Title: Improvements in or relating to counting mechanisms
Inventor: WHITE KENNETH GEORGE
IPC: G06M1/30
Filed: 1960-04-01
Abstract: 881,200. Zeroizing-mechanisms. ENGLISH NUMBERING MACHINES Ltd. April 1, 1960, No. 11560/60. Class 106 (1). In a counter in which the numeral wheels carry heart-shaped zeroizing cams, the zeroizing pawls are resiliently connected to a pawl-operating member so that after zeroizing; the disengaged transfer pinions are re-engaged while the pawls remain in contact with the cams, the numeral wheels being thus retained against undesired rotation after they have been zeroized. As described, a counter has four numeral wheels 1-4 driven by a driving pinion 7 and transfer pinions 18, the pinions being mounted on a shaft 8 carried on a carrier 22. The numeral wheels carry cams 21 adapted to be engaged by pawls 34 resiliently connected to pawl-operating members 29, the pawls and 34 pawl operating members 29 being formed as a unit 24 which may be of nylon. For zeroizing, the unit 24 is rotated clockwise (Figs. 3 and 5), a friction coupling in the form of a spring 38 causing the pinion carrier 22 to disengage the transfer and driving pinions. The pawls 34 bend due to their resiliency until they contact the operating members 29, whereupon continued clockwise rotation of the carrier 22 causes the wheels to be zeroized. During the anticlockwise return movement of the pawl unit 24, the pinions 7, 18 (Figs. 3 and 5) re-engage with the numeral wheel driving gears while the pawls 34 still remain in contact with the cams 21 thereby maintaining the numeral wheels against rotation.

Title: Process for accelerating the thorough hardening of masses made of casein and other protein substances
IPC: C08L89/00
Filed: 1931-04-20
Abstract: The hardening of proteins such as casein by formaldehyde is accelerated by the use of alkali metal salts, which are indifferent to the protein.  Masses or formed articles may be treated with the salt, preferably the chloride, and then with the formaldehyde bath, or the two may be applied simultaneously, e.g. 1-2 parts of a chloride may be added to 100 parts of a 10 per cent formaldehyde bath.  The salt may be added to the mass during its formation, as may also substances which subsequently liberate formaldehyde.  Mixed alkali metal salts may be used, and their action may be promoted by the addition of small quantities of acids or alkalies.ALSO:The hardening of artificial horn made from proteins such as casein, by formaldehyde, is accelerated by the use of alkali metal salts which are indifferent to the protein.

Abstract: 768,141. Electromagnetic relays. ALLIED CONTROL CO., Inc. April 23, 1954 [Jan. 4, 1954], No. 11786/54. Class 38(5) A relay comprises a U-shaped magnetic frame 12 having a core 19 upstanding from one edge of the frame base 22 and surrounded by a coil 11. A non-magnetic armature-carrying plate 13 is secured to the frame 12 by projections 31, 32 which are received in notches 24, 25, the core 19 extending through an opening 30 in the plate 13 to attract a plate armature 14. The armature is pivoted by a spindle 35 which passes through holes 34 in lugs 33 of the plate 13 and through loops 38 formed on the armature. That half of the armature which is situated on the same side of the spindle 35 as the core 19, overlies the ends of the frame arms 20, 21 whereby when the coil 11 is energized the armature tilts to close the flux paths between the arms and the core. The armature is balanced about the spindle so as to be insensitive to shock. The other, narrower half of the armature carries non-conducting pins 40. 41 which operate reversely-bent spring contact arms 59, 60 fixed to the inner ends of hook terminals 57, 58. The arms 59, 60 are biased downwardly so that when the relay is not energized they engage leaf contacts 63, 64 fixed to hook terminals 65, 66, energization of the relay causing the pins 40. 41 to lift the arms 59, 60 to leave contacts 63, 64 and engage the inner ends of a further pair of hook terminals 61, 62. The armature is additionally biased to its de-energized position by an adjustable coil spring (Fig. 7, not shown). The hook terminals are insulatedly carried by a metal top plate 46 fixed to the ends of prongs 48 on the plate 13. The pull-in and drop-out voltages of the armature are controlled by adjustable stops which limit the armature movement, outward movement being limited by a bushing 69 threaded in the plate 46 to engage the upper side of the armature; inward movement being limited by a stop 72 which engages the armature underside and is supported by a narrower stem 73 which extends through an armature slot 39, the upper end of the stem having a head 71 threaded into the interior of the bushing 69. A container 16 is soldered to the plate 46 and may be exhausted.

Title: Thermally responsive actuator
Inventor: WOODS JOHN EDGAR
IPC: G05D23/12
Filed: 1965-03-22
Abstract: 1,065,923. Temperature responsive actuating elements. STANDARD-THOMSON CORPORATION. March 22, 1965, No. 12068/65. Heading G1D. A thermally responsive actuator comprises a container 20, actuator means 22 within the container means and extending therefrom, thermalresponsive fill material 24 within the container and operable upon the actuator means, a portion 26 of the fill material being adjacent the actuator means, the fill material including polyolefinic material which is solid over a given temperature range, a second material mixed with said polyolefinic material, the portion of the fill material which is adjacent the actuator means having a smaller volumetric proportion of said second  material than does the remainder of the fill material. In the embodiment shown the actuator means is a piston 22 slidably engageable with the internal wall of the container 20. The thermalresponsive material is chosen so that it remains substantially solid over the operating range to obviate the use of a sealing member. Materials satisfying this requirement are polyethylene and polyprophylene. To provide increased expansion over the given temperature range a wax such as petroleum or mineral wax is mixed with the polyolefin. The resulting mixture has a high coefficient of expansion at the melting temperature of the wax but the wax does not separate from the polyolefin and so the resulting substance stays substantially solid. To provide increased expansion the proportion of wax may be increased but if more than 50% wax is used it is preferable to have a layer of polyolefinic material only next to the actuator mechanism. A variety of shapes of container may be used.
