Abstract: An hydraulic transmission liquid composition consists of (i) a polymer of n-octyl fumarate prepared by a method claimed in the parent Specification (ii) 2-ethyl-hexyl silicate, (iii) a polyalkylmethacrylate or dimethylpolysiloxane, and (iv) a pair of additives which are compatible, one being an antioxidant, the other `anti-wear.  The polyalkylmethacrylate preferably has alkyl groups of 6C, but 8-10C alkyl groups are also mentioned.  The antioxidants specified are Ortholeum 300 (a mixture of complex organic amines), catechol, pyrogallol and a -naphthol. `Anti-wear' additives specified are ethylene glycol-, isopropyl, or isoamyl ricinoleate, 2-ethylhexyl sebacate Santolube AR (a long chain aliphatic diether: "Santolube" is a Registered Trade Mark), Alox 1669 (a mixture of methyl esters of oxidized petroleum hydrocarbons), Hypol (a mineral oil solution of chlorine, phosphorus and sulphur), Crezol Z5 (a commercial product containing a substantial quantity of lecithin), tricresyl phosphate, dichloronaphthalene and Cereclor 70 (a chlorinated paraffin wax which may include a little CC14; "Cereclor" is a Registered Trade Mark). `Anti-wear' additives are defined as being those, which owing to their chemical structure, are capable of facilitating the slipping on one another of metal parts in relative movement immersed or in contact with an hydraulic liquid composition.ALSO:An hydraulic transmission liquid composition consists of (i) a polymer of n-octyl fumarate prepared by a method claimed in the parent Specification, (ii) 2-ethyl-hexyl silicate, (iii) a polyalkylmethacrylate or dimethylpolysiloxane, and (iv) a pair of additives which are compatable, one being an anti-oxidant, the other an anti-wear additive.

Title: Improvements relating to the insulation of electrical equipment
IPC: H05G1/00
Filed: 1951-06-27
Abstract: 693,471. Supply systems for X-ray apparatus; transformers;. rectifying. METROPOLITANVICKERS ELECTRICAL CO., Ltd. June 27. 1951 [June 30, 1950], No. 15264/51. Classes 38 (ii) and 38 (iv). [Also in Groups XX and XXXVI] The elements of a transformer rectifier system for use with X-ray apparatus are mounted on a lightweight frame 12 enclosed in an open-topped tank 13. The top 14 of the frame forms the cover for the tank, which is filled with sulphur hexafluoride or other carbon-free gas having a higher dielectric constant and appreciably greater density than air, the gas being at substantially atmospheric pressure. The cover 14 has bushings 17, 171, 18, 181 for the passage of H.T. cables and a terminal block 19 for L.T. connections. Transformer 22 has a low voltage p imary 23 energized through block 19, either directly or through control circuits. The secondary comprises a pair of coils 25, 26 having a common central connection through the transformer frame to the tank 13. An adjustable spark-over protective gap 27 is also provided. The windings 25, 26 are connected to the input side of a fullwave rectifier system 30 comprising rectifiers 31, the filaments of which are energized from a filament transformer 33. The centre tapped secondary of a filament transformer 36 is connected with the blades of a triple pole double throw switch 38 through which connection may be selectively made with the cathode filaments of X-ray tubes 35, 35<SP>1</SP>. One side 39 of the power supply is connected with one of the blades of switch 38 for connection with the cathode of the tube with which the transformer 36 is connected, while the other side 40 is connected with a double throw switch 41 operating in unison with switch 38 to connect the system with one of the tubes. The switches are manually operated from outside tank 13. After assembly of the transformer-rectifier system in the tank 13, the tank is filled with sulphur hexafluoride, as by passing a hose from a supply cylinder through an opening 20 in cover 14 to the bottom of the tank, the opening being closed when the container is full of gas. As the gas is fed into the tank the air is pushed out through the opening 20. The rectifiers may be mounted near a removable cover in the base of the tank, to permit easy replacement.
