Title: Means for coupling through flow appliances in service and installation pipe lines
IPC: G01F15/18
Filed: 1956-12-19
Abstract: 816,181. Pipe couplings. KROMSCHRODER A. G., G. Dec. 19, 1956 [Dec. 19, 1955, Dec. 21, 1955], No. 38678/56. Class 99(1). In an adaptor piece 1 having a coaxial inlet 2 and outlet 7 for connecting service and installation pipe lines to a through flow appliance, e.g. a gas meter, Fig. 1, the coaxial inlet and outlet registers with the coaxial inlet and outlet 5, 8 of the appliance so that the inner of the appliance conduits is coupled to the inner tube of the adaptor to permit relative axial movement therebetween. The inner tubular part 7 of the adaptor projects beyond the end of the outer tubular part 2 and is provided by a large mouth 7a which is adapted to pass over the inner tubular part 8 of the appliance with a compressed packing ring 9 to provide a telescopic joint so that a stress-free mounting on the inner mechanism is ensured. A union nut 4 screwed on to the adaptor couples it to the appliance of which the outer tubular part 5 is soldered to the casing 6 and the joint is sealed by a packing ring 3 retained in position by a ring 14. A baffle plate 11 spaced from the casing 6 by members 10 prevents the entering gases from impinging directly on the mechanism below the inlet formed by members 5, 8. In modifications, Fig. 2 (not shown), the inner part 7 of the adaptor is connected to the outlet 8 of the appliance by a flexible tube or bellows secured at each end by circlips. Fig. 3 shows the end of the part 7 of the adaptor ending in the same plane as the end of the outer tubular part 2 but the inner part 8 of the appliance projects beyond the end of part 5 to engage telescopically as shown. The parts are connected by an internally threaded sleeve nut 15 which has two internal threaded parts but of different pitch and internal diameter so that when tightened the parts 2, 5 are forced together against the sealing ring 3, the use of the sleeve nut allowing a reduction in height of tubular part 5. In Figs. 4 and 5 (not shown), the inner conduit of adaptor and appliance are as shown in Fig. 1, but the outer tubular part of the adaptor fits directly in an aperture in the appliance casing to which it is connected by bolts soldered to the casing and passing through circumferentially spaced arcuate slots in a flange formed on the adaptor. The casing to which the bolts are attached is reinforced by a ring soldered to it, the slots permitting limited orientation of the appliance and a packing ring is inserted between the flange and the casing. To permit complete orientation of the appliance, the slots are omitted and the bolts secured to washers which grip the adaptor flange on its outer periphery.

Title: Improvements in or relating to transistors
IPC: H01L29/00
Filed: 1956-12-31
Abstract: 862,839. Transistors. MINNEAPOLISHONEYWELL REGULATOR CO. Dec. 31, 1956 [Dec. 29, 1955], No. 39630/56. Class 37. In a semi-conductor device comprising a base body of one conductivity type with two zones of the opposite conductivity type formed on its opposed surfaces and a pair of ohmic electrodes disposed on opposite sides of the region between the said zones the configuration of the zones and electrodes is such that no path exists through the body between the ohmic electrodes which does not pass through the region between the zones. In one embodiment (Fig. 2) annular zones 12a, 13a of P-type material are formed in the surface of a monocrystalline body 16 of 4-6 ohm. cm. N-type germanium by fusing toroidal blanks 12, 13 of an alloy of 95% indium and 5% germanium to it in successive heat treatments each comprising heating for 1 minute at 1025‹ F., rapidly cooling to 850‹ F. and then cooling to room temperature at a controlled rate of 80‹ F. per minute. Annular electrodes 15 and annular or disc electrode 14 both of nickel and concentric with zones 12a and 13a are then ohmically connected to body 16 in successive soldering operations using a 60/40 lead tin solder containing 18% cadmium. The device is subsequently etched and encapsulated. In a second embodiment (Fig. 4) the P-type zones 22, 23 and ohmic electrodes 24, 25 are in the form of parallel strips extending over the full width of a rectangular wafer. The devices may be operated as unipolar transistors with the ohmic electrodes serving as source and drain and the P-type zones commonly serving as gate electrode. Alternatively the P-type zones are connected as emitter and collector respectively. In this case a bias is preferably applied between the two ohmic electrodes serving as base electrodes, though it is also suggested to merely connect them in parallel to serve as a common base electrode or to use only one or the other. When the device is connected in the above manner it is found that for a given collector current the gain is greater with the common base electrode arrangement than when using only one of the electrodes and that the result of applying an increasing bias between the two base electrodes is to increase the gain for high collector current values with a corresponding sacrifice of gain at low currents.

Abstract: 1,079,409. Phase sensitive rectifiers. LOSENHAUSENWERK DUSSELDORFER MASCHINENBAU A.G. Oct. 5, 1964, No. 40528/64. Heading H3A. [Also in Division G1] A phase sensitive demodulator for a balancing machine comprises a voltage divider formed by a fixed resistor 12 and a photo-resistor, preferably a pair of oppositely poled photo-diodes 13, 14. An alternating " unbalance " measuring voltage Ue, derived e.g. from a transducer responsive to vibrations of a bearing of the machine, is applied across the divider and the photo-resistors are illuminated by a source 16 periodically obturated at 17 at the frequency of rotation of the body under test (preferably during one half of each rotation of the body). The voltage across the photo-diodes after filtering at 18, 19 thus produces an output direct voltage Ua of magnitude and polarity corresponding to the magnitude x cos # and phase sense of the measuring voltage Ue relative to the phase # of the chopper action at 17.

Title: Graphic Signal-Recording Apparatus Incorporating Electrographic Scale-Recording Means.
Inventor: LLOYD WILLIAM ARTHUR
IPC: G03G15/32
Filed: 1967-09-06
Abstract: 1,178,300. Recording-apparatus. VARIAN ASSOCIATES. Sept.6, 1967 [Sept. 12, 1966], No. 40788/67. Heading G1J. Recording-apparatus with a movable electrographic recording web 2 on which a signal applied to input terminals 12 is recorded by a writing device 11 incorporates an embossed conductive roller 6 for electrographically writing on the web 2 a series of longitudinal amplitude-scale indices and also an electrode 7 writing a series of lateral time-scale marks. The signal writing device 11 is preferably a stylus electrode, but may be an electrode array or an ink-fed pen. The electrode 7 may be made of 0À005" thick beryllium copper sheet, bent and supported to exert a small spring-bias force against the writing surface of the web 2. A pulser 9 serves to pulse the writing potential applied to the electrode 7 from a source 8 to produce time-scale indices. Circumferential ridges of say 0À003" in height may be embossed on a brass cylinder 6 by photoengravingand numerals may be embossed to identify major sub-divisions of the scale. A felt pad 28, e.g. 1/16" thick, between the web 2 and a base plate electrode 3 ensures even contact between the web and roller and suppresses the intensity of the scale lines by causing some dissipation of writing potential. A variable resistor 29 may also subdue the intensity of the scale indices relative to the signal trace. Alternative amplitude scales may be produced by switching between two rollers 6 and 6' or a choice between four scales can be provided by supporting four rollers on the arms of a spider, rotated 90 degrees to change scale. In the case of electrostatic writing, the invisible signal and scale images are developed by a developer 34 which applies finely divided pigment particles, in a dielectric fluid suspension of liquid or air, to the charged images. The developer 34 is not needed when an electro-sensitive web is used, with which current may produce discolouration by electro-lytic action or may burn an opaque coating to reveal a contrasting colour.
