Abstract: 1525079 Substation apparatus STOPPANI S A ETABS POUR LA MECANIQUE DE PRECISION ET L'ELECTRO-MECANIQUE and OLIVER TECHNIK AG 23 July 1976 [31 July 1975] 30857/76 Heading H4K An apparatus, for connecting a telephone line to a calculator having a printer and a display, comprises means for separately detecting dial and charge pulses, processing means for recognizing dialled digits and counting charge pulses and control means for issuing instructions to the calculator for printing each dialled digit, displaying the current charge of a call and upon termination of the call for printing the total charge. In the embodiment a unit 401 receives data from the line and detects separately the digit pulses of a dialled number and the charge pulses. The digit pulses are supplied to a processing unit 301 which has delay circuits for distinguishing true dialling pulses from momemtary interference pulses. Unit 301 detects the end of each pulse train forming a digit and also the end of a call. The charge pulses are supplied to a unit 402 which generates the charge-calculation and charge-printing-order sequences. It also receives two signals from unit 301; DCR (end of call) and FUH (inter digit pause). On reception of a charge pulse unit 402 generates instructions for the charge unit to be added to the charge indicated by the calculator. These instructions are supplied to a unit 302 which also receives the dialling data from unit 301 and through an interface 303 instructs the calculator. During dialling unit 302 counts the pulses in each digit and transmits the numerical value of the digit and the instruction to "PRINT" to the calculator. At the end of this printing sequence unit 302 transmits the orders generated by unit 402 for the display and printing of the charge. Unit 302 also includes an oscillator which can operate in two frequencies, a low and a high frequency, for timing the orders sent to the calculator; the high frequency is used when the charge pulses are to be added and displayed and the low frequency when the dialled number and the total charge are to be printed. Unit 303 comprises gates which are connected across the key contacts of the calculator, through a multiple plug (5, Fig. 1, not shown), and they simulate pressing of the keys by shorting the respective contact of each key when ordered by unit 302. A plug (4, Fig. 1) connects the apparatus to the telephone line, another plug (3, Fig. 1) connects it to a power supply and a lamp (305, Fig. 1) indicates when the apparatus is in use, so that the calculator may not be used in its normal operating mode, i.e. calculating.

Title: Improvements in or relating to multiple track sound-film recording
IPC: G11B7/00
Filed: 1936-08-06
Abstract: 479,083. Optical sound -. recording apparatus ; light valves. WESTERN ELECTRIC CO., Ltd. (Electrical Research Products, Inc.) Aug. 6, 1936, No. 30861/37. Divided out of 479,070. [Class 40 (ii)] [Also in Group XL] A light valve for use in the production of multiple - track soundfilm records comprises a plurality of pairs of vibratoryribbons mounted in a single magnetic system and illuminated by a single light source, each pair of ribbons being adapted to produce a separate record on the film. In the construction shown, for producing a, double-track variable-density record, two pairs of ribbons 155, 156 and 158, 159 are disposed between the poles 105, 106 of a magnet, in which are formed opposed slits 135, 126 and 136, 127 for the passage of the recording light beams. As shown in Fig. 7, the ends of the ribbons are attached to supporting members 160, 161 ... 167, capable of being moved transversely by screws 181, 183, ... to adjust the relative spacing of the ribbons, and of being moved longitudinally by screws 184, 189 to vary the tension thereof. In order to reduce the possibility of the ribbons shearing at the supports 163, 164, triangular portions 212, 213, are removed from the pole faces to effect a reduction in the intensity of the magnetic field. The light rays are brought into transverse alignment on the film F, Fig. 11, by means of angularly disposed refracting members 200, 201, mounted in a holder 203 in the portion 119 of the valve structure. For monitoring purposes, slits 137, 128 and 138, 129 are formed in the magnet pole faces, in alignment with the recording slits, the light beams being deflected to the exterior of the valve by the bevelled ends of metal-sheathed quartz rods 146, 147, Fig. 5, mounted on the pole face 106. Instead of using separate recording and monitoring slits, single slits may be formed of such a length as to include the areas of the separate slits. When the valve is utilized for the production of variable width records, the vibratory ribbons are mounted so as to be parallel to the direction of motion of the film, in which case the tracks may be of equal or unequal widths. For the production of push-pull records, the ribbons are connected in series, and for split-frequency records, currents of the desired frequency ranges are fed to the individual pairs of ribbons, the tensions of which are so adjusted that they operate at their maximum efficiency when subjected to such currents.

Abstract: 805,719. Converting reciprocating into rotary  motion. OWENS-ILLINOIS GLASS CO. Oct. 13, 1956, No. 31238/56. Class 80 (1). Step-by-step rotation is imparted to a member such as the table 18, Fig. 1, in a glass bottle moulding machine by means of a reciprocating rack 23 engaging a pinion 24 which is periodically coupled to and uncoupled from a disc 25 on the shaft 19 of the table by axial movement of a pin 26 automatically operated in synchronism with the rack. The rack 23 is actuated by a hydraulic motor 22 and during each rearward stroke imparts 120-degree steps to the table 18. The pin 26 is actuated by axial movement of a shaft 40 passing through the hollow shaft 19 and connected by a lever 44 to a piston 45, the pin 26 carrying a roll engaging an annular recess in a member 41 on the shaft 40. When the pinion 24 and disc 25 are uncoupled the disc is locked against rotation by a detent 35 actuated by a hydraulic motor 36. The hydraulic system is controlled by valves 50, 51 actuated by cams 55, 56 on a shaft 57 geared to a motor 58. In Fig. 3, the cams 55, 56 are so positioned that the rack motor 22 is at the end of its idle forward stroke, the piston 45 having been raised to lower the shaft 40 and thus uncouple the gear 24 and disc 25, and the detent 35 having been projected to lock the disc 25. To effect these conditions the valve 51 has connected a pressure chamber 67 to the lower end of motor 22 while the valve 50 has connected a pressure chamber 60 firstly to a piston 47 which has raised the piston 45 and secondly to a piston 62a in the motor 36 which has projected the detent 35. As the cam 55 moves the valve piston 63 to the left the pressure chamber 60 is connected to a piston 48 which lowers the piston 45 and consequently couples the gear 24 and disc 25 together. Simultaneously pressure on a large piston 65a in the motor 36 overcomes the piston 62a and retracts the detent 35. The cam 56 then moves valve piston 66 to admit pressure to the upper end of motor 22, via the piston 45. The rack 23 is consequently moved rearwardly to rotate the table 18 through 120 degrees, whereafter the cams 55, 56 return the valves to the Fig. 3 positions to complete the cycle. The table 18 successively brings neck moulds 17 to a blank mould station A and blanks 14a to a finishing mould station B. At the station A a blank mould 10, into which charges of molten glass are dropped, is periodically lifted by a piston motor 11, a press plunger 14 being actuated by a piston motor 16. At the station B partible mould sections 30 operated by a piston motor 32 swing about a pivot 31 to close about the blank 14a suspended from its neck mould, and a blowhead 33 is lowered to blow the blank to its finished form.

In an hydraulic control system for the change-speed gear of a motor car, ratio-shift valves are operated according to the pressure developed by an output-driven governor valve, with accelerator-pedal-kickdown operating a valve in a control pipe for downshifts and modulation of the ratio-shift speeds as sensed by a valve 144 actuated through a diaphragm servo 150 connected to engine-inlet-manifold depression, the compression of a spring 200 against which inlet-manifold depression acts being varied by adjustment of an externallythreaded bush 196 to compensate for tolerances in manufacture causing the speeds at which ratio shifts occur to exceed or fall below acceptable limits. The spring 200 is held in a cup-shaped retainer 202 abutting the threaded brush 196, and is thus compressed &c. as the bush is turned. The valve 144 is slidden by a rod 186 engaging the diaphragm servo 148. The servo 150 is in use connected to the engine inlet manifold by a pipe mounted on a pipeend 192 welded to the end of the servo body 150 and threaded internally to receive the bush 196. To adjust the bush 196, the inlet-manifold connecting pipe is removed and is replaced by and adapter 208 connected to a source of vacuum 228, simulating inlet manifold depression. A wrench 218 passing into the adapter 208 has an hexagonal head 220 received in a corresponding hole in the threaded bush 196. A pressure gauge 236 &c. is secured to the outlet ports 172 of the valve 144 actuated by the servo, and the effect on the valve obtained by adjustment of the threaded bush 196 is thereby determined. The system is described applied to the control of a two-reduced-ratio, direct-drive and reverse ratio overlapping multiple train planetary gear driven through an hydrodynamic torque converter. The gearing is similar to that described in Specification 704,787 (Group XXIV), wherein two sun gears mesh intermeshing planet pinions in a carrier which can be stationed by a band brake, the planet pinions meshing an output ring gear, the gearing also including the feature described in Specification 912,399 (Group XXIV) where the carrier band brake is in parallel with a one-way detent.
