Title: Improvements in or relating to crystal contact devices
IPC: H01L21/00
Filed: 1949-03-18
Abstract: 680,528. Crystal rectifiers. GENERAL ELECTRIC CO., Ltd., JAMES, E. G., and KYTE, D. J. April 24, 1950 [March 18, 1949], No. 7480/49. Class 37. The process of manufacture of a crystal contact device includes the steps of causing a metal whisker to be brought into contact with a crystal element at a predetermined pressure and then submitting the device to vibrations while measuring the input capacitance, until this falls within a predetermined range. Fig. 1 shows the device which is suitable for connection to a coaxial line, and may be used for mixing radio frequencies. The metal whisker 2 is fixed to a metal stud 4 in a ceramic disc 6 which is fixed in a brass housing 3. The silicon crystal 1 is fixed to a resilient cup 11 which is slid into position during assembly to provide the desired pressure between the whisker and the element. The device is then placed on a vibration table, the vibrations having the effect of increasing the capacitance measured between elements 4 and 3, and vibrations are continued until this capacitance falls within a desired range. The cavity containing the operative elements is then sealed by a cup 12 which is coated with a synthetic resin cement. Reference is made to Specifications 635,690 and 657,793, [both in Croup XL (c)].

Abstract: 843,828. Valve waveform shaping circuits. RANK CINTEL Ltd. March 13, 1958 [March 13, 1957], No. 8275/57. Class 40(6). A test signal generating circuit comprises a first valve normally conductive follow ed by a second valve which is nor mally non-con ductive, the saic second valve hav ing as its anode load a resistor shunted by a capa citor. An inpu waveform A is fed into the point 4 and is differen tiated by the capacitor. 3 and the effective input resistance of the valve under grid current conditions,. and the negative going potential produced by the trailing edge cuts valve 1 off and produces at its anode a waveform B which is fed on to the grid of valve 7 causing this valve to become conductive. During the duration of this positive going potential the anode of valve 7 falls approximately linearly and when the valve again becomes non-conductive there is an exponential return due to capacitor 10 and resistor 9 which effectively reaches the datum potential in the interval between successive pulses. The resulting output waveform C is taken from terminal 11. In order to vary the amplitude of the output a variable potentiometer 12 is included in the screen circuit of valve 7.

Title: Cellulose ester and process of forming the same

Filed: 1922-03-23
Abstract: By heating in the undissolved state nitrocelluloses and nitrocellulose products such as smokeless powders, celluloids, or nitrocellulose films or coatings such as imitation leather, the viscosity of the doughs or solutions prepared therefrom is permanently lowered.  The nitrocellulose &c. may be heated in the dry state or in non-solvent liquids, or after gelatinization but without solution, or by a combination of these methods; and the extent to which the viscosity is reduced depends on the temperature and the duration of the heating, the reduction being greater as the temperature is higher.  In examples, smokeless powder is heated in an autoclave with water or other non-solvent liquid to temperatures of 100-140 DEG  C. or higher; nitrocellulose is gelatinized with camphor and alcohol, and the mass heated in an autoclave.  Nitrocellulose or a nitrocellulose product is heated in air, or preferably in an indifferent gas, to 120 DEG  C. or 130 DEG  C.  Specifications 8951/85 and 18233/98, [both in Class 9, Ammunition &c.], 13023/07 and 11941/11 are referred to.

Abstract: 1415396 Smoothing yarns; warp sizing BURLINGTON INDUSTRIES INC 21 Feb 1973 8525/73 Headings D1F and D1M In a process of sizing yarns and laying down randomly projecting peripheral fibres thereof, a sheet or web 18 of yarn e.g. from warp section beams, passes into a box 10 of sizing solution 12, under a free or driven roller 14, thence through driven squeeze rolls 16. The sheet then passes over a single grooved roller or, as shown, it is subdivided into sheets 19 each of which passes generally tangentially over a grooved roller 20 rotatably driven (as by belt or gears) from a motor 23 in a direction opposite or similar to the direction of yarn travel but in any case with a speed differential therebetween. The width of each groove is such that the single yarn passing therethrough is subjected to a compressive force during at least a portion of its passage, and the depth of the groove is greater than a major crosssectional dimension of the yarn: thus a resistive drag is imparted to the projecting fibres which are thereby wrapped helically about the yarn surface. The surfaces of the grooves are cleaned to prevent accummulation of size and fibre therein by streams of dry steam applied from slotted tubes 22 supplied from a steam generator 24 through conduits 26. Treated yarns are dried by spreading and passing over rotary drying cylinders 28. Each roller 20, Fig. 2, may be machined from a cylinder of wear-resistant material e.g. acetal resin plastics or metal, to form grooves 30 or discs 32 (or washers of alternating different diameters) may be assembled on, and keyed at 40 to, the shaft 38 to form the grooved construction.
