Title: Improvements in or relating to electrical connectors and to methods of and apparatusfor forming electrical connections
Inventor: COBAUGH ROBERT FRANKLIN
IPC: H01R43/027
Filed: 1963-03-04
Abstract: 1,009,675. Direct connections between conductors. AMP Inc. Feb. 21, 1964 [March 4, 1963], No. 8564/63. Addition to 956,118. Heading H2E. [Also in Division B3]  A method of connecting an electrical conductor to a terminal post is substantially the same as that disclosed in the parent Specification in which a generally channel-shaped resilient connector is pushed along a guide to engage and draw a conductor, which may be insulated for example with vinyl or P.T.F.E. on to the post and clamp it thereon but the claims and description are directed to a method of making the connection on an edge face of the post. A connector comprises a rectangular portion 3 having an internal width less than the conductor core 12 diameter and an insulation supporting cylindrical portion 7. The connector is pushed along a T-shaped guide 17, the end of which engages the curved end of a post 8. It first engages an end portion of a conductor 9 inserted in an inclined slot 20 of the guide so as to shear the insulation therefrom and then moves the conductor downwards on to the post 8, the leading end portion of the insulation being engaged by the portion 7. The anvil end of the slot 20 may be formed with cutting edges defining blades.

Title: Improved Method of and Means for Protecting Vessels against Torpedoes and Mines, applicable also to the Propulsion and Raising of Submarines.
Inventor: FERNANDEZ ALBERTO ZEGERS
IPC: B63H11/00
Filed: 1917-06-15
Abstract: 118,127. Fernandez, A. Z. June 15, 1917. Protecting.-Vessels are protected against mines and torpedoes, or submarines are propelled or elevated by means of jets of water and water mixed with air, which are projected from the vessel in a downward and backward direction by means of centrifugal pumps or turbines. The projecting nozzles comprise a number of vertically flattened nozzles e. Figs. and 3, on each side of the vessel arranged in vertical rows. and in front of the vessel two vertical rows of vertically flattened nozzles b, and an horizontal row of horizontally flattened nozzles a. The nozzles a and b in front of the vessel are supplied through pipes a<1>, and are supported by a pivoted fitting c capable of being raised from or lowered into the water. The water is taken up from the sea through tubes h, Fig. 7, opening forward so as to increase the suction effect of the pumps f, which is driven by a motor g or by a turbine, and is discharged at a lower level through the nozzle e. A fan-shaped distribution of the water and water and air is obtained by discharging the jets from the vertical rows of nozzles b and e at inclinations changing from lorizontal at the uppermost nozzle to a downward inclination of about 30 degrees at the lowest nozzle; while the nozzles a are also arranged to give a fan-shaped distribution. The air is mixed with the water by drawing it through pipes leading into the suction mouths h.

In a lamp as described in Specification 1,065,023 having an envelope 1 of material having an alumina content exceeding 85% by weight to which a niobium closure member 3 supporting an electrode 7 is sealed by a layer 5 consisting of at least one of the metals Ti, Zr, Va, Hf optionally together with Nb, as described in Specification 1,094,052, a shield 16 of refractory material is provided to protect the seal 5 from wandering of the discharge during starting of the lamp. The shield may be an annular disc of ceramic material similar to that of the envelope 1 fitted around the electrode 7 near the seal 5, or may be of metal, e.g. W or Mo, fitted near the discharge end of the electrode. Alternatively the shield may be a frusto -conical member of sheet metal or of coiled wire, in which case it may form an extension of either the innner coil 8 or (as shown) of the outer coil 15 of two tungsten coils retaining electron emissive material 9 on the electrode 7. A cylindrical extension 17 of the shield lies near the envelope 1. In a modification (Fig. 2, not shown), a frusto-conical coiled wire shield mounted with the narrow end towards the seal has at the wide end a cylindrical extension in contact with the lamp envelope and at the narrow end a cylindrical extension fitting closely around the electrode and in contact with the exhaust tube 12 or with the closure member. The lamp which has a filling of sodium, mercury and argon is mounted in an outer glass envelope.

Abstract: 828,355. Rotary-transmission dynamometers. NAPIER & SON Ltd., D. Feb. 4, 1958 [March 15, 1957], No. 8711/57. Class 106 (2). Transmission gearing with means for measuring the torque transmitted comprises an intermediate idler gear 13, the axis of which is in line with the axes of the gears 12, 14 with which it meshes and is mounted for bodily movement perpendicularly to the plane containing these axes and an hydraulic piston and cylinder 32, one of which moves bodily with the idler 13, and pressure indicating means 36. As shown, the idler gear 13 is connected to two pistons 18, 19 moving in cylinders 32, 33, to which oil is supplied under pressure from a pump 24. Movement of the pistons 18, 19, covers or uncovers relief ports in the cylinders, thus allowing the pressure to build up in one and decrease in the other. The difference between the pressures is a measure of the torque transmitted and is read from a gauge 36.

Abstract: 1,084,827. Screening apparatus. CHISHOLM-RYDER CO. Inc. March 1, 1966, No. 8838/66. Heading B2H.  A screen-drum for grading beans comprises a plurality of bars 21, 21 and articulated leaves 25, the latter being movable by means 29 for adjusting the grading clearance. The bars 21, 21' are supported in end plates 5 which are mounted on rollers 7 for rotation through a gear-ring 11. The leaves are hinged about an axis 23 and operated by toggle links. To decrease the clearance, the links are urged upwardly against the action of a spring 37 by a wedge-shaped member. 45 on a bar 43 when the latter is moved axially by a member 55. The member 55 is mounted by pins 63 in helical slots 65 of a support ring; to adjust the clearance, the ring is rotated by means of a handle 67, the clearance being indicated on a scale 80. Each bar 43 is urged by a spring 49 against a cam-surface 57 on the member 55 so that during rotation of the drum, the clearance is increased in the upper half of the drum to release beans which have become jammed. In another embodiment, Figs. 10-18 (not shown), the leaves are formed by resilient U- shaped members and are actuated by diamondshaped members (91) mounted on rotatable bars (93), each bar being mounted on a crank and roller assembly (95) which rides on an inclined surface of a ring (105); to adjust the clearance, the ring is moved axially against the action of at least one spring (115) by a handwheel (117). The ring is divided into two halves giving two different cam surfaces (103'), (103") to produce a larger clearance when rollers (101) of the crank and roller assembly ride on the upper half of the ring.

Abstract: 639,099. Drying webs. ALEXANDER, P. April 1, 1948, No. 9271. [Class 34(i)] Moisture is removed from the surface of moisture absorbent sheet material on which metal is to be deposited (by thermal evaporation in a vacuum) by heating one surface of the material in a vacuum chamber by radiant heat. A roll of the absorbent material is unrolled and progressively exposed in a vacuum chamber (pressure 0.05 to 0.5 mm. of mercury) to radiant heat and passed out of the heating chamber whilst hot to a communicating rerolling chamber in which the pressure is maintained at a higher pressure than that in the heating chamber so that one surface only of the web is freed of its moisture and plasticizer the vapour being prevented from gaining access to the re-rolling chamber. In the apparatus shown, a vacuum, heating chamber 1 is enclosed within a chamber 2, the chamber 1 having as a source of radiant heat an electric heater 3. The web 4 emanating from a supply roll 5 in the re-rolling chamber passes over guide roller 6, through slit 7 and into heating chamber 1 where it passes before the heater 3 and returns via collers 8 and 9 to the take-up roll 10 which is driven by a clockwork motor 11. In a modification the supply roll 5 is'in the heating chamber 1. In a second modification the two chambers are formed by dividing a single chamber by a partition.
