IPC: H01B17/02
Filed: 1929-08-01
Abstract: 337,748. Hermsdorf-Schomburg-Isolatoren Ges. Dec. 5, 1928, [Convention date]. Addition to 289,709. Insulators.-In order to increase the bearing surface of the spring ring on the insulator in pin insulators of the type described in the parent Specification in which, to maintain the pin in position in the pin cavity, a spring ring is fitted under the pin head, an intermediate ring is inserted between the pin head and the spring ring or the diameter of the spring is increased. In the construction of Figs. 1 and 2, an intermediate ring formed in segments 14 is inserted between the pin head 16a and the spring ring 12 in the insulator pin cavity 15. A split ring 17 holds the segments 14 in position until the filling metal is poured in. In a modified construction the intermediate ring is formed in one piece and comprises a cylindrical collar which is expanded by forcing it on to the pin head. The intermediate ring is held in position by a pin member and the filling metal poured in. The increase in bearing surface may be obtained without an intermediate ring by increasing the coil diameter of the spring ring which is formed in sections held in position in the pin cavity by a spiral ring. Specification 297,613 is referred to.

Abstract: 417,153. Cosmetic &c. receptacles; fastenings. ASSOCIATED APPLIANCES, Ltd., 7, St. James's Street, Pall Mall, London. Aug. 26, 1933, Nos. 23770/33 and 6042/34. [Classes 18 and 125 (i).] A mirror 1, Fig. 5, hinged to a receptacle 2 for a cosmetic pencil holder 3 is held folded down against the receptacle when the holder is housed therein by the engagement of a catch 4 on the holder with a hook 5 on the mirror. An arm, 14 limits the upward movement of the mirror and the catch 4 may be dispensec with if, as the holder is slid into the receptacle, its enc engages the arm and lowers the mir ror and holds it folded down. In a modification, the end of the holder acts upon the arm 14 through the intermediary of a rod sliding on the outside of the receptacle 2, and the mirror is fully lowered before the movement of the holder is completed so that the mirror is lowered and latched in one operation. The cosmetic pencil may be projected or retracted by a knob 15, these movements being effected automatically by a spring hook 16 as the holder is slid out of or into the receptacle. The device is held during use by a pivoted handle 8 which may also be of stirrup form. The mirror may constitute the inside face of the lid of a vanity case or perfume flask, the body part of which is provided underneath with a recess into which the receptacle 2 can be soldered, or hooked, clamped, &c. In a modification, the mirror is hinged to a ring member 1, Fig. 8, and the latter is hinged to the receptacle 2 or to the lower part 1<b> of a vanity, &c. case at a diametrically opposite point, and both hinges incorporate springs tending to raise the mirror and the ring. A cosmetic stick holder may be housed at each end of the receptacle 2 and the arrangement is such that withdrawal of one holder releases the mirror and withdrawal of the other releases the ring member, or, alternatively, the mirror is held closed by a finger catch. The member 1 may be divided by a partition 23 carrying a further mirror on its under surface. In another embodiment, the lid 1, Fig. 13, of a vanity case is held closed by a spring hook 10 projecting through an aperture in a receptacle 2 housing a cosmetic pencil 3, and withdrawal of the pencil from its receptacle allows the hook to spring back and so releases the lid. In a further embodiment, a vanity &c. case is divided by a horizontal partition to form two compartments each with its own hinged lid 1, Fig. 11, and the case houses two cosmetic pencils 3, the withdrawal of either releasing one of the lids. The lid or mirror of the various modifications may be urged to the open or raised position by a leaf spring or a coil spring in the hinge, and the receptacle housing the lipstick holder could be replaced by clips.

Title: Improvements in or relating to alkali metal sesquicarbonates and carbonates
IPC: C01D7/14
Filed: 1962-06-22
Abstract: An alkali metal carbonate is made by (a) mixing for up to 5 minutes an alkali metal carbonate, an alkali metal bicarbonate and water, in a sequence providing for formation of a hydrated carbonate, contacting the bicarbonate therewith with consequent formation of a product containing solid alkali metal sesquicarbonate, the equivalent proportion of bicarbonate to carbonate being in the range 5 : 1 to 1 : 1; (b) the product is then heated to decompose and dehydrate the mixture, leaving alkali metal carbonate, which has larger particles than those formed from the calcination of an alkali metal bicarbonate alone, and has bulk density of 25-56 lb./cu. ft.  The alkali metal may be Li, Na, K, Cs, or Rb, and the starting material may contain an ammonium salt of carbonic acid, or water; e.g. it may be "ammonia-soda crystals."  Alkali metal sesquicarbonate is made by process (a) above, modified by use of a bicarbonate : carbonate equivalent proportion 1 : 1.6 to 1 : 2, followed by (c) ageing the product at 20-100 DEG  C. without loss of H2O and CO2, and drying at a temperature below the sesquicarbonate decomposition temperature. If the bicarbonate : carbonate equivalent proportion is 1 : 2, substantially pure sesquicarbonate results. Specification 765,602 is referred to.

Title: Improvements in or relating to magnetic core circuits
IPC: G11C11/06
Filed: 1955-08-26
Abstract: 780,784. Magnetic storage devices. WESTERN ELECTRIC CO., Inc. Aug. 26, 1955 [Sept. 7, 1954], No. 24561/55. Drawings to Specification. Class 38 (2). [Also in Group XXXIX] In an arrangement in which magnetic cores with substantially rectangular hysteresis loops and input, output and resetting windings are selectively pulsed from one remanent state to the other, each core is provided with a neutralizing winding connected in series opposition with the output winding so that spurious induced voltages are inhibited when resetting pulses are applied to an unselected core. The input, neutralizing and resetting windings on each core are closely coupled, while the output winding is positioned with maximum spacing from the other windings. This spacing ensures that maximum neutralizing and minimum spurious voltages are obtained due to differences in coupling between adjacent and spaced windings when an unselected core is driven into saturation by a resetting pulse. For complete cancellation of the spurious voltage, the number of neutralizing turns is arranged to be K times the output turns, where K is the coefficient of coupling between the resetting and output windings when operating in the saturation region. When the core is effectively changed from one remanent state to the other by an input pulse, the coupling between all windings on the core is substantially the same and an effective output is induced in the series circuit of neutralizing and output windings.
