Title: Improvements in and relating to pneumatic pickups for measuring gap widths
Inventor: WIEMER ARTHUR
IPC: G01B13/12
Filed: 1965-09-14
Abstract: 1,113,238. Pneumatic gauges. DEUTSCHE AKADEMIE DER WISSENSCHAFTEN ZU BERLIN. Sept. 14, 1965, No. 39233/65. Heading G1M. A pneumatic pick-up 2 for measuring gap widths 5 is provided with an elastic seal 4 which defines a measuring chamber 8, the gap width being the only variable dimension of the chamber. Stops 7 and guide elements 13 facilitate placing of the pick-up 2. In a modification, for use with wider gaps, the gap is divided by a plate arranged so that the direction of air-flow is only along one side of the plate, perforations being provided for pressure equalization. A further modification is described for use with angled gaps.

Title: Method and apparatus for support and cooling of shell moulds
IPC: B22C23/00
Filed: 1960-11-16
Abstract: 893,408. Casting-machines; cooling moulds. CARTER, R. T. Nov. 16, 1960 [Dec. 18, 1959], No. 39342/60. Class 83 (1). Shell moulds are supported and cooled by placing them on a particulate bed, before or after pouring, fluidizing the bed by applying pressure, thus permitting the mould to sink therein, and then removing the pressure so that the particles closely surround the mould. A series of containers 10 are mounted on a turntable and each comprises an upper compartment 14 containing particulate material such as iron grit or zircon sand separated from a lower compartment 16 by an air-permeable membrane 18. Moulds 62 are fed to the containers 10 in succession from a conveyer 60 and each is poured at a station 64 while supported on the bed 34. A cam member 56 then opens a valve 20 supplying pressure air to the compartment 16 and fluidizing the bed 34 so that the mould sinks therein. As rotation of the table continues the valve 20 closes and the particles settle around the mould, a valve 28 being opened by a cam 30 to exhaust the lower compartment. After the cooling stretch, valve 20 is reopened by a cam 58, fluidizing the bed 34 so that the mould may be removed to a conveyer 66. The bed remains fluidized to cool the particles until just before it reaches the conveyer 60 for reception of another mould. The mould may be differentially cooled by allowing it to sink only partly into the bed, or by having the bed made up of layers of different materials.

The time taken before a hole is produced in fabric 4 by fibre fusion caused by a 2 cal/cm<SP>2</SP>/sec., heat flux due to infra-red lamps 1 and gas burners 2 is measured from the opening of water cooled steel shutter 6. The heat flux is measured by calorimeter 8.  To determine the flame strength a known weight is supported by one end of a 1 inch wide vertical fabric strip suspended at its upper end. A heat flux of 2 cal/cm<SP>2</SP>/sec. is directed through a 2¢ inch high by 1 inch wide aperture in a steel plate behind which hangs the test fabric strip. The maximum load that the fabric will support for 10 seconds heat flux is determined and divided by the total denier of all the yarns running in the vertical direction of the strip.

Abstract: 1,172,112. Coating-resistors. ELECTRA MFG. CO. 1 Sept., 1967 [21 Sept., 1966], No. 40166/67. Heading B2L. A machine for coating cylindrical electrical resistors removes the resistors from a storage area 14, completely covers them with an excess of coating by a wheel 101, removes the excess with a wheel 148 and then transports the coated resistors to a second storage area 15. The resistors are carried in trays 17 which are moved by a chain conveyor 18. During movement by the conveyor 18 the resistors are first aligned by passing between jaws the distance between which has been previously adjusted, they are then heated by infra-red radiation and then pass tangentially to the coating wheel 101 which has a trough-like circumference and carries coating material from a tray 103. Excess coating is wiped off with a wiper blade before coming into contact with the resistors. During coating the resistors are rotated by rubber wheels 118 and fixed pads which contact their lead wires. The resistors then pass on to the excess coating removal wheel 148 which has parts of its circumference which conform to the required size of the resistors. Excess is removed by this wheel as the resistors are rotated against it by rubber covered wheels 139. The resistors are rotated after this continuously as they progress by bands 160 to produce an even finish.

Title: Improvements in or relating to transistor electrical inverter systems
IPC: H02M7/5383
Filed: 1958-12-17
Abstract: 863,658. Transistor inverter circuits. WESTINGHOUSE ELECTRIC CORPORATION. Dec. 17, 1958 [Dec. 31, 1957], No. 40692/58. Class 40(6) [Also in Group XXXV] An inverter of the type comprising two alternately conductive transistors which are connected to a feedback transformer so as to reverse conduction each time the transformer saturates, has a capacitor connected in circuit with the transformer to form a resonant circuit which maintains the saturation condition for a time after one transistor is cut-off and thereafter reverses the transformer current flow so as to render the other transistor conducting. Fig. 1 shows a transistor inverter comprising two transistors which conduct alternately and so provide a high voltage to a capacitive load 9a in the form of an electro-illuminescent device. When transistor 33a becomes conducting the current through the transistor and the upper half of the primary winding of a transformer 11a commences to increase. This induces a voltage in the secondary winding 27a through which charges the load 9a and causes an increase in current to flow through the primary winding 53a of transformer 49a. This increasing current induces a voltage in the secondary winding to maintain transistor 33a conducting until the transformer 49a saturates whereupon the secondary voltage falls to zero and transistor 33a cuts off. The load 9a then commences to discharge resonantly through an inductor 83 and the primary winding 53a maintaining both transistors cut-off until the curent through the resonant circuit reverses, whereupon a voltage is induced through, the secondary winding 69a which causes transistor 35a to conduct so that the voltage applied to the load is reversed. The output voltage is of sine wave form but if inductor 83 is removed a square wave output is produced (Fig. 1, not shown). When the load is of inductive impedance it is placed in the position of inductor 83 and a capacitor replaces load 9a.

As described, the recording of the bits of a word and the production of stepping pulses to drive the motor are both controlled by a clock pulse generator which is disabled after it has delivered the same number of pulses as the number of bits in a word. A final stepping pulse is then applied to the motor after a longer interval than normal in order to reduce hunting. During playback, detection of the end of the recorded word causes the tape to be stopped in substantially the same position as during recording.
