Title: Semiconductor vidicon target having electronically alterable light response characteristics
IPC: H01L27/00
Filed: 1969-05-22
Abstract: 1,211,513. Semi-conductor targets. RCA CORPORATION. 22 May, 1969 [26 June, 1968], No. 26120/69. Headings H1D and H1K. [Also in Division H4] A target for an image conversion device having variable spectral response comprises an N-type semi-conductor wafer 4 with P-type regions 5 at a first major surface forming an array of diodes, and a transparent spectral response control electrode 13 on a transparent insulating layer 14 on a second major surface. The control electrode is of chromium, thermally deposited on the insulating layer 14 of silicon dioxide, and the semi-conductor material is silicon. In use the diodes are reverse biased by supply 9, and light falling on the second major surface generates minority carriers in the wafer which diffuse across to the diodes and change their state of charge, these changes being detected by an electron beam 2 scanning the diodes to produce an electrical output signal. The penetration of light into the wafer to generate minority carriers is proportional to the wavelength of the light, so that the device is more responsive to light of longer wavelengths. To reduce the response to light of shorter wavelengths the control electrode 13 is negatively biased to produce a depletion layer 17 in the wafer at the second surface, this surface having been treated to introduce surface defects which serve as recombination centres for the minority carriers generated in this layer by the light of shorter wavelengths so that they do not penetrate the wafer further than the boundary 18 of layer 17 and have no effect on the diode array. To prevent inversion at the surface under the control electrode due to high negative bias voltages, a P-type region 21 is formed in the wafer adjacent to and connected to the control electrode via a rectifying diode 22 to serve as a sink for the minority carriers. To increase the response to light of shorter wavelengths, the control electrode is positively biased to produce a field which is orientated to impel the minority carriers towards the diode array. In this case the diode 22 prevents positive biasing of the P-type region 21. In a further embodiment a Schottby barrier structure is employed instead of P-type region 21, and is connected directly to the control electrode. When this arrangement is used the control electrode may not be positively biased.

Abstract: <PICT:0353747/IV/1> <PICT:0353747/IV/2> <PICT:0353747/IV/3> Artificial silk, particularly viscose silk, spu on bobbins is washed and, if desired, desulphurized, bleached, acidified, soaped, oiled, and otherwise after-treated with liquids, and the bobbin laps are then removed from the bobbins and dried in a condition which allows unrestrained shrinkage.  The bobbin lap may be produced upon a conical bobbin which can afterwards be withdrawn from the thread coils, or bobbins having adjustable diameters may be employed.  The bobbins may comprise a plurality of parts which may be caused to collapse or slide together so as to effect a diminution of the periphery.  They may be constructed of sheet material cut along a generating line so that they may be compressed spirally for enabling the bobbin lap to be removed. Removal of the thread coils from conical bobbins may be assisted by the application of a lubricant such as soap.  After the bobbin lap has been dried it may be brought with or without twisting into the form of a bobbin, cheese, bottle-bobbin, canette, cop, hank, or other desired form.  It may be unwound from the outside or inside as desired.  As shown in Fig. 1, the lap a is mounted upon a holding core i upon which a spinning plate m is then secured. The core i rests on the spindle l and is driven by means of a belt k.  The thread is unwound from the revolving lap a and supplied with twisting to a conical bobbin n.  In Fig. 2, the lap a is placed in a sleeve o mounted on the spindle l, and the thread is drawn off the edge of a cover p which serves as a spinning plate.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the feature of removing the bobbin laps from the bobbins and then subjecting them to the wet treatments.  As shown in Fig. 1 (Cancelled), the laps a wrapped in permeable material b are mounted upon a perforated tube c inserted in the bottom g of a treatment trough.  The individual laps are separated by rubber rings d, and the whole series is held in position by a cover e secured by a key f.  The treatment liquids are passed through the thread layers either outwardly or inwardly by means of suction or pressure.  This subject-matter does not appear in the Specification as accepted.

Title: Apparatus for making gas-charged or aerated beverages
IPC: B67D1/00
Filed: 1965-06-22
Abstract: 1,101,499. Proportioning, mixing and aerating liquids. G. TREMOLADA. 22 June, 1965 [26 June, 1964; 20 Feb., 1965], No. 26446/65. Heading B1C. [Also in Division Fl] In apparatus for preparing aerated beverages the ingredients are metered by a proportioning reciprocating pump having cylinders 1, 2, 3 for gas, syrup and water respectively; the pump is double acting and operated by the pressure of carbon dioxide in cylinder 1. The carbon dioxide supply first passes through a piston valve 5 actuated by limit stops on the common piston rod 4 to change over the gas supply to a piston 9, which actuates a piston valve assembly 10 which changes over the supply of gas, syrup and water to the cylinders 1, 2, 3. The gas is pumped to an accumulator 51 and syrup and water to a tank 52 where they are mixed; the ingredients then pass through pipes 54, 55 to a device 53 (see also Fig. 4, not shown) where the beverage is charged with gas by passage through a succession of venturiform constrictions and delivered to a storage tank 60 from which it may be drawn off through line 65. An intercepting valve 106 will stop draw-off if the float 107 in the syrup tank 104 falls, which may be caused by shortage of syrup or by failure of gas pressure causing the stem 114 of a spring-loaded piston 112 to depress the float.

IPC: H03H9/56
Filed: 1968-06-04
Abstract: 1,197,129. Piezo electric elements. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 4 June, 1969 [4 June, 1968], No.26453/68. Heading H1E. [Also in Division H3] A monolithic crystal filter comprises a quartz slab 1 having a series of resonators formed by electrodes coated on its opposite faces. Thus, one face of the slab has electrodes 10 . . . 13 and the opposite face has corresponding electrodes such as the electrode 21, the electrodes 11, 21 comprising one of the four resonators. To reduce unwanted shear vibrations of the slab 1 which give rise to unwanted resonances in the filter stop band, the slab 1, Figs. 1, 2, is supported over a cavity 26 in a member 25 by means of a layer 28 of adhesive extending around the entire periphery of the slab, the material of the layer 28 being ultrasonically more lossy than the material of the slab. The layer 28 may be a polystyrene-xylol cement or an expoxy resin and the support 25 may be of thermo-setting resin or bonded glass fibre board. The opposite face of the support 25 is coated with silver paste or copper sheet 34, the coating being connected to earth to reduce inter-electrode capacitance. The electrodes are connected to terminal pins such as 31, 33, which extend right through the support 25, by means of strips such as 15, 16, 32. The filter operation may be further improved by coating the periphery of the opposite face of the slab 1 with a band 35 of a material which is ultrasonically more lossy than that of the slab. In a modification, Fig. 5, the support 25 is formed by sticking four insulating strips 39 . . . 42 to an insulating base 38. In another modification (Fig. 6, not shown) the support 25, instead of having a cavity, is provided with an aperture. According to a further modification, Fig. 7, the slab 1 is mounted between two apertured supports 25<SP>1</SP>, 25<SP>11</SP> by means of adhesive layers 28<SP>1</SP>, 28<SP>11</SP>. In a final modification, Fig. 8, the slab 1 is mounted in a support 50 by strips 51 of neoprene or polythene secured by adhesive layers 52, 53.

Abstract: 1,008,082. Stacking ice-cream sticks. UNILEVER Ltd. Oct. 5, 1962 [July 21, 1961], No. 26625/61. Headings B8A and B8C. Ice-cream sticks are discharged from hopper 4 by endless conveyer 5 and 6, surplus sticks being rejected back by the counter rotation of wheel 9 so that the sticks in roughly parallel formation are discharged down shoot 12 on to the surface 13 vibrator conveyer 2. The sticks lie down surface 13 and pass between rollers 19 and 18. Roller 19 is a regular cylinder whilst roller 18 has grooves cut in it corresponding to the triangular grooves formed in surface 13. The rotation of wheel 19 causes the scattering of surplus sticks so as to distribute them along the roller. The rotation of wheel 18 feeds a stick through each groove one at a time on to surface 13 which feeds them past wall 20. Wall 20 is shaped to correspond with the troughs formed in surface 13 and has a V-shaped slot cut into it for each trough, so that the stream of sticks proceding down each trough pass through the corresponding V-slot which is so shaped as to permit only the passage of one at a time. The streams of side-by-side sticks now pass between rollers 25 and 26 which are rotated to shoot the sticks into corresponding receivers 23. Each stick is shot into the bottom of the receiver and is guided by slope 27 so that the stacks of sticks is formed from the bottom and displaced upwards by the arrival of the next stick. In this way a plurality of stacks of sticks is formed side by side.

Abstract: 1,117,321. Calculating check digits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 25 June, 1965 [30 June, 1964], No. 27039/65. Heading G4A. A circuit arrangement for calculating check digits comprises a pulse source supplying in succession groups of pulses aÁ corresponding to the digits of a number (or equivalent characters) alternating with groups of M pulses, the pulses being fed directly to a modulo M counter Z and also via a delay element V in a parallel circuit controlled by a switch S which is closed when the counter passes through zero. In one example a check digit for the number 35231 is derived, using a modulo 11 counter, as follows:- In another example doubling of the counter reading takes place after the entry of the character pulses. A check digit for the number 571906 is derived, using a modulo 13 counter, as follows:- Alternatively, instead of employing a delay element, groups of 2M (or, more generally, kM) pulses could be supplied by the pulse source, the switch controlling only the extra pulses. In another modification, a plurality of delay elements, arranged in parallel, could be used to triple or further multiply the counter residues. In addition to the check digit derived as above, a simple parity check digit may be provided.
