Title: Electrical control circuit for vending machine
IPC: G07F5/18
Filed: 1967-11-14
Abstract: A vending machine comprises a plurality of article dispensing mechanisms 18, a common operating mechanism 26, a plurality of selection switches 55, 55a, 55b operable to energize an associated solenoid 46, 46a, 46b, 46c and pivot a coupling element 43 to connect a selected article dispensing mechanism with the operating mechanism, and a control circuit including a credit relay 72 energized when a coin is inserted in the machine, a vend relay 82 controlling a motor 34 driving the operating mechanism, and hold-on circuits for the credit relay, vend relay, and solenoids 46, 46a, 46b and 46c to ensure completion of an article dispensing cycle. The vending machine comprises compartments 14, each containing a stack of bottles supported on two rods 15, 15a. The rods are pivotally mounted and connected by links to an upright member 18. Reciprocation of the member 18 moves the rods 15, 15a apart to release a bottle. An operating member 26 extends across the compartments and carries solenoids 46, 46a, 46b and 46c, each co-operating with a pivotable member 43. Energization of a solenoid pivots the associated member 43 to couple movement of operating member 26 to the corresponding article dispensing member 18. The member 26 is supported between end plates 27 slidably mounted in a frame 21. The end plates 27 are connected by links 28 to cams 29 mounted on a shaft 31 oscillated by a motordriven cam 33. A cross-bar 22 supported by members 23 pivoted at 24 is moved towards and away from the stacks under the control of cam slots 41 to lower a dispensed bottle. Control circuit.-A coin actuates switch 67 to energize credit relay 72 and vend relay 82 momentarily, changing over hold-on contacts 72a and contacts 72b, 84. An article selection button 55, 55a, 55b is depressed to energize solenoid 46, 46a, 46b or 46c changing over a hold-on contact 62, 62a, 62b or 62c and pivoting a coupling member 43. Movement of a contact 62, 62a, 62b or 62c breaks the circuit of vend relay 82 whereby contact 84 closes on 85 to complete the circuit of drive motor 34. Selection button 55b alternately energizes solenoids 46b, 46c through switch 58 moved back and forth by associated members 18. " Empty " switches 92, 92a, 92c and 93, 93a, 93b are provided. Solenoid 76 is de-energized when the machine is completely empty (i.e. switches 93, 93a, 93b are all open) to release coin return member 73.

Title: Electric control circuit and hydraulic system for concrete pumping apparatus
IPC: F04B15/02
Filed: 1968-05-08
Abstract: A beater 41 in the feed hopper 18 of a concrete pump or pumps is driven by a liquidpressure motor MF5 under the control of a spool valve V10 monitoring flow from a supply pump (not shown). Movement of the valve V10 from a central shut-off position to which it is spring-urged passes fluid to drive the motor MF5 in one or other direction. The valve V10 is itself controlled by a solenoidactuated pilot spool valve V9 actuated by a manual switch. In the central position of the valve V10 the fluid recirculates to the supply pump. The hydraulic circuitry is part of the concrete pump control system (see Division F1).

Title: Process for preparing urea
IPC: C07C273/04
Filed: 1971-12-30
Abstract: A process for manufacturing urea by reacting ammonia and carbon dioxyde is described wherein the ammonium carbamate present in the synthesis effluent is decomposed under high pressure, the gas mixture resulting therefrom is at least partially condensed under a high pressure and the gas-liquid mixture produced in the condensation zone is introduced into the synthesis zone. The ammonia and carbon dioxyde still present in the synthesis solution after the high pressure decomposing of the ammonium carbamate are removed under a low pressure whereby an ammonium carbamate solution is produced, which is used as a washing agent for recovering ammonia and carbon dioxyde from an inerts containing gas mixture discharged from the synthesis zone. The wash solution thus obtained is introduced into the condensation zone, together with a quantity of urea containing solution from the synthesis zone, by means of a jet pump driven by fresh ammonia.

Title: Method for peeling fruits and vegetables
IPC: A23N7/02
Filed: 1974-03-08
Abstract: The present apparatus for skinning or peeling of produce comprises a rotatably mounted pressure vessel having a cover operable from within the vessel for sealing the vessel. The cover is pressure operated and permitted to fall open under the force of gravity upon pressure release. A pivoted latching pawl is provided in the pressure vessel for engaging the cover to hold it open. The pawl is also gravity operated to latch the cover in an open position. In the process for skinning or peeling produce, the pressure vessel is loaded with the produce, sealed and steam is introduced therein to rapidly increase the pressure and temperature within the vessel sufficiently so that a layer under the skin of the produce will come to a boil in response to pressure release. The pressure is maintained for a given period until the layer of the produce under its skin is sufficiently heated. Then the pressure is reduced to atmospheric pressure in either one or two steps, whereby said boiling occurs and the skin is removed thereby.

Patent ES-470943-A1 (ES)
Title: Highway crossing system with improved ring sustain feature
IPC: B61L29/28
Filed: 1978-06-20
Abstract: A highway crossing warning system includes a motion detector transmitter and receiver respectively coupled to the track rails adjacent the highway crossing for detecting motion of an approaching train. Wrap-around approach sections initiate operation of the highway crossing warning, but once motion is detected, the motion detector can serve to inhibit the highway crossing warning, after a predetermined delay, if motion indication ceases. To increase the effectiveness of the motion detection, the motion detector transmitter impresses a modulated carrier onto the track rails, wherein the modulation is phase locked to the carrier. The receiver, tuned to the carrier frequency, detects the modulation, and then determines from the level of demodulated signal whether or not approaching motion is detected. The transmitter employs solid state circuits switched between saturated and off conditions to prevent circuit component failures from masking approach motion. The ring sustain time period is arranged to provide a minimum constant warning time regardless of variations in train movement, so long as train velocity is maintained above a predetermined threshold within a predetermined distance from the crossing.
