Title: Improvements in or relating to poultry drinking apparatus
Inventor: LEEMING DAVID CHRISTOPHER
IPC: A01K39/02
Filed: 1970-04-29
Abstract: 1,274,415. Poultry drinking apparatus. D. C. LEEMING. 19 April, 1971 [29 April, 1970], No. 20685/70. Heading A1M In poultry drinking apparatus water is supplied from a reservoir 11 along pipe 21 to troughs 27. Closed chambers 24 are supplied with water by pipes 23 which discharge below the water levels defined by outlet pipes 28; these pipes ending below the level of the water in troughs 27. A state of equilibrium normally exists in which the heads of water A, A' pushing up the water level in the chambers are equalled by the heads B, B' pushing down the level via air in pipes 28 and the chamber. If water is taken from a trough head B, B' is decreased and head A, A' can push up the level so that water can trickle into trough 27 to restore equilibrium. The opening of pipe 28 is restricted so that the water will not enter so quickly as to interrupt the air column. The depth of water in the trough may be adjusted by raising or lowering the chamber to change head A, A'. In a modification (Figs. 2, 3, 4 not shown) an inverted cup member (42) immersed in water forms the chamber; water entering through the open base and an outlet pipe extending up into it. The drinking receptacle is a horizontal pipe (40) having peck-valve controlled outlets (41) and with an upward extension (45) at the end remote from the chamber to provide the counter-acting head of water.

Title: Process for the manufacture of carbonyl compounds
IPC: C07C45/34
Filed: 1958-06-27
Abstract: Carbonyl compounds, in particular aldehydes and ketones, are prepared by contacting an olefinically unsaturated hydrocarbon with an aqueous solution containing a compound of a metal of the platinum group at a temperature of 0-200 DEG C. in the presence of an oxidising agent having an oxidation potential higher than that of the platinum group metal compound in the solution.  Preferably the halides, sulphates or phosphates of the platinum group metal are used.  Suitable oxidising agents are, for example, persulphates, oxygen acids of halogens and their salts, chromates and other oxyacid salts, and salts of multivalent metals.  The process is preferably carried out at a pressure of 1-50 atm.  The process is applicable to aliphatic, cycloaliphatic and aromatic substituted olefinically unsaturated hydrocarbons as well as diolefinic hydrocarbons.  Among the compounds of the platinum group metals used are salts of palladium, rhodium, ruthenium, iridium, rhodium, and chloroplatinic acid.  The oxidising agents used include ferric sulphate, potassium persulphate, potassium dichromate, cupric sulphate, cupric acetate, potassium bromate, potassium periodate and ferric chloride.

Patent GB-212610-A (GB)
Abstract: 212,610. Relay Automatic Telephone Co., Ltd., and Johnson, B. B. Dec. 1, 1922. Automatic and semi-automatic exchange systems; coin-freed systems; metering systems.-A junction extending from an automatic or semiautomatic exchange to a manual exchange is provided at the latter with a calling device which is operated differentially according to the character of the calling line on the automatic exchange or according to the class of service required by the calling party. Thus calling lamps may be selectively lit at an operator's position to indicate that the calling line is an ordinary line or a coin-box line, or lamps may be lit at different positions, such as an enquiry position or an ordinary B- position, according to the service required. Metering can be effected for certain classes only. A single group of junctions to the manual exchange can therefore be used for the two classes of call. The condition of the junction is modified according to the class of line by which it is taken into use, or according to the digit dialled by the calling party, by arranging that in one case battery is connected to the a-lead and in the other to the b-lead. Indicating class of calling line. An ordinary subscriber is connected in known manner to an idle current-feeding group ABF, Fig. 3, and thence over connecting apparatus, such as relays, indicated at X, X. Fig. 3, to a junction COJ to the manual exchange. Relays C, D, Fig. 4, energize over circuits 3, 2, respectively, and cause the self-locking relay E to close a circuit 5 over the b-lead of the junction for relay LE1, Fig. 4A, which lights lamp LW. A call from a coin-box line is extended to a different feeding group, relays C1, D1, E1 being energized. Relay E1 closes a circuit 9 over the a-lead of the junction for relay LE2 which lights lamp LR. In each case the insertion of an answering plug energizes the cut-off relay CO. The feeding group of a coin-box line is similar to that described in Speci. fication 211,231. Indicating class of service required. If the subscriber dials digit O, he is connected in known manner to the junction OJ, Fig. 5, leading to the manual exchange, relays C, D operating as before, and relay E closing a circuit over the b lead to energize relay LEI and light lamps LW. If, however, the subscriber dials the digit 9 to select the enquiry operator, the call is extended to the same junction but an additional relay MX in the recorder energizes a self-locking relay RL which reverses the connections to the junction so that relay E closes a circuit 9 over the a-lead to energize relay LE2 and light lamp LR at the enquiry position. Specifications 142,265 and 212,682 are also referred to.

Abstract: 755,066. Making wire coils; shearing. HELI-COIL CORPORATION. July 22, 1954 [Sept. 18, 1963], No. 21377/54. Classes 83 (2) and 83 (4). Wire coils, such as screw-thread inserts, are made by continuously coiling wire advancing to coiling means, guiding the coil so formed to gripping means, spaced from the coiling means, which intermittently grip the leading end part, of the coil and allow a predetermined length to be severed therefrom. Wire 13 is fed to a continuously operating coiling machine 12, driven by an electric motor 16, and is formed thereby into a continuous coil 29 which is guided by a tube 28, slightly wider than the coil, to intermittently operated gripping and severing means 11. These comprise an upper pair of jaws 20, 21 the jaw 20 being fixed and the jaw 21 being slidable thereto and from by a slide 45 reciprocated by a cam 67 on a onerevolution shaft 50, a lower pair of jaws 22, 23, the jaw 22 being fixed on an intermittently rotated table 24 and the jaw 23 slidable thereto by the slide 45, and a cutter blade 41 secured to the slide 45 to move between the upper and lower jaws. The leading end of the coil 29 is fed down through the open jaws and after a predetermined length of wire 13 has been fed to the coiling machine 12 a switch 18 is closed to energize a solenoid 105, Fig. 4, to engage a clutch 94, bn the shaft 50, driven from the motor 16. As the cam 67 on the shaft 50 rotates, the slide 45 is pushed forward to close the upper and lower jaws, to raise, through links 59, a rod 42 within the coil, and to cause the blade 41, in co-operation with the top of the rod 42, to sever the coil. The lower jaws are held closed by a catch 70, to hold the severed coil and, on continued rotation of the shaft 50, a quadrant 91 thereon causes, through gearing 84, the table 24 to turn 60 degrees to present another pair of jaws 22, 23, opened by engagement of the catch 70 with an abutment, below the jaws 20, 21 which are then opened. The clutch 94 is then disengaged to stop the shaft 50 until the switch 18 is again closed after a predetermined length of wire 13 has been fed to the coiling machine; current to the solenoid 105 having passed during the one revolution of the shaft 50 through a contact arm 111 on the shaft and a fixed arcuate contact 113 having an insulated spot which when engaged by the arm 111 interrupts the current to the solenoid 105. The table 24 and lower jaws may be dispensed with and the severed coil allowed to drop away from the severing means. U.S.A. Specification 2,541,232 is referred to.
