Title: Improvements in or relating to thermostatic valves
IPC: G05D23/13
Filed: 1938-02-02
Abstract: 510,537. Thermally-actuated valves. GLENN, M. Feb. 2, 1938, No. 3272. [Class 135] A thermostatic mixing-valve for obtaining water or other fluid at a required temperature from hot and cold supplies comprises a rotatable valve controlling the inlets to a casing having a coaxial outlet valve, the rotatable valve being controlled by a thermostat and by a hand control which also operates the outlet valve. The casing 25 is connected at 22 and 23 to the hot and cold supplies, and fitted with an oscillating sleeve valve 29 formed with ports 30, 31 for communication with supplies, the position of the valve being controlled by a thermostat and by a hand control 68, and the casing being provided with an outlet valve 50 and a spout 54. The valve 29 is formed with a conical baffle 39 causing the hot and cold fluids to mix, after which they pass through a perforated partition 42 in the valve 29. Below this partition is arranged a coiled thermostat 44 connected at its outer end to the sleeve valve 29, and at its inner end to the stem of the outlet valve 50. The hand control 68 is carried by a spindle 65, which can be swung about the axis of the casing so as to set the sleeve valve 29 according to the temperature desired, which is then automatically maintained by the thermostat. The hand control 68 and spindle 65 can also be rotated about the axis of the latter so as to open the outlet valve 50 more or less, by means of a rack-and-pinion connection 67. The poppet valve 50 may be replaced by a valve of the disc or washer type. A hot and cold water supply system may be provided with two master thermostatic valves as above described, one controlling a main hot-water supply and the other a main cold-water supply, each leading to outlet valves at different points in the supply system, these outlet valves having mixing-devices but no thermostats.

The tines fall within no more than a 180 arc around the periphery of the casing and may lie in the same plane or may be spaced about the periphery of the lead, Figs. 3-5 (not shown). To stiffen the lead a stylet can be inserted through the end of connecting pin 20 through the lumen of conductor 15 to the tip 19. The lead may alternatively be J-shaped. Suitable materials for the casing 17 and tines 22 are silicone rubber and polyurethane, platinum-indium being suitable for the tip 19. To facilitate positioning, the lead 10 or tines 22 may be made radiopaque by impregnation of carbon, barium, sulphate or tantalum. A second electrode may be positioned spaced from the tip to operate in a bipolar mode.

Filed: 1916-03-18
Abstract: 106,454. Goddard, J. W., Jerram, A. E., and British United Shoe Machinery Co. March 18, 1916. Presser-feet; presserbars; feed by presser.- The presser-foot and feed point are alternately raised from the work and each serves as a fulcrum for raising the other. The presserfoot is constructed so that when the presserbar is raised, the foot remains lightly in contact with the work and serves as a guide in channelled work. The presser-bar 105 carries a pivoted presser-foot 104 which, when the presserbar is lowered, is positively pressed on the work by the abutment of the pin 106, but when the presser-bar is raised, a spring-plunger 107 causes the pressure-foot to rock and presses it lightly on the work or into the channel. The feed-point 108 bar slides in the presser-bar and is rocked by the arm 122 of a bell-crank actuated by a cam track. The feed point enters the work vertically and leaves it in an inclined direction. The feed-point bar and the presser-bar are pivoted at their upper ends to a plate 111 which is urged downwardly by a spring-pressed pivoted bar 118. The plate 111 is pivoted also to a lever 113 on a cam-actuated bell-crank 114 by which it is rocked so as to raise the presser-bar and the feed-point bar alternately, the other bar serving as the fulcrum of the plate 111. The presser-foot and feed point are raised clear of the work by the treadle-operated lever 127. The presser-bar is locked by the arm 129 of a lever which is forced against it by a spring-pressed plunger 132. The lever is rocked to unlock the presser-bar by a camoperated tappet lever 130. The machine described and shown is of the character described in Specification 15756/12; the needle-bar-operating mechanism is of the kind indicated in Specification 24489/09. Reference is made also to the feed mechanism described in Specification 36/82.

Abstract: 905,352. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 4, 1959 [Feb. 7, 1958], No. 3948/59. Class 37. Electrode bodies to be alloyed to a semiconductor material during the manufacture of a semi-conductor device are held in position by associating with them ferro-magnetic materials, for example by enveloping, mixing, alloying with the electrode or by placing magnetic inserts in the assembly jig so that the electrodes may be urged magnetically into contact with the semi-conductor. As shown in Fig. 1, electrode bodies 6 which may be pellets of indium coated with iron are attracted towards the N-type germanium 3 to which they are to be fixed by magnets 5 which may be pointed so as to locate the magnetic inserts accurately. In Fig. 3, the electrode inserts 17 and a plug 18 of magnetic material are held by a magnetized insert 16 so that the jig can be converted to allow insertion of a non-magnetic electrode body in a hole in insert 16. In further arrangements (Figs. 5 and 6, not shown) permanently magnetized plugs attract each other or an electromagnetic field may force plugs of magnetic material together to hold the electrode inserts in contact with the electrode body.
