Patent GB-1589460-A (GB)
Title: Coin testing device
IPC: G07D5/04
Filed: 1978-05-30
Abstract: In order to separate out coins which are too heavy or too light, the device has a double balance (1, 11). A pivoting arm (3) forms an inclined rail (5) which serves as a running surface for the coins (M) and which has two portions (6, 7) of differing widths. A wall (8), which limits the path of the coins laterally, is arranged in such a way that the wider portion (6) always projects through it, but the narrower portion (7) projects through it only in the middle coin-accepting position of the pivoting arm (3). Coins which are too light cannot move the pivoting arm out of its position of rest, roll only as far as the end of the wider portion (6) of the rail (5) and there fall into the coin-ejecting channel (21). Coins having the desired weight press the pivoting arm into its middle coin-accepting position and roll on the rail (5) as far as its end. Coins which are too heavy press the pivoting arm (3) beyond the coin-accepting position and consequently follow the same path as the coins which are too light. As a result, two weighings are possible in one operation, and all the separated-out coins pass into the same coin-ejecting channel. <IMAGE>

Title: Halogenation and oxidation of steroids
IPC: A01K27/00
Filed: 1952-10-01
Abstract: 4-Halo-3-keto steroids, particularly 4-halo-21-acyloxy - 17a  - hydroxypregnane - 3 : 11 : 20 - triones, are prepared by contacting a 3-hydroxy steroid, particularly a 21-acyloxy-3 : 17a -di-hydroxypregnane-11 : 20-dione, with a hypohalous acid, preferably in an inert organic solvent.  The 21-acyloxy radical preferably contains from one to eight carbon atoms inclusive, and the starting materials may be further substituted by halo, alkoxy or alkyl groups. The preferred solvent is tertiary butyl alcohol, incorporating between traces to eighteen per cent of water.  In examples: (1) 21-acetoxy-3a  : 17a  - dihydroxy - pregnane - 11 : 20 - dione in aqueous tertiary butyl alcohol is treated with hypobromous acid to yield 4-bromo-21-acetoxy-17a -hydroxypregnane-3 : 11 : 20-trione. (2) As in (1) using hypochlorous acid to produce the corresponding 4-chloro-compound.  Numerous other 21-esters are listed.  (3) The 4-bromotrione of (1) and the chloro analogue are likewise obtained from 21 - acetoxy - 3b  : 17a -dihydroxy pregnane - 11 : 20 - dione. Other examples describe the preparation of 4-chloro-17a  - hydroxy pregnane - 3 : 11 : 20 - trione; 4 - chloro - pregnane - 3 : 20 - dione; 4 - chloro - 17a  - hydroxy - 21 - bromopregnane - 3 : 11 : 20 - trione; 4 - chloro - coprostanone; 4 - chloropregnane - 3 : 11 : 20 - trione; 4 - bromo - pregnane - 3 : 11 : 20 - trione; 4 - chloro - 11a  - hydroxy - pregnane - 3 : 20 - dione; 4 - chloro - 3 - keto - 17 - isoetiocholanic acid and its 4-bromo-analogue.  21 - Acetoxy - 3b  : 17a  - dihydroxy - pregnane - 11 : 20 - dione is prepared from pregnane - 3 : 11 : 20-trione by Raney nickel reduction, enol acylation, epoxidation of 17(20) double bond, hydrolysis, bromination in the 21-position and final treatment with potassium acetate.  21 - Acetoxy - 3a  : 17a  - dihydroxy - pregnane - 11 : 20-dione is prepared from 3a  : 17a -dihydroxy-pregnane-11 : 20-dione by bromination in the 21-position and treatment with potassium acetate.

Title: Improvements in machines for applying adhesive medium to envelopes, wrappers and the like
IPC: B31B19/00
Filed: 1919-10-09
Abstract: 155,928. Brooks, H. C., and Warbey, H. F. Oct. 9, 1919. Coating-machines.-In machines for applying adhesive to envelopes, wrappers, &c., the pile f of blanks is pressed up to a gumming-pad 2, from which the top blanks are successively drawn. One end of the top blank is raised from the pile by rotating suction nozzles 11, and is then pressed against travelling bands 16 by fingers 38 carried by rotating discs 33, so that these bands withdraw the blank from the gummer and deliver it to delivery bands 30. The pile f is placed on a table 50, which may be composed of parallel strips, as shown in Fig. 10, which can be slid relatively to each other to conform to the shape of the blanks. The pile is pressed up to the gummer by an hydraulic ram g controlled by a valve j which is controlled by an electromagnet t in circuit with a spring contact bearing on the top of the pile, so that when a blank is withdrawn therefrom the ram is actuated to raise the pile. The separator nozzles 11, Fig. 5, are fitted on telescoping pipes 8 carried by a drum z, which is rotatable on a stationary vacuum pipe 12 provided with a port 15. Springs 41, Fig. 7, normally draw the fingers 38 into slots in the discs 33, but as the discs rotate, pins 39 bearing on stationary cams 36 project the fingers to press the blanks against the bands 16. Slidable bearings enable the discs 33 to be adjusted to blanks of different sizes, the discs being rotated by chain gearing from the shaft 22 of the bands 30. According to the Provisional Specification, the pile may be raised to the gummer by springs, and the gripping-device 38 may be replaced by a suction device.

Title: Process for the rapid removal of sulphur and silicon from pig iron
IPC: C21C1/02
Filed: 1954-08-27
Abstract: A method of removing silicon and sulphur from molten pig iron saturated with carbon and having a manganese/silicon ratio of at least 1.2:1 comprises charging the iron into a basic lined vessel, adding a neutral lime silica slag having a melting point below 2282 DEG F. and containing ferrous oxide, or manganese oxide, or mixtures thereof, and surface blowing with an oxygen-containing gas for sufficient time to remove the silicon and sulphur but without oxidising the carbon.  The amount of slag used may be between 25 and 100 lbs. per ton of metal and the oxygen containing gas, e.g. air, may be blown at 300-500 feet per second at an angle of 5 to 25 degrees to the horizontal surface of the metal.  The slag may consist of 25-40 per cent lime, 1.07 times the lime content of silica and the balance ferrous oxide and/or manganese oxide.  Magnesia may be substituted for lime up to 14 per cent of the total slag but must never be more than the lime content, and alumina may replace 20 per cent of the silica but must never be more than 6 per cent of the total slag.  The pig iron should be brought to the correct Mn/Si ratio before the slag is added.  The outlet end of the jets should not be more than two jet diameters above the metal surface.  The manganese content of the pig iron is also reduced.

Abstract: 634,883. Exhaust-silencers. WALLINGFORD, J. Sept. 17, 1947, No. 25329. Convention date, May 14. [Class 7 (ii)] An exhaust-silencer comprises an exhaust conduit, a housing forming a passage for a stream of secondary fluid different from the exhaust gases with an inlet and an outlet for the secondary fluid and means for circulating the secondary fluid through the housing and through a return passage connecting the inlet and outlet, the housing surrounding the end of the exhaust conduit and means being provided for causing the secondary fluid to take the form of a vortex into which the engine exhaust is introduced at a point beyond the beginning of the vortex the housing being provided with a separate outlet for the exhaust gases and the arrangement being such that the exhaust gases are arranged to mingle with the secondary fluid. As shown engine exhaust enters at 7 and leaves by a pipe 14. In a pipe 9 the exhaust mixes with a stream of fluid of greater specific gravity than the exhaust gases which is given a rotary motion by vanes 10. From the pipe 9 the fluid and the exhaust gases pass to a lower part of a casing 5 in which they are separated by baffles 11. The fluid collects in a sump 16 from which it is drawn by a pump 19 which then forces it into the pipe 9. The Specification as open to inspection under Sect. 91 comprises a modification in which an air inlet cone supplied with air as by the movement of a vehicle or aircraft in which the silencer is mounted supplies air to the inlet 21 instead of the fluid supplied by the pump and this air combines with the exhaust and the mixture is discharged through a common outlet. This subjectmatter does not appear in the Specification as accepted.
