Title: Improvements in horse rakes
IPC: A01D76/00
Filed: 1927-01-20
Abstract: 275,488. Bamford, J., and Bamford, C. J. Jan. 20, 1927. Rakes, horse.-Positive means are provided for forcing back to normal operative position the swinging frame carrying the tines of a horse rake in which the rake teeth are mounted on a bar carried by a swinging frame arranged transversely of the machine and pivotally mounted on the axles so that it can be swung upwards by manually operable means or by pawls and ratchets or the like on the wheels when it is desired to raise the rake from the ground. An arm 7 is pivoted to the draught frame 1 and connected by the usual curved link 6 to a pivot 8 on the swing- ing frame to retain the swinging frame in position after the tines have been lowered. A foot or hand lever 9 is pivoted in a clip 11 on the draught frame and is connected by a link 13 to a bracket 14 on the swinging frame. When the tines are lifted the foot lever moves towards the operator, and if on release of the tines they fail to complete their downward movement the driver presses the lever 9 with his foot, thus forcing over the swinging frame. In a modification the link 13 is slotted and connected to a second arm projecting from the lever 7. The swinging frame is thus forced into position through the link 6. A stop is provided to limit the downward movement of the tines.

Title: Improvements in or relating to means for the utilization of heat in bakers' and like ovens
IPC: A21B1/40
Filed: 1936-01-18
Abstract: 468,396. Bakers' ovens. CROZIER, W. H. Jan. 18, 1936, No. 1684. [Class 51 (ii)] In a baker's oven having at the base a single combustion chamber 34 which supplies hot gases to two flue systems serving the right and left-hand halves of the oven and terminating in a common damper-controlled outlet 21, each flue system comprises a primary section consisting of the space between the oven side wall 12 or 14 and the baking chambers 31 and superposed inwardly and outwardly directed tapering flues 24, 25, the primary section delivering to a secondary section formed by an upper curved header 27, a plurality of narrow passages 16 disposed in the side wall contiguous to the inner lining 18, and a bottom header 17. The two headers 17 increase in cross-section towards the rear of the oven where they communicate with a single back flue 19 leading to the outlet 21. The flue systems are divided at the top by a barrier 22 having semi-cylindrical cavities in its side faces, while the plates 23 separating the flues 24, 25 carry parallel fins which sub-divide these flues into a number of narrow passages. The gas flow through each flue system is controlled by an adjustable diaphragm 28 located at the junction of the primary and secondary sections. The sole plates of the baking chambers 31 are formed as jackets 33 through which a portion of the ascending gases, determined by the setting of dampers 37, may pass. The jackets 33 are fitted with a fixed apertured baffle 40, Fig. 3, to which are pivoted two plates 39, the latter being adjustable so that the relative proportions of the gases traversing the front and rear portions of the jackets may be varied.

Abstract: 994,620. Strap fastenings; stud and socket fastenings. E. SCHUMM. Jan. 15, 1964 [Jan. 23, 1963], No. 1726/64. Addition to 943,433 and as improved upon or modified by 948,900. Headings E2A and E2B. A tie formed of resilient flexible material, e.g. synthetic plastics material or rubber, comprises a strip-like portion 1 and a wider portion 2 at one end of the strip-like portion, the portion 2 having an open-sided groove 3 of T-shaped cross-section such that for fastening the tie the strip-like portion 1 can be drawn through the groove and is held in the wider part of the groove when the tie is in use, and for loosening the tie the strip-like portion 1 can be pulled laterally out of the groove, with teeth 10 provided in a row on one side of the strip-like portion and teeth 101 provided in a row on the bottom of the groove, the arrangement being such that when the tie is fastened some of the teeth 10 engage some of the teeth 10<SP>1</SP>, and is characterised in that the strip-like portion is provided with a handling part 14 having an aperture into which the wider portion 2 is pushed so that the handling part extends across the strip-like portion at the ends of the groove 3 and provides additional security against inadvertent pulling of the strip-like portion out of the groove when the tie is in the fastened position. In the embodiments shown the handling part is a ring 14 which is held in position around the part 2 by beads 6 and 7 when the tie is fastened. A wire 16, Fig. 4, and lead seal 17 are fastened through a bore 18 in the part 2 to prevent unauthorised removal of the ring 14. In a second embodiment, Fig. 7, straps 20 carrying plugs 19 are formed on the ring 14, and when the latter is in position around the part 2 the plugs 19 are pushed into holes 23 in the part 2 and retained therein by interengaging shoulders 21, 22. Removal of the ring is thus only possible by cutting the straps 20.

Patent GB-351572-A (GB)
Title: Improvements in light signals and in and relating to light signal systems
IPC: G08G1/095
Filed: 1930-11-17
Abstract: 351,572. Signal lamps. BRITISH POWER RAILWAY SIGNAL CO., Ltd., GLENN, S. L., and PIERCE, E. E., Windsor Works, Slough. Nov. 17, 1930, No. 1781. [Class 75 (iv).] Relates to signalling apparatus producing coloured beams of light for the control of road traffic, and is applicable also to railway signalling, airport and marine signalling, and code signalling. Around a single source of light 52 rotates or oscillates a turret 8 carrying eight glass plates 31 .. 38 of appropriate colours, alternate glasses being screened while the remaining glasses transmit beams through the double lens systems 130, 9 in a fixed housing 7. A hinged lid 57 renders the multi-filament lamp 52 easily accessible. The glasses 31, 33, 35, 37 are amber, 32, 36 red, and 34, 38 green, so that oscillation of the turret forty-five degrees to either side of the position shown in Fig. 4 gives the desired signals for traffic control. This oscillation is effected by an electric motor 21, the signal being automatically returned to the amber position by a mechanical device comprising a disc 60 on the motor shaft 20. As soon as the motor is deenergized a weighted arm 63 or 64 bearing on a roller 61 or 62 on the disc 60 restores the signal to amber. Other devices may be used for this purpose, for example, cams and counterweights, torsion springs, magnets, or air or liquid siphons. A flywheel 71 is frictionally mounted on the shaft 20. The turret 8 may be arranged to rotate unidirectionally by steps to give the necessary indications. The motor shaft may be damped by notching the surface of the armature along its axis and correspondingly notching the surface of the field poles. The armature may also have a damping winding of known form. Direct manual control may be provided for by a handle 72 and a clutch device 78, another clutch 85, releasable by a handle 82, being provided to hold the handle 72 in the engaged position after it has been forced in. Instead of an instantaneous change of colour, there may be a two-colour beam shown for an intervening period. An independent quadruplex aspect for giving the amber signal alone may be mounted above the signal unit in the same housing. In place of a single quadruplex signal, simplified units each with one clear double lens system only may be used at each street of the crossing. In a modification the turret has coloured sectors arranged vertically, the turret being moved up and down to bring the desired coloured screen to the focus of the lensing system.

Filed: 1953-01-21
Abstract: 738,408. Shuttle stop-motions for looms. CRAIG & CO., Ltd., A. F. Dec. 31, 1953 [Jan. 21, 1953], No. 1783/53. Class 142(2). When a shuttle fails to box, a member 54 is not moved by the swell and the driving motor is detached, a brake applied, and springs compressed to check the loom. Failure of the shuttle to box, causes a pawl 53 to remain in a lower position and to engage a shoulder on a boss 32 on an arm 31 connected by members 27, 30 to a trigger 25 and thereby release the handle 18. Release of the handle operates an air valve to remove the air supply from a clutch and admit air to a pneumatically controlled brake. Immediately after the pawl has engaged the shoulder on the boss 32, the pawl, and a second pawl at the other side of the loom, each simultaneously engage shoulders on bosses on arms 35 and partly rotate the arms whereby springs 39 are compressed and, acting as shock absorbers, check the loom. When the rod 18 is moved to the " on " position, the trigger 25 is automatically reset.

Abstract: 164,066. Marks, E. C. R., (Northern Equipment Co.). Jan. 20, 1920. Feed-water, supplying and controlling. - In boiler feed-water systems, means are provided for varying the amount of opening of the feedwater valve together with means for maintaining a constant difference in pressure between the opposite sides of the valve. The feed-water valve 14, Fig. 1, is regulated by known apparatus dependent on the water level in the boiler, the valve-operating lever 15 co-operating with a scale 32 to indicate the flow. Opposite sides of the valve 14 are connected by a duct 24, Fig. 3, and a pipe 22 to chambers 21, 23 on opposite sides of a diaphragm 20, acted on by an adjustable spring 25 and connected to the spindle of a valve 17. The valve 17 is therefore actuated to maintain a constant fall of pressure through the valve 14. In a modification, the valve 17 is controlled by a piston acted on by adjustably weighted lever and by the pressure on the opposite sides of the valve 14. The water may be supplied by a pump delivering at constant pressure.

Title: Improvements in or relating to the treatment of leather and skins
IPC: C14C3/08
Filed: 1964-01-16
Abstract: In a process for softening, fulling and/or tanning leather, e.g. in the form of chrome-tanned cow hide or unhaired lamb or sheep skin, the leather, e.g. after having been rinsed in water, is treated, e.g. in a rotating tanning vat, with an aqueous medium comprising at least one compound having the general formula <FORM:1048321/C6-C7/1> in which A represents an ethylene or propylene radical, B represents an oxyethylene or oxypropylene radical, J represents an alkyl or alkenyl radical having 4 to 22, preferably 8 to 18, carbon atoms, D represents H, acyl, acenyl, R-CONH-C2H4- or R-NH-COE represents -O-CH2-CHOH-CH2-, -O-CH2- CO- or -O-C2H4-, x and y represent one or a higher integer, and z is zero or an integer.  The compounds may be in the form of a salt formed with an inorganic or organic acid, such as formic, acetic or lactic acid, or in the form of a condensate obtained by thermal condensation of the original compounds or their salts.  Before of after the aforementioned treatment, the leather may be treated with an acid dyestuff, e.g. in the presence of an anion-active auxiliary band on a naphthalene-sulphonic acid condensation product, or with an anion-active synthetic full-tanning agent.  During the treatment, powdered mimosa extract or a sulphated neatsfoot or sperm oil may be added to the aqueous medium.  The treated leather may be horsed, sammied, dried, as by being pasted on glass sheets, and buffed.  The resulting soft, e.g. white and glac<\>ae-like, leather may be used for shoe uppers.

Title: Elevator-system controls
IPC: B66B1/18
Filed: 1968-01-15
Abstract: 1,208,621. Lift control systems. RELIANCE ELECTRIC & ENG. CO. 15 Jan., 1968 [20 Jan., 1967], No. 2065/68. Heading B8L. In a multicar lift system in which directional hall calls are allotted to individual cars, an artificial call is automatically made from one or more preferred landings (termed "queue calls") so that if a vacant car is available it will park at a preferred floor. This car is then said to be a "queue car", and only one car may be a queue car at any floor. The system generally is as described in Specification 1,163,727, in which hall calls are assigned to the car best able to provide service by a system in which the work load on the car is represented by a voltage analogue which is compared with a ramp voltage. The artificial "queue call" will thus be assigned to the car best available and on arrival at the preferred floor will become a queue car if it has no other assignment; it then parks with doors open and hall lantern on. Its analogue voltage is biased so that hall calls made at other floors are assigned to the queue car only if all the other cars have an exceptionally heavy work load. A queue car may also be sent to answer any hall call which has remained unanswered for an excessive time. Otherwise a queue car loses its queue status only in response to a car call made by a passenger entering at that floor, or if its M-G set is shut down; this occurs automatically if a car is not used for many minutes, but the queue car is shut down last. More than one floor can be made a "queue floor", and one of them can be given preferance over the others. Any floor may be made a queue floor temporarily if a car serving an actual call at that floor becomes overloaded, as detected by a weighing device, a passenger count, or doors kept open an exceptional time. Thus a second car is assigned to assist the first, which is treated as "out of service" by the allotting equipment. The doors are arranged to stay open longer at floors where both hall and car calls have been made, and except at a queue floor they will reopen for a late passenger. This feature is inhibited at queue floors as otherwise the artificial calls would prevent the doors from closing.

Title: An improved arrangement for locking the control surfaces of a parked flying machine
IPC: B64C13/30
Filed: 1937-01-25
Abstract: 477,194. Locking aircraft - control surfaces. JUNKERS FLUGZEUG - UNDMOTORENWERKE AKT.-GES. Jan. 25, 1937, No. 2169. Convention date, Feb. 29, 1936. [Class 4] An arrangement for locking the control surfaces of parked flying machines comprises a brake arranged to act on the surface itself, or on an adjacent member connected thereto by rigid links or levers, and controlled from the pilot's cockpit. In one form toggle-operated shoe brakes such as shown in Fig. 3, are arranged to act on drums 15 secured to control countershafts in the case of the elevators and ailerons, Fig. 2, and in the case of the rudder secured to the axle of the surface. The brakes are simultaneously applied by a hand lever 32, 33, Fig. 2, through the medium of equalizing levers 28, 29, 51. Lever 32, 33 is adapted to be locked in both " on " and " off " position by a pawl 37 engaging notches formed in a quadrant 36. In a modification fluid links are employed, the hand lever acting directly on the piston of a master cylinder. In a further modification, Fig. 5, pivoted shoe-carrying levers 63, 64, are separated for brakeactuation by toggle links 69, 70 acted on by piston rod 73 of a servocylinder 71 to which pressure fluid is supplied via a pilot-controlled fourway valve and conduits 75, 76 by a pump 77. Links 69, 70 are arranged to pass through the dead centre position and to be held against an abutment 74 by the resilience of levers 63, 64. The brakes can thus be maintained " on " when the four way valve is set to close all the conduits. Fig. 8 shows a device adapted to prevent opening of a throttle control lever 91, beyond the idling position when control surface brake lever 98 is in the " on " position. Movement of lever 91 causes axial movement of a bar 95 adapted to strike or to miss a sector 99 keyed to the shaft of lever 98 should the latter be in the " on " position. According as the latter is in the " on " or " off " position. The control surface brake gear may be interconnected with the wheel brake operating mechanism as shown in Fig. 10, in which operation of control surface brake lever 108 causes actuation of the wheel brakes but when in the " off " position leaves unimpeded the action of wheel brake hand lever 105.
