Patent GB-2035725-A (GB)
Title: Ignition circuit for a discharge lamp
IPC: H05B41/04
Filed: 1979-09-28
Abstract: The invention provides an ignition circuit for delivering an ignition pulse to an electric discharge lamp at the phase angle of the mains supply, specified by the lamp manufacturer. In the ignition circuit a main discharge capacitor C1 is connected in a phase shift network C1R2, so that the ignition pulse may be produced at a point on the charging cycle of the main discharge capacitor, at which the slope is relatively steep. In this way variations in the supply voltage will result in only small variations in the phase angle at which the ignition pulse is produced, thus enabling the ignition to stay within the manufacturers tolerances. Zener diode SD1 conducts at a capacitor voltage corresponding to the peak of the AC supply voltage, due to the phase lag produced by the circuit C1 R2 Figure 3 (not shown). Thyristor Q1 is thereby turned on to discharge capacitor C1 through the primary winding of step-up transformer T1 producing the ignition pulse. <IMAGE>

Title: Method and apparatus for attaching articles to a support card
IPC: B65B15/00
Filed: 1980-07-30
Abstract: In attaching a bag 8 to a card 2, a first reciprocating pusher j advances to deflect a tongue 3 out of the plane of the card. The bag 6 falls through a bag guide towards the card so that its sealed leading end 9 is received between the tongue and card. The first pusher j retracts and a second pusher c' advances to press the tongue back and thereby trap the end 9 of the bag. A portion b' of the bag guide swings away together with the second pusher, and the bag flips over, aided by a bar d which moves with the guide portion b'. The bag thus hangs from its point of attachment to the card. The process is repeated for successive bags to attach them to successive tongued positions on the card. <IMAGE>

Title: Improvements in or relating to beds
IPC: A47C19/22
Filed: 1980-08-05
Abstract: A divan bed has a floor standing base 2 of hollow construction defining a storage space accessible by way of openings 5 having roller shutter doors 6. The length of the shutter doors 6 is greater than that of the openings 5 so that a storage roll 7 created by the opened door is not completely depleted when the door is closed. In this way snagging of the contents of the storage space by the trailing edge of the door when the door is opened is prevented because this edge is protected by one or more turns of the roll that are never unwound. <IMAGE>

The semi-conductor is first cold pressed in a mould to produce a preformed body of the desired shape the pressure being 1000 p.s.i. or more. The body is then placed in a groove shown in the insulator 13. A hot pressing operation is then performed details of which are specified and the assembly is then cooled under pressure to a temperature of about 1000‹F. As the semi-conductor composition tends. to adhere to metal a separator disc of alloy sold under the Registered Trade Mark "Inconel", or of talc the metal disc being coated with graphite is placed between the semi-conductor body and the ram. The insulator and semi-conductor composition may be simultaneously formed. The preformed body may be a disc for covering the entire bottom surface of the insulator. A relatively soft metal washer 19 for example nickel or nickel alloy is interposed between the head 17 and the insulator 13. Washers 25, 35 and 37 are of nickel. The seal between the insulator 13 and the electrode 9 may.be assured by collapsing a small diameter portion 29 of the electrode and the sealing of the insulator to the shell may be assured by collapsing the portion 43 of the shell 3. The insulator 13 is preferably of sintered alumina type material. Specification 746,566 [Group XXXVI] is referred to.

Title: Parallel tube heat exchanger
IPC: F28D7/12
Filed: 1981-11-03
Abstract: A heat exchanger for immersion in pool of primary liquid metal coolant (such as sodium in a nuclear reactor) comprises a bundle of spaced parallel tube assemblies (40). Each assembly comprises three vertical co-axial tubes (1, 3 & 5) supported from tube plates (7, 8 & 9) situated above the pool. The outer tube (3) is closed at its lower end and in operation secondary coolant (which may also be liquid sodium) flows down the inner tube (1) and then up the outer tube which is in heat exchange with the primary coolant. The assembly thus defines flow and counterflow paths for the secondary coolant in successive passes. The intermediate tube (5) defines an annular jacket for insulating gas such as argon which is supplied from a plenum chamber (6). The gas jacket serves to deter heat transfer between successive passes of the secondary coolant. <IMAGE>
