Title: Vehicle engine cooling systems
IPC: G05D23/275
Filed: 1962-12-04
Abstract: 981,907. I.C. engine cooling systems. J. C. TAYLOR, and OTTER CONTROLS Ltd. Dec. 4, 1963 [Dec. 4, 1962], No. 45831/62. Heading FIB. [Also in Division H2] The operation of a radiator cooling fan is controlled by a thermally actuated switch 1, Fig. 2 mounted in a water-tight container 19 in the cooling circuit, the switch having associated therewith a heater 16 and the arrangement being such that operation of the switch with rising cooling liquid temperature renders the fan effective and the heater 16 ineffective whereas operation of the switch in the opposite sense with falling temperature renders the fan ineffective and the heater effective. The switch, which is preferably mounted in the header tank of the radiator, is operated by a bi-metal plate 1 constructed as described in Specifications 657,434 and 903,807, the switch contacts 12, 13 closing at a predetermined temperature and opening at a temperature about 10‹C. higher. The heater 16 heats the inside of the casing 19 when the contacts 12, 13, are open to avoid a big lag in operation of the switch when the cooling liquid temperature rises. In the circuit of Fig. 5 the switch contacts 12, 13 are in the circuit of an electric motor M driving the cooling fan and the heater 16 is connected across the contacts so that when the switch closes to energize the fan the heater is short-circuited and when the switch opens to cut off the fan the heater 16 is energized. Alternatively the heater 16 may be in parallel with the motor 17 and its circuit closed by the switch when the motor circuit is opened. The switch may alternatively control the operation of an electric or electromagnetic clutch in the drive of the fan.

Title: Recliner-Rocker Chair
Inventor: FLETCHER PETER STEWART
IPC: A47C1/0355
Filed: 1966-10-13
Abstract: 1,167,742. Seats. P. S. FLETCHER. 13 Oct., 1966 [21 Oct., 1965], No. 45859/66. Heading A4J. In a reclining and platform rocking chair, the chair can only be reclined on rocking it to its extreme forward position, in which nose 132 strikes base 10 and releases stub shaft 116, from slot 142 in locking link 130, thus enabling the leg rest lazy-tong linkage to extend, as the occupant exerts rearward pressure on the seat link 50 end back rest 42. The seat moves rearwardly about pivots 60 and 86 and bell crank 84, 94, swings to extend leg rest 46. The rearward motion of the seat 44 compresses spring 198 (Fig. 5) to overcome the action of inverted U-shaped coil spring 178 and turn hook link 166 about its pivot 172 to press roller 170 resiliently against edge guide 158d formed on hook bracket 158. In the semi-reclined position the rocking motion makes roller 170 track to and fro along guide 158d. The chair can only be moved into the fully reclined position by rocking it to the extreme forward position, in which roller 170 enters slot 158b and the consequential rotation of hook link 166 releases hook 176 from angle iron 184, which is rigid with carrier link 66. Carrier link 66 is accordingly released to turn about pivot 72 and bring the chair into the fully reclined position, in which the angle included between the seat and back rest is increased. Before the chair is moved into the fully reclined position, the roller 170 can be released from slot 158b by downward pressure exerted on the leg rest 46, to reduce the force exerted by spring 198 by slight forward displacement of the seat 44. Spring 178 may thus overcome the action of spring 198. Hook link 166 is locked to prevent release of roller 170 during the transition to the fully reclined position by parts 184, 186 engaging its upper end. In the fully reclined position hook 186 engages pin 168 to limit the rearward inclination of the chair. In another form (Figs. 11-13, not shown) hook link (166<SP>1</SP>) is manually actuated by means of a handle (220) and a toggle link (216). On returning the chair to the upright position part of the leg rest may operate the handle (220) to alter the position of the hook link (166<SP>1</SP>).

[Also in Division G3] In a system for controlling the tension of strip material in accordance with a control signal, an ultrasonic beam is transmitted towards and received after reflection from the strip and the control signal is derived from transmitted and received signals. In the embodiment of Fig. 3 for controlling the rate of conveyance of rubber tyre-tread strip 10 through cooling and drying apparatus, the echo time of an ultrasonic pulse reflected from a strip loop 18 formed between conveyers 16 and 20 is determined by unit 68 which provides a motor-speed control signal for adjusting the relative speeds of conveyers 16 and 20 to maintain the loop size constant. Details of cooling and drying apparatus employing several conveyers and associated ultrasonic speedcontrols are given (Figs. 1 and 2, not shown). In the second embodiment (Fig. 4) the rotational speed of a drum (92) on to which strip material is wound is slowed, as the winding diameter increases, in accordance with a control signal derived from an ultrasonic system in which the ultrasonic beam is reflected from the peripheral surface of the winding. In a modification the ultrasonic beam is continuous instead of pulsed. The control signal for the first or second embodiment is then derived by comparing the phases of the transmitted and received signals.
