Patent GB-928392-A (GB)
Title: Improvements in or relating to actuating means for fluid-control valves
IPC: F16K31/10
Filed: 1959-07-23
Abstract: 928,392. Valves. H. TIEFENBACH. July 23, 1959 [July 25, 1958], No. 25401/59. Class 135. A magnetic actuating device for a valve controlling a pressure medium comprises a control valve 10 having control means 9 operable by a lever 7 which is actuated by a movable magnet 2 mounted in a housing 1, the magnet 2 being movable by a control magnet outside the housing. The magnet 2, which is pivoted in the housing, is urged to the inoperative position shown in full lines by the lever 7 under the action of a pressure fluid in the valve 10. When the control magnet is moved the magnet 2 is attracted to the chain-dotted position 2a thereby actuating the valve, the magnet 2 being maintained in this position by its magnetic engagement with an iron stop 13 until the control magnet, of opposite polarity, is moved back again. As shown in Fig. 2, the lever arrangement and valve 25 are mounted in a housing 47 within a housing 22 containing a pair of shuttle-lift valves 18, 19, the magnet 49 being actuated by an electromagnet 28 secured to a closure plate 29. In operation, the pressure medium is directed by the valve 25 to a cylinder 46 which, through a piston-rod 45 connected to a pivoted lever 40, actuates both valves 18, 19 so that pressurized fluid passes from a common inlet 15 to one of the outlet ports 16, 17 whilst the other outlet port is connected to exhaust.

Title: Improved means for cooling milk
IPC: A01J9/04
Filed: 1944-12-18
Abstract: 586,255. Refrigerators ; cooling milk. FRIGIDAIRE, Ltd., ABBOTT, F. A. S., and LANDER, A. V. Dec. 18, 1944, Nos. 25419/44 and 4843/45. [Class 29] A self-contained refrigerated milk cooler comprises a spray ring 16 adapted to encircle the neck of a milk churn 4, and a compartment 2 having cooling coils 8 for collecting the water after it has passed over the churn, the water first contacting with the coils nearest the suction side of the compressor 21. The churn 4 stands on a perforated plate 3 above an inclined tray 6 from which the water runs through an aperture 7 to the collecting compartment 2 containing the evaporator coils 8 separated by baffles 9 providing a sinuous path for the water to the sump 11 of a pump 12 driven by a motor 13. The pump feeds the cooled water to the movable spray ring through a valve 15. The compressor 21 of the refrigerating machine is driven by a motor 22 and the suction pipe 19 of the compressor is connected to the top coil of the evaporator which is brazed to the tray 6. There will thus be no tendency for ice to form on this top coil. A hinged flap 5 forms a splash guard as shown or a lid for the compartment 2. Alternatively this flap may be hinged to the outside edge of the compartment 2 and swung down to form a ramp for the churns. The motors can be replaced by a small internal combustion engine. The coils may be spaced from the top of the compartment 2 to allow an ice-free space for the flow of water, and may have fins projecting into this space. For hot climates an insulated hinged cover may be arranged to enclose the drum.

Title: Improved manufacture of translucent sheet material
IPC: D06M15/233
Filed: 1936-09-18
Abstract: In the production of translucent plates or sheets by impregnating a textile fabric with a solution of a polystyrol resin in an organic solvent, drying and hot pressing, adhesion to the metal pressing-plates is avoided by employing, instead of a low - boiling member of a homologous series a solvent of intermediate boiling point.  Thus, toluene or xylene is employed instead of benzene.

In a modification only a single bearing is used to support the drive shaft. In an alternative construction an axially extending coil is suspended from the inner edge of the annular disc and is enclosed by a cupshaped yoke member which co-operates with a similar yoke member on the other side of the disc,

As shown, the carrier is produced from a stock strip 100 which is fed from a bin 104 or from a roll (130), Fig. 7 (not shown), to a chain conveyer 106 having pins 108 which engage holes 86 along the formed edge 62 of the strip. Leaf spreader elements 116 spread the leaves of the strip apart as the latter moves towards a loading station 120, 124 where suitable mechanism deposits negatives 122 and prints 128 between the leaves at a location along the strip between successive score lines 102 which define each carrier length, which is then torn off at a score line 102. In another form, Fig. 5 (not shown), the holes 86 are replaced by slots (90). In the arrangement according to Figs. 6 and 7 (not shown), the score lines are omitted and the loaded carrier sections are sheared from the strip by a shear device (148), (150), the length of each section being defined by marks (129) which are sensed by a photo-cell device (142). In another arrangement, Fig. 13 (not shown), the front leaf (306) of the carrier is shorter than the adjacent leaf the top of which is used for labelling &c.
