Title: Improvements relating to the lubricating systems of internal combustion engines
IPC: F01M5/00
Filed: 1950-10-31
Abstract: 684,436. Lubricating. DAIMLER-BENZ AKT.-GES. Oct. 31, 1950 [Oct. 31, 1949], No. 26537/50. Class 12 (iii). In an internal combustion engine lubrication system, more especially for starting lubrication, lubricant is supplied directly to the piston tracks in the cylinders from the main lubricant pump, and in dependence upon the pressure or temperature of the lubricant in the main lubricant pipe system. Oil from the sump 2 is supplied by a pump 3 to a pipe 4 from which the oil normally flows through branch pipes 5 to crankshaft bearings 6. A spring-loaded valve 9 is connected to the pipe 4 and is arranged to open at a predetermined pressure to supply oil to the cylinders through a pipe 10 and bores 11. A second spring-loaded valve 13 may be arranged in the pipe 10 through which excess oil may be returned to the sump through a pipe 14. In a modification, a second excess pressure valve 15, Fig. 2, is connected to the pipe 4 and is arranged to open at a pressure below that at which the valve 9 opens, but is only fully opened at a higher pressure than the latter. In a further modification a piston slide valve 17, Fig. 4, is arranged between the pipes 4 and 10, and is operated by a pivoted lever and rod 18 connected to a thermostat 19. Alternatively the thermostat 19 may be replaced by a device responsive to the viscosity of the oil, comprising a spring loaded piston 23, Fig. 5, secured to the end of the rod 18 and disposed in a cylinder 21 having a slightly conical throttle groove 24 in the wall thereof. Oil is supplied through a pipe 20 and returns to the sump through a pipe 25. A filter 17 is incorporated in the main lubricating circuit.

Title: Method of and apparatus for testing time intervals
Inventor: HODGSON ERIC DOUGLAS
IPC: G04F10/00
Filed: 1957-08-22
Abstract: 844,175. Faulty testing; time interval measurement. BURGESS PRODUCTS CO. Ltd. Aug. 22, 1957, No. 26579/57. Class 37. Apparatus for measurement of a time interval e.g. of the operation of a microswitch comprises a relay of accurately known and/or adjustable dropout time which is normally energized through a circuit which is broken at the beginning and is remade at the end of the time interval if the latter is not longer than the relay dropout time; the relay contacts being arranged to operate one indicating device when closed and another when opened to indicate a time interval in excess or in defect of the realy dropout time. In Fig. 2 a double pole changeover relay D is excited from the rectified output of a transformer over switch PS momentarily closed to preset the relay to hold over closed contacts x, z and lamp F in series with the normally closed contact NC of a test microswitch ST, while lamp A is energized over closed contacts 1, o. Relay D is shunted by plural variable resistances P 1 , P 2  selectible by switch SS, and on operation of microswitch ST contacts NC are opened and contacts NO closed. If the changeover time is less than the preset relay dropout time, relay D remains energized, lamp A remains illuminated, lamp F is extinguished and lamp G illuminated ; indicating satisfactory switch operation within the preset time interval. If the changeover time exceeds the relay dropout time, relay D is deenergized to extinguish lamp A and illuminate lamp B, while lamps F, G are both extinguished ; indicating a faulty microswitch. The test switches may be fed continuously by a conveyer which automatically operates preset switch PS for each test, while additional contacts of D may operate a rejecting solenoid for each faulty unit. Calibration may be effected by repetitively and successively closing and opening contacts NC, NO while adjusting P 1  or P 2  until relay release coincides with illumination of lamp G.

Title: Driving Arrangement for the Drum of a Wahsing Machine.
IPC: D06F34/08
Filed: 1969-05-27
Abstract: 1,195,179. Control of D.C. motors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 27 May, 1969 [30 May, 1968], No. 26764/69. Heading H2J. [Also in Divisions D1 and G3] A commutator motor 1 which drives a washing machine at high and low speeds is supplied through the heating element 7 whereby its speed decreases to a lower value than is normal with an increasing load. A switch 8 enables the element 7 to be connected directly to A.C. mains 2, 2<1>, to accelerate the heating of water in the tub. A switch 10, 10<1>, reverses the motor, whilst a thyristor 9 provides control of washing speed. The tub is first filled with water through valve 18 opened by device 17. A level detector 20 starts the motor 1 through cycle counter 16 under the control of heater 21 and temperatureresponsive resistor 22. A reversing circuit 12 causes the motor to run in alternate directions for set periods, with a pause between each period during which the element 7 is supplied directly from the mains. When the temperature of the water reaches a set value, a pump motor 13 is switched on until a unit 24 detects that the tub is empty. A second cycle is similar to the first except that the tub is now filled through valve 19, the on-off periods of the motor 1 are changed, and the temperature limit is altered. Several rinsing cycles follow, some without heating during the intervals, the programme-step controlled by heater 21 and resistor 22 being omitted. The spin-drying operation commences before the tub is fully drained, the reversing circuit 12 being rendered inoperative and low power being dissipated in the heating element. If the door is opened during operation, the supply circuit is opened and the motor is short circuited across the element 7. In another arrangement, a full-wave rectifier 30 is connected between the motor circuit and the supply, the switch 8 is replaced by a shortcircuiting switch 8<1>, and a flywheel diode 31 is connected across the motor. In a first position a of a speed-selector switch 38, Zener diodes 36, 37, delay the firing of thyristor 9 so that the washing speed is stabilized by counter-action of the back-E.M.F. in the cathode circuit of the thyristor. In position b, the firing of the thyristor is more delayed since the back-E.M.F. is now compared with the voltage across Zener diode 37 only. In position c, Zener diodes 34 are short-circuited, the back-E.M.F. being compared with the voltage across resistor 39. The motor is supplied with substantially complete half-cycles in position d for the spindrying operation. In a further embodiment, the element 7 is connected on the A.C. side of the bridge rectifier, the element being tapped so that a portion may be short-circuited by contacts of a speed-responsive switch.

Title: Improvements in and relating to the distillation of water and other liquors
Inventor: RHODES CECIL
IPC: B01D1/26
Filed: 1963-07-08
Abstract: 1,028,516. Multi-stage evaporation; distillation of water. AITON & CO. Ltd. July 8, 1964 [July 8, 1963],No.26879/63. Heading B1B. Liquor is submitted to evaporation in a multiple-effect evaporatory, the heater of each effect 2 being of the vertical tube type, and the liquor withdrawn from the last effect is conducted to flash evaporation plant 1. The apparatus may be used for the distillation of water, or for the concentration of caustic soda solution, yeast extract, or glue. Water to be distilled enters the apparatus through line 5 and flows as cooling-medium through the condensers 3 of flash plant 1. The water then flows through the condenser 6 of a subsidiary flash plant 7 and through the condenser 8 of the ejector pumps 9, operated by steam, which extract non-condensable gases from plant 1. The water next flows through a series of preheaters 10, each of which is associated with an effect of the multiple-effect evaporator. The preheated water then enters the lower end of the tubes of the first effect A, which is heated by steam supplied through line 11. The vapour formed in A is withdrawn through line 12, and is conveyed in part to the associated preheater 10 and in part to the heating jacket of effect B. The condensate formed in preheater 10 also flows to the heating jacket of effect B. Water flows from the tubes of effect A to the tubes of effect B through line 14. The water leaving the last effect flows to flash plant 7, where some of it vaporizes; the vapour is condensed in condensers 6, and the condensate is added to the distillate withdrawn through line 16 from the heating jacket of the last effect. The water leaving plant 7 flows through line 17 to the main flash plant 1; and the vapours evolved therein are conducted to condensers 3 and 4, the condensate being added to the distillate. The residual water withdrawn from plant 1 through line 19 may be in part recirculated through condensers 4 a heater 20 to the input of plant 1. Heater 20 is heated by the vapours issuing from the last effect through line 21. The condensate from heater 20 is added, together with the distillate from the preheater 10 of the last effect, to the main distillate. Distilled water is withdrawn from the system through line 18.

Title: Improvements in or relating to apparatus for and method of making boiler headers
IPC: F22B17/18
Filed: 1928-09-20
Abstract: 316,049. Cain, J. J. Sept. 20, 1928. Steam generators.-Boiler headers are made by mounting a tubular blank on a collapsable mandrel, and corrugating the blank by dies which engage the work first at one end and operate to form the finished header in a progressive manner from end to end. The apparatus comprises a pair of side die-holders 8, pivoted at 10 and a top die-holder 14 pivoted at 15. The side-die holders are guided by a yoke 20 in which pressure screws 21, 24 are mounted to force the side dies and the top die into contact with the work. The die-holders may alternatively be actuated by fluid-pressure &c. The side dies 6 are formed with inclined corrugations, and are staggered to produce a sinuous header. The top-die is formed with a serrated working face, to form the flats in which the boiler tubes are secured. The mandrel comprises top and bottom members 35, 34, Fig. 9, with longitudinally inclined interface, and side members 38 carried in slots in the top and bottom members, the side members having each a wedge face 40 to facilitate removal of the mandrel. The operative faces of the mandrel members are shaped similarly to the dies with which they coact.

Title: Safety device for automobiles, the gas valve and brake of which are operated by one and the same pedal
Filed: 1932-09-29
Abstract: 396,241. Controlling motor vehicles. CHRISTIANSEN, M. A. A. P., 12, Ole Olsens Allee, Hellerup, Denmark. Sept. 29, 1932, No. 27109. [Class 79 (v).] In motor vehicles of the kind in which the accelerator is closed and the brake actuated by continued depression of a single pedal, means are provided whereby the power impulses of the vehicle are caused to cease at the moment the pedal is released, said means being capable of being rendered inoperative by a device for restricting the power impulses to a predetermined value. The combined accelerator and brake pedal, Fig. 1, is provided with an inset plate 2 controlling a switch in the ignition circuit 3, 4. If, while the master throttlecontrol 5 is wide open as shown, the driver's foot slips off the pedal the plate 2 rises relative to the pedal and breaks the ignition circuit. When the control 5, however, is partially closed, a separate ignition circuit 10, 9 is permanently completed through the contact strip 8 and pin 7. In the modification, shown in Fig. 2, the pedal 1 on being depressed to apply the brake acts through a rod 18, cord 17, and drum 15 to rotate a shaft 13 in a clockwise direction against the action of a spring 14, thus causing a pin 24 attached to the throttlecontrol rod 19 to slide towards the point B of a slot BL concentrically placed in a pulley 16 fixed to the shaft 13, thus keeping the throttlelever L<1> in the closed position shown in firm lines. As the pedal 1 is allowed to rise, the spring 14 rotates the shaft 13 in an anticlockwise direction so that the pin 24 moves towards the point H in a continuation of the slot BL, thus moving further from the centre of the pulley 16 and pushing the rod 19 and lever L<1> towards the open position shown in dotted lines. If the pedal is accidentally released altogether, the shaft 13 rotates further in an anticlockwise direction until the pin 24 reaches the point L<1> of the slot and the throttle is again closed. At the same time a pin 27 strikes a contact 28 and operates a warning lamp or buzzer. The safety device may be put out of action by a spiral lug on the shaft 13 coming against an adjustable and removable arm 20 when the pin 24 is in some part S of the slot corresponding to a limited opening of the throttle.
