Abstract: 855,056. Coin-freed vending apparatus. LUCKENWALDER METALLWARENFABRIK VEB. Aug. 19, 1959, No. 28394/59. Class 27 A coin-registering mechanism for a vending machine having several coin insertion points comprises a steppable switch disc 9 with spaced levers 4 which can be pivoted into different planes according to the coin values to engage contacts 5, 6 or 7 spaced in the different planes at points round the disc periphery according to the coin values, so that the opening of the contact 5, 6 or 7 by the pivoted lever 4 first engaging it will arrest the disc at that point. Inserted coins 18 bridge contacts 21 and connect current to a self-holding relay 23 and a stepping magnet 12 and, in the case of higher-value coins, to one of two magnets for adjusting the position of a cam surface 8 for setting the levers 4 into the plane appropriate to the coin, the levers being held in adjusted position by spring clips. The relay tilts the pivoted member 20 for one contact 21 so that the coin is released and a stop 19 is titlted under a succeeding coin and the magnet 12 stops the disc 9 until, corresponding to the setting of the levers 4 by the cam, the first lever opens a contact 5, 6 or 7 and interrupts the stepping circuit. The disc 9 is geared to a counting wheel 11 having a pin 17 or pins insertable from either side in spaced holes in the wheel at points corresponding to the price of the goods and the pins open contacts 13 when the full price of the goods has been set up. The respective contacts 13 are rocked into operative position by selective push button operation and the wheel may be marked with progressive coin values so that the amount inserted can be ascertained through a window. During delivery of the goods, a contact is closed to energize a magnet 15 and the gearing to the wheel is disconnected, so that a spring can return it to initial position and, on completion of delivery, the magnet 15 is de-energized and the gearing is connected again.

Filed: 1950-11-27
Abstract: 680,079. Ironing-presses. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 27, 1950. [Dec. 2, 1949]. No. 28967/50. Class 138 (ii). An ironing-machine comprises a parallel linkage 14, 15, 16, a substantially U-shaped arm 8 carrying a shoe 6 and pivotally attached (at 17) to a movable element of the linkage, means 30 for driving the linkage in one direction relative to a fixed buck 5, fulcrum means 19 engaging the arm 8 at a point spaced from the pivot 17 for rotating the arm 8 upon movement of the linkage, and stop means 22 on the linkage which engages the shoe arm and prevents further rotation thereof when the shoe reaches a position Fig. 3 (not shown), in which it is parallel to, and spaced from, the buck, the fulcrum means 19 being arranged to yield upon further movement of the linkage so that the arm and shoe are moved normal to the plane of the buck and into pressing relation, Fig. 4 (not shown). The driving means 30 comprises an hydraulic motor (Fig. 5), the piston 33a of which is pivotally connected with the frame at 46. The cylinder 30a of the motor is connected to the parallel linkage at 32. Respective tension springs 24 are connected between the frame at 46 and the pivots 17 of the links 14. A pair of links 18 are pivoted to respective sides of the arm 8 at 19 and each have a pin-and-slot lost-motion connection with the frame at 21. A spring 26 is connected between each link 18 and an extension 23 of the respective link 16. The piston rod 33 is hollow and contains an electric motor 36 which is connected by a shaft 37 with an impeller 42 mounted in a chamber 39 within the piston 33a. On switching on the motor, liquid above the piston is pumped through piston ports 48 by the impeller causing the cylinder to be forced down relatively to the piston. The links 16 move with the cylinder but the fulcrum points 19 of the arm 8 tend to remain owing to the tension of the springs 19. Thus the arm 8 swings in a clockwise direction until the shoe 6 is directly above, and parallel with, the buck 5, Fig. , 3 (not shown). Further rotation of the arm 8 is prevented by a stop 22 on the extension 23, and on further downward movement of the cylinder 30a and links 16, the stop 22 draws the arm 8 and shoe 6 downwardly in a direction normal to the buck. This movement is permitted by the slots 21 in the links 18. When the motor 36 is switched off, the springs 24 and 26 return the parts to the position of Fig. 1. The shoe 6 may be electrically heated.

Abstract: 648,868. Covers for resisting fluid pressure. COMBUSTION ENGINEERING - SUPER-HEATER, Inc. Oct. 30, 1947, No. 28976. Convention date, Nov. 8, 1946. [Class 123(i)] [Also in Group XVII] A closure for an opening of a container subjected to internal pressure comprises a gasket 18 which is compressed against a pressure-head 16 by inward screwing of a ring 17 and thereby radially expanded into sealing contact with the inner surface of the container. Inward movement of the head 16 into the opening is limited by a constriction 15. An internally-threaded open-topped closure cap 19 is hinged to the container so as to align axially with the opening when closed thereagainst, and to be swingable outwardly away from the opening. The head 16, ring 17, and gasket 18, form an assemblage which is maintained in position by a stud bolt 27 affixed to the head 16 and projecting through a hole 32 on a plate 31 which is welded to the ring 17 and has a hand bar 37 by which the ring may be rotated to enable the assemblage to be screwed out of the opening and into the cap 19 and out of the cap 19 into the opening. Adjusting screws 41 on the cap enable it to be spaced from the container so as to cause corresponding threads 38, 13, in the cap and on the opening interior to be continuous. A lug 42 welded to the container co-operates with a lug 43 on the cap, Fig. 1 (not shown), to guide the cap into alignment in the closed position where it is held by a spring- loaded latch 44.

Abstract: 1320993 Intruder alarms SYSTRON-DONNER CORP 21 June 1971 [26 June 1970] 28986/71 Heading G4N [Also in Divisions H3 and H4]  In an intrusion alarm system in which a Doppler frequency is derived from radiated and received signals due to movement of an intruder, an appropriate spectrum of the Doppler frequency is selected by means of a bandpass filter 17 the output of which is fed to a pair of voltage doubling rectifiers 63, 64 having the outputs connected in opposition and having different charging times so as to have differing frequency characteristics. As described, a supersonic frequency of 19À2 kHz is radiated into the space to be protected, received signals being picked up by a transducer and after amplification in a balanced differential operational amplifier (Fig. 2, not shown) are fed to a bandpass filter 17 comprising an operational amplifier 46 having feedback via a twin-T network so as to pass a frequency band of 40Hz to a further operational amplifier 59. In the two diode pump voltage doublers 63, 64, capacitor 77 is ten times that of 76 whilst resistor 67 has one half the resistance of 72. Movement of an intruder tends to produce Doppler frequencies at the upper part of the band passed by filter 17 whereas unwanted frequencies such as air turbulence provide lower frequencies. The voltage doubler 67 produces an output greater than that of 64 for frequencies at the upper part of the band i.e. due to movement of an intruder so that a net positive output is available at the slider of potentiometer 81 which is integrated at 19. If the signals have sufficient duration, the output of the integrator is sufficient to turn on diode 93 and transistor 96 which turns off transistor 98, releasing relay 99 and operating an alarm. Automatic fault indicators.-Failure of the output from the transmitting oscillator causes transistor 97 to turn off, releasing relay 99 and operating the alarm.
