Title: Improvements in multiple-purpose vibrator power supply systems
IPC: H02M3/42
Filed: 1945-03-03
Abstract: 591,290. Converting. PLESSEY CO., Ltd. March 3, 1945, No. 5343. Convention date, March 9, 1944. [Class 38 (ii)] A system for supplying currents at different voltages for devices such as dry shavers and radio receivers from a L.T. battery comprises a vibratory interrupter and a step-up transformer with means for connecting the appropriate voltage to one or other of the output circuits. A.C. is developed in the secondary 12 of a transformer 10 which has a primary 11, with its two ends connected to contacts 13, 14 of an interrupter 15 which are engaged by an earthed vibrator 16, and a centre-tap connected through main switch 42 to a battery 18, whereby impulses pass through the halves of the primary 11 in the normal manner. When the simultaneously operated switches 24, 25, 26, 27, 35 are in the positions shown in Fig. 1, lower voltage taps on the secondary 12 are connected by switches 25, 26 to a socket 34 from which A.C. may be taken to a dry shaver. In the other position of the switches, the closure of switches 24, 27 brings into use vibratory rectifier contacts 29, 31 connected to higher voltage taps on secondary 12, so that a H.T. D.C. supply is available at the secondary centretap for connection through a filter circuit to the valve anodes of a radio receiver, while the closure of switch 35 energizes the filament heaters. In one modification, the ganged switches and socket 34 are combined in a jack switch into which the dry shaver plug may be inserted to make connection with the L.T. A.C. supply and at the same time disconnect the radio receiver supply, Fig. 2 (not shown). A similar arrangement with the jack switch, but in which the rectifier contacts 29, 31 are replaced by a rectifier valve, is also described, Fig. 5 (not shown). Two further modifications are described in which the two outputs are obtained from the centre-tap of the secondary 12, change-over switches being provided to connect different secondary taps to the rectifier. In one case,'Fig. 3 (not shown), the apparatus has the two rectifier contacts and dry shaver socket as shown in Fig. 1 and in the other case a valve rectifier and jack switch are described, Fig. 6 (not shown). In the modification shown in Fig. 4, D.C. 'is supplied both to the radio receiver and also to the socket 34, the voltage difference being obtained by the insertion of a resistance 75 in the connection to the primary centre-tap. When a two-pole switch 70 is in the upper closed position, battery 18 is connected through contacts 72, 74 to the transformer and valve filament'heaters respectively, while in the lower closed position these circuits are broken and resistance 75 is connected to the transformer. The voltage to socket 34 may also be lowered by a resistance 76 in the output side.

IPC: C08L77/06
Filed: 1968-02-02
Abstract: 1,201,713. Transfers. POLYMARK Ltd. 23 Jan., 1969 [2 Feb., 1968], No. 5539/68. Heading B6C.  A heat transfer comprises an inked design on a layer of a heat curing film-forming resin system in the presence of blocked cross-linking groups and under acid conditions, said resin being heat-curable to form an inert, insoluble and wear-resistant marking on said surface. The film-forming resin system used in the present invention comprises (1) a film-forming heat-sealable resin bearing functional groups, such as hydroxyl, amino, amido or carboxyl groups, (2) cross-linking groups which are blocked by substitution such as methoxymethyl or ethoxy-methyl groups such groups containing a substituted methylol group and (3) if the resin itself does not have acidic properties, curing agents are present which are organic acids or acid-yielding substances which acids or substances are inactive at normal room temperatures but become effective to promote curing of the resin at the higher temperatures used for heat-sealing the marking element to a surface to be marked. Transfers of this kind are applied under heat and pressure to the surface to be marked with the continuous layer of the resin system in immediate contact with the surface to be marked. The continuous layer becomes permanently bonded to the article and, due to the release properties of the temporary support the latter may then be removed leaving the transfer in place.

Abstract: 778,969. Step-by-step conveyers. UDYLITE RESEARCH CORPORATION. Feb. 25, 1955 [March 17, 1954], No. 5758/55. Class 78 (1). An apparatus for the liquid treatment of articles comprises a tank 16, means for raising and lowering a work-carrier 71 out of and into the tank 16, means for rocking the carrier 71, and means for progressively reducing the amplitude of the rocking movement as the carrier 71 is raised. A number of carriers 71 pass in succession through tanks 15, 16 and move on rails 18<SP>1</SP>, 32 which are supported respectively on brackets 25, 25<SP>1</SP> pivoted to lugs 26, 26<SP>1</SP> on arms 17, 31, of which 31 is connected to a chassis 5 which is movable up and down by chains on pulleys 11 to withdraw articles from and immerse them in the tank 16. The arm 17 is secured to fixed bars 2, the rails 18<SP>1</SP> being thus not raisable. Both rails 32 and 18<SP>1</SP> are rocked as follows: a motor 43 drives a pulley 45 connected by a chain 46 to a pulley 42 on a shaft 40 on which are eccentrically mounted two discs .50, Fig. 3. One disc 50 is connected through members 52 ... 54 to a rod 58 connected to an arm 30 of the bracket 25, which is therefore rocked on rotation of the disc 50. Similarly, the other disc 50 is connected by member 52<SP>1</SP> to a stop 66 pivotally joined to an arm 62 which pivots at 63 on a fixed strap 60. An arm 30<SP>1</SP> on the bracket 25<SP>1</SP> is pivotally connected at 69 to a rod 68 which is joined to a block 64 which is free to move up and down the arm 62, a notch 70 in the block 64 engaging the pivot 63 in the top position of the block 64. By this means, the amplitude of the oscillations imparted to the bracket 25<SP>1</SP> through the members 66, 62, 64, 68 is progressively diminished to zero as the block 64 rides up the arm 62 when the carrier 71, bracket 25<SP>1</SP> and rail 32 are raised by the chassis 5. The carriers 71 are moved along the rails 181, 32 by slidable members 83, 83<SP>1</SP> respectively which have pivoted arms which engage blocks 77 on the carriers 71 in one direction, but ride over the blocks 77 in the opposite direction. The means for moving the members 83, 831 are not shown. Each carrier 71 has two beams 73 each carrying a bracket 74 which support a bar 75 from which articles are suspended. Rail sections are included which are neither raisable nor rockable.
