Abstract: 562,888. Delivering heavy liquid. HOLMES & CO., Ltd., C. D., and PILKING- TON, F. S. Dec. 15, 1942, No. 17792. [Class 102 (ii)] Apparatus for delivering molten metal or other heavy liquid comprises a chamber containing a column of water, a lower port for the admission of heavy liquid, and an upper port opened to atmosphere, so that fluid under pressure fed to the upper end of the chamber, when these ports are closed, will act through the column of water and expel the heavy liquid through an outlet at the bottom of the chamber. The upper and lower ports are closed by non- return valves 5, 3 connected by a rod 8 of adjustable length to a double-acting control piston 10, a filter 14 being provided. Water enters at an inlet 16 with a non-return valve 17. The outlet 18 for the heavy liquid is screened, by a baffle plate 25 and leads to an adjustable delivery pipe 19 with interchangeable nozzles 20. Pressure fluid is supplied to the chamber 1 by an inlet 15 and to the control piston 10 by a valve 26. The chamber 1 is mounted in the inner of a pair of tanks 34, 35 and is held in position by rods 38 which pass through tubes 42 in the enlarged portion 13 of the chamber and are welded to the bottom of the tank. The temperature of the water inside the chamber is maintained by means of one or more circulatory pipes 41, each connected to the chamber at points one above the other. When compressed air is supplied through the valve 26 below the control piston 10, the valves 3, 5 are opened and heavy liquid enters the chamber through the valve 3, any heavy liquid in the delivery pipe 19 returning to the chamber. When compressed air is supplied above the piston 10, the valves 3, 5 are closed, and compressed air is then increasingly supplied to the chamber and the heavy liquid is discharged.

Patent GB-758061-A (GB)
Title: Improvements in or relating to carboxylic ester lubricating compositions
IPC: C07C69/34
Filed: 1954-06-18
Abstract: The invention comprises the ester product obtained by esterifying an aliphatic mono- or di-carboxylic acid with the primary alcohol obtained from the reaction of a secondary aliphatic monohydric alcohol and ethylene oxide, the said ester being selected to have an A.S.T.M. pour point below 35 DEG  F., a flash point above 300 DEG F., and a kinematic viscosity at 210 DEG  F. within the range of from 2 to 60 centistokes.  The preferred ester products are those having an A.S.T.M. pour point below about -15 DEG  F., a flash point above about 375 DEG  F., and a viscosity at 210 DEG  F. within the range of 2.6 to 13 centistokes.  Suitable mono- and di-carboxylic acids are caproic, 2-ethylbutyric, caprylic, 2-ethylhexoic, C8-oxo, pelargonic, capric, C10-oxo, lauric, C13-oxo, stearic, oleic, adipic, azelaic, sebacic and succinic acids.  The preferred dicarboxylic acids are those containing from 4 to 10 carbon atoms.  Secondary aliphatic alcohols which may be reacted with the ethylene oxide are those containing from 3 to 8 carbon atoms such as isopropyl and sec.-butyl alcohols, pentanol-2, pentanol-3, 3-methylbutanol-2, sec.-hexanols, sec.-heptanols, sec.-octanols including octanol-2 and sec.-alcohols derived from olefin hydration and by alkyl halide hydrolysis.  The ester products usually contain 20 to 130 carbon atoms, preferably 25 to 100 carbon atoms.  The reaction of the secondary aliphatic alcohol and ethylene oxide may be brought about by adding the ethylene oxide dropwise to the alcohol at a temperature of about 25 DEG  to 50 DEG F., preferably with agitation and a catalyst.  The resulting alcohol is of the formula RR1CHO(C2H4O)xH, wherein RR1CHO- is derived from the secondary aliphatic monohydric alcohol and x is an integer, and may then be esterified in a conventional manner with the aliphatic mono- or di-carboxylic acid.  The following esters are referred to: di-[2-2(21-caproxyethoxy) ethyl] adipate and di-[2-(21-isopropoxyethoxy) ethyl] adipate.ALSO:A lubricating composition contains the ester obtained from the esterification of an aliphatic mono- or di-carboxylic acid with the alcohol obtained from the reaction of a secondary aliphatic monohydric alcohol and ethylene oxide, the said ester being selected to have an A.S.T.M. pour point below 35 DEG F., a flash point above 300 DEG F., and a kinematic viscosity at 210 DEG F. within the range of from 2 to 60 centistokes. The esters may be added to natural oils such as mineral oils or oils derived from plants or animals, or to synthetic lubricants.  Suitable compositions are obtained by blending the esters with other dibasic acid esters such as primary alcohol esters of adipic, sebacic, glutaric and succinic acids, and with complex esters such as the alcoho-dibasic acid-glycol-dibasic acidalcohol esters.  The compositions may be thickened with grease forming soaps.  Other additives which may be added to the compositions are rust, corrosion and oxidation inhibitors, viscosity index improvers, and load carrying and antiwear agents.

Abstract: 1,183,380. Capacitor binary storage circuits. TOKYO SHIBAURA DENKI K.K. 19 April, 1967 [4 May, 1966; 16 May, 1966], No. 18040/67. Heading H3T. [Also in Division G4] A binary digit storage capacitor C o  is connected at one terminal to write and read transistors T a , Tb and at its other terminals through oppositely poled diodes D 1 , D 2  to an output t 4  and an input t 3  of a bi-stable circuit. Information is stored in the capacitor by first setting the bi-stable circuit to a desired state and then pulsing the write transistor T a . If the bi-stable circuit is in its set state, e.g. if the output at terminal t 4  is zero, the capacitor will charge, e.g. to the negative voltage - E, whereas if it is the reset state, e.g. if the voltage at t 4  is - E the capacitor will not charge. To read out the state of the charge the transistor T b  is pulsed and if the capacitor is charged it will discharge through diode D 1  to condition the bi-stable circuit to its set state, assuming it is not already there. In order to ensure that the bi-stable circuit is conditioned during read out to its reset state when there is no charge on the capacitor, the reset pulse may be applied to the bi-stable circuit concurrent with read out and of such short duration that it is overridden by a set pulse from the capacitor (as described with reference to Fig. 4). A matrix of such stores may be arranged with n columns for n decimal digits and four rows for the binary representation of the digits (Fig. 3, not shown). Fig. 4 shows a similarly arranged but larger store in which the bi-stable circuits (RWR1, RWR2, &c.) are common to each row and the read-out and write transistors (TR 2 , TW 2 , &c.) are common to each column. A counter CTR enables read out, write and restoration of charge leakage to be effective simultaneously for all stores in a column but in the respective columns cyclically or one at a time. A strobe pulse Sp operates the counter and provides the narrow reset pulses for the bi-stable circuits and a "write strobe" times the application of the write pulses. Two decimal numbers may be added and subtracted by a circuit comprising two decimal registers XY (Fig. 9) of the type described with reference to Fig. 3, having their bi-stable circuits connected to an adder so that the addition is returned to register X.

Abstract: 1388020 Pressure die casting IDRA-PRESSEN GmbH 18 April 1972 [29 April 1971] 18565/74 Divided out of 1388019 Heading B3F In a method of pressure die-casting using a cold chamber machine having a multiplier piston 1 and in which pressure is applied to the metal in phases, the time required to build up the pressure applied by the multiplier piston 1 in a third phase is independent of the speed of the shot piston during the second phase. During a first phase fluid pressure from a pump P is applied to a longitudinal bore 3 in the multiplier piston 1 and acts on a press piston 4 to cause a relatively slow movement thereof. After a given time or after the press piston has reached a given position, the valves 6 and 12 are actuated. Operation of the valve 6 actuates a further valve 5 to allow pressure medium from a reservoir 7 to flow via lines 8, 9 and 10 to a space 11 and thus to the bore 3. The increased pressure now acting on the press piston 4 causes the piston 4 to move more rapidly during the second phase of the metal injection process. The speed may be controlled by adjustment of a spindle 34. When the mould has been filled, the pressure in the space 1 rises and causes a valve 15 to change over. This opens the space 16 to atmospheric pressure this permitting a piston 13 to move to the right and the pressure fluid in the reservoir 7 to flow directly to the space 11 and act on the multiplier piston 1 which begins to move to the left as soon as the counter pressure in a space 20 has been overcome. The rate of supply of pressure fluid from the reservoir 7 to the space 11 is determined by the stroke of the piston 13. This may be adjusted by a hand wheel 19. In another embodiment, the valve 5 is combined, with the piston 13 and in a further embodiment the valve 12 is omitted its function being carried out by the valve 6.
