As shown, a vacuum cleaner 20, Fig. 1, includes a canister tank 26 incorporating plastics bumpers 28, a tool-holding and handle assembly 32, the semi-cylindrical walls 64, 66 and two side walls 60, 62 Fig. 2, forming a hose-holding section 33, a flexible hose 72 with plastics coupling members 76, 86 and a detent button 87 on a metal end tube 84, a pair of extension tubes 50, 52, loosely mounted in storage channels 54, 56 respectively and each having an aperture (not shown) to co-operate with detent button 87, a locking control member 80 holding hose 74 in place, a rubber dome 90 having its inner face presented to the suction side of the cleaner and forming an efficiency indicator, a latch 92 for securing a front cap 22, a flex and plug 104 mounted for upward movement only, a front castor 110, a pair of plastics-tyred rear wheels 112, and an automatic brake for the rear wheels. As shown, the brake includes a left hand crank section 202, Fig. 2 inserted through a hole 206, and a similar right-hand section 204, the interior sections 210, 212 being joined by a sleeve 214. The outer end of left-hand section 202 forms an arm 216 covered by a plastics cap 220. In operation, when the vacuum cleaner is located on a stairway as shown in Fig. 3 the brake assembly is pivotted by gravity about the lower edges of holes 206, 208, to position 3, where further clockwise movement is prevented by contact of each cap 220 or 222 with its respective tyre. Only slight movement of the cleaner down the stairs causes the wheels to engage the caps frictionally until they jam the tyres at position C. On movement of the cleaner up the stairs when the brakes are initially in position C, the brakes quickly assume position B and further upward movement of the cleaner is permitted. Excessive application is prevented by a stop member 236. The brake assembly can be disengaged and held so by rotating it counter-clockwise (by one of the caps) until sleeve 214 resiliently deforms, and then rests behind, a resilient nipple 228.

Title: Carburettors
IPC: F02M1/10
Filed: 1967-05-03
Abstract: 1,124,555. Carburetters. FORD MOTOR CO. Ltd. May 3, 1967 [May 27, 1966], No.20423/67. Heading F1B. In a carburetter an induction passage has an air valve 62 and a throttle valve 64 located in it, the air valve being upstream of the throttle valve, the air valve is biased towards a closed position so that the pressure in a zone of the induction passage between the air valve and the throttle valve remains substantially constant during operation of an engine to which the carburetter is connected. Fuel can flow into the zone between the air valve and throttle valve through a fuel passage 74 and the flow of fuel through the fuel passage is controlled by a fuel valve 24. A linkage (not shown) interconnects the air valve and the fuel valve so that opening of the air valve opens the fuel valve and a thermosensitive device responsive to engine temperature is connected to the linkage so that at low engine temperatures the device opens the fuel valve and at higher engine temperatures opens the air valve. The linkage Fig. 1 (not shown) comprises an air valve arm 34 connected to rotate with the air valve and a fuel valve arm 22, 26 engaged by the air valve arm to be rotatable by the air valve arm to adjust the fuel valve. The air valve arm engages the fuel valve arm indirectly through a control member 29 which is adjustably mounted on the fuel valve arm. The thermosensitive device 48 cooperates with a lever so that rotation of the lever in one direction by the device rotates the air valve arm to cause the air valve to be opened and rotation of the lever in the opposite direction by the device rotates the fuel valve arm to cause the fuel valve to open. A member 82 responsive to manifold pressure contacts the fuel valve arm to increase the fuel flow when the manifold pressure is high. A fuel-air outlet may be positioned downstream of the throttle valve. This outlet may be supplied with a fuel air emulsion. It may be controlled by an adjustable needle valve.

Filed: 1937-10-20
Abstract: 504,243. Fluid-pressure servomotorcontrol systems. SPERRY GYROSCOPE CO., Inc. Oct. 20, 1937, No. 20478/38. Convention date, Oct. 23, 1936. Divided.application. [Class 135] In an automatic piloting device for aircraft a control surface 91 is actuated by a servomotor 90 to which pressure fluid is supplied through conduits 75, 76 from a control valve 92 which is actuated by gyroscopic apparatus enclosed within a casing 47 of the general type shown in Specification 416,813, [Group XXXIII]. A follow-up connection, (not shown) is taken back from the control surface to a follow-up pulley 5 of the gyroscopic device. An auxiliary control surface 70 mounted on the main control surface 91 is adapted to be actuated by an auxiliary servomotor 71 under the control of a relay valve 72<1> which is actuated by the pressures developed in the main servomotor 90. These pressures act through conduits 73, 74 on pistons carried by the valve member, Fig. 3, which is thereby moved to supply pressure fluid from a supply conduit 82<1> to one of the ends of the servomotor 71 to adjust the auxiliary control surface. The pressure supply conduit 82<1> is provided with a constriction comprising a needle valve 83 which retards the action of the servomotor 71 so that the auxiliary control surface 70 is only brought into action by disturbances of an appreciable duration and is not affected by momentary disturbances. The auxiliary control surface thus acts to relieve the main surface of any persistent disturbance and to adjust the trim of the craft. The auxiliary control surface 70 may also be adjusted manually by means of a hand-lever 97 which controls circuits of solenoids 98, 98<1> which act on the valve 72<1> to cause operation of the servomotor 71 as required. Interconnected byepass valves 87<1> and 95 are provided so that the servomotors 71 and 90 may be byepassed and the automatic control cut out. Specifications 414,592, [Group XXXIII], and 477,984 also arc referred to.
