Title: Process for increasing the water solubility of lipophylic therapeutic substances
IPC: A61K47/00
Filed: 1954-03-17
Abstract: The water-solubility of lipophylic therapeutic substances is increased by mixing them with one of the following compounds:-ethyl urethane, antipyrene, ethylene- or other lower alkylene diamine, diethyl-amine or pyridine, and a non-ionic surface active agent having lipophylic and hydrophylic portions until a homogeneous material has been obtained.  The material may be dissolved in water, thimerosal (N.F.) water or physiological salt solution for injection or oral administration.  Examples of lipophylic substances are hormones and steroids, such as progesterone, testosterone propionate, diethyl stilbestrol, folliculin, estradiol monobenzoate, aleandrin, sulphones, salicylamide, estrogens, androgens, diaryl sulphones, and some antibiotics e.g. penicillin G procain.  Non-ionic surface-active agents mentioned are polyoxy-ethylene (20) sorbitan mono-oleate and the mixed polyoxyethylene ethers of mixed partial oleic esters of sorbitol anhydrides sold as Tween 80 and Polysorbat 80 (Registered Trade Marks).  The solutions may also contain polymers of partially methoxylated galacturonic acids.

Title: Improvements in change speed gearing
IPC: F16D11/10
Filed: 1925-03-25
Abstract: 250,383. A.G. Cars, Ltd., and Weller, S. B. March 25, 1925. Clutches; variable-speed gearing.-In changespeed gearing wherein one or more slidable splined gears such as 5, Fig. 4, are used, the female splines in the gear are used for clutching. Thus the coacting clutch dogs 8 may simply engage unmodified spline grooves 12, Fig. 5. Preferably the splined grooves 12 are deepened as shown at 13, the dog-engaging deepened groove being narrower than the spline groove. This groove 13 is preferably formed by broaching right through the gear as shown in Fig. 4, but it may extend only a short distance. The gear-box is thus shortened.

Abstract: 827,291. Developing electrostatic images. RADIO CORPORATION OF AMERICA. March 14, 1956 [March 23, 1955], No. 8029/56. Class 98(2) An electrostatic latent image is devel. oped with a mixture of developer powder and magnetic carrier particles applied under the influence of a magnetic field and a unidirectional electric field. As shown in Fig. 1, the latent image is developed on the photoconductive layer 41 by means of developer powder mixed with a magnetic carrier 23 which adheres to a magnet 21 to form a "brush", while a source of potential is connected between the magnet and a backing member 43. A positive or negative image may be obtained by reversing the potential by means of switch 33. In Fig. 2, the xerographic member is in the form of a paper web 51 having a photoconductive coating 53. The latter is given a uniform charge by means of a corona discharge 57, the sign of which charge may be reversed by switch 61. The charged web is exposed at 65 and developed by powder 24 applied by a magnetic brush consisting of a rotating magnetic core 20, connected to an opposite magnetic pole 45, and spaced discs 22 which hold the magnetic carrier 23. An electrical potential is applied between the earthed core 20 and a backing plate 44. The developed image is fixed by a heater 73.

Title: Improvements in weighing machines, having means for indicating the price to be paid
IPC: G01G19/41
Filed: 1925-03-26
Abstract: 240,077. Noorlander, W. March 26, 1925. Computing-apparatus; pendulum-weight apparatus.-In a weighing machine for indicating the cost of the goods, a longitudinally-movable bar actuated by the weight of the goods and determining the movement of the weight-indicating means, acts upon one or more levers the load points of which are adjustable along the levers and also along a second bar-like member actuated by the levers in the same direction as the firstmentioned bar and adapted to operate the means for indicating the amount of money to be paid. The scale pan 1, Fig. 2, is supported on two pendulum levers 10, 11, and its vibrations are damped by a dash pot 17. The pendulum lever 11 actuates the weight-indicating pointer 27 through a toothed sector 20, rack bar 24, and gear wheel 25 mounted on a shaft 26. The rear end of the shaft 26 carries a dial 29 for indicating the weight to the purchaser. The cost of the goods is indicated on a dial 149 actuated from the rack bar 24, Fig. 1, by means of slotted bars 31, 32 slidably pivoted on pins 33, 34, and by a vertically-guided rack bar 46 connected to the slotted bars 31, 32 by means of pins 44, 45 and horizontal slotted arms 60, 61. The extent of rotation of the dial 49, and consequently its cost indication, depends upon the positions of the pins 44, 45 and these are adjusted horizontally by means of slotted bars 35, 36 carried by racks 37, 38 operated by a finger knob 40 which simultaneously sets the price-per-unit-weight pointer 42 over the price scale 43. A price scale 43<a> is provided also for the purchaser. Taring devices. The pendulum 1 is normally clamped to a slotted disc 51 and is thereby connected to the indicating mechanism. In allowing for the tare the pendulum is released from the slotted disc by unscrewing a knob 53, Fig. 1, thus permitting the pointer 27 and dial 49 to be set to zero position by means of a knob 59. Upon again clamping the pendulum to the slotted disc the machine is ready for ordinary use, the tare being eliminated.

Convention date, April 14, 1931. [Classes 39 (i) and 40 (iii).] Scanning-apparatus for television comprises a rotating reflector or mirror 3, Fig. 4, cooperating with a wholly fixed picture composing or decomposing device such as a cylinder or drum 6 having a helically disposed series of apertures 5, the light passing through the latter falling upon a photo-electric cell or being received from a discharge lamp. The cells or lamps 7, 8 may, as shown in Fig. 3, be of semicircular shape so as to encircle the drum 6, or, by the employment of additional conical reflectors 22, 23, Fig. 10, and a second mirror 24 rotated synchronously with the mirror 3, an ordinary lamp or cell 26 may be used. When ordinary scanning, e.g. by a Nipkow disc, is effected, say, at the transmitter, rotation of the received image at the receiver by the mirror 3 is compensated by means of a triangular prism 9 or equivalent member rotated in the opposite direction to the mirror 3. In a modification the apertures are arranged spirally on a fixed disc on to or from which the light passes from or on to a conical reflector surrounding the mirror 3. The drum 6 may be built up of a number of superimposed steel rings 10, Fig. 5, having tapering slots 11 of the necessary predetermined size, and the slots of adjacent rings being adjusted by finger-pieces 12 to the desired angular distance apart. In another construction, the drum consists of an inner cylindrical member having a number of spaced longitudinal slots and an outer cylindrical member having a helical slot, the two cylinders in conjunction providing a series of helically arranged apertures.

In a method of moulding at least two articles, e.g. commutators, simultaneously, two moulds 17, 17A, each having at least one moulding cavity 27 therein and a sprue 16 or 16A extending through an end face 15 or 15A, are placed end to end in a structure 40 located between press platens so that when plastics moulding material is supplied to the space between the separated end faces and pressure is applied, the end faces are brought into abutment and material is forced into the cavities via the sprues, and a common moulding material discard space is formed between the end faces. Moulding material may be fed to the space between the end faces via an aperture in the wall of the supporting structure and arranged so that as the upper mould is lowered during the compression it cuts off the flow. In the modification of Fig. 5 the moulding material is initially placed in the mould, cavity 79 of each mould before they are placed in abutment within a structure 73; when pressure is applied by the press between the mould parts 72, mould cores 76 are brought into abutment with their end parts 74 to compress the material and force excess through the sprues 77 into a common discard space.
