Title: Device for utilising the reactive force set up by rotating a screw propeller or screw fan or the like in a fluid
IPC: B64C23/00
Filed: 1921-10-26
Abstract: 192,452. Chaddock, G. A. Oct. 26, 1921. Propelling by water jets; screw propellers. - Screw propellers are surrounded by annular deflectors which deflect the incoming currents at the periphery rearwardly into the direction of the main flow to increase the efficiency of the propeller. Where an increased thrust, as distinct from an increased volume of fluid displaced, is desired, the peripheral inflow may be promoted by restricting the frontal inflow, this purpose being served by the forward bulk of a marine vessel. The deflector supports are arranged to counteract the rotary character of the wake from the propeller, and additional denectors for this purpose may be fitted at the rear. Fig. 3 shows a propeller 3 'having a series of inclined blades 1 surrounding it and carried by radial supports 2. The supports 2 carry hinged extensions 4, to counteract rotary wake, bearing against spring stops 5. Should the propeller stop the spring stops 5 assist the extensions 4 to close up the disc area and prevent back flow, or, when the propeller is used for supporting an aircraft, to check the fall. The extensions may also be controlled manually. The propeller shaft may be supported in front by a central tubular member carried by flat stays of the same length. According to the Provisional Specification the hinged extensions may be of slightly arched section.

Title: Improvements in and relating to control arrangements for refrigerators
IPC: F25D23/12
Filed: 1951-12-06
Abstract: 688,184. Refrigerating. BRITISH THOMSONHOUSTON CO., Ltd. Dec. 6, 1951 [Dec. 29, 1950; Dec. 29, 1950], No. 28640/51. Class 29 In a refrigerator having an auxiliary insulated compartment for e.g. butter provided with an electric heater 15, means are provided to energize the heater either whenever the supply of current to the motorcompressor unit 29 is interrupted or whenever a solenoid-operated valve supplying refrigerant to an evaporator is closed. As shown in Fig. 3, the heater 15 is connected across the contacts 20, 21 of the thermal switch controlling the supply of current to the motor 29. The thermal switch may be constructed as described in Specification 451,832. As shown in Figs. 6 and 7, a rheostat 34 is connected in series with the heater 15 and is mounted on the spindle 27a of the knob 6 controlling the response of the thermal switch and hence the temperature of the refrigerated space. The colder the refrigerator, the more heat must be supplied to the butter compartment and this is ensured by less of the rheostat 34 being in circuit when the knob 6 is rotated to a colder setting for the refrigerator. In addition, the rheostat can itself be rotated to give one of three temperature settings for the butter compartment. The slider 38 of the rheostat 34 is keyed by a spigot and socket 39, 70 to the knob 6. As shown in Fig. 4, a bellows 50 responsive to the temperature of a high temperature evaporator 91 serves to cause conducting elements 55, 56 to bridge either contacts 54 to energize the heater 15 or contacts 48 to energize a solenoid 46 to open a valve 45 supplying liquid refrigerant to evaporator 91.

Title: Improvements in relating to electrical turning gear for starting internal combustion engines
Filed: 1926-11-18
Abstract: 280,709. Royce, r. H. Nov. 18, 1926. Starting prime movers.-An electric system for starting internal-combustion engines comprises a battery a, a motor b, and a pinion b<1> on the motor shaft' movable axially by an electromagnet into engagement with a toothed wheel b<2> attached or geared to the engine shaft. A main circuit, indicated on the drawing by unfeathered arrows, is controlled by a switch d<6> operated by an electromagnet c<1> connecting the battery to the motor, and three subsidiary controlling circuits are arranged as indicated by arrows having respectively one, two, and three feathers. According to the invention, a conductive rocking member d forms part of the first and third controlling circuits, opening the first at d<3> and closing the third at d<2> in one extreme position and vice versa in the other, and the armature d<4> of the electromagnet c<1> controlling the main switch d<6> engages the member d for movement in one direction but not the other. As shown, the member d and the armature d<4> are mounted on a common pivot d<1> and the armature d<4> has at one end a projection d<5> which engages the member d when moving in one direction. The pinion b<1> is mounted on the motor shaft, which is moved axially against a spring b<4> by an auxiliary field winding on the motor in series with the first controlling circuit. On closing the first circuit by means of a hand switch f, the motor is slowly turned and the pinion brought into engagement with the wheel b<2>, and an extension b<3> on the motor shaft closes a shaft c in the second circuit. The electromagnet c<1>, is thus energized, rocking the armature d<4> and member d; the main circuit of the motor is closed at d<6> by the armature d<4>, and the member d breaks the first circuit at d<6> and closes the third circuit at d<2> through an electromagnet e. When the engine starts, the diminution of current through the motor binding allows the spring b<4> to return the pinion b<1> and the motor shaft to normal position and to open the switch, c, but the electromagnet c continues to hold the member d until the hand switch f is released.

Title: Method and an apparatus for inserting elongated articles into a plurality of holes in a carrier substantially flat surface of a substrate
IPC: H01R43/20
Filed: 1972-06-23
Abstract: 1393931 Orientating articles INTERNATIONAL BUSINESS MACHINES CORP 23 June 1972 [31 Aug 1971] 29417/72 Heading B8S Articles, e.g. headed pins, are positioned in holes in a carrier by vibrating the carrier while applying a pulsating pressure differential which induces a gas flow into the holes thus assisting articles into the holes. Apparatus shown in Fig. 9 includes a carrier 170 mounted on a vibrator 110 by means of a carrier support 120. Articles are introduced to the carrier through hopper 182. A vacuum is applied to the carrier so that suction will attract the articles to the holes and the carrier is vibrated so that the articles move across the carrier. The vacuum supply is periodically cut off so that a correctly positioned article (e.g. article 320 in hole 350, Fig. 14) remains there while incorrectly positioned articles are moved by vibration when the vacuum is cut off. When the vacuum is returned, loose articles are once more attracted to empty holes. The process is repeated until all holes are filled with correctly positioned articles. Excess articles are then removed from the surface of the carrier by frame 192, a mask is placed over the carrier and bonding material is applied over the mask so that only the heads of the articles are coated. The mask is then removed, a substrate is placed on top of the carrier and the assembly is inverted. A weight fixture is placed over the assembly applying pressure to each article individually (see Fig. 7, not shown), the assembly is heated to set the bonding material and the weight fixture and carrier are then removed, leaving the substrate with articles bonded to it (see Fig. 8, not shown). The method of bonding is described and claimed in Specification 1,393,932.
