Title: Improvements in and relating to mechanical starting devices for internal combustion engines
IPC: F02N3/02
Filed: 1921-12-14
Abstract: 194,772. Brennan, L. Dec. 14, 1921. Turning-gear.-A starting-device for aeroplane or other engines is permanently associated with the engine and its supporting structure and comprises one or more india-rubber, metal, or like spring elements which can be extended one at a time or collectively and then released collectively to start the engine. India-rubber cords 26 are stretched by hand and then detachably .secured at their to hooks or supports 33. They may, however, be stretched collectively by turning the propeller. The cords 26 are arranged in groups, each secured to a wire cable 24 or a chain passing over a pulley 55 and wound on a pulley 6 rotatable on the propeller hub or shaft or an enginedriven shalt, or on the crank-case of a revolving- cvlinder engine. A ratchet-wheel 10 fast to the pulley 6 is engaged by spring-controlled pawls 21 on the propeller hub &c., the pawls being disengaged by centrifugal action when the engine is running. On a second pulley 7 fast to the pulley 6 are wound cords 53 connected to light springs, which re-wind the cables 24 when the springs 26 are released from the supports 33. In order to balance the pulleys 6, 7, each has a single groove in which are wound several cords 24 or 53, and the cords leave the pulleys in different tangential directions. While the springs are being stretched. an arm on the pulleys is engaged by a wedgeshaped sliding stop. At starting, the stop is withdrawn by means of a chain 45 connected to a handle near the pilot's seat, or by a pinion engaging a rack on the stop, or by bell-cranks and rods. Instead of a sliding stop, a wedge-shaped or other rotatable cam may be employed. If the engine starts backwards, the springs are re-stretched and give a second starting-impulse.

Filed: 1956-11-05
Abstract: 796,216. Air and gas heaters. AIR PREHEATER CORPORATION. Nov. 5, 1956 [Dec. 19, 1955], No. 33654/56. Class 64(1) Pellets 29 move downwardly first through an ascending stream of hot gas and then through an ascending stream of cooler gas and are impelled by gravity over slightly inclined screens 25, 27. Gas flows from the inlet 22 through the screens 25 to the outlet 24 of a chamber 10 and heats the pebbles which then give up heat to air flowing through a chamber 12 and the screens 27. The screens 25, 27 are connected by a conveyer 16 and by director vanes 44 and are vibrated either parallel to or transversely of the direction of pellet flow. Restricted duct sections 14, 26 and 34 retard pellet flow to prevent excessive fluid leakage from the chambers 10, 12. Modified constructions are described in which the screens are either alternately inclined from a point midway between the sides of the chambers or are alternately inclined from the opposite sides of the chambers.

Filed: 1929-11-07
Abstract: 336,829. Glascodine, R. T., Whitmore, R. L., and Spencer Moulton & Co., Ltd., G. Nov. 7, 1929. Combined buffer and draw-gear.-In a central buffing and draw-gear for railway vehicles of the kind in which a friction gear and simultaneously acting springs are carried by a casing surrounded by a draw-bar yoke, the friction gear 3 is disposed at one end of the casing, while the springs are arranged tandem-wise within the casing 1 so as to operate independently of the friction gear, preferably being so associated with compression and abutment plates that they are compressed either first in series and then in parallel or in parallel throughout the stroke. In the construction shown in Fig. 1 two springs 7, 10 of the compound rubber and metal type separated by a sleeved abutment plate 8 are associated with compression plates 6, 9, the plate 9 having a central boss 15 adapted to coact with an extension 14 of a bolt 13 holding the wedges 2 of the friction gear. In operation, e.g. in buffing, the springs 7, 10 are compressed in series until the sleeve 17 abuts against the end wall 11 of the casing 1, then the spring 7 is compressed alone until the elements 14, 15 contact, and finally the springs 7, 10 are compressed in parallel. If the sleeve 17 were designed to abut initially against the wall 11, the series stage of compression would be omitted; while, if the elements 14, 15 were originally in contact, compression of the spring 7 alone would not occur. In a modification, three springs are used in co-operation with two sleeved abutment plates and three compression plates.

Title: Ink drop printing apparatus and method
IPC: B41J2/12
Filed: 1973-07-18
Abstract: 1444602 Printers SHARP KK 18 July 1973 34245/73 Heading G4H An ink-drop printer using deflection in an electric field of electrically-charged ink drops, comprises means for modifying the charge on a charged drop when that drop is not to travel in the wake of a charged preceding drop, to compensate for air resistance. Each character is built up as a matrix of dots, charging being under control of pulses from a read-only-memory character generator which are modulated with a ramp voltage and subjected to gain control before being used to control charging. The pulse stream from the character generator is also fed via a delay and flip-flop to control the gain control so that a pulse not immediately preceded by another pulse is reduced in amplitude before being used to control charging. Sync. signals controlling production of ink drops also clock the delay and flip-flop and via a counter control the read-only-memory and ramp modulation. The output of the flip-flop is a series of variableduration pulses. These may be integrated before being used in the gain control. In order to reduce the electrostatic effects of drops on each other, alternate drops may be always uncharged, in which case a counter as well as the delay is used in control of the flip-flop.

Title: Improvements relating to the detection of fuel element sheathing failures in nuclear reactors
Inventor: MCKNIGHT JAMES ALAN
IPC: G21C17/025
Filed: 1964-08-21
Abstract: 1,108,137. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 12 Aug., 1965 [21 Aug., 1964; 8 March, 1965; 21 June, 1965], Nos. 34387/64, 9699/65 and 26218/65. Heading G6C. In a liquid cooled reactor, gaseous fission products, which escape into the coolant through a fuel element sheathing failure, are collected in zones, within the coolant near each element assembly. The presence of gas in the specified zones is detected by electrical, thermal, or sonic devices and is an indication of sheathing failure at the element assembly where gas is accumulated. The coolant flows vertically through each assembly and a vortex action may be induced by fixed vanes. This directs the fluid to the peripheral walls of the device by centrifugal action and thus urges gas bubbles into the central axial region. The collection of the gas at the axial region may be effected by a fixed collector bell or by a drum which may be rotated to reduce the effect of static boundary layer effects. In a further embodiment, fission gases collected under normal conditions in a particular zone within the coolant are swept away by coolant in the event of a sheath fracture. Detection of this event indicates the element failure.

Title: Manufacture of artificial filaments of lobed cross-section
IPC: D01D5/253
Filed: 1959-10-14
Abstract: Artificial filaments having grooves extending throughout their lengths so that the cross-section of a filament at any point exhibits five pronounced lobes circumferentially spaced apart from each other by the grooves are produced by dry spinning a solution of a filament-forming material in a volatile solvent through one or more pentagonal spinning orifices which may be regular pentagons.  The solution may be dry spun through a spinneret in which only some of the spinning orifices are pentagonal.  The filament-forming material may be a cellulose acetate, e.g. a secondary cellulose acetate dissolved in acetone.  In an example, a tow of yarns consisting of dry spun secondary cellulose acetate filaments produced according to the invention is crimped in a stuffing box crimper to impart an average of about 8 crimps per inch of tensioned tow, the tow opened in conventional manner, sprayed with 8% of its weight of glycerin triacetate as plasticizer, and formed into a filter rod having a denier of 86,000.  The rod is cured at room temperature for 2 hours to cause adhesion of the filaments at their points of contact, and cut into 15 mm. filter plugs.ALSO:Tobacco-smoke filters are produced from a tow of yarns consisting of dry spun cellulose acetate filaments to impart an average of about 8 crimps per inch of tensioned tow.

Abstract: 776,685. Textile ring spinning machine drives. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 8, 1955 [Dec. 1, 1954], No. 34825/54. Class 120 (2). [Also in Group XXXVII] In an electrically driven textile ring spinning, doubling or like machine means are provided to interrupt the drive of the machine at a predetermined instant during the winding of a layer on a bobbin and to re-establish the drive at some convenient time before the beginning of the next layer built up in the same direction, the machine being allowed to coast in the period between the interruption and the reestablishment of the drive. In the arrangement shown a micro switch 10 is connected in circuit with the motor driving the machine in such a manner as to control the interruption and re-establishment of the drive in accordance with the invention. The switch is actuated by a cam consisting of two annular cam discs 4 which are annularly adjustable on a support 3 by means of bolts 5 passing through arcuate slots 6 in the cam discs. Each disc is formed with portions 7 of increased radius alternating with portions 7<SP>1</SP> of reduced radius, the portions 7 overlapping to an extent which can be varied by loosening the bolts 5 and adjusting the discs angularly with respect to each other. The effective peripheral length of the portions 7 and 7<SP>1</SP> can thus be adjusted and the angular position of these portions relative to the shaft 1 can also be adjusted. The cam support 3 is mounted on the shaft 1 which also carries the operating cam of the building motion lever for the machine. Thus the operation of the switch can be adjusted with respect to the building motion. The switch 10 is carried in a bracket 8 free to swing on the spigot 9 of the cam support 3 and the position of the bracket 8 and thus the switch 10 relatively to the cam support 3 can be finely adjusted by screws 15 and lugs 13. Operation of the switch by the cam is through a roller 19 carried at the end of a pivoted arm 18 which is in contact with the operating member 10<SP>1</SP> of the switch 10. The form of the cam discs 4 and the number of portions 7 and 7<SP>1</SP> of different radius are chosen to suit the particular requirements and the type of package being built. Various ways of connecting the switch in circuit with the driving means of the machine whether it be a single speed driving motor, an electromagnetic clutch for coupling the driving motor to the machine, or a relay controlling the energization of such a clutch are shown by wiring diagrams. Diagrams are also shown for incorporating the switch in machines having both high speed and low speed motors. Specifications 716,705 and 716,715 are referred to.

Abstract: 501,682. Dried blood preparations. AKTIESELSKABET NIRO. ATOMIZER. Dec. 17, 1937, No. 34990. Convention date, Dec. 23, 1936. [Class 49] In treating and drying blood to form a water-soluble powder, the blood or the portion of blood containing fibrin and corpuscles is, before drying, rendered homogeneous by highly comminuting, e.g. in a homogenizer or a,colloid mill, in such manner that the corpuscles are broken down. The drying is preferably effected by atomizing into a current of hot gas. In one form, the blood is allowed to clot and, after removing the serum, the clot consisting of fibrin red corpuscles and a little serum is highly comminuted and dried. In another form, the fibrin is removed and the residue separated into light and dark albumen, e.g. by centrifuging, the fibrin is added to the dark albumen which contains the corpuscles and the product is made homogeneous and dried with or without addition of the light albumen.
