Title: Improvements in or relating to vehicle braking systems
IPC: B60T11/10
Filed: 1936-09-18
Abstract: 481,608. Fluid - pressure brakes. AUTOMOTIVE PRODUCTS CO., Ltd., PARNELL, F. G., and MARTINDALE, A. F. Sept. 18, 1936, No. 25466. [Class 103 (i)] A vehicle brake system comprises duplicate hydraulic transmission systems operated by a booster device, such as a friction clutch driven from the road wheels, and a mechanical connection from the pedal or other controlling member of the booster to some or all of the brakes so as to provide direct operation of such brakes. In the system shown, each front brake is operated by a cylinder having unequal pistons 22, 23 working in separate chambers and connected respectively to the shoes, the larger piston being connected to the trailing shoe 15. The booster comprises a friction clutch driven by a shaft 36 geared to the road wheels or other part of the mechanism and operating, for example, in the manner described in Specification 235,387, [Class 103 (i)]. It comprises a friction disc 40 between a disc 37 fixed to the shaft and a disc 38 slidably splined to the shaft. Collars 43, 44 freely mounted on the shaft and provided with interengaging cam surfaces have arms 41, 42 connected respectively to the pedal 47 and by a T-lever 50 to cams 33 of the rear wheel brakes. An arm 56 on the disc 40 is connected to the piston 58 of a tandem master cylinder such as described in Specification 446,364, the space 61 of which is connected by pipe 65 to chambers 20 of the front wheel brake cylinders while the space 62 which is separated from space 61 by the floating piston 60 is connected by pipe 66 to cylinders 30 of the rear wheel brakes and to chambers 19 of the front brake cylinders. Depression of the pedal by turning collar 43 and by reason of the cam surfaces 431 and a fixed abutment 45 engages the clutch, thereby operating the master cylinder to apply all the brakes, while at the same time the collar 44 is turned to apply the rear brakes by the cams 33. Leakage in the pipe 65 thus only puts the shoes 15 out of action, leakage in pipe 66 only puts the shoes 14 out of action, while in the event of failure of the booster device the rear brakes will still be applied by the cams 33. A vacuum or pressure fluid booster may be substituted for that shown. Independent cylinders may be provided for the respective shoes of the rear brakes as well as, or instead of. for those of the front brakes. Separate master cylinders operated by a common booster device may be used instead of the master cylinder shown. The cylinders of the rear brakes and the lever 50 may operate these brakes through a common cam lever.

Title: Improvements in or relating to method for separating the components of gaseous mixtures mixtures in fluidized adsorption system
IPC: C07C7/12
Filed: 1954-09-02
Abstract: Gaseous components of a mixture are separated by means of a fluidized solid adsorbent by passing said mixture into the absorption section of a column consisting from top to bottom of sections for (a) disengaging, cooling, absorption, rectifying, desorption and dehydration, or for (b) disengaging, adsorption, rectification desorption, dehydration and cooling, whilst the adsorbent passes downwardly through said sections.  Tail gas is passed from the disengaging section to the dehydrating section (in arrangement (b), via the cooling section) to contact the wet adsorbent passing therethrough, and is also used to recirculate by entrainment the adsorbent from the lowest section to the disengaging section; in arrangement (b) part of this gas is withdrawn as the less adsorbed product gas but in arrangement (a) the latter is withdrawn from the upper part of the adsorption section; from the rectifying section an intermediate fraction or fractions, if present, are withdrawn; heat and stripping steam are applied to the desorption section, and steam and the more adsorbable component withdrawn therefrom; from the dehydrating section, a stream of mixed gases and steam is withdrawn, which may be added after drying to the tail gases from the disengaging section; all or a part of said mixed gases may alternatively in arrangement (a) be introduced into an intermediate section of the adsorption section.  In one embodiment of arrangement (a), gas in addition to that required as less adsorbed product is withdrawn from the adsorption section and added to the tail gas, and this mixture used to assist fluidization in the cooling zone in addition to its use for dehydration and recirculation.  It is stated that the whole of the wet product gases may be removed from the desorption section, dried and returned to the rectification section after removal of heavy fractions, in arrangement (a). Mixtures to which the process can be applied are:- separations between individual hydrocarbons as in residual gases from cracking of all kinds, separation of gases such as hydrogen and nitrogen from hydrocarbons (activated carbon adsorbent may be used), particularly the products of hydroforming; benzene and an inert carrier such as air, hydrogen and nitrogen; nitrogen and methane.

Title: Improvements relating to the loading of natural silk
IPC: D06M11/20
Filed: 1930-10-03
Abstract: The process of the parent Specification is modified in that the hydrogen ion concentration of the bath containing the loading metal salt is adjusted to a pH value of 0,8-2,1 at room temperature and is constantly maintained at such a value.  With rise of temperature the pH value is lowered so that at 50 DEG  C. it is about 0,4-1,7.  In an example the debasted silk is treated for 10 mins. in a first bath, at 42 DEG  C., containing specified amounts of tin tetrachloride, monosodium phosphate and magnesium chloride, the pH value of this bath being controlled with the aid of apparatus known per se for measuring the pH value.  This apparatus preferably also continuously records the pH value and is associated with a device for actuating an optical or acoustic signal when the limits of the prescribed range of the pH value are reached.  The operator adds magnesium phosphate, ammonium phosphate, alkali phosphates, e.g. disodium phosphate or monosodium phosphate, or phosphoric acid as required to bring the value again within the range.  In some cases it is sufficient to add tin tetrachloride or magnesium chloride to correct the deficiency of these salts in the bath as revealed by chemical analysis.  The silk is then squeezed or subjected to suction and is passed into a second bath at 60 DEG  C. containing ammoniacal disodium phosphate; it is then rinsed, again squeezed or subjected to suction and treatment in the first and second baths is repeated as often as desired; it is then passed through a dilute solution of water-glass and through a weak soap bath, and may, if desired, be subjected to a treatment with an alkaline solution of natural or artificial resins as described in Specification 366,911.  The materials of the various vessels used, of the conveyer cloth, of the squeezing rollers and of the pumps may be as described in Specification 366,911.

Title: Fuel injection systems for internal combustion engines
IPC: F02D41/34
Filed: 1975-06-20
Abstract: 1517953 Fuel injection systems; fuel injection pumps PHYSICS INTERNATIONAL CO 20 June 1975 [21 June 1974] 26420/75 Headings F1A and F1B [Also in Divisions G2-3] The valve of an injector 206, Figs. 5 and 6 is biased open by the pressure of fuel beneath a plunger 228, which is supplied by a gear feedpump (14), Fig. 1 (not shown), via a cylinder 100, Fig. 3, containing a measuring shuttle 102, and biased closed by fuel from a pump, Fig. 2, operated by engine cylinder gas-pressure. The plunger 228 is operated to provide injection pressure when the piston 224 is subject to the closing bias pressure under the control of a timing unit (10), (Fig. 1). The shuttle stroke is controlled by wedge tines 160, 162 positioned by a piston in dependence upon the fuel pressures acting on its opposite sides. The pressure below the piston is controlled by a Piezo-electric valve 180 which opens a pressure relief flow-path 174, 176 in response to a control signal proportional to the difference between a signal from a wedge position sensor (182), Fig. 4 (not shown), and a control signal determined by an operator control as modified by engine speed and temperature, ambient temperature and pressure and programmes for fuel vs speed and speed governing. The control signal from an amplifier (243), Fig. 8 (not shown), passes via a modulator (245), a flyback pulse transformer (246) and a diode (248) to the valve 180. The control signal also controls a Piezo-electric pump 190 which times pressure application to the piston 224. In the main and pilot injection system shown a pilot signal fed to the element 192 operates the plunger 194 to displace sufficient fuel to operate the valve plunger 203 to open the valve 208. Fuel under pressure from the accumulator 200 moves the piston 222 to provide limited injection by the piston 224. A main signal fed to the pump 190 causes opening of the valve 212 and the remaining portion of the stroke of the piston 224. In a system without pilot injection, Fig. 7 (not shown), the chamber above the injection piston is connected to a pressure relief path by a valve (212A) when the pump 190 is not energized. The wedge position sensor may be an electromagnetic Hall effect sensor, a linear variable differential transformer or an inductive sensor.
