Title: Improvements relating to burners
Inventor: BETTERIDGE CECIL GEORGE
IPC: F23D11/00
Filed: 1960-04-08
Abstract: 919,081. Burners. FUEL FIRING Ltd. April 5, 1961 [April 8, l960], No. 12659/60. Class 75 (1). ). During retraction of an oil burner from an operative position to an inoperative position scavenging air or steam is passed into the burner and the retraction is interrupted for a predetermined period to extend the scavenging period. The burner (not shown) is moved by a drive tube 1 connected by rods 12a, 13a to pistons in pneumatic or hydraulic cylinders 12, 13. When a switch is thrown the fuel supply to the burner is cut-off, scavenging air is passed into the burner and a solenoid valve 9 is energized to pass compressed air from a line 10 through a line 8, a cut-off valve 7 and a line 11 to the cylinders 12, 13 to retract the burners. A roller trip 2 mounted on the drive tube 1 actuates a valve 3 to pass compressed air via lines 5, 6 to the cut-off valve 7 which then closes the line 11 to the cylinders to stop the retracting movement. After a time determined by an adjustable timer in the cut-off valve the latter again opens the line 11 to the cylinders so that the retracting restarts. At the end of the retraction the solenoid valve 9 is automatically de-energized and the scavenging air is out off. The burner is returned to the operative position by the solenoid valve 9 directing the compressed air along line 15 to the other ends of the cylinders. In a modification the compressed air for actuating the cut-off valve 7 is also controlled by the solenoid valve 9. Specification 734,077 is referred to. _

Title: Apparatus for mounting a semiconductor component in a support
IPC: H01L21/52
Filed: 1966-03-24
Abstract: 1,082,421. Semi-conductor devices. SIEMENS SCHUCKERTWERKE A.G. March 24, 1966 [April 3, 1965], No. 13155/66. Heading H1K. [Also in Division G1] Apparatus for inserting a semi-conductor component 3, Fig. 1, into a recess 2a in a support member 2, is associated with testing circuitry for checking the electrical characteristics of the inserted component. The apparatus consists of an open-ended plunger 4 which is used to press the component into the recess, the open end containing a spring-loaded contact 9 for completing the connection to the testing circuit 10. The test circuit of Fig. 2 provides a polarity test in which the inserted component, a rectifier, is energized by an A.C. source 25 and its output applied to a relay-plus-rectifier combination 18, 19, 23, 24 which moves a contact 20 on to one or other of two fixed contacts 21, 22 in accordance with the polarity of the inserted rectifier. This polarity test also controls the operation of further relays R 1 , R 2  which control the polarity of the applied potential in a current-voltage characteristic test. The current-voltage characteristic test may take the form of checking the voltage which appears across the rectifier 33, Fig. 3, when connected in series with a resistor 34 and a D.C. supply 40, the polarity of the supply being such as to produce reverse bias of the rectifier. This test may be performed both before and after pressing the rectifier into its recess: the pre-pressing voltage may in this case be stored by a capacitor 36 and the post-test voltage, if lower, will cause a partial discharge of the capacitor, the discharging current being metered at 38 and, if it exceeds the permitted value, operating an alarm 39.

Abstract: 514,501. Mounting electric batteries on vehicles. MORRISON, A. C., and ASSOCIATED ELECTRIC VEHICLE MANUFACTURERS, Ltd. May 7, 1938, No. 13690. [Class 79 (iii)] Batteries are mounted' in electrically propelled vehicles by means of T irons, or other members providing a lateral fin like flange or projection, attached to the sides of the battery boxes and adapted to ride between rollers or other antifriction members carried by the vehicle frame. The T irons or the like are extended beyond the battery so as to be still supported between the rollers &c. when the battery is partly withdrawn for inspection &c. and also to facilitate re-insertion after complete withdrawal. In the form shown in Figs. 4 and 5, bars 3 with horizontal flanges 3a attached to the sides of a battery 1, are adapted each to be supported between a pair of lower rollers 19, 20 and an upper roller 21 carried on the vehicle frame, the bars extending beyond the boxes so that the battery may be still supported when partly withdrawn. When inserting a battery the ends of thebars may test on the rollers 20 while the battery is lifted, then being pushed in under the rollers 21. The rollers 19 may, as shown, be somewhat lower than the rollers 20 so that, with weighing down of the frame, the battery 1 is horizontal when partly withdrawn for inspection. The bar 3 at one side of the box may be lower than the other, so that when batteries are inserted from opposite sides of a vehicle the projecting ends of the bars may overlap. The rollers 19... 21 are carried by brackets 7 attached to the vehicle frame members 4, opposite brackets being braced by a cross beam 10. Each bracket comprises a pair of plates 8, 9, bolted to the cross beam 10 and secured to the frame member 4 by angle plates 11, one of which is extended to reinforce a bracket 16 to which one end of the vehicle spring 6 may be attached. The rollers are each rotatably mounted on the projecting end of a sleeve 24 passing through and welded in the plates 8, 9, being held thereon by a washer on the end of a bolt passing through the sleeve and secured by a nut 28. Modifications are described, one in which, Figs. 10... 16 (not shown), with a lower vehicle frame, the lower rollers are directly mounted in a cross beam resting on the frame longitudinals whilst the upper roller is mounted in a bracket attached to the beam, and another, Fig. 17 (not shown), in which, with a combined body and frame, the rollers are carried by brackets attached to the underneath part of such frame.
