Title: Improvements relating to supporting bushing insulators, particularly in electric current transformers
IPC: H01F38/30
Filed: 1932-07-06
Abstract: 404,017. Insulators. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London, and ADAMS, W. S., Tinto House, Crick Road, Hillmorton, Rugby. July 6,1932, No. 19133. [Class 36.] In a current transformer having a bar-type primary passing through a bushing insulator 5, the latter is resiliently supported within a casing 2 containing the core and secondary 3 in such manner as to be capable of limited angular movement with respect to the casing whilst restrained from material axial movement. The mounting comprises a resilient flange 9 adapted to fit between the casing wall and secondary 3, the flange being diametrically split and the two halves being held in a groove 8 on the bushing by being secured to a ring 10 of smaller diameter than the flange. A hole 6 of smaller diameter than the flange is provided in the casing wall, and in order that the bushing may be introduced after assembly, a notch 11 extending into the hole in the casing wall is provided to enable the flange to be passed through the hole by rotation after deforming the material of the flange adjacent the slit so that the flange passes through the notch. The method is stated to be applicable generally to resiliently mounting insulating bushings on panels.
Patent GB-191350-A (GB)
Abstract: 191,350. Haddan, A. J. H., (National Cash Register Co.). Oct. 4, 1921. Cash registers with operating-means and with several item-value totalizers. -In a machine provided with a number of sets or assemblages of totalizers, the engagement of one or more of the sets with the differential actuators is controlled not only by the depression of keys in the special banks, but also automatically by means of a pair of shaped plates which are positioned differentially at each operation in accordance with the particular keys depressed in the special banks, for example, the department and transaction bank. The depression of a key in either of these banks or in the clerks' bank will result in the selective positioning of the corresponding totalizer, but whether this particular totalizer will be engaged with the actuators depends upon the outlines of the shaped plates, and these are designed to meet the service requirements of the individual machine. The invention is described as applied to a machine having three lines or sets of totalizers 112 disposed around the differential actuators 110, each set comprising a number of totalizers having their numeral wheels arranged in groups by denominations, the particuar totalizer in a set being selected by an axial differential displacement of the totalizers by cam devices under the control of the keys. The set of totalizers is mounted in a carriage slidable along a shaft 140, Fig. 5, and is rocked into engagement with the actuators 110 when an arm 145 bearing a pin 146 is drawn along by a rotatable spider formed with hooks for seizing the pins 146 when these are displaced by the following mechanism. At each operation of the machine, a three-armed plate 157 is oscillated bv a cam 166 so as to rock three plates 159 pivoted at 1159 and provided with links 160 looped over pins 162 on the arms 145. The links are furnished with pins 167 adapted to cooperate with the adjacent edges of two shaped plates 168, 169. If the pins are not obstructed by these edges, the links 160 swing freely when the plates 159 are rocked and the pins 146 consequently are not displaced. On the other hand, if the pins 167 are blocked by the plates, the links swing outwardly and so carry the pins 146 within the path of movement of the hooks on the spider so that the oscillation of this spider produces the engagement of the totalizer set concerned. The plates 168, 169 are set differentially under the control of the transaction and department keys respectively, and are cut away at their edges so as to leave projecting portions corresponding with particular keys, according to the requirements of the machine. The pins 167 span the edges of both plates so that in order that a particular set of totalizers shall not be engaged, the corresponding pin 167 must be faced by cut-out portions of both plates. Specifications 8119/15, 191,346 and 191,351 are referred to.

IPC: C08B1/00
Filed: 1928-07-02
Abstract: 293,316. I. G. Farbenindustrie Akt.- Ges. June 30, 1927, [Convention date]. Carbohydrate esters and ethers.-In the manufacture of cellulose, starch and other carbohydrate esters and ethers, according to which as a first step the carbohydrate is converted into its alkali compound, air is removed from the carbohydrate material by passing through the vessel in which the carbohydrate is treated with caustic alkali, a current of gas or vapour which reacts with and is absorbed by alkali lye, for example, by treating with carbon monoxide, carbonic acid, formic acid, acetic acid, and formaldehyde, and then treating the carbohydrate with alkali solution. Removal of the air may be assisted by a vacuum. In examples, cellulose is treated in a vacuum chamber with carbon dioxide or acetaldehyde vapour, and afterwards with caustic soda solution; the swollen pulp is then etherified, for example, while supported between the layers of wire gauze as wound on a roller.

Title: Improvements in or relating to cooling devices for the oil systems of internal combustion engines
IPC: F01M5/00
Filed: 1943-11-22
Abstract: 575,425. Cooling systems and radiators for aircraft engines. BRITISH THERMOSTAT CO., Ltd., GREEN, W. E., and HURST, W. F. F. MARTIN-. Nov. 22, 1943, No. 19517. [Class 64 (iii)] [Also in Group XXIX] In an oil cooling system for an aircraft engine in which the cooler is surrounded by a by-pass jacket or chamber and has an adjustable shutter or shutters to control the flow of air through the main cooler, the opening and closing of the shutter or shutters is controlled by means responsive to the pressure of the circulating oil, and a thermostatic device disposed in the path of the oil leaving the cooler or its by-pass jacket or chamber causes movement of the shutter or shutters towards a closed position at a predetermined temperature. At the start, when cold oil enters the control device from a pump through the inlet 2, the pressure rises until it is sufficient to press the valve 5 back against the action of the springs 18, 22 until the part 6 is open. The rod 14, moving with the piston 5, closes, or actuates a hydraulic relay to close, the shutter or shutters. From the port 6, the oil passes through the outlet 9 to the jacket of the cooler, then through the inlet 12 into the chamber 11 containing waxfilled or similar thermostatic elements 32, 33, and finally returns through the outlet 13 to the reservoir from which the engine and pump derive their supplies. As the oil temperature rises, the element 32 expands and moves the integral valve elements 10, 27 towards the end 31, so gradually opening the outlet 29 to the cooler itself, and closing the outlet 9 and the port 6. From the cooler, the oil still returns to the chamber 11 through the port 12. As the temperature rises further, the port 29 is opened more and the pressure of the oil decreases. The piston 5 then moves back to the position shown and, through the rod 14, opens the shutter or shutters. If the temperature falls, the element 32 contracts, the outlets 9, 29 are opened and closed somewhat respectively, and the oil pressure increases to move the valve 5 and close the shutter or shutters. If there is congealing of the oil in the cooler, whilst the temperature of the oil in circulation remains high, the pressure rises and pushes the valve 5 to close the shutter or shutters, but the valve elements 10, 27 maintain the outlets 9, 29 closed and open respectively, so that the oil still has to pass through the cooler. The thermostatic element 33 is a safety element acting at a higher temperature than the element 32 if the latter fails. Specification 567,643 is referred to.
