Title: Improvements in and relating to railway rail anchors
IPC: E01B13/02
Filed: 1947-07-11
Abstract: 651,204. Creep anchors. AMERICAN FORK & HOE CO. July 11, 1947, No. 18491. Con. vention date, Dec. 6, 1946. [Class 104 (ii)] A railway rail-creep anchor having a U- shaped clamp member 1, the limbs of which are slotted at 10 to fit the rail flange 20 is secured by a straight retaining bar 3 with a hook-form front end 4 adapted to snap over the far edge 21 of the rail flange and having a middle bow portion 6 which cams along a bent-over loop 12f extending integrally from the base 11 of the U, the bent-over end 12d of such loop reaching inwardly to the web 11. The upper portions of the limbs 7, 8 are offset inwardly to retain the bar 3 which is arranged to lie below inward protuberances 38 at the edges 13 and above inward protuberances 71a at the edges 15 of the U- shaped clamp member 1. The slots in the limbs are such that the U-shaped clamp which bears against the side of the sleeper to prevent creep is disposed at 70 degrees to the rail flange. The bow portion 6 of the retaining-bar has an angular size of 104 degrees. Specification 651,201 is referred to.

Title: Improvements in or relating to arrangements for controlling and/or metering the flow of a liquid
Inventor: THURSTON BRYAN OLIVER
IPC: G01F1/00
Filed: 1960-05-25
Abstract: 981,334. Liquid flowmeters. SANGAMO WESTON Ltd. May 24, 1961 [May 25, 1960], No. 18513/60. Heading G1R. An arrangement for controlling and/or metering liquid flow comprises a downward flow-pipe 19 having means 20 between its ends for indicating or sensing the position of the top 33 of a column of liquid therein, a discharge control valve 25 or jet in the lower end of the flow path 24 from the flow pipe 19, jet or other flow restriction 13 in the liquid supply path 15 to the flow pipe, one of the said jets &c., being of precisely known flow characteristics and at least one jet &c., being variable to adjust the flow to a vlaue at which the restricted liquid input to the flow-pipe 19 is just sufficient to maintain a column of liquid in the flow tube at a given datum level 33. A pump 31 raises liquid from a sump 29 to a tank 10 whence it flows by way of a float chamber 12 (float not shown) for providing a head of liquid nl to a jet 13 which is to be calibrated in a pipe 15 shaped to avoid airlocks, and thence to a constant level weir 17 in a level tank 16 leading into the inlet pipe 19. A closed chamber 21 at the box of the pipe 19 is provided with a cock 22 and vent pipe 23 for bleeding off trapped air. The means 25 is a variable jet whose flow characteristics are precisely known and which opens into a constant level tank 26 with a weir 27 whose distance n2 below the indicator 20 defines the liquid level 33. By manipulating the variable jet 25 inlet the lever 33 is constant the rate of flow through the jet 13 may be determined. In a form of the apparatus shown in Fig. 2 the chamber 21 is omitted and the height of the liquid at the indicator 20 is detected at 35 by photo-electric, electrical-resistance or other means. A signal so obtained is amplified at 36 to operate a servomotor 37 which may either vary the jet 25a to match flow from the jet 13a as a monitoring device as in Fig. 2 or control flow through a variable jet at 13a to match a predetermined setting of a variable jet at 25a (Fig. 3 not shown). Means may also be included for varying the datum level 33 to compensate for changes in temperature or viscosity of the liquid. In a pressurized system back-pressure of air or gas may be provided in the chambers at 10, 12, 16, 26 and 29.

Title: Organo-siloxanes and method of making same
IPC: C08G77/06
Filed: 1946-06-20
Abstract: Organo siloxanes of general formula <FORM:0618459/IV(a)/1> where R represents a lower alkyl radical, R1 and R11 each represent an alkyl or a monovalent aromatic radical, and n is an integer greater than 1, are prepared by partially hydrolysing a dialkoxysilane having the formula <FORM:0618459/IV(a)/2> with from 0.5 to 1.2 mols. of water per mol. of the dialkoxysilane.  The products are useful as dielectrics or for rendering solid hydrophilic materials water repellant.  Preferably the hydrolysis is performed in neutral solution or not more than 0.1 gram-equivalent of an alkali, e.g. sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, or lime, is employed as the catalyst.  The mixture may be heated to 70 DEG -150 DEG  C., or to a temperature such that the alcohol formed will distil off.  In example (1), dimethyl diethoxysilane was hydrolysed with aqueous ethyl alcohol.  Alcohol was distilled off, the distillate diluted with water to yield an oil from which cyclic dimethyl siloxane trimer was crystallised, the residual oil being added to the distillation residue which was then fractionated, and in (2) the same siloxane as used in example (1) was hydrolysed in the presence of caustic soda, the alkali neutralised with carbon dioxide and the product fractionally distilled.  A number of ethoxy end-blocked siloxanes with different values of n were isolated.  Tests are described for comparing different methods of removing alkali from alkaline-hydrolysis products and for comparing the effects of using different quantities of water for hydrolysis. The physical properties of the various isolates are tabulated in the Specification.  Other starting materials mentioned are lauryl methyl diethoxy silane; phenyl methyl diethoxy silane; lauryl methyl dimethoxy silane; phenyl methyl dimethoxy silane; dimethyl dimethoxy silane; dipropyl diethoxy silane; dibutyl dipropoxysilane. Specifications 563,995 and 572,331 are referred to.

Abstract: 1,149,901. Electrostatic charge images. EASTMAN KODAK CO. April 29, 1966 [April 30, 1965], No.18822/66. Headings G2H and G2J. Developable electrostatic charge images are formed on insulating surfaces by directing a flow of ions (e.g. from a corona discharge) through an ion-permeable array having an image pattern of insulating and conductive areas which modulates the ion flow in accordance with the image pattern. The array may be electrically biased and preferably comprises a conductive grid coated with a photoconductor optionally together with an insulator, the image pattern being formed by imagewise exposure. The charge image may be formed by either full frame or line-by-line techniques and developed with a conventional powder or liquid developer or by using an ion sensitive layer; the developed image may be fixed or transferred. Multi-colour images may be formed by using a grid which has been imagewise exposed through a primary colour filter, developing the charge image formed with a complementary colour developer, repeating using filters and developers of the other primary or complementary colours and optionally forming a black image. An optical system for line-by-line exposure comprises (Fig. 18) an array of truncated erecting prisms (464) each associated with a convex lens (466).

Abstract: 642,882. Road-vehicle spring-suspensions. OSTER, L. E. W., MONTROSE-, and POLLOPAS PATENTS, Ltd. July 27, 1945, No. 19301. Convention date, Sept. 5, 1941. [Class 108 (ii)] In a suspension particularly for rear wheels of vehicles which move mainly in a forward direction, the rear wheel axis is constrained to move in a straight or curved trajectory in such a way that the angles # formed by the perpendiculars to the tangent to the trajectory, with the road surface, are not less and are preferably greater than, the angles # formed by the line joining the centre of gravity of the vehicle and the wheel axis, with the road surface. In the case of a curved trajectory the angles # increase with increasing upward wheel deflection. In the form shown in Fig. 1d the wheel bearing 3 is guided by slides 2 against the action of a coiled spring (not shown). In a second construction (Fig. 2, not shown) the wheel is carried by a link which slopes downwardly and rearwardly to a pivotal point on the chassis. In a third construction (Fig. 3, not shown) the wheel is connected to the chassis by a watt parallel linkage. On deceleration the rear end of the vehicle tends to move downwardly and on curves lateral canting is less pronounced since only a component of the static load acts in the direction of action of the resilient member.
