Title: Improvements in or relating to Safety Locks for Bicycles and the like.
Inventor: VRIES CORNELIS DE
IPC: B62H5/14
Filed: 1916-08-16
Abstract: 102,701. Vries, C. de. Aug. 16, 1916. Locking-apparatus.-In means for locking bicycles &c., wherein a sliding bolt is arranged to engage the wheel or other part, a latch mechanism or lock is provided at each end of the bolt, so that both mechanisms have to be released before the bolt can be disengaged. The two mechanisms a, b are preferably carried by a single U-shaped member d adapted to be mounted, as by spring connexions, upon the bicycle fork. The bolt c is slotted at 3 to engage a pin 4 within the casing 1 of the mechanism a, and it has two lugs 14, 15 to engage-with the depending rims of disks 5, 6 carried respectively by a collar 7 and the pin 4. The pin is fitted with an arm or hand 11, and the collar with a similar arm 9; and when these arms are set to a predetermined position over a dial 16, openings 12, 13 in the disk rims are in line to allow the belt to be drawn out to be engaged with the lock b on the other side of the wheel, and in the extended position of the bolt one lug 15 is disposed outside the rim of the disk 5 and the other lug 14 is between the two rims. For retaining the two disks in set positions, the arm 11 is adapted to engage with holes in the dial, and the disk 5 is adapted to engage, as at 19, with recesses or projections on the underside of the dial, a spring 17 tending to press the two disks apart. The mechanism b preferably has a single disk 20 controlled by an arm 24 moving over a dial, a spring 25 being provided to prevent accidental movement of the arm; this mechanism may, however, have two disks, or it may be provided with a dummy arm which moves over the dial but does not actuate any of the parts within the casing. The casing of the lock a is slotted at 2 for about a quarter of its circumference, so that when the bolt is disengaged, it can be turned through a right-angle to a position parallel with the fork limb. In this position, it is held against movement by the engagement of a hook portion with a fixed pin within the casing, and, by the action of an annular spring 27 which fits tightly the inside of the casing, moves with the bolt and closes that portion of the slot unoccupied by the bolt. The bracket d may be formed of thin sheets riveted together, the base sheet being arranged to overlap the walls of the two casings, and the next sheet provided with notches for engagement by projections on the inside walls of the casings.

Title: Drive arrangements
IPC: F16H41/30
Filed: 1975-03-13
Abstract: 1487752 I C engine driving gear BRITISH LEYLAND UK Ltd 13 March 1975 [15 March 1974] 11591/74 Heading F1B [Also in Division F2]  A fluid flywheel or fluid torque converter is mounted on the primary output shaft of a power unit and receives high-pressure oil from a forced feed lubrication system of the power unit, the oil supply to both the principal bearings of the unit and the flywheel or converter is through an arterial oilway formed in the length of the output shaft and the oil is returnable from the flywheel or converter to the lubrication system via a pressure relief valve concentrically housed within a hollow end of the output shaft. A reciprocating-piston inline I.C. engine has a directly driven lubricating oil pump mounted at one end of the crank-shaft and the other end of the crank-shaft carries a fluid flywheel or, as shown in Fig. 2, a torque converter. The stator 40 of the converter is fixed to the engine housing, impeller 41 is keyed to the crankshaft and turbine 42 is rotatably mounted on crank-shaft extension 2B and carries a driving gear 44. Oil from the pump passes through passageways 20 in the crank-shaft and part of the oil lubricates the main and big-end bearings; the remainder, as shown by arrows, flows through the converter. Excess pressure in the converter is relieved by a spring-loaded ball valve 46, which allows oil to flow through apertures 48 in a hollow bolt 45 and hence to the engine sump. Bolt 45 also secures the converter on the shaft.

Title: Improvements in and relating to galvanic cells
IPC: H01M4/36
Filed: 1955-04-22
Abstract: 772,038. Batteries. UNION CARBIDE & CARBON CORPORATION. April 22, 1955 [April 30, 1954; April 30, 1954; April 30, 1954], No. 11628/55. Class 53. In order to fix the initial voltage of a primary cell having a consumable metal anode having an electrical potential greater than zinc, particularly magnesium, and to maintain a relatively high voltage level during the final portion of its service, an oxidic depolarizer is used having a surface coating of a lower oxide of the depolarizer. With a manganese dioxide as a depolarizer, the lower oxide at its surface is manganic oxide. One method of obtaining Mn 2 0 3  comprises heating the one of Mn0 2  in a reducing gas, e.g. CH 4 , CO 2 , H or a mixture thereof. The resulting coated ore is then stabilized by the addition of an agent to adjust the pH thereof to obtain the desired initial voltage of the cell. Fig. 1 shows a carbon-magnesium cell having a magnesium bromide electrolyte. The cathode 14 is formed of a carbon rod with a depolarizer mix reduced and stabilized as stated above. Another method of forming the coating of Mn 2 0 3  is to mix the Mn0 2  with a reducing agent, e.g. oxalic acid, formic acid, hydrogen peroxide, or manganous oxide, the pH of the mixture is then adjusted. The pH control may be effected by the use of MgO, NH 4 0H, MgOH or MnO. Another method of forming the lower oxide coating comprises forming a mixture of the oxidic depolarizer ore, e.g. MnO 2  and a water-soluble salt of a polyvalent metal, e.g. Mn, Sr, Fe or Pb. If the anode is aluminium instead of magnesium, the oxidic depolarizer may consist of MnO 2  mixed with manganous phosphate or manganous acetate. In cells having zinc anode, the oxidic depolarizer consists of Mn0 2  mixed with MnCl 2 .

Title: Improvements in thermionic devices
IPC: H01J21/20
Filed: 1919-05-12
Abstract: 149,422. Fleming, J. A. May 12, 1919. Vacuum tubes.-A thermionic valve has two pairs of plates C, D, Fig. 1, arranged symmetrically around and close to a filament cathode B. The plates are of nickel or platinoid and may be in the form of segments of cylinders with the convex surfaces nearest the filament, and at a distance of 2 to 5 millimeters therefrom. The plates and filament may be mounted at one end of the bulb, the leads passing through glass tubes I, or the plates may be supported from the side of the bulb. The valve may be used as a detector &c. in wireless systems, the plates c, acting as " collectors " of the electrons, being connected through a galvanometer or telephone receiver F, Fig. 4, with the positive end of the filament battery E, the other plates D being connected either directly or through an air-core transformer with the closed receiving circuit L. The application of a difference of potential to the plates D causes the current in its circuit of the receiver &c. to be reduced. Two or more such valves may be connected in parallel. In the arrangement shown in Fig. 5, the plates C are connected with a relay M closing the circuit of a call-bell, lamp, recorder such as a Morse inker, or motor O operating a rudder, and the plates D are connected across a high resistance Q in the anode circuit of a 3- electrode valve U connected in a receiving circuit. Two or three such valves may be used for steering &c. a boat or an aeroplane from a distance by employing waves of different length. The arrangement may be employed as a detector in an alternating-current potentiometer or wheatstone bridge. Specification 24850/04 is referred to. According to the Provisional Specification, two of the plates are placed nearer the filament than the other two.
Patent GB-697792-A (GB)
Title: An improved method of and apparatus for carrying out endothermic reactions between solid and gaseous reactants
IPC: C01C3/00
Filed: 1950-05-12
Abstract: <PICT:0697792/III/1> Endothermic reactions between solids and gases yielding solid or liquid products are performed by injecting the solid suspended in the gas through annular nozzle 55 into reaction zone 30 so that the annular stream surrounds a central zone in which a high temperature is maintained by means of an exothermic reaction, e.g. between preheated air introduced at 33 and a gaseous or liquid hydrocarbon entering through nozzles 67.  Heated residual gas from the process may be introduced as a helical stream near the walls of the reaction zone through oblique nozzles 72.  Cold residual gas is fed through nozzle 84 to cause separation of the reaction products, some of which are collected at 87; further separation is effected in chamber 90, which is cooled and may be provided with apparatus 94 for generating ultrasonic vibrations, and in cyclone separators 98, 99. Apparatus is described, Fig. 2 (not shown), for preheating the air and residual gas used in the process by passing them through regenerators which are heated by burning residual gas or fuel gas. Cyanides (e.g. sodium syanide) are produced by reacting a suspension of carbonates (e.g. sodium carbonate) in hydrocarbon gas with nitrogen; elementary carbon or a catalyst, e.g. iron oxide, may be mixed with the carbonate. Reference is also made to producing iron powder or spongy iron by injecting iron ore suspended in a reducing gas.ALSO:Iron powder or spongy iron is produced by injecting axially an annular stream of finely pulverized iron ore suspended in a reducing gas into a reaction chamber so that the annular stream surrounds a central zone in which a high temperature is maintained by means of an exothermic reaction e.g. between preheated air and a gaseous, liquid, or finely divided solid fuel (see Group III).
