Title: Elevator control system
IPC: B66B1/20
Filed: 1963-12-11
Abstract: 1,025,812. Elevator control systems. HITACHI Ltd. Dec. 11, 1963 [Dec. 12, 1962], No. 49016/63. Heading B8L. An elevator control system is arranged to work in two modes according to the service demand. As described, two groups of three cars each selecting a first-starting car at the main floor; the service demand is estimated by counting the number of calls or car trips in the entire plant and determining whether the total exceeds a specified number; when the demand is light the first-start-holding-contactors 41, 42 are interlocked so that only one group (the group having a car scheduled to start next) responds to calls; with normal demand a relay 2 is energized to parallel the first-start-holding-contactors, and the groups respond alternately to calls (alternate response by interlocked contactors 61, 62).
Patent GB-490694-A (GB)
Abstract: 490,694. Anti-aircraft firing practice. CONTRAVES AKT.-GES. Feb. 23, 1937, No. 5468. Convention date, Jan. 14. Addition to 481,820. [Class 119] A method of measuring and registering errors in aim during firing exercises with blank or live ammunition against moving targets, such as an aircraft 1, comprises following the target by two theodolites 2, 3, transmitting the co-ordinates of the theodolites to a central apparatus 4, transmitting to said central apparatus the settings S, E of the gun 5 and T of the fuze setter, delaying the transmission of these settings S, E, T by a main retarder 6 to allow for the time of flight of the projectile, and further delaying the transmission of the setting T by an additional retarder 7 according to the " charge delay time " of the gun, that is, the time which elapses between the timing of the projectile fuze and the discharge of the projectile from the gun. The firing signal is transmitted by leads 16, 17 to the theodolites and serves to actuate the shutter mechanisms when photo-theodolites are used. The error in aim computed in the central apparatus 4 is indicated by an instrument 18. The present method may be used in conjunction with that described in Specification 481,820. The retarders may be as described in Specification. 485,930, [Group XXXVIII].

Title: Method and means for forming hollow articles out of a sheet of thermoplastic material
IPC: B29C51/10
Filed: 1965-11-25
Abstract: <PICT:1116097/C1/1> <PICT:1116097/C1/2> A hollow article is formed from thermoplastic sheet material, which may be of glass, by clamping the sheet in a frame comprising two pivoted halves, heating the sheet and then vacuum or blow forming the sheet on to a mould or former, the frame being pivoted to fold the sheet prior to or during the forming. In one embodiment, illustrated in Figs. 1-5, a sheet 1 is clamped in a split frame 2, heat softened, and then drawn by a male member 4. The member carries a V-shaped bead 6 against which the clamp is folded at a certain point in the drawing operation, the sheet then being vacuum drawn against the member, recesses 7 and 8 being formed.  The article may be released by disassembling the mould or by re-opening the clamping frame a certain amount (see Fig. 5, not shown).  In an alternative embodiment, see Figs. 6-13, the sheet is clamped in a lower split frame and mould halves M, M1 are carried by an upper split frame, the pivotal axes of the frames being vertically aligned.  The clamped sheet is first heated from both sides, after which the lower split frame is pivoted by upward movement of the axis relative to fixed rollers 43, the sheet being pre-inflated by hot air from 47.  After a predetermined movement of the lower split frame, the upper split frame is similarly pivoted by upward movement of the pivotal axis relative to rollers 17 so that the mould halves are pivoted on the sheet, the sheet being welded and cut along the line of contact of the mould halves.  The enclosed pre-inflated body is then sucked or blown into contact with the mould halves to form a completely closed article.

Title: Fluid-flow control systems
IPC: F22D5/26
Filed: 1963-12-20
Abstract: 1,66,827. Automatic fluid flow control. CONSOLIDATED ELECTRODYNAMICS CORPORATION. Dec.20, 1963 [March 1, 1963], No. 50324/63. Headings G3P and G3R. In a system for automatically maintaining a rate of fluid flow at a desired value, a regulating valve is adjusted in response to the pressure drop across it modified by the difference between a signal dependent on the desired value and a signal dependent on flow downstream of.the valve. In Fig. 1, the rate of flow of fluid, e. g. boiler feedwater, through a conduit 11 is controlled by a valve 10 operated by a servomotor 12 responsive to fluid pressure derived from across valve 10. An electric signal dependent on the rate of flow downstream of valve 10 is produced by a turbine type flow meter 25 and compared with a reference voltage from a potentiometer 28 so that any change in the ratio or the difference of the two signals results in an output from a controller 26 which is effective through an electric follow-up servo-system 30 to energize an electrically operated pilot valve 20 and thereby adjust valve 10 to correct the change. The rate of flow is thus maintained at a value related to the setting of potentiometer 28 which may, for example, be adjusted in accordance with the rate of steam supply from the boiler. In one modification controller 26 and servo-system 30 are pneumatic and, in another, a follow-up signal is derived from valve 10 instead of pilot valve 20. Followup signals from valve 10 may be produced by a potentiometer actuated from servomotor 12 through a spring and torsion bar.

Abstract: 1,121,388. Laminates. GENERAL ELECTRIC CO. 10 Nov., 1966 [27 Dec., 1965], No. 50457/66. Heading B5N. A process of stabilizing the frequency response of a metal-clad polyolefin laminated structure comprises cycling the structure from room temperature into a uniform upper temperature just below the incipient melting point of the polyolefin, to uniform room temperature, to a uniform temperature of 0F. and to uniform room temperature until the frequency response remains essentially constant. The upper temperature is preferably 125 F. or 150 F. and the metal is preferably copper. The laminate is formed by application of heat and pressure to an assembly comprising the polyolefin sandwiched between two layers of the metal and the temperature cycling is effected immediately after formation of the laminate. Cycling is continued for about six cycles Suitable polyolefin materials are polyethylene, blends and no -polymers of olefins, such as ethylene with butadiene, isobutylene, propylene, butenes and pentenes, blends or co-polymers of an olefin with acrylonitrile, vinyl acetate and various acrylates.

Abstract: 1293606 Automatic mixture control UPJOHN CO 17 Oct 1969 51217/69 Heading G3R True error per unit time is computed from sample error measured in sample time. As applied to a chemical blending apparatus described in Specification 1261961, the required number of amine units to 1000 resin units is set up on store 11. The actual flows of resin and amine units operate counters 20, 22, the attainment of either of the two numbers operating circuit 40 and the attainment of the second number restoring 40. While circuit 40 is operated the pulses on amine lead 16B step error counter 12. A clock 9 sets a standard time base (1/10 sec). It opens gate 26 to pass resin pulses from 16A to counter 32 until circuit 40 operates. The count in 32 is then complemented. Constant frequency pulses from 30 are fed simultaneously to counters 32 and 36 until 32 reaches capacity when the  count in error counter 12 is reduced by one and a new cycle of stepping counters 32, 36 by oscillator 30 is started by control 28. The process repeats until error counter 12 reduces to zero. Counter 32 divides by 9 and counter 36 by 10 with an output to stepper motor 6 controlling the speed of the amine pump. The forward or reverse direction of 6 is controlled by anticoincidence circuit 40. The different dividing ratios compensate for the shortness of the standard time base.

Turbine 4 receives exhaust gas through conduit 5 which has an outlet to atmosphere controlled by valve 17. Air from compressor 3 is fed to intake passage 11 and to pipe 10 through which it acts in chamber 15 on one side of a diaphragm 18 which is mechanically connected to valve 17. The pressure of air in pipe 10 is reduced by adjustable regulator valve 20 and through pipe 19 acts on the other side of diaphragm 18 in the same direction as spring 16 which biasses the valve closed. When the pressure in pipe 10 exceeds the combined effect of spring 16 and the pressure in pipe 19, valve 17 opens and reduces the volume of exhaust gas fed to the turbine 4 so that its speed decreases. In a modification, Fig. 2, (not shown) chamber 14 is open to atmosphere, and an adjustable valve similar to valve 20 is inserted in the line 10.
