Title: Improvements in Coin-freed Mechanism for Gas Meters and the like.
IPC: G07F15/08
Filed: 1916-04-12
Abstract: 106,294. Cockey, F. G., and Gas Meter Co. April 12, 1916. Gas, supplying by meter; price-changing mechanism. -A price-change disk g rotated by a coin in a coin-carrier c is coupled by means of a pawl h, Fig. 5, to a ratchet-wheel i of the quantity mechanism. A radial arm n, Fig. 3, bearing a projection n<1> is adapted to be secured in notches o in the disk g; the carrier c, during its return movement, restores the disk g to the initial position by engaging the projection n<1> and moving back the arm n to a fixed bracket k. To enable the valve to be closed and the quantity mechanism zeroized by hand, the spindle j of the ratchet i is provided with a slot j<2> for a screw-driver; an aperture m in the disk g gives access to the pawl l of the ratchet i. Coin action, mechanical connexion.-The coin carrier c is rotated by means of a spindle d, which has a limited independent movement in the carrier, being provided with an arm d<2> adapted to pass through a slot c' in the wall of the carrier into engagement with the coin. As the carrier rotates, the projecting coin strikes an arm h<1> of the pawl h, Fig. 5, which is mounted on the disk g, and turns the pawl into engagement with the ratchet i. To prevent reversal of the carrier before the coin has been discharged, the spindle d is provided with a cam e which serves to raise the coin into engagement with a fixed rack f; or the pawl h may be held in engagement with the ratchet i by a detent h' an arm h<2>, Fig. 3, of which is engaged by the coin if reversal of the carrier is attempted. The cam e also assists in discharging the coin.

Title: Improvements in or relating to electric frequency discriminators
Inventor: STARR ARTHUR TISSO
IPC: H03D9/04
Filed: 1948-02-24
Abstract: 641,915. Frequency and phase modulation. STANDARD TELEPHONES & CABLES, Ltd. Feb. 24, 1948, No. 5405. [Class 40 (v)] Relates to discriminator networks designed to give linear response over a wide deviation band, such as are required in multiplex systems employing a wide band of signal frequencies, and consists in employing resonant transmission lines as network elements, and in feeding the F.M. wave to the lines through valves delivering constant current. In a known arrangement shown in Fig. 1, the F.M. wave is fed to input terminals 17, 18 of unilateral devices 19 such as pentode valves of high internal impedance, the output circuit of which comprises parallel combinations of inductance, capacity and resistance I, 2, 3, 4, 5, 6. Each of these combinations feeds a rectifier 7, 8, a load resistor 9, 10, and a byepass condenser 11, 12. The Specification indicates the necessary relationships between the elements of the network in order that the equation connecting the output at 13, 14 with the frequency deviation may be a linear one, design formulµ being given which result in elimination of the quadratic term, leaving only negligibly small terms involving cubic and higher powers. According to the invention, the resonant circuits of Fig. 1 are replaced by lengths of coaxial line 43, 55 as shown in Fig. 3, in which these elements together with resistors 42, 56 are arranged in the anode circuits of pentode valves 31, 32 fed in parallel with the received F.M. wave. If the lines 43, 55 are of length #/8 and one is shortcircuited and the other open-circuited at their outer ends, and if the resistors 42, 56 are given a suitable value higher than the characteristic impedance of the lines, both the quadratic and the cubic terms of the equation representing the frequency characteristic can be eliminated. The presence of capacities across the resistances 42, 56 may be compensated by making the lines 43, 55 of different lengths. In Fig. 3 the voltages produced across the frequencydiscriminating networks are rectified by diodes 44 connected to load resistors 46 through lowpass filters 45. The load resistors are connected across grids and cathodes of amplifiers 47, 51 and the detected signal is taken across the respective anodes at terminals 29, 30. Germanium or other rectifiers may replace the diodes 44. The discriminator may be employed in a F.M. transmitter by feeding the modulated wave to the discriminator through a frequencychanging stage, and passing the discriminator output as a negative feed-back to the input of the modulator (Fig. 4, not shown). Specification 641,916 is referred to.

Title: Opening crimped filamentary tow
IPC: D02G1/20
Filed: 1962-02-14
Abstract: 1,001,813. Opening crimped tow. CELANESE CORPORATION OF AMERICA. Feb. 14, 1962 [Feb. 21, 1961], No. 5637/62. Headings DiD and D1F. Crimped tow of artifical filaments is opened and the crimps in individual filaments moved out of registration with those in adjacent filaments by passing the running tow between a pair of rolls at least one of which has grooves and ridges in its surface running at an acute angle to the axis of the roll (and may be driven) so that filaments are only gripped between the rolls at the ridges and little or no grip is applied to the remaining filaments, whereby successive sections of the tow across its direction of movement are gripped and released and at the same time some filaments move laterally relative to other filaments. Crimping may have been effected by passage of the tow through gear wheels or a stuffer-box. The filaments may be of regenerated cellulose, cellulose esters or ethers e.g. acetate or triacetate, polyacrylonitrile, polyamides or polyesters, and the total denier may range up to 160, 000. The opened tow may be made into filter, "non-woven" and/or bonded and/ or multi-layered mats or fabrics, or bulky yarn. One roll may have a smooth surface and the grooved roller is biased theretowards. If both rollers are grooved, the opposing grooves may run in the same or opposed direction provided there is no registry between the ridges on one roller and the grooves in the other e.g. rolls are of different diameter or rotated at different peripheral speeds or one or both reciprocated axially. The grooves are helical or parallel and endless and each roll may have two grooves or sets thereof of opposite sense running from the centre of the roll to each end, Figs. 4 and 5 (not shown). Spaced pairs of rolls may act successively and at progressively increased or decreased speeds on the tow. In the operation of the apparatus shown in Figs. 1 and 3, crimped tow 11 withdrawn from a bale 12 is fed through a straightening device 13, to remove folds and prevent twisting of the tow, and a compressed air jet 14, to flatten the tow. The band of filaments passes over guides 15 and 16 and through an opening mechanism comprising pairs of rolls 17 and 18, 19 and 20, 21 and 22, the lower rolls being driven with any predetermined speed differential from mechanism 31 through chains 34, 37 and 40 and sprockets 33, 35, 36, 38, 39, 41. Modified apparatus, Fig. 6, includes tension rolls 52 and 53 which smooth out crimp variation. These rolls may have smooth surfaces of elastic material such as rubber and be positively driven or rotated by the drag of the running tow.
