Title: Pushbutton structure
IPC: H03J5/12
Filed: 1962-12-11
Abstract: 985,593. Adjusting radio apparatus. MOTOROLA Inc. Dec. 11, 1962 [Dec. 21, 1961], No. 46659/62. Heading H3Q. A push-button tuning mechanism for a radio receiver comprises a sliding bar 14 having a push-button 10 secured to one end, a further bar or rod 20 detachably secured in sliding relation to said bar 14, there being a pivot pin 22 on said rod 20 upon which a cam 24 whose angular setting determines the receiver tuning when the push-button is depressed is removably mounted, a locking lever 30 having one end detachably secured to the rod 20 so as to hold the cam 24 on the pivot 22, and means forming part of the sliding bar 14, whereby when the bar 14 is moved in one direction with respect to the rod 20 by depression of the push-button 10, the other end of the locking lever 30 is moved so as to lock the cam 24 against rotational motion on its pivot 22, while when the bar 14 is moved in the opposite direction by withdrawal of the push-button, said other end of the locking lever 30 is released so as to permit rotation of the cam 24. As shown in Figs. 1 and 2, the rod 20 is coupled to the bar 14 by means of a downwardly-turned lug 18 thereon which engages within a longitudinal slot 16 in the bar 14. The lever 30 is held to the rod 20 by its end 32 passing through a slot in an upwardly-turned portion of the rod 20, thus preventing removal of the cam 24 from its pivot pin 22. In the position shown with the pushbutton depressed and the right-hand end of slot 16 engaging the lug 18, the left-hand end of lever 30 is engaged by a hook-shaped member 38 formed integrally with the rod 14, thus depressing this end of the lever towards rod 20 against the action of spring 25 and causing its right-hand end to bear on cam 24 to prevent rotation thereof. When the push-button is depressed the cam bears against parallel rods 52 which operate through lever 54 to tune the receiver as shown in Fig. 2. To effect adjustment of the cam 24, the push-button 10 is withdrawn so that the lug 18 engages the lefthand end of slot 16. The hook 38 then slides over the raised end of lever 30 to a position, Fig. 4 (not shown) wherein it no longer engages the lever which is consequently pushed upwards by the spring 25 so as to release the cam 24. The receiver may then be tuned manually and depression of the push-button will then lock the cam 24 in a position corresponding to the selected tuning setting. In an alternative arrangement, the slot 16 is omitted from the bar 14 and the rod 20 is shaped as shown in Fig. 11 so that the bar 14 slides through the slot 82 in the down-turned portion 80. Movement of the bar 14 is limited in one direction by the tongue 90 and in the other direction by shoulders on the bar 14 which engage the portion 80. Movement may also be limited, Fig. 7 (not shown), by a projection on the lever 30 which engages against the hook 28.

Title: Improvements in or relating to dry cleaning machines
IPC: D06F43/08
Filed: 1963-12-04
Abstract: 1,011,642. Dry cleaning apparatus. ENGELHARD HANOVIA Inc. Dec. 4, 1963 [Dec. 6, 1962; Aug. 12, 1963], No. 47985/63. Heading D1A. [Also in Division F4] A dry cleaning machine has a solvent storage tank 21 divided into a cold compartment 22 having refrigerating means 27, 28 and a vent 26 and a warm compartment 23, solvent being fed from compartment 23 to the cleaning drum 1 by a pipe 45 and valve 38, and being extracted from drum 1 by a pump 29 through pipe 47 when in liquid form and pipe 46 when in vapour form. When vapour is extracted it is mixed with cold liquid which comes from compartment 22 of tank 21 via pipe 48 and thus the vapour is condensed in the pump 29. Air and solvent are separated in a separator 30 and air is passed to the cold compartment 22 and solvent to the warm compartment 23. Within the drum 1 is a rotary perforate basket 2 on which is mounted a heater 3 controlled by a thermostat 4. Each time the thermostat reaches its maximum temperature and switches off the heater it brings into effect a mechanism which if the clothes are dry switches off the machine and if the clothes are wet switches the heater on again. This mechanism comprises a lever 15 operated by a solenoid 14 which brings a disc 16 into contact with a driving wheel 12 so that it is rotated thereby. If the clothes are dry the drum 1 cools down slowly and the disc is rotated until an arm 18 thereon operates a switch 20 to switch off the machine. If the clothes are wet the drum cools quickly and the thermostat de-energizes the solenoid 14 operating the lever 15 and hence stops the disc 16 before the switch 20 is operated.

The pressure relief valve comprises a seat 261, of elastomeric material such as Buna-N (Registered Trade Mark), and a closure member 272, of a plastics material such as polycarbonate, having a narrow annular valve surface 276. The closure member is loaded by a spring 282 and is guided by ribs (280) in its central aperture 278 which loosely centre it on a rivet-like fastener 212. The vacuum relief valve comprises the member 272 on which seats a bead 298 surrounding a central aperture in a flexible diaphragm 296 of an elastomeric material such as epichlorohydrin. The diaphragm is backed by a silicon-bronze spring washer 300 which provides a very small bias. The washer is made more flexible by the provision of openings 304 and radial slits 302. The cap comprises an outer protective shroud 202 and an inner cup-like member 206 which fits within the filler tube and is provided with conventional latching tangs 214, 216. The seal between the cap and the top of the filler tube is provided by a resilient generally flat sealing element 232 having inner and outer bead portions 234, 236. The inner bead is held sealingly between the end wall portions of the members 202 and 206. The lower part of the outer bead provides the sealing surface for the filler tube. A plurality of projections 238 engage the end wall of the cap to prevent overstressing. The seal is made of an elastomeric material such as Buna-N (Registered Trade Mark) and is reinforced by a silicon bronze insert 240. This insert, in addition to determining the sectional shape of the sealing element 232, provides additional protection against damage. Torsional damage is prevented by the inner bead 234 of the sealing element slides between the end walls of the . members 202, 206. In another embodiment of the diaphragm valve, Fig. 4 (not shown), a bead (444) surrounding a central aperture in a flexible diaphragm seats on an occluded seat member (432) having radially disposed supporting spokes (438). The diaphragm is backed by a spring washer (450), having apertures (456) and radial slits (452), to give a small bias to the valve member. Damage to the diaphragm from excessive back pressure is prevented by the diaphragm contacting the supporting spokes of the seat member.
