Filed: 1968-05-10
Abstract: 1,200,984. Stripping moulded articles; cap liners. W. R. GRACE & CO. 21 April, 1969 [10 May, 1968], No. 22430/68. Heading B5A. Moulded articles, e.g. bottle cap liners, are removed from moulding apparatus comprising a two-part die and a further mould member, the two die parts being advanced together to the moulding position, but withdrawn therefrom separately, one acting to restrain the article against movement with the other during its withdrawal. As shown in Fig. 1, a die for moulding a liner in a bottle cap, &c. comprises a support 1 threaded to an outer die part 5 and an inner die part 10 passing through it and connected to a push rod 14, the inner die part being shaped as a poppet valve. Support 1 has cooling channels 26, 27 co-operating with an annular cooling chamber 28 in the outer die part 5. The die parts 5, 10 forming a continuous moulding surface 6, 12 are lowered by means of mould retainer 33, Fig. 2, into the moulding position over cap 44 containing a slug of moulding material and centred by recess 43 of cap holding member 37 to compress the slug into the form of a liner. On upward withdrawal of mould retainer 33 and outer die part 12 therewith, the inner die part 10 remains stationary due to rotation of cam 36 acting on the head of push rod 14, which clamps the cap and liner and causes stripping thereof from the outer die part 12. On further withdrawal of mould retainer 33, cam 36 returns to its original position and the inner die part 10 returns also, stripping the cap and liner therefrom, being restrained by cap holding member 37. Cam 36 is formed in a shaft (46, Fig. 3, not shown) passing through the retainer and keyed to a lever (48) which is only free to move clockwise from the horizontal. On downward movement, lever (48) pushes past the end (50) of another lever (51) free to move anticlockwise only, but on upward movement, lever (48), shaft (46) and cam 36 are forced to rotate clockwise by lever (51) until it clears the end (50) thereof.

Title: Improvements in or relating to refrigerating apparatus of the absorption type
IPC: F25B15/10
Filed: 1922-08-18
Abstract: 206,609. Siemens - Schuckertwerke Ges., and Altenkirch, E. Aug. 18, 1922. Refrigerating, absorption machines for. - Pumps in continuous-cycle apparatus for returning strong liquor to the generator are dispensed with by arranging the absorber 1 sufficiently above the generator 2 so that the column of liquid 114 compensates for the superior pressure in the generator and enables the liquor to flow under gravity. The system is described with reference to sulphuric acid and water. Steam from the generator, surrounded by a heating jacket 7, is condensed, on passing over a partition 101, in the condenser 13, surrounded by a cooling jacket 15. Some steam passes up the column 114 and induces circulation of the strong liquor from the jacketted absorber through the pipe 3 to the generator. Water vapour from the evaporator 19, which is jacketted by the liquid to be chilled, after passing over a partition 102 is absorbed in the liquid contained in the chamber 1. A rectifier may be arranged in the column 114. In the construction shown in Fig. 3, in which a rectifier 36 is arranged between the electrically-heated spiral generator 32 and the condenser 38, a capillary 40 is arranged between the ,rectifier and the absorber 30. Other capillary connections 56, 43 are arranged between the condenser and evaporator 54, and evaporator and absorber. A wide-bore vapour passage 57 is provided between the evaporator and absorber. The circulation between the absorber and generator is maintained against the superior pressure in the generator by the height of the liquid in the absorber above the mean height H of the liquid in the generator. Spherical buffer chambers 41, 48 are arranged in the circuit. Specification 199,366 is referred to.

Title: Angle-lock signal processing system including a digital feedback loop
IPC: H03D3/24
Filed: 1966-05-20
Abstract: 1,121,290. Frequency modulation receivers; automatic frequency control systems; transistor switching circuits. COMPAGNIE FRANCAISE THOMSON - HOUSTON HOTCHKISS BRANDT. 20 May, 1966 [21 May, 1965], No. 22649/66. Headings H3A, H3R and H3T. An input signal is combined with the output of a variable frequency oscillator 8, Fig. 5, in a mixer 2 to provide one input to a discriminator 4, the output of which is fed through an analogue and through a digital path to control the frequency of oscillator 8. If the system is intended to eliminate random frequency shift the output is taken from oscillator 8, but if the system is to receive frequency or phase modulation, e.g. from a satellite, the output is derived from the discriminator 4. The digital path comprises voltage discriminators 9 and 10 which produce outputs when their inputs exceed a given level positive and negative respectively, these outputs passing through OR circuit 50 to trigger a pulse generator 28, and also being applied to lines 35 and 37 respectively to control the counting direction of a reversible counter 30. The counter 30 produces an output voltage proportional to the stored count and this forms one input to a differential amplifier 13 controlling the frequency of oscillator 8; the other input is from the discriminator 4 through an integrating circuit 6. In a modification, Fig. 2 (not shown), the voltage discriminators 9 and 10 feed respective counters the outputs of which form inputs to a differential amplifier. In the receiver shown in Fig. 5, the input signal at aerial 1 is converted to intermediate frequency and amplified by an automatic gain controlled amplifier 46. When there is no input signal the noise output of amplifier 46 passes through diode 52 to gates 54 and 50, thereby causing the oscillator 8 to sweep; once a signal is found the A.G.C. cuts down the output of amplifier 46 so that it is insufficient to continue the sweep. Transistor switching circuits.-An input stage 20, Fig. 6, feeds two amplifiers 21 and 22 in parallel, the amplifier 21 responding only to positive inputs and amplifier 22 only to negative inputs. The output of amplifier 22 is inverted by stage 25 and the outputs of the two channels feed respective trigger circuits 23 and 24 which produce outputs on lines 106 and 108 respectively if their inputs exceed threshold values.
