Title: Means for plotting isograms
Inventor: EGGLETON MAURICE ARTHUR
IPC: G01K3/14
Filed: 1967-07-07
Abstract: 1,217,854. Recording-apparatus. JOSEPH LUCAS (INDUSTRIES) Ltd. June 13, 1968 [July 7, 1967], No.31444/67. Heading G1J. Apparatus for plotting isograms comprises a market 14 moved over a surface 15 in correspondence with the movement of a voltage probe 13 over the surface 11, for which voltage isograms are to be plotted, the marker 14 being operated by a solenoid 18 to make a mark on the surface 15 whenever a detector 16 coupled to the probe 13 senses a desired voltage value selected by adjusting a selector 17 associated with the detector 16. The apparatus can be used to plot isograms for the surface distribution of any variable parameter which can be represented by a surface distribution of electrical potential and, in particular, to plot thermal isograms for any particular cross-section of a die with cooling holes by simulating the crosssection under examination with a sheet of conductive paper, painting thereon the shape of the cross-section of a cooling hole with silver paint and applying voltages at two points proportional to the temperatures measured at those points.

Title: Viral anti-body detection
IPC: G01N33/569
Filed: 1974-07-19
Abstract: The essential component of the diagnostic composition for detecting antibodies against a specific virus in body fluids is a gel which contains intact erythrocytes with the corresponding virus on their surface. It is moreover possible for the virus particles either to adhere directly to the surface of the erythrocytes or else to be connected to the erythrocytes by means of a coupling member. The gel expediently contains a complement in an amount sufficient to ensure lysis of the erythrocytes. In addition, the gel can also contain bactericidal and/or fungicidal agents as well as agents which prolong the life of the erythrocytes. The diagnostic composition can be used in particular for the diagnosis of influenza, parainfluenza, mumps, measles and rubella and of a number of other viral diseases.

Title: Process of refining acrylonitrile by distillation
Filed: 1952-12-19
Abstract: Acrylonitrile which contains small quantities of divinyl acetylene (e.g. 0.3 to 1 per cent) and water (e.g. 3 per cent) is purified by submitting the crude acrylonitrile to distillation in a fractionating column and maintaining in the top section of the column a water-content which is 20 to 300 per cent of that of the divinyl acetylene while maintaining a head-temperature of 65-70 DEG  C., whereby a ternary azeotrope comprising acrylonitrile, divinyl acetylene and water leaves the top of the column, and substantially anhydrous acrylonitrile, free from divinyl acetylene, is obtained as bottom product.  If the crude acrylonitrile is saturated with water, the adjustment of the water content in the column is advantageously effected by withdrawing a water-rich side-stream from the column.  In cases where the crude acrylonitrile contains less than 2 per cent water, additional water is added thereto prior to the distillation. The crude acrylonitrile may be subjected to a preliminary fractional distillation to remove high-boiling impurities; and the water-rich side-stream withdrawn from the main column may be fed back into the preliminary column.  Crude acrylonitrile (made by catalytic reaction between acetylene and hydrogen cyanide) was distilled in a preliminary column; and water, higher acetylene polymers, cyanobutadiene and lactonitrile were withdrawn at the base. Acrylonitrile containing 0.5 per cent of divinyl acetylene was obtained at the head of the preliminary column, and this was fed to the main column.  This main column was a 8-cm. copper tube (2 metres high) filled with Raschig rings.  The inlet was half-way up the column, and water-rich liquid was withdrawn from a plate disposed 15 cm. above the inlet.  The head-temperature was maintained at 67-68 DEG  C.  Acrylonitrile (containing 0.15 per cent divinyl acetylene) was withdrawn from a level about 0.6 metres below the inlet.  This acrylonitrile was redistilled in another column, 0.3 per cent of water being added; and the divinyl acetylene content of the final product was thereby reduced to 0.02 per cent.

Title: Impact wrench having improved camming means
IPC: B25B21/02
Filed: 1967-07-13
Abstract: 1,120,159. Impact wrenches. CHICAGO PNEUMATIC TOOL CO. 13 July, 1967 [31 Aug., 1966], No. 32376/67. Heading B3N. [Also in Division F2] An impact wrench comprises a sleeve 25 driven by a sliding vane pneumatic motor 22, a hammer 33 splined in the sleeve, a cam shaft 45 connected to the hammer through a ball clutch, and an anvil 38 slidably connected to camshaft 45 by a key 51, or splines. A rotary impact is delivered at every alternate revolution of the anvil. Shaft 45, Fig. 11, has a ball track 62 comprising a lobe 73 which gradually falls away to a deep portion 67 extending for about 180 degrees, and then gradually rises up to the lobe. A raceway 64, Figs. 10, 11, extends around the cam shaft adjacent track 62, and has a symmetrical wide area 74 which extends for about 80 degrees on each side of the lobe. A radial stop 77 is provided, and guides ball 65 from area 74 into portion 67. Area 74 of raceway 64 has a relieved section 83. A track 63 in hammer 33 comprises a lobe 79, and a rubber ring 84 in the hammer engages ball 65 at some stage in the operation. In operation, motor 22 drives hammer 33, and ring 84 rolls ball 65 along track 62 until it drops into relieved section 83, whereupon it drops away from ring 84, engages lobe 79, thus providing a drive through hammer 33, ball 65, shaft 45, and nut engaging socket 42. When the nut is tight, hammer 33 rotates relative to anvil 38, and is accelerated towards the anvil by the ball cam 65, so that jaws 35, 43 engage to produce an impact. The ball is moved over lobe 73 by lobe 79, and rolls into area 74 of track 62. Spring 36 returns the hammer to the Fig. 1 position, whereupon ring 84 rolls ball 65 axially out of area 74, and stop 77 guides the ball back into track portion 67. Lobe 79 rides over the ball at a faster rate of rotation than that of the ball, and completes one revolution without producing an impact. However, during the second revolution of the hammer, the ball has been rolled into area 83 by ring 84, so that an impact is produced. The wrench operates in a similar fashion when the motor is reversed. In a modification relieved section 83 on cam shaft 45 is replaced by two slots 87, 88, Fig. 18, connected by a groove 89.

As shown, a finger-operated projection 12 slides a stop 9 on a flange 10 of the clipper shell to bring a stop 13 or 14 into engagement with the edge 15 of the flange 10 to limit the movement of the lever 7 so that the teeth 5, 6. of the movable comb 2 move through one or two intervals, respectively, of the teeth 3 of the fixed comb 1, leaving, in each case, some hair uncut. The stops may be adjusted so that it does not impede the stroke of the comb 2 and all of the hair engaged in the teeth 3 is cut. In a modification the stop comprises a rod extending through a screw-threaded cap which adjusts the pressure of a coil spring on the combs, the ends of the rod being - brought within a variable distance of a thrust washer through which the coil spring acts on a projection from the lever of the movable comb.
