Patent GB-1003758-A (GB)
Title: Microwave switch device
Inventor: ROBINSON STEPHEN JOSEPH
IPC: H01P1/22
Filed: 1962-07-23
Abstract: 1,003,758. Electric analogue calculating. MULLARD Ltd. July 23, 1962, No. 28243/62. Heading G4G. [Also in Division H1] A microwave attenuating device which produces an output dependent upon the level of the input signal comprises a silicon point-contact diode arranged in an arm of a three- or four-arm junction, e.g. a hybrid junction or a circulator. As shown in Fig. 2, two diodes R are arranged in two of the arms of a 3 db. directional coupler. At low input power levels the diodes effectively short-circuit the arms and power from input A is reflected to the output D. At higher values, the diodes have an impedance equal to that of the arms and the input power is absorbed. Where a hybrid ring or hybrid-T is used, it is necessary to insert a quarter-wave section between one of the diodes and the junction. The circuit of Fig. 5 uses a 3-arm circulator, the impedance of diode R determining the amount of power coupled from input arm A to output arm C. If a 4-arm circulator is used, the remaining arm is terminated in its characteristic impedance.

Title: Improvements in or relating to spongy or absorbent bodies and articles and the manufacture thereof
IPC: B32B27/00
Filed: 1921-10-25
Abstract: 192,143. Vianello, O. Oct. 25, 1921. Sponges; sponge substitutes.-Pieces of sponge or spongy material such as skins are cemented together by means of an adhesive, such as indiarubber or celluloid composition, which is insoluble in water. The pieces may be agglomerated so as to form bodies of irregular shape, or they may be placed side by side to form a layer of uniform thickness. Two or more such layers may be superimposed and cemented together. According to another modification, the spongy pieces may be cemented together through the meshes of a fabric or network, the lateral faces of the pieces being either cemented together or not. This spongy fabric may be rolled into spiral form, or layers may be superimposed to form blocks, or it may be used for making gloves, or envelopes which may be. filled with loose pieces of sponges. Before being joined together, the spongy pieces may be made rigid by treatment with a solution of isinglass or gum arabic, which is afterwards washed out. The adhesive may be used either as solution or in the form of powder or thin strips or plates inserted between the pieces of sponge, and subsequently rendered viscous by treatment with a solvent or the vapour thereof. It may afterwards be rendered insoluble bv treatment with an appropriate hardening or vulcanizing agent.

Fats and oils, extracting.-Fatty material is recovered from an emulsion during the circulation of the emulsion against the flow of a volatile solvent through a series of mixers and separators; the fat is dissolved and can be recovered by distillation, and the separators are so constructed that solid material removed with the water does not clog them. The plant shown in Fig. 1 consists of mixers 1<a>, 1<b>, 1<c>, and separators 2a, 2<b> 2<c>. Emulsion is supplied from the container 4 to the mixer 1<a> and it follows the path indicated by the ducts and arrows shown in full lines. The solvent is supplied from the container 6 and follows the path shown by the dotted lines.. The emulsion first meets the solvent in the mixer 1<a> and both pass into the separator 2<a>. The dissolved fat passes through the duct 12 to the distilling apparatus 13 where the fat is recovered. The remainder of the emulsion passes from the separator 2<a> to the mixer 1<b> where it meets fresh solvent, and the mixture passes to the separator 2<b>. The mixing and separating actions continue until the residue from the emulsion passes into the container 15 which may be heated for recovery of any solvent. The separators used are preferably of the type shown in Fig. 2. A rotary cylindrical bowl 21 has a conical top 22 inside which is another conical wall 23. The centrally placed distributor has a conical part 26 which forms the inner wall of the separating chamber for the fat. Each end of the distributor has walls which are practically parallel with the wall 23. The mixture enters through the opening 27 and passes between vanes inside the distributor to its mouth. Any sand or grit is separated by this passage and remains against the wall of the bowl.

Abstract: 334,720. Gleichmann, W. Sept. 20, 1929. Fused quartz. - A method of preparing fused silica free from bubbles consists in feeding pieces of rock crystal, which have been preheated to about 600‹ C., into the flame of an oxyhydrogen blowpipe, so that they are projected by the flame against a surface where they gather to form a fused mass. The nozzle 2 of the blowpipe is fitted into an opening in the wall of a muffler furnace 1, and a funnel 3 is fitted into an opening above the nozzle 2. Pieces of rock crystal 7. stored in a hopper 8, are allowed to fall into an enlargement 5 formed on the higher end of an inclined tube 4. This tube is journaled in bearings 9, 10 and can be rotated by suitable means. The pieces of quartz move along the tube 4, and during their journey they are heated by the flame from a blowpipe 12 which is directed along the interior of the tube in opposite direction to that in which the pieces of quartz are moving. The hot quartz falls through the funnel 3 and is projected by the blowpipe jet 13 against the opposite wall of the furnace where a plastic mass 14 of fused quartz is built up. This is removed from time to time by gathering it on a tool.

Abstract: 1393165 Electro-physical measurements USS ENGINEERS & CONSULTANTS Inc 19 June 1972 [21 June 1971] 28628/72 Heading G1N The resonant frequency of magnetostrictive material such as carbon steel sheet is measured so as to determine Young's Modulus and hence drawability of the material. Initially a standard specimen 5 of material is inserted in driver 4, bias 6 and pick-up 8 coils so as to be supported by the bias coil former. The mechanical oscillations of the magnetostrictive material induce oscillations in the pick-up coil 8 which are fed via a filter circuit 14 which attenuates the second harmonic to amplifier stages 34, 80, the latter feeding oscillations via power limiting lamp 88 to the driving coil 4 to maintain oscillation. Calibrating capacitor 62 is adjusted so that the required frequency is indicated on counter 90. The standard specimen is then replaced by the sample to be measured and if lamp 88 lights at full brilliance the specimen 5 is oscillating at the fundamental longitudinal, resonant frequency of the standard. However if the lamp is dim or off it is not and after checking by tapping the specimen or reversing the bias field remains dim or off it is rejected. The lamp 88 acts as a power limiter in so far as it promotes oscillation when the apparatus is initially energized and its resistance is low and limits the power applied to the driver coil when its resistance increases on becoming incandescent.
