Filed: 1972-08-16
Abstract: 1368664 Hydrostatic transmissions ROBERT BOSCH GmbH 16 Aug 1972 [20 Aug 1971] 38194/72 Heading F2D [Also in Division G3] Reversible variable displacement pump 2 has a swashplate 3 adjusted by servopistons 13, 19 in cylinders 14, 21 supplied with fluid from auxiliary pump 50 via valve 25 which, in position I, admits the fluid to cylinder 17 to control delivery of pump 2 in one direction and, in position II, admits the fluid to cylinder 21 to control delivery in the opposite direction. Valve 25 is controlled by lever 34 via follow-up linkage 30-33, lever 34 being linked to lever 59 which thereby opens one of valves 55, 56, according to the delivery direction of pump 2, so that fluid from pump 50 is directed to line 63 or 64 to be available for admission to cylinder 39 or 42 to act on over-ride piston 36 or 37 when valve 45 shifts to position II in response to excess pressure drop across restrictor 51 indicating excess speed of pump 50 and hence pump 2. Pistons 36 or 37 thereby limit torque input to pump 2 to prevent its drive engine from stalling. Restrictor 51 is by-passed by check valve 51<SP>11</SP> which opens at a pressure drop exceeding that required to operate valve 45. When valve 25 is in position I, valve 7 responsive to excess delivery rate of pump 2 can relieve pressure in cylinder 14 to reduce the swashplate angle. When pump 2 is employed in a hydrostatic transmission, it connects at 23 with a return line from a motor, and pump 50 supplies fluid to the return line.

Title: Improvements in or relating to semiconductor devices
IPC: H01L29/00
Filed: 1956-12-18
Abstract: 851,075. Semi-conductor devices. TELEFUNKEN G.m.b.H. Dec. 18, 1956 [Dec. 24, 1955], No. 38539/56. Class 37 In a semi-conductor device comprising a body of semi-conductor material with a minority carrier emitter and opposite to it a collector, a significant impurity gradient other than zero is provided throughout the entire body in a plane perpendicular to the average direction of the minority carrier paths to render these paths parallel. In the alloy junction transistor shown in Fig. 1, the amount of excess donor impurity decreases continuously as shown from the centre of the body to the circular base connection 8. The effect of the impurity gradient is to provide a focussing electric field which renders the transit times of minority carriers between the emitter and collector more uniform. The semi-conductor base body of a point contact diode may be differentially doped in the same manner. Suitably doped bodies may be formed by diffusion of impurities from the surface. Specification 721,671 is referred to.

Abstract: 1318109 Thermoelectric devices TOYOTA CHUO KENKYUSHO KK 12 Aug 1970 [28 Feb 1970] 38943/70 Heading H1K An instrument for measuring rates of gas flow is based on two thermocouples connected in series opposition, one junction being in close proximity to the midpoint of a constant currentfed heater wire and thermally (and electrically) connected thereto and the second junction being placed as close to the first junction as is possible without it being affected by the heater. In embodiments the supports a, b for the "Nichrome" (Trade Mark) heater wire I may be phosphor-bronze rods or hollow stainless steel tubes, the ends of the rods or tubes being bevelled so that the heater wire may be easily welded thereto. The wire element c of "Alumel" (Trade Mark) forms junctions with elements d and e of chromel. Elements d and e may both be of wire-form and may be taken directly or via supporting rods or tubes to a 4-pole plug constituted with the heater supports a, b, the four ends being mechanically joined by "Araldite" (Trade Mark) at the plug. The supports for the thermocouple elements d, e may be of phosphor-bronze but if they are of chromel the wire element d may be replaced by its support. Various constructions are shown which avoid the connection of c and e to two different points of the heater wire I by making the junction between the two elements at a small distance from the connection between one of them and the heater wire. The output of the unit may be fed to a meter through a linearizing amplifier. Alternative indicators are C.R.T.s or chart recorders. The unit may be used for measuring the air flow through radiators or for investigating the flow distribution in the outlets of car heaters or defrosters.

Title: Glass-ceramic body and method of making it
IPC: C03C4/06
Filed: 1963-10-03
Abstract: <P.1> A semi-crystalline glass-ceramic body is made by exposing an article of glass containing a photo-sensitive metal to short-wave radiation, followed by heating in turn to 560-620 DEG  C. for a time sufficient to initiate formation of sub-microscopic nuclei of photo-sensitive metal, to 625-670 DEG  C. to opacify the glass, to 750-850 DEG  C. to obtain the desired crystallization, and finally cooling to room temperature.  The glass consists by weight of 7-11% Li2O, 1-2% Na2O, 3-5% K2O, 3-4% ZnO, 12-16% Al2O3, 62-74% SiO2, and, as photo-sensitive substances, 0.001-0.03% Au, 0.001-0.3% Ag, calculated as AgCl, or 0.001-1% Cu, calculated as Cu2O. 0.0118% CeO2, to increase photosensitivity, and 0.40% Sb2O3, as fining agent, may be present.  Short-wave radiation is of wavelength 2500-4000 <\>rA. In Fig. 3 is shown an example of the variation of temperature with time, the solid line representing a typical treatment, and the dotted areas indicating a range of treatments suitable for a particular glass.  The glass-ceramic body contains 3 major phases, viz. (1) lithium metasilicate, (2) b -spondumene solid solution, and (3) "silica O," i.e. a b -eucryptite-b -quartz solid solution phase or a series of isostructural materials of which b -eucryptite and b -quartz are typical end materials.  The lithium metasilicate is the predominant crystalline phase. To form the original glass body, the batches are melted at 1450 DEG  C. and are then cast into a steel mould and pressed, and then reheated at 400 DEG  C.  To yield a shape of desired configuration, sculpturing may be undertaken before final heat-treatment: thus, a pattern impervious to short-wave radiation is placed on the original glass body, and the assembly is irradiated, after which the nucleation and growth steps are performed.  The resultant lithium metasilicate may be etched with hydrofluoric acid, leaving a body with the desired sculpturing.  This glass sculptured body may be converted to a glass-ceramic body by heating to 900-950 DEG  C., or, in a preferred method, the sculptured glass body is again exposed to short - wave radiation without the masking pattern, and is then subjected again to nucleation and growth steps, after which it is passed to the final heat treatment.  The sculptured glass-ceramic bodies may be used for electron tube spacers, printed circuit boards, and substrates for thin-film semi-conductors, e.g. by sealing to Si or Ge. Specifications 699,397 and 752,243 are referred to.
