. E. July 31, 1919. Drinking-appliances for animals.-A drinking- trough 1 for animals is constructed with inlet and outlet channels 6, 9 or pipes running longitudinally of the trough at opposite sides, a float 15 and valve mechanism 11 being fitted within the inlet channel to maintain the level of the water, and the sides of the trough being turned inwardly to form shields 24 over the channels. The weir 3 separating the inlet channel is notched so that as the water-level falls in the trough the float 15 descends and opens a relief valve 13, Fig. 2. This allows the disk valve 18 to open under and release the supply pressure above the valve 12, which thereupon rises and opens the main supply passage. The pressure is equalized on both sides of the valve 18 by a passage 20 or perforation in the valve. Instead of a flexible membrane, this valve may be formed as a disk loosely fitting its casing and having a washer secured to its under surface. Specification 145,133, [Class 135, Valves &c.], is referred to in the Provisional Specification.

IPC: B24B7/24
Filed: 1919-07-31
Abstract: 154,661. Pilkington Bros., and Waldron, F. B. July 31, 1919. Flat extending surfaces, surfacing and polishing.-Plates of glass are mounted for grinding and polishing on rectangular tables adapted to be passed in a series, with their adjacent ends in contact, beneath sets of runners each supplied with a particular grade of abrasive, and means are provided whereby each table, as it passes the last set of runners, may be removed, and another table may be added to the series. The tables 1 are supported and guided by a bed 2 and are moved therealong by worm-driven rack-and-pinion gearing 11, 12 or by a chain, the glass plates passing under sets of runners 3 in succession; the tables may be connected together at their adjacent ends by lugs 15 and cotters, or may contact with each other without being connected. As a table emerges from the last set of runners, it passes on to a trolley 17; the glass is turned over, in order that its other surface may be ground &c. and the trolley is brought to the other end of the bed at 18 and the table is placed in contact with the first table and again passed through the machine. The runners are supported on vertical shafts, mounted in bearings carried by frames 5, 6, and driven by means of pulleys 9. Each set of runners is supplied with one grade of abrasive only and the abrasive is washed off the glass as this passes from one set of runners to the next set, the sets being spaced sufficiently far apart to allow this and also to prevent admixture of grades by centrifugal force. The Provisional Specification describes also apparatus in which the tables are moved by a conveyer, which returns from the finishing end of the apparatus to the starting-end after a table has been detached,

Title: Improvements in or relating to protective arrangements for transistors
IPC: G05F1/569
Filed: 1960-05-30
Abstract: 928,297. Protective arrangements. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 30, 1960 [June 2, 1959], No. 19044/60. Class 38 (5). [Also in Groups XXXV and XL (c)] A circuit arrangement for protecting a transistor from voltage overload comprises a further transistor and a Zener diode so arranged that when the voltage applied to the first transistor exceeds the breakdown voltage of the Zener diode, the further transistor conducts to energize a self-holding relay which reduces the voltage applied to the first transistor. In the embodiments illustrated the transistor 1 constitutes the series element of a voltage stabilizing circuit provided with feed-back through direct-coupled amplifier 6. In Fig. 2, when the voltage across transistor 1 is such as to cause breakdown of Zener diode 2, current flows out of the base of transistor 7 which accordingly is rendered conductive to energize relay 10. Contact 13 closes to cause the relay to hold and contact 12 opens to disconnect the series circuit through transistor 1 with the exception of that through resistor 9, the basecollector diode of transistor 7, contact 13 and resistor 14. In Fig. 3, Zener diode 2 is normally conductive. When the voltage across transistor 1 exceeds that established across the Zener diode, transistor 7 conducts to energize relay 10 so causing contacts 15 to change over to energize a holding winding on the relay and disconnect the transistor 1.

Title: A circuit arrangement for measuring parameters of networks or devices
Inventor: BUHN UWE
IPC: G01R27/28
Filed: 1964-05-07
Abstract: 1, 057, 896. Measuring parameters of four terminal networks. FUNKWERKE DRESDEN VEB. May 7, 1964, No. 19060/64. Heading G1U. An arrangement for measuring any four matrixrelated parameters, such as admittance, impedance or hybrid parameters, of a four terminal network, in terms of real and imaginary parts, comprises two arrangements adapted to measure the appropriate input or output parameters, one connected to the input and the other to the output of the four terminal network. One arrangement is adapted to carry out an input parameter measurement and also to couple energy into the network, while the other is arranged so that it provides signals which balance the output from the network, so that a transfer parameter may be measured. The functions of the two arrangements are interchangeable so that all of the relevant matrix related parameters may be measured. The four terminal network may be, for example, a transistor. The four terminal network 1 is connected by coaxial lines 11 and 12 to junction points 4 and 5. The lengths of the lines 11 and 12 are chosen to provide suitable matching. At the junction points are connected further matched lines 13, 15 and 14, 16 respectively. These are terminated by resistors 8À1, 9À1 and by reactances 6À1, 7À1 as shown. The junction points are also connected to a two pole switch 10, which is arranged so that as one junction point is connected to a meter 3, the other point is earthed. Energy from a source 2 may be coupled into all of the lines 11-16 through the variable coupling arrangements 4À1, 4À2, 4À3 and 5À1, 5À2, 5À3, the line lengths from the source to these arrangements being such that the energy reaches the coupling arrangements with the same amplitude and phase. A typical set of parameters undergoing measurement may be the admittance parameters, given by: where i 1 , v 1 , i 2 , v 2  refer to input and output currents and voltages of the four terminal network. In order to measure the input parameters Y 11 , Y 21  considering the line 12 as the input, the coupling arrangement 5À1 is adjusted so that no energy is coupled into the line 11 and the loops 4À1, 4À2, 4.3 are set so that the indicator 3, which is connected to the junction 4, shows zero voltage at the point 4. The positions of the loops 4À1, 4À2, 4.3 give a measure of Y 11 , the junction 5 being short circuited. If the switch 10 is now changed so that the point 4 is short circuited and the indicator is connected to the point 5, the arrangements 4À1, 5À2 and 5À3 may be adjusted to determine the transfer parameter Y 21  (5À1 still being adjusted so that no energy is coupled in to the line 11). The procedure is then altered so that the junctions 4 and 5 are effectively interchanged to determine the parameters Y 22  and Y 12 . The reactances 6, 7 and the resistances 8, 9 may be adjusted so that the ranges over which measurements may be made can be adjusted.

Abstract: 718,407. Filling bags, sacks, &c. HOELLER, W., HOELLER, F., [trading as HOELLER MASCHINENFABRIK, GEB.]. July 31, 1952, [Nov. 14, 1951.] No. 19360/52. Class 94 (1). A machine for automatically filling sacks, bags, &c., 36 fed from a stack 16 comprises four openended chambers 4.... 7 at right angles to each other rotatable about a suction pipe 2 closed at the top and having two openings 8, 9 opposite adjacent chambers 4, 5, the chambers having arranged around their open fronts, in the direction of rotation, a container 15 for the stack of bags, &c., from which a bag is picked off by suction within the chamber, a pneumatic opening device 17, 18, a filling device 23 and a conveyer 26 for removing the filled bags. The stack container 15 is moved to a position in front of the chamber 4 and a flap 12 opened to subject this chamber to vacuum so that a bag is extracted from the stack and held in front of the open chamber by the suction. The chambers are now rotated through go degrees about the vertical suction pipe 2, the flap 12 2 closed by a pin 14 operated by a cam 60 and the bag is brought opposite a suction pipe 19 which opens the top of the bag. A hook 30 moves down to support the bag, suction being cut off from the chamber, and the bag is blown open by pressure air supplied by a mouthpiece 18 swung into the bag. A finger opens up the folded bottom of the bag so that it is opened to its full length by the compressed air. A further rotation through go degrees 'brings the open bag below the pipe 23 of a filling device 22 and opposite a suction pipe 24 and a spreading finger 25 which hold it open during filling. The chambers are then again turned through go degrees and the hook 30 raised so that the filled bag drops on to the conveyer belt 26. A blower produces both the suction and pressure which are controlled by valves in the required sequence. The hooks 30 on opposite chambers are connected together for alternate operation by rods 34.

Abstract: 835,022. Photo-electric control systems. RANK CINTEL Ltd. June 21, 1957 [June 22, 1956], No. 19383/56. Class 40 (3). [Also in Group XXXV] In a system for controlling the traversal of a scanning element over a scanned area, comprising an arrangement for traversing the element or other elements subjected to geometrically similar movements over a pair of arrays of alternate parallel strips, the strips of which are differently inclined to the direction of scanning whereby a pair of signals each having a repetition rate and phase determined by the traversal of the element are produced, means are provided for comparing one of the signals with a further signal to maintain a desired velocity of scan and for comparing the phase of the pair of signals to ensure that the element scans the area along a desired line. The beam from the cathode-ray tube 1 which is desired to scan the area 2 in a predetermined manner at a predetermined velocity is applied also by a beam splitter 8 comprising a pair of part silvered mirrors to fields 11, 12 of alternate opaque and transparent strips to produce square-wave output signals from photoelectric cells 13, 14 the widths of the opaque and transparent strips of fields 11 being equal and the widths of the inclined strips of the field 12 being such as to produce an identical waveform. The square-wave output from photocell 13 is compared in frequency with a reference voltage of accurate frequency applied to terminal 17 to produce an error voltage for application to scanning generator 5 which maintains the desired speed of scan. The outputs of both photo-cells 13, 14 after amplification are compared as regards phase in a comparator 19 to produce a vertical error signal for application to scanning generator 6 whereby the desired position of the line of scan is achieved. An arrangement for separating the signals from two fields of lines equally inclined to the desired line of scan is described with reference to Fig. 7 (not shown). A counter 21 actuated by the scanning generator 5 is applied to control the insertion of a tapped delay line or other phase-shifting circuit where multiline scanning is desired. The signal applied at terminals 17 may be such as to cause the speed of scan to vary in a predetermined manner. The application of the invention to circular and spiral scans and to systems using the cathode-ray flying spot, and electron beam scanning is referred to. Auxiliary electron beams may scan strip patterns of differing secondary emissivity or the main electron beam might pass through an electron system before reaching its target. Specification 641,936 is referred to.

Title: Improvements in or relating to ammonium nitrate blasting cartridges
IPC: F42B3/00
Filed: 1947-07-21
Abstract: 643,871. Blasting cartridges; explosive compositions. ATLAS POWDER CO. July 21, 1947, No. 19450. Convention date, Nov. 16, 1943. [Classes 9 (i) and 9 (ii)] A blasting cartridge for use underwater comprises a waterpervious case 11 filled with a water-absorptive ammoniun nitrate explosive composition 13 which includes a sensitizer and having a waterproof high explosive core 17. The case 11 is of paper crimped over at the ends and the ammonium nitrate is sensitized with nitroglycerine. The high explosive core 17 is a paper-wrappec charge of gelatinized nitroglycerine dynamite. The core may extend only part-way through the cartridge and its diameter may be varied to alter the longitudinal velocity of detonation of the cartridge. This velocity may also be varied by using different types of dynamite for the core, such as ordinary nitro-glycerine dynamite in a water-proof container or electro-plated TNT. The cross-sectional area of the core is between 3 per cent and 15 per cent of that of the cartridge. Sensitizers of ammonium nitrate given are nitro compounds, such as dinitrotoluene, trinitrotoluene, cyclonite, nitric esters, such as nitro-glycerine, nitro-glycol and nitro-sugars, and metal powders, such as aluminium dust. The amount of sensitizer in the ammonium nitrate may be between 4 per cent and 20 per cent by weight of the nitrate. To initiate the cartridge when wet a detonator or detonating fuze may be inserted into the core or a quantity of gelatine dynamite containing a detonator may be placed in the bore-hole adjacent the core. Preferably water present in the ammonium nitrate exceeds 6 per cent of its weight. The water may be poured into the borehole after the cartridge is placed in position. In an example, paper cases of 6 in. diameter were filled with ammonium nitrate explosive around a 1 in. diameter core. The cartridge was 24 in. long and weighed 25 lb. The ammonium nitrate explosive consisted of ammonium nitrate 81 per cent, nitroglycerine 6 per cent, sulphur 4¢ per cent, sodium nitrate ¢ per cent, chalk per cent, carbonaceous ingredients 7¢ per cent, all percentages being by weight. The cartridge was initiated underwater by firing an electric blasting cap placed in gelatine dynamite against the cartridge. An alternative cartridge contained 44.8 per cent ammonium nitrate and the sulphur was omitted.
