Abstract: 419,025. Boxes for cosmetics. BOURJOIS, Ltd., Queen's Way, Croydon. March 16, 1934, No. 8377. Convention date, March 17, 1933. [Class 18.] A box comprises a body adapted to contain cosmetic or the like, an inner destructible cover for said cosmetic secured to the box body, an outer cover having its top spaced above the inner cover to accommodate an article or articles, supported upon the inner cover and retained in position by an article holder in the space between the two covers. A transparent destructible inner cover 17 fixed between the inner and intermediate plies 16, 15 of the three-ply wall protects the powder 18 and supports a bottle 22 for scent and a holder 24 for lipstick, these being located in shaped cut-outs 20, 21, formed in a cardboard disc 19, which is supported by the upper edge of the ply 15, and secured-e.g. by adhesive. The outer ply is higher and the inner ply shorter than the intermediate ply. The dependent wall 27 of the outer cover rests on a spacer ring 22 supported by a peripheral flange 28 of the bottom, and thus a space above the upper edge of the upright body wall, at least as great as the width of the spacer ring, is left for the bottle and holder, the former being held down by contact with the top disc 26. When the bottle and holder are removed the spacer ring 29, and the disc 19, may be torn away, when the box becomes an ordinary powder box. In a modification, the ring 29 is omitted, and the outer ply 14 is made of such weight that the top disc 26 always abuts on it, the lower edge of the dependent wall 27 abutting on the ledge 28.

Title: Process for the preparation of halogenated 3-keto-steroids
IPC: C07J75/00
Filed: 1959-03-12
Abstract: 4 - Halogenated or 2 - halogenated - 3 - keto - steroids are prepared by contacting a 3-hydroxy (or keto)-steroid unsubstituted in positions 2 and 4 which has the normal or allo stereo configuration at the 5-carbon atom with chloric or bromic acid. The normal series gives rise to the 4-halogenated compounds, and the allo series give rise to the 2-halogenated compounds.  Further halogenation forms the 2,4-dihalogenated compounds in each case. The molar ratio of steroid to halogenic acid is preferably in the range of 1:2,5 to 1:4.  The chloric and bromic acid may be liberated in the reaction mixture by means of an acid from salts of the acids, e.g. from alkali metal chlorates and bromates.  The starting compounds for the above process may contain various substituents outside ring A such as free or functionally converted hydroxyl and keto groups, halogen atoms, lower alkyl groups and double bonds, and may belong to the pregnane or androstane series.

Title: Semiconductive circuit arrangement
Inventor: HEEKS JOHN STUART
IPC: G11C11/34
Filed: 1968-02-22
Abstract: 1,212,933. Bulk negative conductivity device. STANDARD TELEPHONES & CABLES Ltd. 22 Feb., 1968, No. 8740/68. Heading H1K. [Also in Division H3] A body of material exhibiting an inter-subband electron transfer mechanism which gives rise to a bulk differential conductivity characteristic and containing deep traps having a much larger captive cross-section for minority carriers than for majority carriers is provided with spaced contacts through which an electric field is established in the body and one or more minority carrier injecting rectifying electrodes disposed between them. Although N-type germanium at low temperatures and N-type indium phosphide are suitable, the preferred material is N-type gallium arsenide, which normally contains traps attributable to lattice defects or oxygen atoms. A plurality of P-type electrodes are disposed between the terminal field electrodes together with a capacitive electrode for detecting the transit of domains through the body. In operation the body is preconditioned by injecting holes from one or more of the P-type electrodes to produce regions of enhanced conductivity by the differential trapping effect. A triggering pulse then initiates transit of a domain and the current through the body increases as the domain travels through the regions of increased conducitivity. The conductivity pattern in the body may be reset between successive domain transits, but if the decay time of the injected carriers is long enough the device-can be used as a short term memory. Erasure of the conductivity pattern may be effected by optical quenching which excites electrons from the valence band into the traps to cause recombination. To avoid extinction of domains on passing the injecting electrodes, these are open circuited but in an alternative mode of operation one remains connected so that the increased forward bias arising from arrival of a domain causes it to be extinguished, thus enabling the effective length of the body to be altered.

Filed: 1942-06-29
Abstract: 563,478. Tipping apparatus. MITCHELL, E. B. N. June 29, 1942, No. 8949. [Classes 78 (iv) and 104 (ii)] Discharging apparatus for railway wagons comprises a tippler 11 in a fixed position, one or more wagon rail tracks 53, 153 parallel to the tipping axis of the tippler, a transfer carriage 26 adapted to receive a wagon 27 on rails 51, 52 and running on transfer rails 45 transverse to the wagonrail tracks, and means for moving the transfer carriage on its rails so that wagons may be transferred sidewise from the wagon-rail track 53 or 153 to the tippler, tipped therein and returned to either of the tracks 53, 153. The transfer carriage 26 is hauled to-and-fro on the rails 45 by means of a motor 55 and cables 58, 62 passing round end pulleys 59 and connected at 60, 61 to a block 63 having horns 64, 65 between which a pin 68 on the transfer carriage normally depends to form a driving connection between the cables and the carriage. When the carriage has been hauled out to its full extent it rests on rails 25 on a support frame 23 carried by the tippler. As the tippler is raised it lifts the carriage and the support frame, and the pin 68 rises and leaves the block 63 behind ; when the wagon has been tipped the carriage descends with the tippler and the pin 68 enters between the horns 64, 65 again. The carriage may be driven by chain, rack, or other gear instead of by cables. The tippler may be operated substantially as described in Specification 544,561 and comprises a cradle 11 having a buffer bar 12 pivoted at 20 to side members 13 which carry another crossbar 15 and are pivoted at 16 to a fixed structure. The cradle 11 is connected by a link 22 to the support frame 23 which normally rests on fixed blocks 38, 39. When the cradle is rotated by means of a winch 35 and a cable 33 secured to the cradle at 34, the link 22 raises the support 23 clear of the blocks 38, 39 and the wagon tilts sidewise against buffers 70 on the bar 12 ; further rotation of the winch causes the side members 13 to swing about the pivots 16 so that the cross-bar 15 clamps down on top of the wagon.

Filed: 1939-03-22
Abstract: 513,821. Blasting-cartridges, ROLFES, Ltd., and ROLFES, F. H. March 22, 1939, No. 9046. [Class 9 (i)] A clip for holding detonators in blasting charges comprises means connected to the detonator casing and/or to the fuze or electric wires,' adapted to be passed through the cartridge so that part of the said means projects beyond the cartridge and can be bent against the adjacent surface thereof, in order to resist or prevent retraction 'of the detonator by a pull on the said fuze or electric wires. As shown in Fig. 1, the clip comprises two complementary parts 1, 2 of half-ring section which are held about the detonator 3 by a ring 4 and are provided at their lower ends with tapered prongs 5, 6 having weakened zones 7, 8. In use, the clip and detonator are thrust axially downwards through the cartridge 10 until the prongs 5, 6 project from the lower end thereof whereupon the prongs are bent outwardly about their weakened zones so as to occupy the positions shown in dotted lines. Fig. 2 shows a modification in which the detonator 3 is inserted obliquely through the cartridge 10, the clip comprising a hook member 12 formed integral with a depending member 13 having flexible lugs 14, 15 whereby it may be crimped to the detonator, with or without the use of a ring 4. According to a further modification, Fig. 3, the clip consists of a flexible strip 17 which is pointed at its lower end and is formed at the top ,with lugs 19 adapted to be crimped around the detonator 3. When the extemity 18 of the strip 17 projects beyond the side of the cartridge, it is bent upwards into the position shown so as to constitute a hook preventing retraction of the detonator. A modification of this construction is described, Fig. 4 (not shown), in which the strip lies along the lower side of the detonator and is initially given an S bend so that it extends below the end of the detonator and has its point brought substantially into alignment with the axis thereof. After insertion in the cartridge, the pointed end of the clip is bent upwards as before against the side of the cartridge. Fig. 5 shows a further modification in which the clip consists of a strip 23 of arcuate cross - section throughout its upper part, an S-shaped bend 24 being provided adjacent the end of the detonator. At this bend, the metal of the clip is'compressed together as shown at 25 whilst, towards the end of the clip, the metal is flattened to provide a straight tip 26 which can be easily bent up about the line A - A in order to form a hook which will grip the cartridge.
