Title: Tape scanning device for telegraph or such like systems

Filed: 1958-12-30
Abstract: 851,467. Type printing telegraphy. DE STAAT DER NEDERLANDEN TEN DEZE VERTEGENWOORDIGD DOOR DE DIRECTEUR-GENERAAL DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Dec. 30, 1958, No. 42015/58. Class 40(3). In a tape scanning device of the type in which the tape is advanced by a periodically rotating wheel and in which one or more contacts signal whether or not the tape has moved correctly, there is provided behind the scanning head a device which engages with the transport perforations and which, due to the tape movement, actuates the contacts. If desired the device may cut the transport perforations longitudinally. On rotation of the eccentric disc 11, via a one-revolution device, lever 14 raises lever 17, 18 and the point 19 engages in a transport perforation. Next, lever 6, 7 is raised by the disc 11 causing the pawl 4 to advance the transport wheel 3. As the tape moves so lever 17, 18 is moved to the left. In turn, lever 21 moves about pivot 22 under the action of part 18 and signal contact 26 is opened. On further rotation of disc 11 lever 17, 18 is withdrawn from the tape and returns to the position shown, contact 27 being re-opened. In the event of incorrect tape movement due to a break in the tape, lever 17, 18 will not be moved forward and therefore contact 26 not opened so that, by means of known circuitry, the one-revolution device is not allowed to operate. By adjustment of the relative positions of the two parts 17, 18 of lever 17, 18 a knife 20 may be made to cut through the tape between two transport perforations when the lever is raised.

Title: Multi-layer semiconductor photovoltaic device
IPC: H01L31/06
Filed: 1975-10-17
Abstract: 1514548 Photovoltaic devices SONY CORP 17 Oct 1975 [19 Oct 1974] 42806/75 Heading H1K A photovoltaic semiconductor device comprises a series of 2N zones (where N is an integer > 1) alternately of P and N type, all zones, apart from the two outermost from which the output is derived, having a thickness less than the minority carrier diffusion length therein whereby transistor action can take place across them. For optimum output the construction should be such that the transistors of which the two outermost zones are the emitters have normal current amplification factors a above 0À65 and preferably substantially 1, and the inverse as of these transistors and the normal and inverse as of transistors formed by groups of inner zones are between 0À2 and 0À7, preferably 0À5. In one device, Fig. 4, based on an N type Si substrate 3 the inner P zone 4 is formed by epitaxy or diffusion and the outer zones 2, 5 by diffusion, and the light receiving face, which has a reflection reducing coating 9, e.g. of polysilicon containing oxygen and optionally nitrogen, carries a comb-shaped electrode 6. A first alternative structure with its junctions nearer the light receiving face to improve its short wavelength response is formed on a relatively thick N substrate forming one end zone. The emitter efficiency of each end zone is improved by highly doping its surface to provide an LH junction within a diffusion length of the emitter junction. In a modification of this for use in the inverted position to provide an enhanced long wavelength response the high surface doping of the N zone is confined to the area beneath the electrode to reduce unwanted absorption. Details of doping levels, dimensions and processing steps are given.

Title: Process for preparing crystalline polymers, the polymers so prepared and articles made therefrom
IPC: C08F255/00
Filed: 1962-11-13
Abstract: Solid crystalline ethylene/propylene copolymers having a density of at least 0.87 and an inherent viscosity in tetralin at 145 DEG  C. not greater than 2.4 are prepared by initially polymerizing one of the olefine monomers to obtain a preformed polymer, then polymerizing the other olefine in the absence of the olefine first polymerized but in the presence of the said preformed polymer until a polymer containing 93 to 99.9% by weight of polymerized propylene is obtained.  The polymerization is carried out using a solid stereospecific catalyst and the propylene polymerization is carried out in the presence of hydrogen and at a temperature from 0 DEG  to 120 DEG  C. and a pressure from 0 to 1000 p.s.i.g. Preferably the olefine first polymerized is propylene and the amount of hydrogen used is not more than 2% by weight of the propylene monomer.  The multi-stage polymerization can be carried out in a single reactor having separate reaction zones, or in separate reactors or in an elongated tubular reactor.  A batchwise method may also be used. The low temperature stereospecific catalysts are initially mixtures of at least two components, component (1) being a transition metal halide and component (2) being a Group Ia or II metal or aluminium, or analloy of metals of Group Ia and/or II and/or aluminium, or a halide, hydride or organometallic compound of the above metals, or a complex hydride or complex organometallic compound of boron or aluminium and a metal of Group Ia or II.  Lists of suitable catalyst components are given.  In addition a third catalyst component may be added, e.g. alkali metal halides, magnesium oxide, aromatic ethers, for example diphenyl ether, hydrides or sodium, potassium and lithium, alcoholates or oxides of sodium, potassium, lithium, calcium, magnesium barium, strontium, aluminium, titanium and zirconium. Tertiary amines and tertiary phosphoramides may be used as third components with alkyl aluminium halides.  In the examples ethylene/propylene copolymers are prepared using mineral spirits as reaction medium and an aluminium triethyl/titanium trichloride catalyst. The polymers may be used in moulding film and fibre applications.  Antioxidants, stabilizers, slip agents, pigments, extenders, other resins, plasticizers and fillers may be added to the polymers.  The polymers may be thermally degraded to low molecular weight liquid and waxy polymers.

Abstract: 1481084 Indicators of imbalance of brake circuits AUTOMOTIVE PRODUCTS Ltd 22 Sept 1975 [7 Oct 1974] 43324/74 Heading F2F A pressure differential indicator 21 indicates a pressure difference between the circuit pressures of a dual hydraulic braking system correponding to failure of either circuit while allowing relatively small movements, to avoid seizure of the operating piston of the indicator, without indication. The indicator comprises a stepped bore 36 housing a stepped piston having a large diameter part 37 and a smaller diameter part 38 acted on by pressure in rear and front brake circuits respectively generated by tandem master cylinder 11. In normal brake operation the piston is centred in a neutral position by pin 52 and springs 48 and 53 but may perform small movements about the central position in response to small fluctuations in pressure, limited by the contact of washers 55 and 54 with abutment 56 and the end of pin 52 remote from the piston respectively. If either brake circuit should fail, the resulting relatively-large pressure difference across the piston will create a sufficient force thereon to slide pin 52 through either of the washers 54 and 55 with the result that either of piston parts 37 or 38 will contact probe 46 to operate a warning light. The line from the indicator to the rear brakes 29, 31 incorporates a pressure reducing valve 28 which is bypassed via line 32 in the event of failure of the front brake circuit.
