Title: Servo-control for fluid pressure braking apparatus of motor vehicles with trailers
IPC: B60T15/46
Filed: 1963-09-12
Abstract: 1,007,745. Fluid-pressure brakes. FABBRICA ITALIANA MAGNETI MARELLI S.p.A. Sept. 12, 1963 [Sept. 15, 1962; Feb. 4, 1963], No. 35992/63. Heading F2F. A servo-control for the brakes of vehicles constituted by a tractor and at least one trailer is actuated by a control rod 10 by the brake pedal to cause piston 16 to move downwardly against the action of spring 32 until the bored push-rod 48 contacts a valve 44. This cuts-off the communication of the trailer brakes connected at 74, to atmosphere via chamber B, the bored rod 48 and chamber C which is connected to atmosphere. Further downward movement of the rod 10 causes the valve 44 to move away from its seat 42 to allow fluid pressure from a compressed-air source connected at 66 to flow via passages 64, 65 and chambers D and B to the trailer brakes to actuate the same. When the fluid pressure in chamber B reaches a predetermined value so that it can overcome the action of a pre-loaded spring 36 the piston 26 moves downwardly and acts via member 50 and push-rod 62 on the member K which may be a distributer valve or master cylinder to actuate the tractor brakes. In emergency braking when compressed air is not available the piston 16 engages with its slotted rim 24 the .piston 26 to move the latter so as to actuate the tractor brakes. In another embodiment the valve seat is provided in an extension of piston 16, the piston 26 being provided with a hollow push-rod and the compressed-air being communicated to the trailer brakes via a hollow push-rod 10. In a further embodiment the compressed-air source is connected to a port in the cylinder 18 and communicates with chamber B via radial and axial bores in the piston 16 in which the valve seat is provided. The piston 16 is connected directly to the push-rod 10, the spring 22 being dispensed with.

Title: Apparatus for controlling the thermal charging of an electric storage heater
IPC: G05D23/19
Filed: 1976-09-03
Abstract: 1503292 Control systems for electric storage Heaters DANFOSS AS 3 Sept 1976 [3 Sept 1975] 36622/76 Heading H2H An electric storage heater comprises a control system whereby the electrical energy for the heater is controlled according to the comparison between a maximum thermally charged condition of the heater in a given period and the instantaneous thermally charged condition in the succeeding period, the comparison being modified according to a thermal parameter related to the discharge of heat from the heater. The heater element 3 of a storage heater 1 is supplied with energy from an A.C. source 5 by way of an "OFF-PEAK" controlled switch 8, a relay operated changeover switch 9 and a thermal switch 10 which opens when the core 2 of the heater 1 assumes a predetermined upper temperature. Heat is dissipated from the storage heater by radiation and convection and by means of a fan 4 when a room thermostat 12 closes a switch 11. The core 2 of the heater 1 includes an expansible rod 14 which carries a first slider 16 of a potentiometer 17 and a second slider 18 fixed to a carrier 19 which is secured to the rod 14 by means of two springs 21, the carrier 19 being associated with an electromagnetic clutch 23, which clutch is connected to the lower contact of the switch 9 so as to be momentarily energized when the switch 9 returns to the lower contact at the end of a thermal charging period. Energization of the clutch 23 causes the carrier 19 to move to a central position in the recess 22 in the rod 14 thereby storing the maximum thermal charged condition of the heater 1 at the end of a charging period, the potential at the slider 18 being fed to the input 28 of a comparison device 26. During a subsequent period when the heater 1 is discharging heat the slider 16 fixed to the rod 14 will move upwards to provide a signal to the input 27 of the device 26. When next the switch 8 closes, the relay 25 will be energized by the device 26 to move the switch 9 to its upper contact so as to recharge the heater 1. The relay 25 will be de-energized to terminate the charging process when the two signals 27, 28 to the comparison device 26 have a predetermined relationship, the signal 27 having been modified by the charge on a capacitor C2; received whilst the thermostat 11 is closed; which charge is dependent on resistors R6, R7, the resistor R6 being responsive to the temperature of the core 2 and the resistor R7 responsive to outdoor temperature. When the relay 25 de-energizes the switch 9 moves to its lower contact again to energize the clutch 23 whereupon the carrier 19 moves to take up a position of a new maximum thermally charged condition of the heater 1.
