Abstract: 649,885. Oscillographs; electromagnetic voltmeters. GRASS, A. M. Oct. 6, 1948, No. 26043. Convention date, Oct. 9, 1947. [Class 37] [Also in Group XV] In order that the size of an oscillograph unit shall be relatively small so that a number of units may be placed side-by-side for recording in separate channels, the moving coil is so arranged that its axis is included in the median plane of the magnets. A frame is formed by iron side walls 10, Fig. 1, forming the pole shoes of the permanent magnets, and top and bottom bearing plates 12, 14. A movable coil is wound on a nylon former 16 within which is a fixed iron core 18, the coil being movable between the parts 10, 18 with as small an airgap as possible. The coil is mounted on shafts 20, 22 journalled in the plates 12, 14 and controlled by springs 26, 28 which also serve as leads to the coil. Wires 36 connect the ends of the springs to a connector plug 38. The coil is of considerably greater axial length than thickness. The magnet assembly comprises two magnets 40 of high coercive material having relatively high and thin faces corresponding to the dimensions of the coil. The magnets are bolted to the shoes 10 and the magnetic circuit is closed through an iron base 42. Several such magnet and coil assemblies are stacked side-by-side as shown in Fig. 2, for use in multiple channel recording. Each recording unit includes a pen having a split clamp 44 which is clamped about the shaft 20 and held by a screw 46. A beryllium copper spring 48 has a vertical leg secured to the side of the clamp 44 and a horizontal leg extending outwardly and carrying a pen housing 50. This is formed from a triangular aluminium plate having its sides 52 bent down. A stainless steel ink-feeding tube 54 passes under the plate 50 and at its rear end 56 passes upwards through a hole in the plate. A smaller tube 58 is sweated into the end of the tube 54 and is bent down so as to engage a chart 60. The tube 54 is large enough to convey ink to the tube 58 without clogging. The inkwell comprises a cup 61 from which leads a stainless steel tube 62 connected to the tube 54 by a flexible plastic tube 64. An inverted cup 66 forms a cap fitting over the cup 61 and is provided with an air vent 68. To prime the pen the vent 68 is closed by the finger and the cap pressed down lightly so that ink is forced to the pen point.

Title: Improvements in machines for indicating the force of a blow
IPC: A61B5/22
Filed: 1922-10-02
Abstract: 206,654. Barnhart, C. L. Oct. 2, 1922. Strength-testing apparatus.-Relates to devices for indicating the force of a blow such as employed at places of amusement, and consists of a construction of a coin-freed machine in which an anvil member, normally held unresponsive to a blow by coin-freed means is adapted to actuate indicating mechanism which remains in the position attained. The machine comprises a casing 1 and an anvil block 10. A tube or rod 83 joined to both serves as a guide for a striker 80. The top surface of the block 10 is cut away at 12 to allow the anvil member 14 to pivot about a point 16. The member 14 is normally held in the position shown in Fig. 3 by a pivoted lever 50 which is released by a coin, while the striker is held in the lower position by a spring catch within the guide 83 which is withdrawn when the lever 14 takes its tilted position after a coin has been inserted. The striker is then moved upwards to the dotted position and brought violently downwards to strike the end of the lever 14. A rider 30 guided along the bar 34 is thrown upwards by the other end of the lever 14 and engages a volute cam 29 on the shaft 19 which is rotated and through gearing 22, 23 rotates a needle 26 over a scale, thus giving a measure of the force of the blow delivered by the striker. Two gongs of different tones are provided and the striking mechanisms for the gongs are operated by flexible cords from the shaft 19 when the latter has turned through certain angles. A pawl engaging a crown wheel 63 prevents return of the shaft 19 and of the indicating mechanism. When another coin is inserted, and the handle 62 moved, the end 76 of the lever 50 engages the part 77 and raises the pawl, allowing the indicating mechanism to return to zero. Coin action, mechanical connection.-When a coin is inserted at 67 it drops into a converging channel formed between the lever 50 and an arm 56 pivoted to the lever at 58 and having attached to it side plates. The converging channel allows of coins of varying size being used. After a coin has been inserted, the handle 62 is moved to the other end of its slot and the coin bridging the space between the arm 56 and the lever 50 these are moved together, the arm releasing the lever 14 and the latter taking up a tilted position and releasing the striker 80. -

Title: Anti-fog materials and method of producing the same
IPC: C03C17/32
Filed: 1953-10-06
Abstract: A polyethyleneoxy alcohol is produced by copolymerizing a monohydric alcohol having 12-31 carbon atoms with ethylene oxide in the presence of sodium so as to incorporate therein at least 3, and not more than 7, ethylene oxide groups per molecule of the alcohol, and stabilized by substantially neutralizing alkalinity due to sodium by oxidation with oxygen.  The copolymerization may be effected by heating the alcohol to between 150 DEG  and 200 DEG  C. in the presence of 0.001 to 1 per cent, preferably 0.05 per cent, of sodium and passing in ethylene oxide until the desired number of ethylene oxide groups have been absorbed.  The product is then stabilized by passing oxygen through it for about seven days, preferably at 60 DEG  C.  The product is then preferably allowed to stand in contact with air at 60 DEG  C. for a similar period.  The oxygen treatment may also be effected at room temperature, a period of 2 months being required, or at 100 DEG  C. for about 12 hours.  In an example, cetyl alcohol is copolymerized with about 5 ethylene oxide groups and stabilized by passing oxygen through for 7 days and exposure to air for 7 days. The product may be combined with a finely divided friction agent, e.g. carbon black, barium sulphate, magnesia, calcium fluoride or rouge, to produce an antifog material suitable for application to windows (see Group X).
