Filed: 1956-06-13
Abstract: 812,019. Manufacturing incandescent lamps. SYLVANIA ELECTRIC PRODUCTS Inc. June 13, 1956 [June 17, 1955], No. 18315/56. Class 39(2) For adjusting the orientation of lamp mounts carried by a conveyer in a lamp making machine, each mount is formed with a pair of opposed flattened areas and is adjusted by means of two co-operating fingers adapted to press one against each of the flattened areas. In the form shown, the positioning fingers 35, 57 are operated by a push rod 27 actuated by a cam on the driving shaft of the machine, which moves cranks 25, 53 carrying members 31, 55 on which the fingers 35, 57 are pivotally mounted. The fingers may be spring loaded so as to exert equal forces on the lamp mount presses. Operation of the fingers causes the mount to rotate until the presses are in the plane of the end faces of the fingers. In a double indexing turret machine, the pairs of fingers are duplicated to bear on mounts in two adjacent holders in the turret. The absence of a mount in one of the holders may be detected by a compressed air jet 75 directed at the flare of the mount 77. In the absence of a mount, the air jet strikes the baffle 80 of a microswitch or similar device which acts to prevent the apparatus for placing bulbs on the lamp mounts from operating to supply a bulb to this position on the turret. To avoid contamination of the mount by foreign matter, a filter of sintered bronze may be provided in the supply pipe of the compressed air jet.

Title: Improvements relating to mechanism for doling out predetermined quantities of liquid
IPC: G01N25/42
Filed: 1926-07-22
Abstract: 270,132. Trade, Secretary of the Board of, and Boys, C. V. July 22,1926. Calorimeters. - Mechanism for delivering weighed quantities of liquid at predetermined intervals of time, for use particularly in connection with gas calorimeters such as that described in Specification 180,080, comprises a counterweighted balance beam supported in a condition of unstable equilibrium and pivotally carrying a tipping bucket on one of its arms, and a liquid feed jet adapted to feed liquid to the bucket in a direction substantially parallel to the tipping axis of the bucket. The tipping bucket 3 is pivoted upon a balance beam 1 resting on knifeedged bearings 2 disposed below the centre of gravity of the beam system. Stops 4 limit the movements of the beam. Counterweights 5, 7 provided with lock-nuts 6, 8 are carried on a screw-threaded portion of the beam, and the counterweight 5 may be graduated so that each unit of the graduations corresponds to one gramme in ten tilts of the bucket thus facilitating a change of setting. The bucket is provided with a counterweight 18 and a lock-nut 19, and the trunnions of the bucket are situated so that the centre of gravity of the charged bucket is above the trunnions. The bucket is charged through a tubular receiving spout 13 by means of an horizontal jet which strikes the spout at the spot 14. When the requisite weight has entered the bucket, the beam, owing to its unstable equilibrium moves rapidly to its upper stop 4 and the spout 13 is quickly removed from the path of the water jet. When the beam reaches its upper stop the bucket tips and discharges its contents. In the discharging position a pawl 11 engages the pouring lip of the bucket and retains it until liberated by a push rod 12 controlled by a clock movement. A pair of metal strips 24 on the pawl 11 serve to drain the bucket by capillary action. On the return movement of the bucket an arm 10 thereon strikes a swivel piece 16 carrying a feather 15 which is thus caused to make a rapid movement through the air and cushion the return. An arm 9 limits the tipping movement in the discharge position.

[Also in Group XXXIV] In a gas turbine exhaust cone assembly comprising inner and outer casings connected by aerofoil spokes, a shaft bearing at the rear end of the turbine is supported by a diaphragm having, in cold conditions, an interference fit in the inner casing in the region of the spokes, and a plurality of angularly-spaced pins are provided to locate the diaphragm relative to the inner casing in all directions except the generally radial direction. The arrangement allows the inner casing to expand freely radially but maintains the concentricity and alignment of the diaphragm and inner casing. The exhaust cone shown comprises an outer casing formed in two parts 30, 31 connected to the turbine stator casing support 33, an inner casing 17 which carries a conical extension 24 and spokes 25 connecting the parts 17, 31. The rear turbine bearing 13 is carried by a diaphragm 11 formed with a rim 16 which has, in cold conditions, an interference fit with a ring 18 attached to the inner casing 17. Screws 21 mounted in the rim 16 have a plain pin portion 22 which engage the ring 18. The screws 21 are arranged truly radially in the end view of the diaphragm but in the axial section shown are slightly inclined to the radial. This arrangement allows the inner casing to expand freely radially and also facilitates the drilling of the screw holes. The rings 16, 18 may also be made of a lighter construction. The chamber enclosed by the inner casing 17 and conical extension 24 is open to atmosphere and is insulated from the hot gases by lagging 27, 28.
