Abstract: 362,054. Retractive switches ; snapaction switches. BOSCH AKT.-GES., R., 4, Militarstrasse, Stuttgart, Germany. Sept. 23, 1930, No. 28357. Convention date, Oct. 4, 1929. [Class 38 (v).] A switch ring for the steering wheels of vehicles comprises upper and'lower portions 1, 2, depression of the portion 1 sounding the horn, rotation of the portion 1 to right or left operating direction indicators, and raising of the portion 2 operating a screening device. The portions 1, 2 overlap each other as shown in Fig. 4 and are secured by bolts 6, arranged so as to allow the necessary armount of movement, to a ring 3 fixed by bolts 4 to the steering wheel. Springs 5 press the portions 1, 2 away from the ring 3. Downward and upward pressure on the portions 1, 2 causes contact springs 10, 14 respectively to be moved into engagement with contacts 13, 17 in the horn and screening circuits. Rotation of the portion 1 to right or left causes a U-shaped contact spring, Fig. 3 (not shown), to be pressed into engagement with a contact of the right or left direction indicators and the portion 1 is held in this position by studs engaging depressions in a leaf spring. Two centring springs then return the portion 1 to its original position when the movement is started by hand.

Patent GB-1057048-A (GB)
Title: Method of forming superconducting metallic films
IPC: H01L39/00
Filed: 1963-07-19
Abstract: A superconducting metallic film of niobium, tantalum or vanadium is formed by vapour depositing the metal at a rate of at least 0.5 microns/ hour on to a substrate (e.g. of copper, aluminium, <PICT:1057048/C6-C7/1> <PICT:1057048/C6-C7/2> quartz, mica or glass) heated to a temperature in excess of 25 DEG C. in a chamber evacuated to a pressure of 1 x 10-5 to 5 x 10-5 mms. of mercury. The initial evaporation getters oxygen and oxygen - containing compounds in the chamber and the metal subsequently deposited forms the superconducting layer.  A molybdenum shield may be positioned between the vapour source and substrate during gettering to prevent deposition of oxygen contaminated metal on the substrate.  A non-metallic substrate may be heated to above 600 DEG C. during deposition to improve adhesion of the deposited layer.  In making superconductive alloys, e.g. of niobium-tin, alternate layers of the metals are deposited and then the temperature of the substrate is raised to alloy the layers by diffusion.  Figs. 1 and 5 show apparatus in which the metal to be deposited is heated respectively by electron bombardment and induction.  Fig. 1 shows a metal source in the form of a rod 62 with a terminal bead 63, and a substrate 24 on a heating member 22.  A heated tungsten wire 41 provides electrons to bombard the bead 63 which is maintained at a positive potential. A molybdenum screen 49 maintained at a negative potential serves to focus the electrons on the bead.  Molybdenum shield 83 can be pivoted to shield the substrate from the metal vapour during gettering.  A second metal source 73, e.g. of tin, is contained in an heated by a molybdenum wire 72.  The substrate may be a wafer or a cylinder, the cylinder being rotated during deposition to ensure the production of a uniform layer over its curved surface.  Fig. 5 shows a metal source in the form of a rod 115 with terminal bead 116 heated inductively by a coil 117. A condenser 109 with water inlet 110 and outlet 111 surrounds the top part of the evacuated bell jar 105. Glass rod 119 shadows a portion of the condenser wall to prevent formation of a continuous annular metal deposit thereon, so as to allow effective heating of the metal source.

The guide members C, C<2> are arranged so that the table A and the foodstuff clamped thereon may project through the guide members to the extent permitted by the stop D which comes into contact with the cut surface of the foodstuff. A suitable clamping- device A<5> is attached to the table A which carries the vertical side portion A<2> so that the foodstuff is held between the clamp A<5> and the side portion A<2>, spikes A<4> being provided to prevent movement. The table A and vertical portion A<2> are covered with sheet metal A<3> and are guided by sidepieces B<2> of the framework B. The foodstuff is prevented from entering the space between the side portion A<2> and the rail B<4> by bars B<3> projecting from the rail B<4> and entering holes in the side portion A<2>. The table A may be provided with a step-by-step feed-device. In a modification of the knife-guiding members, the transverse distance between the limbs of the members can be varied to accommodate articles of various widths.

Title: Dinitrobenzoxazoles
IPC: C07D263/56
Filed: 1955-10-12
Abstract: The invention comprises dinitrobenzoxazoles of the formula: <FORM:0771431/IV(b)/1> wherein R is either ethyl or n-propyl.  The novel compounds may be prepared by reacting picramic acid with propionic anhydride or nbutyric anhydride in the presence of a dehydration catalyst, e.g. phosphoric acid, sulphuric acid, benzene sulphonic acid, toluene sulphonic acid or a cation exchange resin in the acid form.  At least 2, preferably 3 to 6, mols. of anhydride are employed per mol. of picramic acid.  Solvents such as xylene, toluene, or the acid from which the anhydride is derived, may be used.  Temperatures of 75-170 DEG  C., and reaction times of 1/2 to 6 hours or longer, are suitable.  The reaction may be carried out at the boiling point of the reaction mixture, either under reflux or with distillation of solvent or by-products.  The product is separated by filtration or extraction with solvents.  In examples, picramic acid is reacted with propionic anhydride in the presence of sulphuric acid, benzenesulphonic acid, or sulphonated styrenedivinylbenzene copolymer in the acid form, to give 2-ethyl-5,7-dinitrobenxoxazole; picramic acid is reacted with n-butyric anhydride in the presence of sulphuric acid to give 2-n-propyl-5,7-dinitrobenzoxazole.  The products are useful as intermediates and as active constituents in bactericides and fungicides and parasiticides.ALSO:Dinitrobenzoxazoles of the formula <FORM:0771431/VI/1> where R is ethyl or n-propyl, are the active toxic constituents of bactericidal and fungicidal compositions and veterinary preparations for the control of gastrointestinal parasites in domestic animals.

Title: Precision measuring instruments
IPC: G01B11/00
Filed: 1972-06-21
Abstract: 1400293 Electro-optical measuring apparatus OPTOGRAMS Inc 21 June 1972 [28 Feb 1972] 29147/72 Heading G1A Measuring apparatus comprises a fixed and a movable jaw biased together by a constant tension spring and an encoder carrying equally spaced lines and connected to the movable jaw so that it interrupts a light beam when the movable jaw is moved and produces pulses, in number proportional to the displacement. The device may be in the form of a micrometer as shown or may be a height gauge or a probe type depth micrometer. The encoder may be linear or rotary, transparent or opaque and the lines may interrupt a through beam or reflect the light beam. The method of operation is said to be to move the jaws apart, place the object between them and then allow them to return to contact the object. A counter records the number of pulses in each movement and is said to be able to detect the direction of movement and hence to give a reading proportional to the size of the object. As shown, Fig.2, the moving jaw 38 slides on rods 46, 47 and is biased towards fixed jaw 36 by constant tension spring 55. The encoder 72 is attached to the upper part of movable jaw 38 and moves linearly to interrupt a light beam from the source mounted in block 64. In a second embodiment, Fig.14, a nut 230 mounted on movable jaw 38 rotates a lead screw 222 and drives a rotary disc 135 with radial lines past a light source and receiver 68. In a third embodiment, Fig.9, the encoders are driven by a tape passing round precision rollers. The ends of tape 147 are both clamped at 145, 146 in the upper parts of the movable jaw 38 and the tape passes round precision rollers 150, 152 and guide rollers 148, 149, 154. Both precision rollers 150, 152 carry encoders 135a, 135b respectively and the light beam 66 passes through the overlapping part of the encoders. Many variations of this tape and roller system are described. For example, a single encoder, mounted on precision roller 154 may be used or the tape may stretch from movable jaw 38, round the encoding roller and then to another mounting kept taut by a constant tension spring.
