Title: Improvements in or relating to pedal cranks for bicycles and the like
IPC: B62M3/00
Filed: 1922-06-23
Abstract: 198,574. Payne, A. E. H. June 23, 1922. Cranks.-In bicycle or like propelling means, a pedal carrying arm E is pivoted on a shorter crank arm or member A fixed to the crank shaft B, the pivotal connection K being adjacent to the crank shaft, so that the pedal carrying arm may rock relatively to the crank arm A between limits provided by studs or shoulders thereon, or by a sleeve-like member H, without appreciably varying the throw. The arrangement enables the arm E and pedal F to advance to the position indicated in broken lines at the top of the stroke when about to commence the downward or driving stroke. At the bottom of the stroke, the device is stated to provide an additional leverage about the crank shaft B. The sleeve H may be secured to the member A by screws J, the opening in the sleeve and the sides I of the member A being inclined to provide a dovetail fitting as shown in Fig. 3.

Title: A blood anticoagulating agent and process for the manufacture thereof
IPC: C08B37/08
Filed: 1952-07-09
Abstract: The invention comprises a blood-anticoagulating agent comprising a polysulphuric acid ester of a hydrolytically degraded chondroitin-sulphuric acid, said ester having a sulphur content of between 11 and 16 per cent. and an intrinsic viscosity of from 0.05 and 0.10, and alkali salts of the same.  They are prepared by hydrolyzing chondroitin-sulphuric acid until a product having an intrinsic viscosity of below 0.25 is obtained, and then converting to a polysulphuric acid, e.g. by treatment with chlorosulphonic acid, sulphur trioxide or oleum in the presence of an organic base such as pyridine, quinoline or a -picoline.  The hydrolyzed material, before or after sulphation, may be subject to fractional precipitation, e.g. by means of acetone, methanol or ethanol.  An example is given in which chondroitin-sulphuric acid is hydrolyzed with hydrochloric acid, esterified with chlorosulphonic acid in the presence of pyridine, and the product purified by precipitating it as the insoluble narcotine salt from which the product is finally recovered by treatment with aqueous sodium carbonate.

Title: Method for fusing borates
IPC: C01B35/12
Filed: 1938-06-15
Abstract: 504,870. Continuous furnaces for chemical manufactures. BEIK, F. A. June 15, 1938, No. 17824. [Class 51 (ii)] [Also in Group III] A fused borate material is obtained by fusing an upper layer of a bed of material including unfused hydrated borates, cooling the fused layer to solidification while it is in contact with an unfused bottom layer of the bed of material which includes partially dehydrated borates, and then separating the upper layer of solidified fused material from the bottom layer of unfused material. Unfused borate material is fed from a hopper 12 on to a revolving table member 11 in the form of an annular bed 13. This bed of material is fed through an arcuate furnace 14 emerging with its upper layer in a fused condition. The rotation of the table carries the fused material through an air stream from a blower 15 which cools and solidifies it and past a scraping device 16 which separates the fused and a portion of the unfused material for delivery to a Trommel screen which completes the separation. The unfused material is returned from the screen to the hopper 12. Burners 35 and 35<1> are provided at the ends of the furnace 14 while the midportion thereof is provided with a stack 33. The discharge orifice 12<1> of the hopper 12 is arranged on a radius of the revolving table. The depth of the bed of material is controlled by the position of the hopper and the angle of repose of the material while a spreader plate 47 is provided, the lower end of which is shaped to form a trough in the top of the bed of material and spread it as the table rotates. The device 16 for separating the fused from the unfused material comprises a serrated forwardly-inclined rake 51. The fused material rides up over the rake and falls into a trough 54 whilst the bed of unfused material passes below the rake. The fused material is removed from the trough by a travelling drag link mechanism 55 and passes on to a travelling conveyer which conducts it to the Trommel screen.

Title: Flexible endoscopic viewing tube
IPC: A61B1/00
Filed: 1927-07-05
Abstract: 296,512. Heimberger, H. July 5, 1927. Optical instruments.-The optical system of a flexible endoscope tube comprises pairs of rectangular prisms b, b<1> mounted in casings a with their short sides normal to the axis of the tube and their hypotenuses parallel to one another. The casings a are formed with obliquely disposed tubular extensions c fitting the one into the other and forming a swivel joint between the optical units. The members c are secured in coacting position by tangential pins d engaging annular recesses in the members. The arrangement is, such that light proceeding axially along the tube enters the prism b, is reflected at the hypotenuse face thereof and then at the longer rectangular face, which is silvered, and finally emerges from the prism normally to the hypotenuse face and in the axis of the swivel joint c. A complementary path is followed through the prism b<1>. The prisms b, b<1> are rigidly connected with adjacent prisms by members m containing the lenses of the system. The tube is covered by a flexible rubber sheath and is provided with a lamp having a protective sheath at its inner end. The optical units may be turned about theirpivots, to conform with the shape of bodily cavities, by cords e passing around the outer members e and led through guides in preceding members to the outer end of the instrument where they may be secured in any desired position. Air may be passed through the space between thesheath and the optical system.

Title: Thermoelectric refrigerator
IPC: F25D11/00
Filed: 1964-04-29
Abstract: 1,056,049. Thermoelectric devices. BORGWARNER CORPORATION. April 29, 1964 [May 17, 1963]. No. 17853/64. Heading H1K In a thermoelectric refrigerator comprising a " freezer " compartment and a " cooler " compartment thermally isolated from one another and cooled by separate Peltier units, a power supply arrangement switchable between two energy levels is provided, the system being arranged so that such switching does not affect the temperature difference produced by the " freezer " compartment Peltier unit. In a first embodiment, Fig. 3 (not shown), all the Peltier units are connected in series and supplied with power from rectifiers 47, 48 fed by transformer 46 the primary winding tappings of which are changed by relay 45 controoled by " cooler " compartment thermostat 51 to provide two rates of cooling for the cooler" compartment. The " freezer " compartment Peltier unit produces maximum temperature difference at a current between the two currents supplied by the system, Fig. 4 (not shown), so that the " freezer " compartment is unaffected by the operation of the thermostat. In a second embodiment, Fig. 5 (not shown), the " cooler " compartment Peltier units are arranged in two groups connected either in series or in parallel by auxiliary contacts of the relay 85 which changes the primary winding taps of the transformer. The system is such that the total impedance of the Peltier units is selected according to the voltage level so that the total current is maintained constant, and hence the " freezer " compartment Peltier unit, which carries the total current, is unaffected by the switching. Since the " cooler " compartment Peltier units are arranged to have peak efficiency at the total current level, when they are connected in parallel their efficiency is decreased and the temperature difference generated is reduced. In a modification of the second embodiment, Fig. 6 (not shown), the " freezer " compartment Peltier units are arranged for switching in series and parallel and the " cooler " compartment Peltier units carry the total current. The system is arranged so that the current through each " freezer " compartment Peltier unit is constant for both voltage conditions, the total current varying to produce the desired control of the " cooler " compartment Peltier units. As shown, Fig. 1, the Peltier elements 32 are mounted between tapered heat-conducting members 31, 33 on which are mounted cold plate 30 and cooling fins 34 respectively. The unit shown is for the " freezer " compartment, and four similar units are provided for the main " cooler " compartment and are mounted with their fins protruding from the back of the cabinet.

Title: Improvements in or relating to automatic control of electro-static precipitators
Inventor: RODGER JAMES

Filed: 1955-06-21
Abstract: 769,880. Protective arrangements; control systems for electrostatic precipitators. HOWDEN & CO., Ltd., J. June 21, 1955, No. 17878/55. Class 38 (4). A valve V responsive to flash-over conditions in a precipitator P, supplied, from. a source 11-13 through saturable reactors S1-S3 and rectifier 10, controls, through a magnetic amplifier 20-22 and rectifier 17, the flow of direct current in the control windings 24-26 of the reactors, the arrangement being such that upon flash-over the impedance of the reactors is increased and the flash-over consequently extinguished. The valve, in series with the control winding of the amplifier, receives its anode voltage from a shunt resistor R4 carrying the discharge current of the precipitator, conduction of the valve being normally prevented, however, by grid bias obtained from a potential divider R1, R2 which shunts the precipitator. The amplifier is in a low impedance condition, due to biasing current supplied from an external source A, A<SP>1</SP> to the windings 20, so that a large saturating current traverses the control windings of the reactors S1-S3. Upon occurrence of flash-over the grid bias on valve V falls and the anode voltage increases, so that the valve now conducts and energizes the control windings of the amplifier-annulling the effect of windings 20 and thus causing the amplifier to assume a condition of high impedance. The resulting de-saturation of reactors S1-S3 reduces the output voltage of rectifier 10 and so extinguishes the flash-over. Absence of current flow through R4 returns valve V to a non-conducting state and normal supply conditions are restored.

Abstract: 1,106,381. Hydraulic intensifiers. KEELAVITE HYDRAULICS Ltd. Jan. 6, 1965 [Oct. 6, 1963], No.17887/63. Heading F1P. An apparatus for testing a hydraulic system (not shown) by subjecting the system to liquid pressure in accordance with a predetermined cycle, comprises a pressure intensifier 21 having a high-pressure piston 30 movable in a chamber 31 connected to the hydraulic system and integral with at least two further pistons 26, 22 the faces 24, 28 of which, on initiation of a cycle, are arranged to be selectively pressurized from a source or sources of hydraulic fluid such as to cause the high-pressure piston to apply pressure to the system in accordance with the predetermined cycle. To initiate the cycle a solenoid operated valve 1, Fig. 2 (not shown) is energized whereupon the large piston face 24 of the intensifier is pressurized by a pump 5 via a line 8, the pressure of fluid supplied by the pump being controlled by a relief valve 10. The intensifier piston 30 therefore applies peak pressure to the hydraulic system. The pressure acting on the face 24 is communicated through a line 84 to operate a shuttle valve 2 which causes the pressurization of the intermediate piston face 28 from a line 16, itself pressurized from the main line 8 through a reducing valve 17. The pressure applied by the piston 30 consequently decreases and a timer or a pressure operated valve is arranged to de-energize the solenoid valve 1 to complete the cycle.
