Title: Improvements in or relating to Automatic Delayed Action Electric Switches.
Inventor: WOODHOUSE ALBERT ERNEST
IPC: H01H29/10
Filed: 1918-05-04
Abstract: 128,338. Woodhouse, A. E. May 4, 1918. Controllers w i t h auxiliary switches; with mercury contacts.-An automatic delayedaction switch comprises a mercury container b communicating by an adjustable orifice e' with a chamber c containing a float valve m so that, when the switch member is swung through 180 degrees about the contact pivot g into the position shown (where a contact located at the upper end of the switch member and connected with the interior contact j engages with a fixed contact h), the mercury parses into the float chamber, and, after a certain time, raises the float which opens the adjustable orifice f<1> letting the mercury into the terminal chamber d where, after a further time depending on the height of the terminal j, the external circuit is completed. The switch may be used in association with a variable resistance as a motor starter. In the form shown in Fig. 3, the switch member is extended below the terminal chamber to constitute two chambers 5, 6 separated by a partition with an orifice 4. The upper chamber contains resistance material such as carbon granules which, when the switch is set in the position shown to start the motor, gradually fall into the lower chamber and fill up the annular space between the sleeve 7 connected by spring blades 3 to the external contact 2 and the metal casing a similarly connected to the other external contact. The resistance in the motor circuit is thereby gradually lowered and at the same time the mercury is flowing into the float chamber. The float is so set that when the resistance has been sufficiently reduced the float lifts and the mercury connects together the contact 1 and the outer casing, thereby short circuiting the resistance. The combined switch and resistance member is pivoted between its ends and, when swung round to the unset position, the fixed contacts are not engaged.

Title: Improvements in fuel injecting means for internal combustion engines
IPC: F02M61/10
Filed: 1941-06-16
Abstract: 545,559. Fuel injection pumps. AKTIEBOLAGET ATLAS DIESEL. June 16, 1941, No. 7616. Convention date, July 8, 1940. [Class 102 (i)] [Also in Group XXVII] A fuel-injection valve 11 is opened against the action of a spring 22 by the pressure of fuel supplied by a pump 2 acting on differential pistons 12, 14 in separate chambers 13, 15, the former of which communicates through the injection valve with the cylinder, and through a valve 6 with the pump. The chamber 15 is directly connected to the pump chamber 18 by a' pipe 20, so that when the pump, on its return stroke, opens ports 3, the pressure on the piston 14 is relieved. The spring 5 of the valve 6 may be dimensioned so that the valve opens at a higher pressure than the injection valve 11, a pilot injection being effected through the expansion of the fuel as soon as the valve 11 opens, and the main injection occurring when the valve 6 opens. In a modification a return valve is provided in the pump in the passage leading to the chamber 13, so that a reduction of pressure takes place in this chamber on the return stroke of the pump ; or both the valve 6 and the return valve may be arranged in the injection valve casing. Further, the piston 14 may be made separate from the piston 12, and the valve 6 may be a pressure-reducing valve. Fig. 6 shows a combined fuel pump 2 and injection valve 11, a pressure-reducing valve 36 being arranged between the pump chamber 18 and the chamber 13. The piston 12 is connected to the piston 14 by a lead 41 entering a radial slot 39. In another form, the larger piston may act on the upper end of the spring 22 of the injection. valve. Also the injection valve may itself act as the smaller piston after it has opened, and in this case it may have an enlarged lead opening into the cylinder. The pump cam 42 may be shaped as shown to give a more pronounced rise to the punger at the middle of the stroke than at the beginning and the end.

Abstract: 806,853. Drilling-machine details. SERCK RADIATORS Ltd. March 11, 1957 [March 14, 1956], No. 7945/56. Class 83 (3). In a multi-spindle drilling- machine having a work-table, a laterally-movable headstock on a guide supported by pillars, and a number of drillspindles mounted vertically on said headstocks, the drillspindles are selectively engageable with fluid-pressureoperated feed - mechanism. Bearings 12 carrying the drillspindles 13, are laterallyadjustable on guide-bars 14 mounted on the headstock 9, by pinions 15, meshing with rack-teeth on the bars. Upper and lower shafts 40, driven by a motor 41, respectively transmit rotation to alternate drill - spindles 13 through helical gears 42, 43. Each spindle 13 is held by a bearing 19 in a head 20, and can be displaced vertically by connecting the head by a latch 21 to a member 18 operated by fluid-pressure means 16, 17. A piston-rod 27 of a cylinder 25 mounted on each bearing 12, carries a tappet 28 engageable with contacts 29 which electrically control the pressure to the cylinder 25. In operation, each latch 21 is normally pressed by a spring 38 into a recess 23 of its bearing 12, but for drilling a predetermined pattern of holes in a row, selected latches are moved by their pistons 27, which engage yokes 30 on the latches, into engagement with recesses 22 in member 18, whereupon energization of cylinder 16 feeds the selected spindles to the work. During feed, the operative latches 21 are locked by spring-detents 31 engaging notches 33 therein. At the end of the return stroke of the piston 17 and spindles, detents 31 engage stops 34 to release the latches 21 for return to recesses 23 by springs 38, the yokes also returning pistons 27 to starting position. The valves for cylinders 16, 25 may be controlled by punched cards or tape, which may also control a motor 11 to traverse the headstock 9 laterally, through a screw 10, between successive drilling operations, to drill additional similarly or differently-spaced holes in a row, and may also control a motor for traversing the work-table for drilling additional rows of holes. The punched cards &c. may operate through electronic, photo-electric, &c. means.

Abstract: 872,457. Coated fabrics. SMITH & NEPHEW Ltd., T. J. March 13, 1959 [March 13, 1958], No. 8092/58. Class 140. [Also in Group VI] A decorative human rail coating comprises a thin sheet or film of pliable flexible plastic material which includes a desired colouring matter in its composition, coated on one surface with a layer of a waterproof pressure-sensitive adhesive, both sheet or film and layer of adhesive being non-occlusive. The term " non-occlusive " is defined as meaning that the passage of water vapour is permitted. The thin sheet or film may be cast from a polyvinyl chloride composition which prior to casting may be modified by one or more of the following: (a) incorporation of a filler, e.g. sodium chloride or starch, to be leached out for forming the necessary pores; (b) incorporation of fillers which are not leached out and which transmit water vapour, e.g. calcium carbonate and diatomaceous earths; (c) incorporation of various gelatines, starches, or water-sensitive cellulose derivatives; (d) incorporation of liquids, e.g. water, glycerol, diacetin (a di-acetate of glycerol), by emulsifica-. tion if incompatible with the film mix ; (e) incorporation of gases, e.g. air, carbon dioxide, by spreading a foamed mix, or by including a blowing agent in the mix. The waterproof pressuresensitive adhesive composition may be similarly modified, more specifically by (a) sodium chloride being incorporated before spreading and leached out after spreading; (b) water being incorporated in the form of an emulsion with the solvent mix before spreading, the water being dried out with the solvent after spreading; (c) the composition being foamed by the addition of methyl cellulose to the aqueous phase of (b) prior to emulsification, foaming taking place in the mass after it has been spread. As shown in Fig. 2, the pressure-sensitive adhesive may be spread as a pattern, e.g. an openwork fine line pattern, as described in Specification 819,635, on the thin sheet or film which has previously been made non-occlusive. The nail coating may be made non-occlusive by simultaneous mechanical perforation of the thin sheet or film, and the coating of adhesive, as described in Specification 822,051. As shown in Figs. 5 and 6, the adhesive surface 20 of the nail coating may have a strip 21 of pliable plastic material mounted thereon to facilitate manipulation of the nail coating during application to the nail 22 as shown in Fig. 7. Nail coatings of various suitable sizes may be produced in rows, as shown in Fig. 10, the rows being advantageously mounted on a common backing 26 as shown in Fig. 8, and may be packaged in a wallet as shown in Fig. 12.

Abstract: 1,174,685. Measuring circuit time delays. AGA A.B. Feb. 21, 1967 [April 28, 1966], No. 8105/67. Heading G1U. A method of characterizing the delay if a signal path comprises the steps of passing two signal frequencies having a fixed ratio through the path, marking the times of phase equality of the two signals before and after passing through the path, and representing the interval between the marked times by the length either of a single pulse or of a train of pulses having a fixed frequency. In a first embodiment, Fig. 1 (not shown) two oscillators (01, 02) respectively feed signals of frequency nw and (n + 1) w to a signal path (DL) and detectors (D1, D2) respectively at the input and output of (DL) produce pulses when the signals simultaneously pass through zero in the same direction, these pulses controlling a multi-vibrator, the length of whose output pulse P indicates the delay of the path (DL). In a circuit providing a binary digital output, the signal frequencies are obtained from a master oscillator G1 through a frequency divider DC1 and from a second oscillator G2 whose frequency is locked on (n + 1) w with the aid of a mixer MX and phase detector FD. DC1 and a second frequency divider DC2 are built as scale of 2 counters, and a detector DT1 operates a flip-flop FF1 to connect a memory M1 to the output of DC1 when the output signal of frequency nw passes through zero in the positive direction. When the output signals achieve phase equality an AND gate A operates a second flip-flop FF2 to connect a second memory M2 to DC2, the counter outputs taken together indicating the delay in the signal path DC1, DC2. The activator FF1 may be emitted and both memories controlled by the AND gate A.
