Title: Improvements in and relating to switching arrangements for controlling the duration of operation of electrical apparatus
IPC: B23K11/24
Filed: 1934-07-23
Abstract: 435,949. Switching systems for resistance welding. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London. July 23, 1934, No. 21506. Convention date, July 22, 1933. [Class 38 (iv)] [See also Group XXXVII] A timing apparatus, particularly for completing the circuit of a welding transformer 5 for a pre-determined short time, comprises two self-starting synchronous motors 29, 30 designed to turn a shaft 33 in opposite directions. The shaft 33 is connected by gearing 34 to a shaft 24 which is thus made to turn one revolution per second. An arm 22 is fixed to the shaft 24 which adjustably carries an arm 23. A switch arm 21 movable between stops 27, 28, and normally biassed towards the latter, extends between the ends of arms, 22, 23 and so, in conjunction with stops 27. 28, constitutes a stop for the arms 22, 23. Before the commencement of a welding operation the parts are in the position shown. The circuit breaker 16 is closed and motor 30 is energized from the mains 3, 4, through contacts 41 of relay 42 to move arm 23 against switch arm 21, causing it to engage contact 28. On depressing push button 10, electromagnetic switch 8 is energized to close welding circuit at 7. A hold-on circuit for the switch 8 is closed at 18 which also closes a circuit through conductors 19, 11, 46 and 17 to energize relay 42 and de-energize motor 30. Motor 29 is also energized through conductors 19, 11, 37, 38, 39, 17 and begins to turn the shaft 24 counterclockwise until, after a period depending on the angular separation of the arms 22, 23, the arm 22 engages the arm 21 to break the circuit at contact 28. This de-energizes switch 8 to break the welding circuit at 7. The circuit is broken at 18 which de-energizes motor 29 and relay 42. Motor 30 is thus re-energized and turns the shaft 24 clockwise until arm 23 pushes arm 21 into engagement with contact 28 and the apparatus is reset ready for another depression of button 10. The arm 22 is arranged on spindle 24 in such manner that circuit is broken at 7 at the zero of the voltage cycle. A modification is described in which the switch arm 21 is influenced by a dead-centre spring toggle. This prevents a fresh operation being initiated before the arm 23 has run its full course in the resetting direction. Specification 420,042, [Group XXXVII], is referred to.

Abstract: 1,148,130. Branding carcases. SLAGTERIERNES FAELLESINDKOBSFORENING. 10 May, 1967 [13 May, 1966], No. 21637/67. Heading A1X. Apparatus for branding carcases comprises at least one pair of guide members 26, 28 arranged in a vertical plane and along which branding rollers are moved, means for resiliently forcing the rollers, into contact with the carcase, and an endless chain 80 associated with each pair of guide members and connected to each branding roller whereby the rollers are moved so that one roller will be in its uppermost position on its guide member when the other is in its lowest position. Each guide member 26 or 28 is pivoted on a vertical shaft 30, 32 and carries a slidable bushing 64 which has a plate 66 shielding a gas-heated branding roller, the bushing being connected by a telescopic link 72 to a carriage 76 movable on the associated vertical shaft and forming a link in the chain 80. An electric motor 100 drives the chain and is started by means of a switch operated by the guide members 26, 28 as they move inwardly to contact the carcase and stopped by a switch operated by one of the carriages 76 as it reaches an extreme position. The guide members are located in a box-like framework, members 26, 28 being provided on each side of the framework. Shafts 30, 32 carry wheels 38, 42 which run on crossmembers 62, 56 which are moved backwards and forwards by means of cranks 48 located on a shaft 44 driven by a further motor (not shown) thereby causing guide members 26, 28 to move inwardly, which movement is aided by springs 34 on the shafts 30, 32. The carcases are suspended from a conveyer for movement through the apparatus.

Title: Modified acrolein-pentaerythritol resins and a process for their preparation
IPC: C08G4/00
Filed: 1957-07-09
Abstract: Liquid A-stage condensates formed by reacting 1.3-1.9 mols of acrolein with 1 mol. of pentaerythritol in the presence of an acid catalyst are modified by the addition of either 2-25% of 3,9-divinylspirobi-(m-dioxane), viz.: <FORM:0827032/IV (a)/1> or 2-15% of acrolein dimer, viz.: <FORM:0827032/IV (a)/2> the proportions being by weight of the total composition.  The A-stage condensates are prepared at 60-100 DEG  C. and the volatiles are then stripped off to produce condensates of low (5000-25,000 c.p.s. at 40 DEG  C.) or high viscosity (25,000-500,000 c.p.s. at 40 DEG  C.).  If HCl is used as the initial catalyst, the modifiers are normally added with such curing catalysts as sulphuric, toluene sulphonic, benzene sulphonic, phosphoric or mixed alkane-sulphonic (primarily ethanebut also containing methane- and propane-) acids, stannic, aluminium or ferric chloride, boron trifluoride, or titanium tetrachloride. If, on the other hand, another acid is used as the initial catalyst, e.g. sulphuric, benzene sulphonic, or toluene sulphonic, that acid will itself function as the curing catalyst; or alternatively, it may be neutralized with sodium carbonate or acetate, and an appropriate curing catalyst added later.  In either case curing takes place at 50-200 DEG  C.  As the spirobi compound melts at about 43 DEG  C. it is preferably added at temperatures of 45 DEG  C. or higher. Uses.-Display signs, ornaments, fixtures, dentures, sealing and potting electrical components, glass cloth laminates.  Specifications 720,954, [Group XIV], and 822,668 are referred to.

In a klystron, the active surface of the anode or target electrode is increased in area, by the provision thereon of grooves divided into two or three groups angularly disposed relative to one another to form pyramidal denticles on the surface. This allows greater amounts of electron bombardment before surface melting of the anode occurs. Preferably the anode is such that the base lines of the denticles are approximately normal to the direction 6 of electron flux at the point of impact. For example, the denticular surface 2 may be arranged step-wise round the interior of an anode block 1. The denticles are of millimetric dimensions, and the external surface of the anode may be cooled by known methods.

Title: Discriminating zero crossing detection circuit

Filed: 1973-05-09
Abstract: 1369390 Pulse shaping and discriminating circuits INTERNATIONAL BUSINESS MACHINES CORP 9 May 1973 [26 May 1972] 22057/73 Heading H3T [Also in Division G4] False operation by noise of a zero-crossing detector is reduced by allowing the zero-crossing to switch a bi-stable circuit only if it has previously been set by the signal exceeding a threshold value determined by the peak level of the signals. In Fig. 3 a capacitor C is charged to the peak value of a signal at 10 and the charge slowly decays. If the next signal exceeds the level to which it has decayed, transistor T5 conducts, recharges the capacitor and via T4, sets a bi-stable circuit T6, T7. When the signal passes through zero, a zero-crossing detector T1, T2 switches over and transistor T1 resets the bi-stable circuit. If a noise pulse is received at a lower level than the value to which capacitor has discharged, T5 remains non-conductive and the bi-stable circuit is not set. The circuit is applicable to signals received from a magnetic storage disc.
