Title: Improvements in or relating to counting systems
IPC: G06M7/00
Filed: 1964-07-13
Abstract: 1,041,126. Counters. BROOKHIRST IGRANIC. July 13, 1964 [Oct. 2, 1963], No. 28746/64. Headings G4A and G4D. In the counting of spaced articles the counter is rendered inoperative after an article has been counted but is restored to operative condition before the next article can pass, whereby false counts are prevented. In counting overlapping newspapers the contacts 2 are most likely to bounce in the distance D, Fig. 2, immediately following detection of a leading edge. This distance corresponds to the passage of five teeth A of wheel 8. Detection of a leading edge therefore flips flip-flops 3, 4 to add one to counter 7. Flip-flop 4 inhibits flip-flop 3 and opens gate 14 so that the teeth A send alternate +ve and - ve pulses to decade counter 15. At a count corresponding to distance D, counter 15 restores flip-flop 4 which then inhibits gate 14 and releases flip-flop 3, which is then able to respond to detection of the next newspaper. Decade counter 15, Figs. 1 and 6. Oppositely phased pulses T, U are applied to terminals 63, 64 in turn. With transistors 127, 129, 131, 133 initially conducting in stages 15a, 15b, 15c, 15d, the first pulse, on terminal 63, cuts off 127 and turns on 128. The second pulse, on terminal 64, restores stage 15a, the resulting pulse from the collector of 127 acting through capacitor 164 to reverse stage 15b. The fourth pulse restores stage 15b, this time through capacitor 166 and a resultant pulse turns on 15c. In like manner the eighth pulse turns on 15d. Negative potential from the collector of 133 now biases rectifier 185 to render stage 15b inoperative to the tenth pulse which results in a pulse applied through capacitor 182 to restore stage 15d. The resultant positive pulse from the collector of 133 passes to output 65.

Abstract: 821,786. Coin-freed vending apparatus. LUCKENWALDER METALLWARENFABRIK VEB. Sept. 12, 1957, No. 28828/57. Class 27 In a machine for vending articles from columns of separate compartments each closed by a door 1, the door is held locked by a solenoid armature spring-loaded into a hole 3 in a plate 2 and, on insertion of a coin and operation of a pushbutton 9 at the selected compartment, the corresponding solenoid 5 is energized to allow the door to spring open but the current to the other solenoids is interrupted. The inserted coin momentarily actuates a switch 16 and a relay 17 is energized to supply current to the pushbutton switches 13 through contacts 18, 19 and 20. Operation of a selected pushbutton then changes over switches 13, 14 so that current is supplied to the appropriate solenoid but is cut off from the others. As the door opens, the top edge of the plate 2 allows a wiping contact 8 to close momentarily the circuit of a magnet 15 which releases the coin or coins to a central coin box and at the same time opens the contacts 19 so that the relay 17 is de-energized. For refilling the compartments, contacts 21 operated by a lock supply current to the pushbutton switches without insertion of coins.

Title: Improvements in or relating to silicone polymers
IPC: C08G77/00
Filed: 1946-10-02
Abstract: A partially dehydrated silanol polymer is dissolved in more than three times its weight of inert solvent and is further dehydrated intramolecularly using a mineral acid dehydrating agent.  The treated polymer yields on further polymerization to the solid state a stabilized silicone having reduced shrinkage when heated, greater solubility in non-polar and lesser in polar solvents, and smaller electrical losses than untreated silicones. Suitable dehydrating agents are 65-90 per cent sulphuric acid, 70-85 per cent phosphoric acid or phosphorus pentoxide in a suitable carrier.  Vigorous stirring is desirable during the treatment to ensure intimate contact between the silicone and the dehydrating agent.  Examples describe: (1) and (2) treatment of an intermediate methyl phenyl silicone polymer with sulphuric acid of various concentrations in toluene solution.  Comparison is made with untreated polymers.  Progressively stronger solutions of sulphuric acid may be applied in stages; (3) treatment in toluene solution with strong sulphuric acid of an intermediate polymer prepared by hydrolysis with weak sulphuric acid of a mixture of dimethyl silicon diethoxide and methyl silicon triethoxide.  The product was mixed with an oxidation inhibitor and dioctyl phthalate and polymerized to a solid; (4) treatment with strong sulphuric acid of a toluene solution of an intermediate polymer prepared by co-hydrolysis of dimethylsilicondiethoxide, methylsilicontriethoxide, and phenyl silicon triethoxide.  Mention is made of intermediate silicones of formula Rx Si(O/2)y (OH)4-(x + y) where R is aliphatic or aryl or both, e.g. ethyl, methyl, allyl, phenyl or tolyl, x = 1 to 3 and y is 1 or 2.

Title: Gear coupling
IPC: F16D3/18
Filed: 1966-06-30
Abstract: 1,112,283. Universal joints. SIER-BATH GEAR CO. Inc., and E. WILDHABER. 30 June, 1966, No. 29430/66. Heading F2U. In a. gear-toothed coupling, wherein internal longitudinally straight teeth 13 of a sleeve (12) engage external longitudinally convexly crowned teeth 15 of a hub (14), the crowning of the sides of the teeth 15 is increased adjacent both ends of said teeth by abruptly changing the radius of crowning curvature, to provide for abovenormal angularities, between the sleeve (12) and the hub (14), occurring under little or no. intended. load, e.g. on assembly. The top lands of the hub teeth are spherical. At maximum normal shaft angularity under full load the centre of the contact zone is at a point 24. The abrupt change in radius of crowning curvature starts at a point 30 which is spaced from the point 24 at about half the width of said contact zone centred at point. 24. The normal working portion, 30-30<SP>1</SP>,of the crowning may, as shown, be of approximately constant radius; may, Fig. 4 (not shown), be of gradually increasing radius from the centre (e.g. a hyperbola) so as to increase surface capacity with increasing angularity, to offset the decreased number of teeth in contact and increased sliding; or may, Figs. 5, 6 (not shown), comprise two branches intersecting at a central ridge (54), this form being for a coupling intended to operate at an angularity only. The inclination of the crowned tooth profile in planes perpendicular to the hub axis, and at points equidistant from the hub axis decreases from the tooth centre to the ends. The increased crown portions are widest adjacent the tooth root. The profiles at the centres of the external teeth crowns match those of the sleeve teeth, as shown, and. in Fig. 4 (not shown). The profiles of the central ridges (54) of Figs. 5, 6 (not shown), touch the corresponding sleeve teeth profiles only adjacent the roots of the latter, inwardly tapering surfaces connecting the otherwise intersecting branches being necessary if profile matching is required in this embodiment. The crowning is mechanically produced by uniform feed of a hob along the hub axis with an additional feed in the depthwise direction to obtain the resultant curved feed. This additional feed is controlled by a templet the ends of which may be cut off at an obtuse angle so as to produce, in co-operation with an arcuate abutment, the increased crowning. The profiles of the straight teeth 13 are concavely curved, e.g. involute. A seal (17) is provided for lubricant retention.
