Title: A carriage-feeding device for typewriters
IPC: C10G73/06
Filed: 1933-11-14
Abstract: 410,022. Typewriters. WANDERERWERKE VORM. WINKLHOFER & JAENICKE AKT.-GES., Schonau, near Chemnitz, Germany. Nov. 14, 1933, No. 31727. Convention date, Nov. 19, 1932. [Class 100 (iv).] Type-lever actions ; letter-spacing mechanism.-In actions comprising means for completing by momentum the travel of the type-bars, the letterspacing mechanism is operated during the latter half of the momentum travel, repeat operation of the letter-spacing mechanism due to rebound of the typebars being thereby prevented. The action shown in the Figure comprises a type-bar 1 carried by links 3, 4 and connected to a key-lever by linkage which allows the type-bar to travel by momentum during movement of the type-head 2<a> from position 15 to impression position 16. A letter-spacing universal bail 19 is operated by a lug 18 on the link 3 when the type-head is travelling from position 17 to position 16, the distance between these positions being less than half, preferably a quarter or fifth, of that between the positions 15, 17, so that if the typebar rebounds from rest position, repeat operation of the universal bail and letter-spacing mechanism is prevented. Preferably, the universal bail is secured to a bridge 21 having at each side an arm 22 mounted on parallel links 23, 24 secured to shafts 27, 30. An arm 31 on the shaft 30 is connected to a link 38 having an adjustable nut 39 engaging a rocker 40 which is provided with fast and loose dogs 42, 43 co-operating with an escapement wheel 44. The arm 31 is longer than the distance between the nut 39 and the dog-rocker pivot 41. A spring 36 normally causes an adjustable screw 33 on one of the links 24 to engage a stationary stop 34. The escapement is operated when the type-head is moving to and fro between the positions 17, 16, the type-head being at this time in engagement with the aligning-guide 45.

Title: A process for the manufacture of organopolysiloxane resins
IPC: C08K5/057
Filed: 1948-12-08
Abstract: An organopolysiloxane resin is made by reacting an organosiloxane polymer, initially in liquid state and having an average of 1 to 2 hydrocarbon radicals (attached directly to silicon atoms) per silicon atom, with an aluminium alkoxide at temperatures between room temperature and 300 DEG  C., the amount of alkoxide used being between 0.01 per cent by weight of the polysiloxane and a maximum amount which varies inversely with the temperature in accordance with values of 5 per cent of the alkoxide at 300 DEG  C. and 20 per cent at 150 DEG  C.  The polysiloxanes may be made by hydrolysis of organosilanes having from 1 to 2 monovalent hydrocarbon radicals attached to the silicon atom, e.g. dimethyldiethoxy-, ethyltrichloro-, diethyldichloro-, ethylphenyldichloro-, ethylphenyldibromo-, methyltriethoxy-, phenyltrichloro-, and methylphenyldichloro-silanes or mixtures thereof, and they may contain 10 per cent or less of inorganic silicon halides, e.g. SiCl4 and SiBr4.  Aluminium alkoxides specified are the ethoxide, propoxide, isopropoxide and butoxide.  The solid alkoxide may be dispersed in the liquid polysiloxane or may be used as a solution in an organic solvent, e.g. a liquid hydrocarbon which is miscible with the polysiloxane. The preferred temperature range is from 100 DEG  to 300 DEG  C., and the resinification is advantageously effected under anhydrous conditions.  In examples (3) liquid phenylethylpolysiloxane, aluminium butoxide and asbestos are mixed and heated to 115 DEG  C. and the resulting solid, non-tacky material is moulded under pressure at 250 DEG  C.

Filed: 1948-12-14
Abstract: 658,843. Centrifugal pumps and compressors. BELLISS & MORCOM, Ltd. Dec. 14, 1948, No. 32274. [Class 110(i.)] The exit end of each of the passages between the blades of the impeller is made of nozzle-like form which is determined by a pair of mutually inclined side surfaces, the radial extent of which is determined by the intersection with the front surface of an impeller blade of a line drawn at rightangles thereto from the tip of an adjacent blade. In one construction, Figs. 2 and 3, the inner surface of the side walls g of the impeller are substantially parallel over a region h, and are mutually inclined over a zone i to form the discharge nozzles. Preferably, the blades comprise long blades j alternating with short blades k. The inner boundary o of the zone i is determined by dropping a perpendicular n from the tip of a blade k to an adjacent blade j. Modifications are described in which one side wall g is omitted and blades are formed on one or both sides of the remaining side wall, the adjacent casing wall or walls being shaped to form one or both of the inclined walls of the nozzles. In an alternative construction, the short blades k are omitted and, whilst the outer faces of the side walls g are symmetrical, the portions of the side walls between the blades j are progressively thickened from the front face t of any one blade to the rear face u of the next blade, as shown in the developed view shown in Fig. 8. The side edges of the front face t correspond to the lines 2, 3, Fig. 7, and the side edges of the rear faces u correspond to the line 4. Fig. 9 shows a construction in which the impeller side walls g are parallel or slightly inclined over the region ahead of the nozzle zone, but in the zone are formed with inwardly inclined depressions s.

Continuously rotating type carrier on continuously moving carriage.-A continuously rotating type disc 5 having type 1 on leaf-springs 4 is mounted on a continuously traversing carriage 44, the disc rotation and the lateral carriage motions being in synchronism. Type disc construction; arrangement of characters.-The disc 5 carries a number of sliding guide blocks 2 each having a character 1 which projects through an aperture 3 in a flat beryllium copper spring 4 held against the disc 5. The characters are progressively spaced around the disc, Fig. 2 (not shown), to allow for the difference in lateral movement of the disc between different characters. A gap in the spacing permits time for recocking of the hammer. Hammer mechanism.-A hammer head 10 is pivotally mounted in a hammer body 11 on a pin 12 on the type-disc carriage. It is moved by a cam 7 on the type-disc 5 and a follow 15 into cocked position where it is held by a latch of an electromagnet. This is operated at a selected moment to release the hammer which is moved towards printing position by a spring 16 and input is completed by momentum. The hammer mechanism or the guide blocks 2 may be laterally shifted by an angular movement caused by an outer cam mechanism 8, 20 on the disc 5 to allow for the progressive spacing of the characters on the disc. Carriage movement; letter spacing; disc drive.-An electric motor 62 drives a single splined shaft 61 and a gear 58. Gear 58 drives gear 59 and a bevel gear 60 which meshes with a bevel gear 41 on the type-disc 5. A gear 57 is also driven from the shaft 61 and this rotates an internally threaded cylinder 56. The threaded cylinder 56 effects carriage movement when the two parts of a divided and threaded rod 66 spread to engage the internal threaded teeth. This is determined by a pair of swivel links (67) operated by an electromagnet (69), Fig. 5 (not shown). Carriage-return; braking.-Carriage-return is effected by a spring when the threaded rods 66 are moved together: pulleys of a wire are equipped with a brake to slow down the speed of the carriage before reaching the extreme left position.

Abstract: 481,993. Testing coins. BRECKNELL, MUNRO, & ROGERS (1928), Ltd., and DOLMAN, H. J. Nov. 27, 1936, No. 32477. [Class 27] [Also in Group II] The coins pass over two pivoted counterweighted carriers 7 and 8 in succession, carrier 8 being more heavily counterweighted and having adjacent thereto an electromagnet 15 energized by alternating or pulsating current. Overweight coins tilt the carrier 7 and are released. Other coins pass to the carrier 8 and between the poles of magnet 15 which induces eddy currents in them. In the case of coins correct in weight and material, the downward force, due to the combined action of their weight and the repulsion of the magnet 15, tilts the carrier 8 and they are discharged beneath a plate 16 into an " accept " shoot. Underweight coins and discs of spurious metal do not tilt the carrier 8, and pass over the plate 16 to be rejected. A stop may be provided to check the coins on the carrier 8. This stop is displaced, to release defective coins which do not depress the carrier 8, by operation of a press-button, or the drawer or other delivery device of the associated coin-freed apparatus.

Abstract: 1339358 Optical rangefinder RAYTHEON CO 12 July 1971 [31 Aug 1970] 32637/71 Heading H4D [Also in Division G2]  In an airborne water depth finder Fig. 1, a linearly polarized laser beam is vertically directed on to the water surface producing a very strong linearly polarized reflection from the water surface and much weaker scatteredunpolarized-reflections from beneath the water surface and from the water bottom. To reduce the range (90db) of the reflection strengths falling on the photomultiplier detector 24, an optical wedge, Fig. 2, is used at the focal plane of lens 21, comprising a photographic film between two glass sheets and having an attenuation increasing towards its centre together with a cross-polarized filter 32 at the centre. Alternatively all the edge may be linearly polarized. The reflection from the water surface is received only at the centre of the wedge and so is doubly attenuated, whereas the scattered reflections from beneath the surface are received over all the wedge and are less attenuated the further their depth.
