Title: Fastener device for assembly in an aperture in a support
IPC: F16B5/12
Filed: 1962-12-07
Abstract: 1,012,703. Stud and socket fastenings. GOBIN-DAUDE S.A. Dec. 7, 1962 [Dec. 20, 1961], No. 46358/62. Addition to 981,676. Heading E2B. [Also in Division F2]  The fastener is similar to that described in the parent Specification except that the sleeve has a flange 28. For attaching a moulding strip 36, Fig. 5, to a support 34, a core pin 2 and a synthetic resin sleeve 4 with the flange 28 are located in a hole 38 in the support with an end 32 of the sleeve initially in a groove adjacent a dome end 10 of the pin. The strip 36 is placed on a head 8 of the pin with its edges 40 against end teeth 26 of the sleeve and then the strip and pin are pressed down to the position shown in Fig. 5. The strip 36 is then held on the flange 28 by the teeth 26 splayed by a surface 22 of the pin head 8 and the sleeve 4 is held by bulging 42 due to the action of the edge 14 (larger than the sleeve bore) of a conical expander portion 12 of the pin. The reduced end 32 of the sleeve is distended by an expander portion 16 of the pin 2. The outer diameter of the sleeve 4, including longitudinal ribs 30, is less than that, of the support hole 38.

Title: Improved clothes washing machine
IPC: D06F13/04
Filed: 1945-02-24
Abstract: 586,422. Washing-machines. CONSTANTINE, W. W. (General Motors Corporation). Feb. 24, 1945, No. 4669. [Class 138 (ii)] [Also in Group II] In a washing machine comprising a basket 10 rotatable about a vertical axis, limited lateral movement of the basket, due to an eccentric load, is counterbalanced by weights 16 rotatable with the basket and each pivoted on an axis parallel to the axis of rotation. As shown, a rubber or like collar 12 supports both the basket and a casing 11 containing the driving mechanism which is free to oscillate on the collar 12 and comprises a motor 20 adapted to drive, through transmission mechanism 23, a reciprocable and rotatable agitator shaft 14 and a rotatable shaft 24 carrying the basket. The weights 16 are pivotally secured by pins 18 to a ring 17 fixed to the shaft 24. Preferably, the bottom of the casing 11 is anchored by a flexible snubber 31 to the main frame 30 of the machine which consists of a casing having a central partition forming a trough 32. In operation, the clothes are placed in the basket 10 with detergent and water and the motor is operated to reciprocate the shaft 14 and thus the agitator 13. Thereafter, the motor is reversed to rotate the basket causing the water to be discharged centrifugally through openings 33, 34, into the outer cup 35 of the basket and over the lip 36 into the trough 32, from which it flows through a hose 37 to a pump 38 driven from the motor 20 and is discharged therefrom through a hose 39 into a drainage receptacle. Rinsing water is then introduced into the basket 10 and the agitating and rotational operations repeated, any unbalanced load produced by uneven distribution of the clothes being counterbalanced by the weights 16. The weights may be flexibly pivoted on the pins 18 by means of interposed rubber or like sleeves or may be connected to the ring 17 by light springs, and stops 17a are provided to limit their movements.

Patent GB-891232-A (GB)
Title: Apparatus for measuring lengthwise tension in a strip
IPC: B21B38/06
Filed: 1959-02-11
Abstract: 891,232. Measuring tension. BRUCKER, H. Feb. 11, 1959, No. 4807/59. Class 40 (1). [Also in Group XIX] In apparatus for measuring the tension in a strip 5 running over a deflecting roller 7 and on to a winding-on reel 8, the tension is calculated from the force applied to the roller 7 and the geometrical magnitudes of the triangle formed by this roller and the strip tensioning points W, A on either side of it, and means 10 being provided to measure the changes in position of the point A. As shown in Fig. 4, the deflecting roller 7 is supported by a piston 23 in a cylinder 24 to which air under pressure is supplied, and the force applied to the roller is calculated by the deflection of a leaf spring 19 to which a strain gauge 21 is secured, the resistance of which increases when the spring 19 is bent. The size of the winding reel 8 is measured by a spring-urged feeler roller 26, the position of which is measured electrically, e.g. by a potentiometer 30. These two values are then electrically combined to produce a reading corresponding to the tension in the strip 5. In the embodiment shown in Fig. 1, the outside diameter of the reel 8 is determined by a roller running on the surface of the reel, and the force exerted on the roller 7 is measured by means incorporated in its bearing. In a third embodiment (not shown), the roller 7 is supported on a pivoted arm which takes up a position bisecting the angle between the two runs of the strip on either side of the roller 7. The angular position of this arm is measured electrically and the force acting on it is measured by the extension of a strain gauge. These measurements are combined electrically to give an indication of the tension in the strip. The device can also be used for measuring the tension in strip being unwound from a reel.

Title: Recovery of d-arabitol
Inventor: PODMORE WILLIAM DENIS
IPC: C12P7/18
Filed: 1957-02-13
Abstract: When d-arabitol is recovered from fermentation broths by reducing the volume of the broth by removal of water followed by extracting with normal- or iso-butyl alcohol, any glycerol present is also extracted by the alcohol and may be recovered by any suitable means from the mother-liquor after the d-arabitol has crystallized out.  In the example, a fermentation medium containing molasses, urea, corn-steep liquor, and invertase enzyme is fermented with an osmophilic strain of saccharomyces isolated from brood comb pollen; n-butanol is added to the fermentation broth, the mixture is distilled until it is reduced to one-third of its original volume, the organic layer is separated, d-arabitol crystallizes out and is filtered off, and the mother liquor is subjected to steam distillation under reduced pressure to give glycerol.  Specification 822,154 is referred to.ALSO:D-arabitol is recovered from fermentation broths containing it by a method comprising reducing the volume of the fermentation broth by the removal of water, extracting the concentrate thus formed with normal or iso-butyl alcohol and recovering d-arabitol from the alcoholic extract.  Preferably the fermentation broth is obtained by the fermentation of a suitable nutrient medium by the organism Saccharomyces rouxii or Saccharomyces mellis.  The volume of the broth may be reduced by evaporation at low temperatures under reduced pressure.  Preferably the volume is reduced by azeotropic distillation in the presence of butyl alcohol which forms an azeotrope with water.  The mixture remaining is then allowed to separate, the alcoholic layer is removed and may be concentrated.  On cooling the d-arabitol crystallizes out from the alcohol.  It is desirable to complete the extraction above 103 DEG  C. The crystals obtained may be purified by washing, for example, with acetone and by re-crystallization from butanol or methyl alcohol in the presence, if desired, of active carbon.  When the fermentation broth contains glycerol this is also extracted by the alcohol and may be recovered from the mother-liquor after the d-arabitol has crystallized out by any suitable means (Group III). In the example, a fermentation medium containing molasses, urea, corn steep liquor and invertase enzyme is fermented with an osmophilic strain of Saccharomyces isolated from brood comb pollen; n-butanol is added to the fermentation broth, the mixture is distilled until it is reduced to one-third of its original volume, the organic layer is separated and the d-arabitol crystallizes out from the n-butanol.  It is purified by recrystallization from n-butanol in the presence of active carbon. Specification 822,154 is referred to.

Title: Improvements in skew axis gearing
IPC: B23F11/00
Filed: 1955-02-18
Abstract: 805,482. Toothed gearing. ILLINOIS TOOL WORKS. Feb. 18, 1955 [Feb. 18, 1954 (2)], No. 4988/55. Class 80 (1). [Also in Groups XXII and XXIII] A method of making a skew axis gearing consists in cutting identical threads in a worm and a hob blank, and using the hob to cut teeth on a gear blank to mesh with the worm, the thread cut on the worm and hob being such that it follows closely the relative velocity vector spiral. To cut the thread, a tool 90 is mounted on a radially-adjustable slide 91, by which the tool is kept at the correct cutting depth. The arm is rotated by a shaft 50 which is adjustably geared to a shaft 40 carrying the work 20. The machine may be set up to cut a spiral having a predetermined lead, curvature, and change of curvature at one transverse plane of the work to correspond to the relative velocity vector spiral at that plane which is preferably mid-way between the ends of the gear. (The movement of the tool is a sinusoidal function of the rotation of the work, which fact renders simpler the mathematical calculations, which are referred to in the Specification.) The resultant thread spiral differs only slightly from the theoretical vector spiral. The method may be used to cut gears with the axes not at right angles, and to cut worms which are not conical. The worm differs from that described in Specification 774,128 in that the lead is not constant.

Abstract: 915,268. Valve-gating circuits. POSTMASTER GENERAL. Feb. 10, 1959 [Feb. 17, 1958], No. 5077/58. Class 40 (6). [Also in Group XXXIX] In a voice-frequency signalling system which includes a buffer amplifier in the receive path of a 4-wire circuit, the effect of the surge produced in the anode circuit of the amplifier when the latter is split is reduced or eliminated by the production of an equal and opposing surge, composite negative feedback being used to stabilize the gain of the amplifier and to achieve the desired output impedance. In the arrangement shown, the amplifier is split by the grounding of the cathode of V1 by contact S, the auxiliary winding L1 of the output transformer thus producing in the load RL a surge equal and opposite to that produced by the primary (anode) winding P1. The amplitude of the surge produced by L1 is controllable by varying the value of resistor R1.
