IPC: G05D23/24
Filed: 1963-07-11
Abstract: 1,035,367. Automatic temperature control. THETA CONTROLS Ltd. July 13,1964 [July 11, 1963], No.27571/63. Heading G3R. In an arrangement for controlling the supply of a heating medium the flow temperature is served by a detector A, formed by a thermistor 3 connected in series with a balancing resistor, comprising a resistor 1 and rheostat 4, which is connected across the primary of a transformer 10. The detector and transformer are fed as shown, at constant current from a transformer 5 through a high resistance 2. An imbalance between the currents through the two portions of the primary of the transform 10 due to a variation in the value of thermistor 3, caused by a flow temperature change, causes an error voltage across the secondary which is amplified by transistors 15, 16 and fed to transistors 34, 36 connected as a class B amplifier. The transistor 34,36 are connected, as shown, to relays 39, 40 so that the relay appropriate to the phase of the error voltage actuates contacts 47a, or 47b to energize a motor, not shown, to adjust the flow of heating medium. The motor also drives the slider of a feedback potentiometer 9, fed at constant current through a resistor 14, to vary the currents in the two portions of the primary of transformer 10 so as to tend to restore the secondary voltage to zero. The desired valve of the controlled temperature is adjusted by a potentiometer 7, fed at a constant current through a resistor 8. A further detector B, responsive to conditions outside the controlled space can be connected, as shown, to modify the effect of detector A. The responses of the detector B and of feedback potentiometer 9 are adjusted by potentiometers 6,13 respectively.

Title: Improvements in and relating to steering and like damping devices for automobiles
IPC: B62D7/22
Filed: 1929-09-12
Abstract: 337,128. Smith, F. Sept. 12, 1929. Vibration-dampers.-In a frictional damping device particularly applicable to the steering-gear and suspension of motor vehicles and cycles and in which the maximum resistance occurs in the central position while the effect diminishes for displacements in either direction, a number of friction surfaces are held in engagement by pressure and are so shaped that the areas in contact are greatest in the central position. In the construction shown in Figs. 1 and 2, the apparatus is clamped to the front axle C of a vehicle and the operating arm J is connected to the transverse track or steering rod. The arm J is integral with upper and lower friction discs H between which and the central disc A fixed to the axle are interposed embossed discs of frictional material, the whole being held together by a central pin M and adjustable spring washers P. K. The frictional discs are formed with radial projections D<1> which bear against corresonding radial projections on the outer discs H when the vehicle is steered straight ahead, but deflections of the steering wheels in either direction diminish the effective area of the frictional material in contact. In a modification applied directly to the swivelling axles of a motor vehicle, frictional and other discs approximately of semicircular form are employed as shown in Figs. 9 and 10. Similar apparatus may be applied to the steering-head of a motor cycle and to shockabsorbers controlling the action of vehicle springs.

In apparatus for controlling the movement of crates on a horizontal chain-link conveyer 4 so that they are delivered to an endless chain elevator having pairs of opposed cross-bars 5 in correct timed relationship therewith, a first crate 6b when positioned against a stop 11 operates a trip 10 opening a pneumatic valve 20 to cause cylinder 17 to lower a yoke pivoted at 15, the yoke having side plates 16 in which is located a stop bar 8 which when the yoke is lowered engages a projection 9 on a following crate 6a to stop the latter. The stop 11 is withdrawn downwardly in timed relationship with the movement of the cross-bars 5 of the elevator by a pneumatic cylinder 21 controlled by a valve 24, the latter being operated by a trip 13 which is connected by a cross-bar 5 of each pair. The arrangement is such that the cylinder 21 can only be actuated to withdraw the stop 11 if the valve 20 has previously been opened by a crate engaging the stop 11. A further trip 12 is provided which is operated by a crate entering the elevator to reset the stop 11 to receive the crate 6a which was released from the stop-bar 8 when crate 6b released the trip 10. The stop-bar 8 is adjustable in slots in the side plates 16 to compensate for crates of different sizes. If the apparatus is to be used with crates which do not have projections 9, a vertically movable support roller is arranged below the level of the conveyer 4 so that it can be projected upwards above the level of conveyer 4 simultaneously with lowering of the yoke, so that the leading edge of a crate is caused to abut the stop-bar 8, the roller being lowered as the yoke is raised. Stop mechanism.-A switch 30 is arranged to be operated by a trip 29 to stop the driving motor of the elevator if a crate should be projecting rearwardly as it is raised by the elevator.
