Abstract: 1,101,268. Refrigerating. WESTINGHOUSE ELECTRIC CORPORATION. 27 April, 1966 [3 May, 1965], No. 18389/66. Heading F4H. In a refrigeration system having an accumulator 14 in the suction line, the refrigerant charge is sufficiently large that liquid refrigerant is always present in the accumulator and liquid refrigerant from the condenser 11 is passed through a coil 13 in heat exchange with the liquid in the accumulator. The evaporator 19 is normally overfed with refrigerant by expansion valve 17 which is responsive to the temperature and pressure of the liquid refrigerant upstream of coil 13, the arrangement being such that the valve tends to open upon increasing pressure and to close upon increasing temperature. A second expansion valve 50, in parallel with valve 17, opens when the evaporator outlet pressure becomes abnormally low. A high-pressure float valve or a valve controlled in response to the liquid level in accumulator 14 (Fig. 4, not shown), may be employed instead of valves 17 and 50. In one modification (Fig. 5, not shown), coil 13 is disposed in a subsidiary accumulator connected to receive liquid refrigerant from accumulator 14. The system may be operated as a heat pump having suitable reversing and check valves (Fig. 6, not shown), or have a liquid-fed coil disposed to re-heat air de-humidified by the evaporator (Fig. 8, not shown), A system having both these features is also described (Fig. 9, not shown).

Abstract: 361,336. Sewing-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. and BATES, A., Union Works, Belgrave Road, Leicester. June 17, 1930, Nos. 18445 and 29694. [Class 112.] Boot-sole stitching and lasting machines.-In a curved hook needle veldtschoen lasting and sewing machine of the kind described in Specifications 4058/12, 22110/13, 20047/14, 731/15, and 176,496, [all in Class 112, Sewing &c.], the upper-grippers are modified so that in fitting the upper to the last for sewing, no waste margin overhangs the sole. In sewing veldtschoen in which no rand or welt is incorporated, the grippers comprise jaws 3, 4. The lower jaw 3 is moved upwardly and the upper jaw 4 downwardly, by mechanism which allows of adjustment and detachment. A blade spring 12 enables the grip of the lower jaw to be resilient, while a coil spring 20 presses down the upper jaw. As a shaft 28 rotates, a lever 23 is first moved rearwardly to move the swing lever 34 about the shaft 35, so pushing the gripper bar 7 forwards to advance the jaws 3, 4 towards the work support. The front end of the lever 23 is then lowered about the pivot 24, causing the jaw carriers 5, 9 to be lowered about the pivot 6. A face 43 then engages the bottom of a recess in the gripper bar 7 and the lower jaw rises just above the edge of the work support to bring the margin of the upper between the jaws to that level. The lever 23 continues its downward movement to close the upper jaw on to the upper. Continued downward movement of the lever 23 compresses the spring 20, allowing for different thicknesses of work. As the shaft 28 continues to rotate, the lever 23 is moved forwardlv by the cam 27 to draw the grippers rearwardly to pull the upper, the strength of the pull being adjusted by the spring 32. Lugs 13, 14 part company when the grippers are closed. When they are reopened by the upward movement of the lever 23 which occurs as the eccentric 27 rotates, the lug 14 engages the lug 13 and lifts the rear ends of the gripper carriers 5, 9 against the action of the spring 12. When the machine is to be used for sewing veldtschoen in which a welt or rand is to be incorporated, the lower jaw is shortened or the carrier thrust back so that the jaw no longer protrudes beyond the upper jaw when closed.
