Title: Improvements in or relating to lamp brackets
IPC: F21V21/02
Filed: 1939-02-22
Abstract: 525,479. Lamp brackets. GEORGE, L. T. Feb. 22, 1939, No. 5842. [Class 75 (iii)] A wall lamp comprises a fixed wall bracket 1 incorporating an electric socket terminal 16, and a part 8 which carries an electric lamp-holder 10 and a plug terminal 14, the part 8 being detachably supported by the bracket 1.

Title: Improvements in reciprocating pumps
IPC: F04B53/10
Filed: 1941-05-06
Abstract: 549,823. Reciprocating pumps. HUNT, W. F., and HUNT, O. F., (Representatives of ZWICKY, J.) May 6, 1941, No. 5857. [Class 102 (i)] A reciprocating pump having inlet and outlet tappet valves arranged in planes parallel with the cylinder axis is made reversible by mounting the valve seatings and valves so that they can rotate as a unit through an angle of 180 degrees about an axis parallel with the seatings and with respect to which the valves are symmetrically disposed. This axis of rotation may be parallel with the cylinder axis, or at right angles to it though not intersecting it. Alternatively, as shown, the valve seatings may be in planes parallel with and on opposite sides of a plane containing the cylinder axis; the valve axes are then at right angles to the cylinder axis and do not intersect it, and the axis of rotation is at right angles to the cylinder axis and intersects it. The rotatable structure comprises two parallel plates 6, 7 containing the seats for spring-pressed inlet and outlet valves 14, 15, a transverse partition 8, and two discs 9, 11 fitting the valve chest 1. The stems of the inlet valves 15 are received in the hollow stems of the outlet valves 14, while the stems of all of them slide in cross-bars 13, 16. The structure is rotated by a handle 34 which is held in its operative positions by a spring-pressed plunger 35 (not shown), and a strainer 17 may be mounted on a boss 18 on the inlet side of the valve structure. The pump may be short circuited by a spring-pressed relief valve 29 mounted in the boss 18 and controlling lateral openings 28 between the inlet and outlet 4, 5. The pump may be power driven or hand operated, in which latter case rocking of a handle 19 is limited by pins 26 covered with rubber sleeves 27.

Classes 37 and 41. The surface of a semi-conductor, e.g. germanium, silicon, indium antimonide, is cleaned by anodic etching in an oxygen-free non-aqueous solution of an inorganic salt of high dielectric constant. By subsequently reversing the current the cleaned surface is electroplated. As described, a germanium crystal and a copper rod connected through a reversing switch to a variable D.C. supply are immersed in a saturated formamide solution of copper chloride beneath a dry atmosphere of argon, whereby the crystal is first cleaned and then plated with copper. The surface area treated may be stopped off as desired. A low-resistance contact may be made by soldering to the plated area of the semi-conductor.

In a method of applying treatment media to moving elongate materials, particularly dyeing travelling yarns, the treatment media is fed intermittently and under the control influence of pneumatic means to a treatment station through which the material passes. One embodiment of apparatus for carrying out the method comprises a body part 11, having two vertically spaced, horizontally disposed through-bores 12, 13, and a vertically disposed feed conduit 14 passing through and communicating with the bores 12, 13. The upper bore 12 is provided with a valve member 17 which is reciprocated by suitable means e.g. a cam, according to a predetermined cycle. The valve member 17 is provided with a portion 17a of reduced diameter which in the open position of the valve member allows treatment media to be drawn up the conduit 14 from a reservoir 15 by virtue of a reduced pressure produced at 16. The junction of the conduit 14 with the lower bore 13 through which the material passes forms the treatment station. The treatment media may be forced up the conduit 14 by virtue of an increased pressure in the reservoir. A second embodiment is described in which the valve member is of the form described in Specification 1133196.

Glass sheets are bent and tempered by being supported across moulds 26 which are traversed through a heating chamber 3 provided with movable heat shields 87 to shut off selected portions of the sheets from the effect of the radiant heaters 92 to permit some portions to be heated to a higher temperature to assist the accurate bending of the sheets. Alternatively the heat shields may be carried by the moving moulds. Before leaving the chamber 3, the bent sheet is uniformly heated on both sides e.g. by blankets of flame from burners 108, 109. After leaving the chamber 3 the bent sheets are quickly passed to the tempering apparatus 6 through which it passes more slowly. The tempering apparatus includes convex nozzles 18 and concave nozzles 21, shaped to the section of the bent sheet, which deliver cooling air from upper and lower chambers 17.

Abstract: 956,958. Screw jacks. JOYCE-GRIDLAND CO. Feb. 20, 1963 [Feb. 26, 1962], No. 6760/63. Heading B8J. A nut assembly 12 of a worm gear screw jack supports a jack screw 14 and comprises two sections 30, 32, which, when their threads wear, may be moved closer to each other to clamp the sections into firm engagement with the thread of the screw 14 to reduce backlash therebetween. The nut sections are connected by pins 33 located within aligned apertures. A tube 20 and cap 24 protect the lower portion of the screw 14 which is prevented from rotation, e.g. by attachment of a pad 18 with a load. When the jack is initially assembled, there is a gap between the bottom surface of a bearing cap flange 50 and the top surface of a main housing 10, and lock screws 52 are tightened on the housing. When backlash becomes apparent, the lock screws are loosened and the cap 16 is screwed down, thus causing a thrust bearing 34 and the nut section 30 to move downwardly. With the backlash taken up the lock screws 52 are retightened.
