Title: A new or improved system for starting up turbine type starters for gas turbines
Inventor: TROWBRIDGE DAVID ROY
IPC: F02C7/277
Filed: 1952-02-20
Abstract: 732,113. Gas turbines. PLESSEY CO., Ltd. Feb. 16, 1953 [Feb. 20, 1952], No. 4437/52. Class 110(3). A gas turbine starter motor has a cartridge to supply motive power for the initial starting of the starter turbine and for a separate turbine driving a fuel pump for supplying liquid fuel to a combustion chamber feeding the starter turbine. A cartridge 1 is connected by a passage 2 to a combustion chamber and turbine 3, which is connected through mechanism 4 to the engine being started. A passage 5 connects the combustion chamber to a turbine driven pump 6 which draws fuel from a tank 7 and discharges it through a shut-off valve 10 and control valve 13 to the combustion chamber. When the switch 17 is closed, the valve 10 is operated to open the passage 11 and close the passage 12 leading back to the fuel tank. The switch 18 is now closed and the cartridge 20 detonated. Gases then pass to the combustion chamber and starter turbine 3 for the initial starting of the starter turbine. Some of these gases pass through the combustion chamber 3 to the turbine driven pump 6. The pump then supplies fuel to the combustion chamber which is ignited by the hot gases from the cartridge. The spring-loaded control valve 13 regulates the fuel supply. After the initial starting, the pump 6 is supplied with motive fiuid from the combustion chamber. To shut down, the switch '17 is opened to cause the valve 10 to open passage 12 and shut passage 11.

Title: Process and apparatus for the electrolytic polishing of metal
IPC: C25F7/00
Filed: 1959-02-09
Abstract: 862,381. Polishing metals electrolytically. HEYES, J., and FISCHER, W. Feb. 9, 1959 [Feb. 11, 1958], No. 4461/59. Class 41. In the electrolytic polishing of metals, especially iron and aluminium, using as electrolyte a mixture of acetic acid and perchloric acid or a perchlorate, the surface of the electrolyte is covered with a layer of paraffin oil, whereby acid fumes are prevented. A suitable apparatus comprises a vessel A divided by a partition B to form two chambers CE both containing the electrolyte and a layer of oil floating thereon. To remove the layer of oil from the treatment chamber C when articles are to be inserted or removed, electrolyte is pumped from chamber E to chamber C to raise the level of the oil layer a little above the partition B, and removal thereof is completed by electrolyte passing to the surface through a spray pipe H. When the oil layer is to be restored, electrolyte is pumped into chamber E and the oil layer D flows over the partition B to form the layer D 1.

Title: Method of producing flexible textured thermoplastics sheets
Inventor: SCHNABEL MAX
IPC: D06C7/02
Filed: 1973-01-29
Abstract: 1374223 Finishing fabrics REHAU PLASTIKS GmbH 29 Jan 1973 4466/73 Heading D1S An impermeable sheet is produced by forming a fabric from synthetic thermoplastic filaments and consolidating the fabric by the application of heat and pressure. Preferably synthetic filaments, natural fibre threads and/or metal filaments are coated with thermoplastic polymer by extrusion or dipping and formed into a fabric by weaving, warp knitting, or braiding. The fabric is consolidated by hotcalendering or by infra-red heating followed by pressing with a plate press or a calender and then cooled. A continuous impervious thermoplastics layer is formed on one or both surfaces. The coating of the filaments is polyethylene made by the high or low pressure process, polypropylene, polyvinyl chloride ethylene-vinyl acetate copolymer or polyamide. Decorative patterns may be produced by using twill, herring-bone, sculptured or fancy weaves or by using filaments some of which are coated with polymer of one colour and others coated with polymer of a second colour. A patterned variation of mechanical properties is obtained by varying the spacing between filaments, introducing additional filaments such as metal wires (which can act as electrical conductors) and making use of filaments whose coatings have different degrees of hardness, e.g. softer warps. Some of the filaments may be coated with foam plastics.

Title: Improvement of the Electrode Lead-Out Structure of a Semiconductor Device
IPC: H01L23/057
Filed: 1969-01-27
Abstract: 1,191,093. Semi-conductor devices. HITACHI Ltd. 27 Jan., 1969 [29 Jan., 1968], No. 4479/69. Heading H1K. A semi-conductor circuit chip is mounted on a metal plate carried by an insulating substrate on which are disposed a plurality of external leads which extend beyond its periphery. An electrical connection is made between an area of the plate not underlying the chip and one of the leads, and other connections between the remaining leads and electrodes on the top face of the chip. In one example the chip contains a number of silicon IGFETS the diffused source regions of which are short-circuited to the substrate at the upper face so that voltage can be supplied to them through the thickness of the wafer from the plate. Normally the chip 6 (Fig. 2) is gold alloyed to the plate 3 which is then attached to substrate 1 via a layer 2 of low-melting glass. Typically, the metal plate is of nickel or iron-nickel-cobalt alloy, the leads of similar alloy faced with aluminium and the wires 7 of aluminium. In this case an aluminium layer 5 is provided on the plate to facilitate thermocompression bonding of the wires. If gold wires are used layer 5 may be an extension of the gold-bonding layer 4. A plate with a number of layers 4 and 5 may be formed by depositing aluminium over the plate, photoresist etching to restrict it to certain areas, depositing gold on the remaining areas, forming grooves to separate the two metals and then stamping to subdivide the plate. If after etching the assembly is heated the photoresist will flow over the sides of the islands of aluminium and thus isolate them from the gold so that the grooves appear on removal of the photo-resist.

Title: Improvements in time controlled electric signalling or controlling systems
IPC: G04C21/30
Filed: 1945-02-22
Abstract: 602,462. Switching systems. TELEPHONE RENTALS, Ltd., WILDING, F. A., and DAVIS, F. W. Feb. 22, 1945, No. 4485. [Class 38 (iv)] [Also in Group XXXVIII] An electric signalling or controlling system includes a plurality of " signal " selectors each adapted to select the successive signals of a different programme, a " programme " selector, and " signaltime selectors, with associated circuit arrangements so that a selected signal is given only at a selected time in a selected programme period. The signal may be the switching on of apparatus. In the preferred embodiment described, eight-bank, twenty-five contact uni-selectors are used. The programme period is one day, and four different programmes of signals are provided in a seven-day period at levels SS1 and SS5, SS2 and SS6, SS3 and SS7, SS4 and SS8 of the signal switch. Any of twenty-four signals can be given at any minute of a twentyfour hour programme period. Short current impulses are delivered by any known means to relay A (Fig. 1) to step the minute switch MS once a minute. Once per revolution (30 minutes) the wiper of lever MS2 of the minute switch drives the half-hour switch HS one step via drive magnet HS, DM, and this in turn via level HS1 steps the day switch DS once a day over seven contacts which are multipled three times. It is arranged that spare contacts on all switches cause rapid selfdrive of the switches. Suppose a signal is required at minute m in h half-hour of d day. Level DS2 (Fig. 2) of the day switch selects at contact d the level of the signal switch corresponding to the programme for day d, say SS5. A signal contact of SS5 is jumpered at frame E to the appropriate contact m of the minute switch, the wiper of which is connected to the wiper of the half-hour switch. Level DS1 of the day switch selects a corresponding signal switch level SS1, a contact of which is jumpered at frame F to the appropriate contact h of the half-hour switch. Thus, at d day, m minute, in h half-hour, a circuit is established between the earth on wiper DS2 and the battery on wiper DS1 to operate relay B. The charge on condenser EC then operates relay C via contact b and initiates the required signal. The duration of the signal is dependent upon the capacity of the condenser EC and the characteristics of the relay C. At the inception of the next (m+1) minute pulse, the signal switch is stepped via contact a2 and drive magnet SS, DM, thus breaking the circuit set up above. Various arrangements of uni-selectors are described, varying the programme repeat period, the number of programmes, the number of signals and the unit time interval. One or more banks of the signal switch can be used to determine the nature and distribution of the selected signal (Figs. 7, 7a and 7c, not shown), these arrangements necessitating a reduction in the number of selectable minutes in a programme period.
