Abstract: 1369954 Packages M DIAMANT 30 March 1973 [30 March 1972] 15739/73 Heading B8C A protective wrapper for solid articles of varying shape and size, the wrapper being made of heat-sealable material, sealingly welded, to tightly surround the article, is characterized in that a pulling member 16 is joined to the wrapper at at least two attachment points in a manner such that, when a pulling force is applied to the member 16 in a direction away from the packed member the wrapper is forceably opened by bringing the attachment points closer together. As shown in Figs. 1, 2 a wrapper 1 is formed of two transparent, thin, plastics foils 2, 3 which are welded together by a peripheral seal 4, 5, 6, 7 to enclose a pen 12, two pulling members 16, 16 being formed by two incisions 8, 9, which may initially consist of perforations, and which extend between attachment points 10, 11. When the members 16, 16 are pulled apart, Fig. 2, the upper end of the package is contracted axially so that the upper end 13 of the pen 12 penetrates a perforation 17 below the top weld 7 and protrudes, for easy withdrawal, from the wrapper. In a generally similar wrapping arrangement, Figs. 3, 4 (not shown), a circular object (14) is enclosed within a circular wrapper, the incisions (8, 9) being of arcuate form. In a further arrangement, for a clinical thermometer (29), Figs. 5, 6 (not shown), the incisions (25, 25) are formed in the foils (19, 20) externally of a U-shaped line seam (21), the two foils (19, 20) being longitudinally displaced to provide at one end, a tab (22) and a projection (24), and, at the other end, a tab (23). As shown in Fig. 7 a single pulling member consists of a strip 31 joined to the exterior of the sleeve at attachment points 32. Several pulling strips may be attached in a similar manner and a number of sleeves are joined together, in a row, by intermediate tearseams, or welds, (33), Fig. 8 (not shown). The pulling members may be in the form of side fins which project from the side edges of the sleeve. A series of wrappers joined to form a web may be stored in reel form. If a hermetically-sealed package is desired the perforation 17, Fig. 1, is covered by a peelable strip, not shown. -The incisions 25, 25 may extend along the entire length of the sleeve.

Patent GB-354874-A (GB)
Title: Improvements in or relating to electric switches with arc extinction by self-generated vapour pressure
IPC: H01H3/52
Filed: 1930-05-22
Abstract: 354,874. High-tension switches. SIEMENS-SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. May 22, 1930, No. 15842. Convention date, Aug. 20, 1929. [Class 38 (v).] In an expansion switch as described in Specification 354,890, the final withdrawal of the contact-member from the conducting liquid is delayed until sufficient vapour has been produced by the arc to expand and condense when the contact-member is finally withdrawn and so extinguish the are. This enables an expansion switch to break effectively circuits on less than full load. As shown, the contact pin 11 has a cut-away portion engaged by a pivoted latch 14 held down by a spring 17 so that it can be withdrawn far enough to draw an arc under the conducting liquid. When the resulting vapour pressure reaches a predetermined value, the piston 15 is pressed in against the action of the spring 16 and the latch is withdrawn so that the continued upward movement on the contact pin assisted by the vapour pressure is effective to withdraw it and produce the necessary expansion to ensure extinction of the arc. With full load or overload the pressure produced is high enough to overcome the action of the spring 17 and force the latch aside without delay.

Title: Improvements in or relating to timing devices for use with x-rays and other penetrating radiations
IPC: H05G1/44
Filed: 1952-06-26
Abstract: 706,671. Photo-electric control of X-ray dosage. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. June 26, 1952 [Aug. 16, 1951], No. 16088/52. Class 40 (3) X-ray dosage is controlled by an image intensifier the photo-electric current of which is used to control the radiation source and/or photographic apparatus. As shown closing of a manual switch 15 energizes relay 19 and 12. Relay 12 energizes the X-ray supply transformer 11 and sets in operation the automatic shutter of a camera 6. The X-rays, after passing through the object under examination are received on a zinc sulphide screen 3 which is separated by a thin sheet of glass from a photo-emissive screen of antimony. At the opposite end of the intensifier is an output screen which may be of zinc cadmium sulphide. The photo-electric current passes through a resistor 7 the drop across which controls the bias of a tube 22 the anode of which is supplied through resistors 17 and 21 and normally open contacts of relay 19. A resistor 25 and condenser 26 are parallel with resistor 21 so that the condenser charges at a rate dependent on the photo-electric current in the image intensifier. When the condenser potential achieves a predetermined value a gas discharge tube 16 which derives its supply voltage from the drop in resistor 17 fires and operates a relay 14. This relay de-energizes the transformer 11 and switches off the automatic shutter. The circuit is restored by opening switch 15 when relay 19 short circuits condenser 26 and cuts off the supply through resistor 17 to tube 22. In consequence the tube 16 is also cut off.

Title: The manufacture of iron oxide pigments
IPC: C01G49/08
Filed: 1933-06-08
Abstract: Ferrosoferric oxide is obtained by heating water-soluble ferrous salts such as the sulphate or chloride in the solid state with oxides, hydroxides, carbonates or bicarbonates of the alkali metals, alkaline earth metals, magnesium or zinc in an atmosphere of moderately oxidizing nature.  The alkaline earth compounds should only be employed in cases in which the acid radicle of the ferrous salt produces a water-soluble alkaline earth salt.  The mixture may be heated at 200--700 DEG  C.  The moderately oxidizing conditions may be attained by passing steam or oxygen diluted with an inert gas such as nitrogen or carbon dioxide over the mixture, which may be heated in a revolving or muffle furnace. Alternatively, the mixture may be heated in a sufficiently large air-filled space, closed to prevent admission of excess air.  The reaction mass is freed from salts by washing.  The black product may be converted to red iron oxide by calcination at 700 DEG  C.
