Title: Improvements in or relating to Ventilation Controls
Inventor: HYDE COLIN ESME
IPC: G05D23/24
Filed: 1968-03-21
Abstract: 1,184,977. Automatic temperature control systems. HYDOR CO. Ltd. Dec.4, 1968 [March 21, 1968], No.13818/68. Heading G3R. A ventilation control system for a controlled zone has a temperature responsive switch energizing a heating element thermistor compensation remote from the zone, the thermistor providing a signal controlling the speed of ventilating fans in relation to the temperature of the heating element. The fans preferably run at a minimum speed and the thermistor regulates the speed above this minimum, the speed being reduced immediately when the temperature setting of the switch is reached. The minimum fan speed is set by an operator and upon increase of temperature above the set point the fans increase in speed at a fixed rate dependent on the thermal characteristics of the heating element and the thermistor. If the temperature is not reduced sufficiently during the fan increase period, the fans will remain at full speed until the temperature drops to the set temperature. The fans will then reduce immediately to the set minimum speed. The element does not supply any appreciable heat to the zone.

Title: Improvements in relay devices for vehicles
IPC: F16D51/66
Filed: 1923-05-28
Abstract: 199,014. Renaux, E. P. June 8, 1922, [Convention date]. Actuated or applied by running wheel or axle; blocks acting on drums; cone and disc.-Vehicle brakes are applied by the frictional drag of an additional friction member preferably applied to the drum of the main brakes and acting upon these brakes through cam mechanism. The lever 7, Fig. 8, of the cam 5 by which the shoes 1, 2 are applied to the drum 20 is engaged by a further shoe 9 adapted to be applied to the drum by a pair of cams 10, 11 actuated by the lever 12 and interconnected by toothed quadrants 13, 14. The frictional drag on the shoe 9 when pressed against the drum acts through the lever 7 to apply the shoes 1, 2 to the drum. The arrangement of the cams 10, 11 is such that the drag of the shoe 9 has no reaction upon them. Springs 63 attached to the lever 7 serve to withdraw the shoe 9 from the drum. As applied to the front wheel of a motor vehicle, the lever 12 is connected to a rod 58 passing through the steering pivot and connected to a bell-crank lever 60 pivoted on the axle. A similar arrangement is shown but with the shoe 9 disposed on the outside of the drum. Fig. 4 shows a disc 9<1> freely mounted upon the wheel hub and adapted to be pressed against the drum by cams 10<1> actuated by gearing 19 and lever 12. The disc has cam surfaces 9<a> engaging rollers 1<1>, 2<1> on the brake shoes 1, 2 whereby these shoes are applied to the drum by the frictional drag on the disc. Figs. 5, 6 shows a pair of shoes 9 pivoted at 18 upon an arm 15 freely mounted on the wheel hub and adapted to be applied to the drum 20 by a wedge member 16 which is forced between rollers 9<b> on the shoes by a cam 10 and lever 12. When the shoes 9 are turned about the axis of the drum by the frictional drag, rollers 9<c> on the shoes engage cam surfaces 1<a>, 2a on the main shoes 1, 2 and apply these shoes to the drum. The main brake shoes may engage the exterior of the drum.

Title: Improvements in or relating to advertising or like signs or devices
IPC: G09F13/14
Filed: 1928-05-14
Abstract: 301,279. Frenkel, G. May 14, 1928. Signs; supporting. - An advertising device adapted to be illuminated by day-light reflected to the sign-bearing wall, is characterized by the use of reflecting surfaces adjacent to the lightadmitting opening to reflect downwardly into the casing any reflected rays proceeding upwardly, thus preventing the escape of any light which has once entered the casing and finally passing it all out through the stencils at varying angles by repeated reflection. Fig. 7 shows a double-sided sign with two convex surfaces acting as the downward reflectors. The whole of the inner surfaces of the casing are of reflecting material except for the actual letters of the sign-bearing plates. Light entering through the open top is reflected repeatedly until it all eventually passes out through the letters. Fig. 6 shows a multi-sided conical hanging cage, suspended by a ring 1 and chains 2,. and having adertvisements on all faces and a curved downward reflector above the ring 1. Each stencil receives light by reflection from all' the other faces of the cage. The apparatus shown in Fig. 7 may be moulded or blown in one piece as a glass tube, with a transparent light-admitting top, or may be made of separate panels. Opaque end frames 6 carrying flanges 5 and hooks 3 are used to assemble and suspend the appliance. The reflecting walls may also be concave, convex, undulating in one or more directions, or may be formed of a succession of narrow strips. Both the sign-bearing and reflecting walls may be of corrugated, ribbed, ornamental, or reinforced glass, and the letters &c. may be formed of ground or frosted glass or by sand-blasting or they may be. carried bv a movable screen which can be unwound from rollers at the end of the apparatus. The sign-bearing plate may be thinner or thicker in the letter-occupying area than the remainder of the plate. Stencils on opposed surfaces may be in staggered relation to increase the reflection from one plate through the other. The box may be made of celluloid, cellulose, gelatine or mica.
