Title: Improvements in comparators
IPC: G01B3/56
Filed: 1944-09-28
Abstract: 585,740. Angle gauges. CLEMENT, F. R., and ANDREWS, W. W. Sept. 28, 1944, No. 18529. [Class 97 (iii)] [Also in Group XIX] A comparator for comparing or measuring angles or tapers of work-pieces comprises a base 1, a main frame 2 pivotally mounted thereon and having means 40, 42 to effect fine adjustment relatively to the base, an arm 3 pivotally mounted at 13 on the frame 2, the free end 21 of the arm being in contact with the push-rod 12 of an indicating means 5, the pivot end 13 of the arm carrying means for holding a work-contacting member 4, and means for adjusting the member 4 relatively to the arm 3. The frame 2 is of channel form with a cover-plate to receive the arm 3, has a boss 6 to receive the indicator 5, and carries the pivot pin 13 on which an externally screwthreaded sleeve is freely mounted thereon. A knurled nut 16 engaging the sleeve clamps the shank 17 of a yoke 18 carrying the member 4. The member 4 may be a straight-edge as shown in Fig. 1, or as shown in Figs. 7 and 9 for testing the angles of bevel gears. The free end 21 is an adjustable extension of the arm 3 and carries a hardened steel ball 24 engaging the end of the rod 12. A lug 28 of the frame 2 is mounted on a pivot pin 31 on an intermediate bracket 30 and clamped thereon, and the latter has a lug pivoted on a pin 44 in cheeks 46 of the base 1 and is clamped by a lever. nut 47 to the cheeks. The fine-adjustment means 40, 42 enable the frame 2 to, be adjusted relatively to the bracket 30. The base 1 has a finger-grip recess 51 and a registering pad 52 at each side, and a V-shaped recess formed on the underside.

Title: Film winding gearing for cinematographic apparatus
IPC: G03B21/43
Filed: 1972-04-21
Abstract: 1332110 Ratchet mechanism FRANKE & HEIDECKE GmbH 21 April 1972 [24 April 1971] 18668/72 Heading F2Q [Also in Division G2] Film winding gearing includes a shaft 1 carrying a ratchet wheel 2, two diametrically opposed pawls 4, 5 on a pawl carrier 3 and a mechanism for rocking the pawls 4, 5 so as to step the ratchet wheel 2 and which does not over tension the film being wound. As shown in Fig. 1, the pawls 4, 5 are pivoted on pins 6, 7 urged by springs 8, 9 to contact the wheel 2. The rocking of the pawls is performed by a pin on lever 19 following the groove 23 on shaft 24. A pin 20 on lever 18 thus rocks the pin 14 on the pawl carrier 3 by means of the jaws 15, 16 pivoted at 17 and biased together by spring 21. To prevent over tensioning the film, the spring 21 absorbs the motion of the pin 20. Hence film tension is controlled without impeding rotation of the shaft 24. In Fig. 2 (not shown), the pawls are formed integrally with a ring pivotally mounted on a part similarly constructed and mounted as the carrier 3 in Fig. 1. The remainder of the mechanism is identical to Fig. 1.

Title: Safety belt
IPC: A44B11/25
Filed: 1965-05-04
Abstract: 1,107,911. Belt buckles. H. SCHOCK. 4 May, 1965, No. 18758/65. Heading E2A. A safety belt buckle comprises a slider 2 adapted to be attached to a safety belt strap and a latching mechanism 1 adapted to be secured directly to the body of a vehicle in which the safety belt is to be used, the latching mechanism including a latching member 7 in the form of a rotatable and axially displaceable pin which engages an aperture in the slider, means 8 to urge the pin to the latching position in which it engages said aperture, a manually operable lever 9 connected to the pin and a cam surface 10 which cooperates with the lever such that on moving the lever so as to rotate the pin, the pin is also displaced axially and the slider is released. In the construction shown the latching mechanism comprises a housing consisting of two portions 3, 4 which are connected to one another by screws 5. The portion 3 is provided with an extension 3a by which the latching mechanism is fixed to the vehicle body through holes provided in the extension; the extension is either inclined at an angle to the remainder of the portion 3 in which case the latching mechanism is intended to be fixed to a horizontal portion of the vehicle body or alternatively the extension is aligned with the remainder of the portion 3 in which case the latching mechanism is intended to be fixed to a vertical portion of the vehicle. The housing portion 3 has a tubular extension 3b which serves as a bearing bushing for the latching member 7. The member 7 is biased by a compression spring 8 against the housing portion 4 and it has an inclined surface 7a' which is engageable by the slider when it is inserted into the housing to raise the member 7 against the bias of the spring 8 until an aperture in the slider becomes aligned with the member 7 which then drops into the aperture to secure the slider to the latching mechanism. The member 7 is removed from the aperture by rotating the lever 9 and this rotation brings the lever 9 into engagement with two said cam surfaces which are in the form of V shaped notches in the extension 3b; the cam surfaces raise the member 7 against the bias of the spring 8. An ejector spring 14 is located between the two housing portions for ejecting the slider 2 from the latching mechanism when the member 7 is in releasing position. In a modification the bearing bushing instead of being an extension 3b of the housing portion 3 is a separate member secured between the housing portion 3 and a cap.

Title: Improvements in or relating to the recovery of aluminium from aluminium-containing material
Inventor: JOHNSTON ALAN HUTCHISON
IPC: C22B21/00
Filed: 1959-06-04
Abstract: In a process for obtaining aluminium from granular aluminium-bearing materials by treatment with aluminium halide the charge in the reaction zone is heated by the passage of electric current, and incoming charge is preheated either to the reaction temperature or to the upper limit of the range over which the charge material has a negative temperature coefficient of resistance, whichever temperature is lower.  Pre-heating may be carried out either by external heating i.e. not by the passage of current through the charge, or by the exothermic partial decomposition of the aluminium subhalide formed in the reaction zone, the reaction products being passed through the charge to be preheated.

The evaporation is carried out under vacuum and so that the evaporative and heating surface of the material is large relative to its volume. The water content is preferably reduced to 15-25 per cent by weight. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of chemical or alimentary equivalent substances .in place of the sodium chloride, cane sugar and lactic acid. This subject-matter does not appear in the Specification as accepted.

[Also in Division F1] In a rotary-piston engine of epitrochoidal type, to control the planetary rotation of the piston so that the speed of the output shaft is reduced to that of the piston without the fitting of reduction gearing, a member 2, Fig. 2, secured to the output shaft 1 is formed with three equally spaced arms slidably mounting shafts 7 each carrying a planet gear 10 meshing with a spur gear 12 secured to the side part 3 of the casing 4. Each shaft 7 is formed with an eccentric 17 slidable in a bore 8 in the piston 9 which is independently mounted on the output shaft 1. Instead of the gearing 10, 12 and the member 2 being adjacent one another on one side of the piston as shown, they may be symmetrically arranged on opposite sides of a central piston flange. In an alternative embodiment, the eccentrics 17, Fig. 8 are slidable in parallel bores in a member separate from the piston located outside the thermal area of the engine but positively connected to the piston. Instead of the eccentrics 17 the shafts 7 may be cranked. To take up any backlash that may arise after a period of use on the tooth flanks, the spur wheel 12 is formed with a flange which is secured to the side part 3 by means of bolts 14 adjustable with respect to arcuate slots in the flange.
