Title: Improvements in fluid operated brake apparatus for vehicles
IPC: F16D57/06
Filed: 1926-04-07
Abstract: 265,907. Staude, E. G. Feb. 15, 1926, [Convention date]. Fluid - pressure.-In fluid-pressure brakeoperating apparatus for vehicles comprising a control for operating the brakes, connected in the fluid-circulating system of a pump adapted to be driven in opposite directions for example by the motion of the vehicle, a single device is provided to render the pump effective regardless of the direction in which the pump is driven. The pump, as shown in Fig. 4, comprises gear wheels 10, 11 mounted in a casing 8 secured on the casing of the transmission gear of a motor vehicle, the wheel 10 being carried by a sleeve 14 splined on the transmission shaft 12 and the wheel 11 by a boss 17 on the casing 8. The intake of fluid from the transmission casing is situated at 19 and fluid is supplied to the wheel 11 at 20 and to the wheel 10 through the channel 21 and port 22. The delivery port 29 is located in a chamber 25 containing a vertically reciprocating valve 26. When the gear wheel 10 is rotated in the clockwise direction pressure is built up at 23 and applied to the valve 26 through the passages 24. 27 so that it is forced down to the lower end of the chamber 25 thus connecting the delivery port 29 to the passage 24. Rotation of the wheel 10 in the counter-clockwise direction causes pressure to be built up at 30 to which pressure is transferred by ports 31, 33 and channel 32 to the chamber 34 to force the valve 26 into the position shown and thus connect the delivery port 29 to the point 30. Pressure fluid leaking along the shaft 12 is prevented from building up a pressure at 71. Fig. 12. by channels 72, 73 leading back to the transmission casing 2. Pressure fluid is delivered from the port 29 to the chamber 44, Fig. 7, of a combined valve and brake operating device 42, 54 constructed and operating in substantially the same manner as described in Specification 262,709, the connection between the brake arm 60 and pedal 5 comprising a tension spring 63 in place of the connection controlled by a compression spring described in the prior Specification.

Title: Improvements in or relating to inductance coils having ferromagnetic cores
Inventor: PIERROT ANDRE
IPC: H01F17/04
Filed: 1954-03-30
Abstract: 751,037. Inductors. LIGNES TELEGRAPHIQUES ET TELEPHONIQUES. March 30, 1954 [April 23, 1953], No. 9324/54. Class 38 (2). An inductor, especially a loading coil for telecommunications circuits, has a magnetic core of ferrite material having values of permeability Á. of at least 2400, a Curie temperature of approximately 190‹ C. and values of F n /Á, h/Á<SP>2</SP>, t/Á and αÁ lower than 0.0005, 0.001, 0.001 and 0.002 respectively, where F n , h, t and αÁ are eddy current loss, hysteresis loss, residual loss and temperature coefficient of permeability as defined. A suitable material is that forming the subject of Specification 730,703. The core may be a pot with a central stem having an air gap, either built up from parts, Fig. 1 (not shown), or made in two halves either moulded or machined in the manner described in Specification 737,068, Fig. 10. The halves may be bolted together, Fig. 9 (not shown), or cemented together. They may be arranged for mutual rotation to vary the effective length of an oblique air gap. The windings may comprise single wires distributed in two or four compartments of a plastic former for side and phantom circuit coils respectively, Figs. 3, 4 (not shown). For better balance the windings may be wound together, Figs. 5-7 (not shown). The number of turns and size of wire may be less than in conventional coils, thus reducing mutual capacitance. The conductors may be insulated with enamel, varnish or plastic material which welds together, and the coil may be embedded in plastic such as polyamide or polystyrol, no former being needed. The windings may be insulated with vinyl chloride or polyethylene and surrounded by a polystyrol band cemented to the former: If preferred the windings may be impregnated or immersed in oil, or coated or filled with polyesters such as Araldite (R.T.M.) afterwards polymerized. Alternatively the coil may be filled with nitrogen. Two side-circuit and one phantom-circuit coil units may be clamped together between flanges 47, Fig. 11, or cemented together. To reduce magnetic coupling between adjacent units they may be separated or surrounded by a screen such as an iron washer, sheet of Permalloy C, or Mumetal (Registered Trade Mark), Figs. 12, 15-25 (not shown). They may be coated by injection moulding with an external cylindrical or octagonal plastic coating, Fig. 13 (not shown). The loading coils may be located inside the cables or joints, without external casings. A number of composite arrangements are described in detail and their properties tabulated. Specification 730,703 also is referred to.

Blowing. - An automatic turnover blowing- machine is constructed with upper and lower tables moving together by a step-by-step motion round a central column. The upper table carries a series of neck and inverted parison moulds and the lower table carries a corresponding series of blowing moulds. The machine is mounted on a wheeled base running on rails so that it can be brought up to the melting tank, from which the glass is delivered. The severing devices for the glass may be of the kind described in Specification 128,172. The tables move through eight steps, the sequence of operations being as follows :-(1) A gob of glass is dropped into one of the parison moulds. (2) A blow-head is applied to the mould and air is admitted to force the glass into the neck mould, the neck-piercing plunger is withdrawn and a puff of air is admitted to cool the inside of the neck. (3) A cap is applied to close the mould and a preliminary blowing is effected. (4) The mould is opened. (5) The neck mould is turned on a horizontal axis so as to swing the parison through 180 degrees. (6) The blowing mould is closed on the parison. (7) The bottle is blown. (8) The blowing mould is opened and the bottle discharged. The parison moulds are filled in succession so that eight articles are being produced at the same time. Fig. 1 is a sectional elevation of the machine. A base 50 mounted on wheels carries a central standard 41 on which are mounted the tables 44 and 45 driven by an oscillating cam frame 49 actuated from a motor. The frame 49 is driven in any suitable manner, but preferably by the mechanism described in Specification 128,172. The table 44 carries columns 46 on which the table 45 may be vertically adjusted by a screw &c. 228 for making bottles &c. of different length.

Abstract: 489,125. Photographic view finders; reflex cameras. KILBURN, B. E. D. (Leitz Ges., E.) April 6, 1937, No. 9810. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 22, 1937.] [Class 98 (i)] A direct-vision finder comprises a movable reflex mirror, which reflects the image formed by the camera objective to a viewing system consisting of an eyepiece close to the camera, reflecting surfaces which deflect the rays round a closed figure having two sides intersecting at right-angles, and an objective situated in the part of the ray-path forming the closed figure. The construction shown is adapted to be interposed between the body B and lens B<1> of a camera to convert it to reflex type. A<1> is the movable reflex mirror reflecting the image from the lens B<1> to a ground glass screen C. The rays from this image pass through a collecting lens F to a prism reflector G which reflects them through an objective D to a prism reflector H which in turn reflects them to the eyepiece E. The objective D may be moved to the dotted position, thereby altering the magnification, so that the image may be viewed either as a whole, or in part at increased magnification for sharp focusing.

Filed: 1973-02-28
Abstract: 1418344 Valves A WOBIG 28 Feb 1973 [1 March 1972] 9831/73 Heading F2V [Also in Division F4] A valve for controlling a hot water radiator in a single-pipe heating system has an inlet connection 14 to the main supply pipe, an outlet connection 19 and a two-way connector 18 for the supply to and the return from the radiator, the return flow being via a guide piece 24, which is of poor heat-conducting material and may be extended as necessary by an immersion tube 15. The hollow axially sliding valve member 16 is guided by the member 13. As shown, the valve is positioned to cut off the return flow from the radiator, gap 17 being closed, and to open direct by-pass flow between the inlet and outlet connections 14, 19. If the valve member 16 is moved to contact heating surface 20 bypass flow is cut off and the gap 17 opened to per mit flow through the radiator. The guide member 13 extends into the chamber 12 and the annular gap a is made equal to or smaller than the gap b so that dirt particles cannot flow through the gap a and block the valve when it is opened to provide by-pass flow i.e. when the radiator is cut off. These particles are, instead, retained within the chamber 12 until the valve is next operated to provide flow into the radiator whereupon any retained particles are washed through and deposited in the radiator. Various embodiments of the guide piece are described, some including devices to suppress convection currents.

Title: Improvements relating to the Preparation of Amines.
Filed: 1918-06-15
Abstract: 128,372. Rintoul, W., Thomas, J., and Nobel's Exlosives Co. June 15, 1918. Amines.-Tertiary amines are separated from admixed secondary amines by treating the mixture at low temperature with phosgene to convert the secondary amine into the corresponding urea chloride; if the tertiary amine is present in excess, the separation can be effected in one stage, the mixture of urea chloride, tertiary amine hydrochloride and free tertiary base being washed with dilute hydrochloric acid which extracts all the tertiary base as hydrochloride, which is then decomposed by alkali. If the secondary base is in excess in the mixture, either free tertiary base is added until there is excess thereof and the resulting mixture is treated as above, or the initial mixture is treated with half the equivalent of phosgene, the product is washed with water to extract the hydrochlorides of the bases, and the bases precipitated from this solution by alkali, and subjected again to the action of phosgene, and the operations repeated until the separation is complete. The secondary bases are regenerated from the urea chlorides by hydrolysis by boiling with dilute acid or water. Examples are given of the treatment of crude diethylaniline containing moncethylaniline and of a mixture of mono- and di-ethyl-o-toluidine.
