Title: Method and apparatus for the Transfer and Injection Molding of Synthetic Thermosetting and Thermoplastic Resins
Inventor: HULL JOHN L
IPC: B29C45/18
Filed: 1967-12-18
Abstract: 1,166,710. Injection moulding. HULL CORP., and W. T. LA ROSE & ASSOCIATES Inc. 18 Dec., 1967, No. 57476/67. Heading B5A. In the transfer and injection moulding of thermosetting or thermoplastic resin, which may contain glass fibre reinforcement, provided initially in the form of preforms P, the latter pass down a shoot 10 and are fed singly on to rods 18 by the controlled operation of a pair of stop-rods 12<SP>1</SP>, 14<SP>1</SP> operated by pneumatic cylinders. The preform is then pushed up a guide 22 to a pair of rollers 32 on arms 34, 36 by the piston-rod 20<SP>1</SP> of an air cylinder 20, whereby the preform is rotated and heated uniformly by an electronic heater 26. When the preform reaches the desired moulding temperature, i.e. the curing temperature in the case of thermosetting materials, and, in the case of thermoplastic materials, the maximum softening temperature enabling it to be transferred to the mould, the arms 34, 36 are separated and the preform falls to a guide 46 from which it is delivered by a ram 48 to the transfer pot 50 of a closed mould. The latter includes a fixed section 56, with the transfer pot, connected to a stationary heated platen 54, and a movable section connected to a heated platen 58 and urged to mould closed position by an hydraulic cylinder 64. In a modification, instead of the rotatable roller assembly 32, 34, 36, the preform is received in the guide 46 directly from the guide 22 and is rotated by rollers projecting through the guide 46, heated therein, and delivered by the ram to the mould.

Abstract: 1,214,490. Fluid-pressure servomotor systems. ROBERTSHAW CONTROLS CO. Dec.19, 1967 [Dec.19, 1966], No.57681/67. Heading G3P. [Also in Division F2] A pressure regulating valve to control flow from a gas source through an inlet 28, to a burner through an outlet 30 comprises a diaphragm valve 34, see Division F2, closing one side of a chamber 36 which is connected via a passageway 48 with a chamber 26 connected via and on/off valve 20 and bleed pressure regulator 18 to the outlet 30. A bleed passage 44, with a restrictor 46 connects the inlet 28 with the chamber 26. Valve 20 is controlled by a thermal bulb 22. When the space in which the bulb 22 is located has no heat requirement, valve 20 shuts a passage to the regulator and chamber 36 is connected with inlet 28 via passage 44, and the valve 34 is closed by a spring 42. When there is a demand for heat, valve 20 is opened, and chamber 36 is connected with the outlet connection 30, via the regulator 18. The valve is then opened by inlet pressure at 28 until the pressure in the outlet reaches the set point of the regulator 18 whereupon it closes and pressure builds up in chambers 26 and 36 to close the valve 34. To prevent hunting the diaphragm valve 34 is either formed with a diametral rib, Figs.2 to 9, (not shown) or a cavity connecting with the space within its seat, Figs.10, 11, (not shown) which can have diametrally extending hubs, Figs.13, 14, (not shown).

Title: Apparatus for testing rod-like articles having a wrapper and a permeable filler
Inventor: HEITMANN UWE
IPC: A24C5/34
Filed: 1968-12-09
Abstract: 1,244,973. Testing cigarettes. HAUNIWERKE KORBER & CO. K.G. 9 Dec., 1968 [7 Dec., 1967], No. 58483/68. Heading A2C. A device for testing or checking cigarettes comprises a conveyor having holders adapted to support two rows of cigarettes at a uniform pitch, which rows are axially spaced apart, for each row a connector means at one end of the cigarettes for supplying checking air to the cigarettes and a device at the other end of the cigarette to receive said air from the cigarettes and pass the air to an air checking device, wherein the connector means is movable up to and away from the cigarettes. The conveyor may be in the form of a drum 2 shown in partial section in Figure 3. The two rows of cigarettes are position in feed tracks 43 and 43a which are separated by a central ring member 46. These tracks are bounded by ring 26 and terminal ring 48 respectively, these rings embodying bores 50 and 50a through which project sealing members 51 and 51a. Two adjacent members 51 are assembled to form a connector block 52 which is carried on two parallel springs 53, 54 so that the block is movable in the axial direction. In operation, during movement of the drum 2, the block 52 is urged axially inwards by control cam 65 so that the end face of connecting tube 64 is placed against the end face of the cigarette 37 which slides against the end face of the central ring member 46 so that both ends of the cigarettes are sealed. A supply of checking air passes from source 25 through connecting tube 64 into the cigarette, and through a connecting duct into the other end of this cigarette. With the drum so positioned, bore 76 is blocked by a shoe 78. The same actions occur, in the rear part of the drum in respect to cigarette 38. On further movement of the drum, the bore 76 connects with a control slot 79, and connects with an air checking appliance 28 (not shown) which measures the pressure in the cigarette 37. A further feed movement of half a pitch results in bore 76 passing out of the region of control slot 79 thus becoming closed. Simultaneously bore 76a is connected with control slot 79a and the pressure in cigarette 38 is measured in appliance 28. The successive pulses delivered by appliance 28 are separated according to the pulses of the two timing pulse sources 30, 31 (not shown) and supplied in separate paths to air blower valve 89. During these two cycles, the holders move to a rejection region and the block 52 moves back to its initial position. If a fault pulse is received, the air blower valve 89 is activated and passes a jet of air through a nozzle 94 or 94a to eject the faulty cigarette. Fault-free cigarettes are then delivered to a transfer drum and thence to a reversing drum which combines the two rows of cigarettes into one row of the same orientation. The checking device may also comprise pneumatic low pressure control elements, a pneumatic amplifier and a delay unit.

Title: Iamge pick up devices
IPC: H01L27/105
Filed: 1972-12-21
Abstract: 1385282 Image pick-up devices WESTERN ELECTRIC CO Inc 21 Dec 1972 [23 Dec 1971] 59016/72 Heading H1K An image pick-up device comprises a wafer of photoconductive material, means for producing an array of potential wells at one face of the wafer in which optically generated charge carriers are stored, and at least one charge transfer channel at the opposite face of the wafer to which the stored carriers can be transferred in operation. A typical device consists of a 15Á thick N type wafer, e.g. of silicon having on one surface a layer of silicon oxide covered by a transparent electrode layer of gold or tin oxide. An array of potential wells is provided by constructing the oxide, layer with an array of thinner portions or forming an array of zones of immobile charge, e.g. in the oxide or preferably as P type zones in the silicon, beneath the electrode layer. In operation, with the electrode negative, minority carriers generated in the silicon by light incident on the electrode collect in the potential wells and are periodically transferred to charge transfer channels on the opposite wafer face which may be of the bucket brigade (Fig. 3, not shown) or charge-coupled (Figs. 1 and 4, not shown) type. Transfer is effected by appropriately biasing the field electrodes of the channels to cause diffusion of the carriers, in which case the wafer should be thinner than the diffusion length, or to provide depletion layers extending to the potential wells to produce a drift field, e.g. when using a wafer of GaAs, to speed up transfer. The wells generally form a co-ordinate matrix and are preferably aligned with field electrodes of the channels, though there may be more wells than field electrodes in which case the optical resolution is determined by the spacing of the latter. To facilitate mounting the wafer may have a thicker periphery and be attached by resin or rubber to a ceramic substrate carrying a suitable pattern of conductors. After transfer of the stored charge recharging of the wells continues while the transferred charge is read out by applying scanning voltages to the field electrodes of the channel to transfer it to a detector. The matrix may be scanned a row or a column at a time as described with reference to Figs. 5 and 6 respectively (not shown). Successful operation at low light levels can be achieved by biasing so that impact ionization of the light generated carriers occurs.
