Title: Improvements relating to temperature control for a compartmental vehicle
Inventor: BENNETT ALBERT EDWIN
IPC: B60L1/02
Filed: 1957-04-15
Abstract: 827,774. Automatic temperature-control systems. STONE & CO. (DEPTFORD) Ltd., J. April 9, 1958 [April 15, 1957], No. 12235/57. Class 38 (4). In a heating system for a vehicle which is divided into separate compartments and in which the compartments are supplied with air from an automatically-controlled common airconditioning or heating equipment, auxiliary electric heaters are provided in each compartment and the thermostat of the common equipment is automatically reset if they are switched on. In one embodiment, for an A.C. supply, the current supplied to the auxiliary heater 1 is measured by a current transformer 7 which opposes a constant-voltage supply 8 to a bias heater 5 on the thermostat 4 of the common (undisclosed) heating system. Thus, if one or more of the auxiliary heaters 1 are switched on, the current through the bias heater 5 is reduced, thereby effectively raising the setting of the thermostat 4 to offset the fact that warm air from the auxiliary heaters 1 will flow past the thermostat 4 and would otherwise cause it to falsely reduce the common heating. In a modification, Fig. 2 (not shown), for a D.C. system, the bias heater is energized via an electromagnetic interrupter which includes a winding responsive to the current supplied to the auxiliary heaters. In a further modification, Fig. 3 (not shown), the bias heater 1 is connected in parallel with the bias heater on an auxiliary cycling thermostat which is additionally subjected to bias in accordance with the current supplied to the auxiliary heaters. The following optional extras are discussed: (1) a thermostat to cut-off the compartment heating if the vehicle temperature exceeds the controlled range; (2) a contactor to open when all, or a predetermined portion of the compartment heaters are switched on; (3) provision for raising the effective setting of the main thermostat to raise the temperature of the whole vehicle when the compartment heaters have been automatically open-circuited; (4) additional thermostats controlling the compartment heaters may be provided; (5) the supply for the compartment heaters may be arranged to be taken from the generator only of the vehicle (to save the battery).

Title: Arrangement for transferring packets of goods from the one to the other branch of a syphon-shaped goods shaft in coinfreed automatic vending machines
IPC: G07F11/14
Filed: 1927-05-10
Abstract: 282,586. Wistoft, S. May 10, 1927. Delivery of articles stored in piles; storage.- Relates to a goods vending machine having a storage magazine formed of two branches 1, 2 the goods being raised in the branch 1 and passing by gravity down the branch 2 from which they are delivered one at a time by a member unlocked by the insertion of a coin. According to the invention a mechanism for transferring the top packet from the branch 1 to the branch 2 comprises a pair of arms 29, 30 carried by a spindle 27 and having pivoted spring-controlled beaks. 34 for engaging the top packet, and a stop lever 7 pivoted at 6 and having a step 12 for engaging the uppermost but one packet so that the pile is prevented from rising and increasing the frictional resistance to the movement of the top packet. The spindle 27 has an arm 28 connected to the delivery member of the machine so that the arms 29, 30 are rocked by opening and closing this member. The lever 7 is normally held by a spring 13 against the end of a lever 14 which is pivoted at 15 and held by a spring 16 against a stop 17. A latch 19 which is pivoted ant 18 to and is held by gravity against a stop 22 on the lever 14, has a projection 23 flat on the top 24 and curved underneath at 25. During the forward movement of the arms 29, 30 to transfer the top packet to the branch 2, a pin 32 on an arm 31 integral with the arms 29, 30 moves past the projection 23 without affecting the lever 14. During the return movement, the pin 32 engages the flat face 25 and moves the lever 14 which, by acting on a curved portion 8 of the stop lever 7, moves this lever out of engagement with the pile. The pile rises until the top packet. meets the beaks 34 and, when the pin 32, escapes from the projection 23, the lever 7 returns to position to engage the second packet. The pressure of the pile turns the beaks 34 about their pivots so that the. arms 29, 30 can return to normal position, when the beaks are again brought into alignment with the arms. A second step 11 is provided on the lever 7 to engage the top packet of the pile if the step 12 for any reason has not engaged the second packet. The top of the branch 1 is inclined so that the upper packets are in the upward movement of the pile shifted slightly towards the branch 2.
