Abstract: 724,560. Gearing for stopping and starting machinery; controlling reverse gearing. ROAD MACHINES (DRAYTON), Ltd., and ROBB, W. M. Feb. 28, 1953, No. 5666/53. Class 80 (2) [Also in Groups XXX, XXXI and XXXIV]. In a power driven vehicle for use upon a monorail system, a gear box comprises in combination a positively driven clutch drum 17, a forward drive clutch disc 25 on one side of the drum and 'a reverse drive clutch disc 22 on the other, manually operable means such as a handle 36 &c. for moving the drum axially into driving engagement with either of the clutch discs, the drum being biased towards its neutral position, spring loaded catch mechanism such as a lever 50 and detent 46, 49 for retaining the drum in driving engagement with either of the discs and means, such as a shoe 55, operable by a 'stop (not shown) adjustably positioned on the rail for releasing the catch mechanism. The disc 22 is connected to a sprocket 23 which, through a chain 29 Fig. 5, passing over an idle sprocket 30, rotates a sprocket 27 on a driven shaft 28 in the reverse direction, and the disc 25 is connected to a sprocket 26 rotating the driven shaft forwardly through a chain 34 and sprocket 33; the drum 17 on a shaft 18 is driven through multiple belts 16 and a shaft 14 rotated by the motor on the vehicle, and the gear box driven shaft 28 is drivingly connected to a bogie rail-wheel by a chain 10 &c. The lever 36 is mounted on a spindle 37 passing through the box, and carries an arm 38 and rod 39, the latter passing through a hole in and carrying springs 42 abutting a double-armed rocker member 40 so that movement of the lever rocks the rocker member, which is connected to the shaft 18 for corresponding axial movement of the latter to engage either the forward or reverse drive clutch; the lever 36, clutch drum 17 &c. are biased to the neutral position by springs 44. The spindle 37 carries at its far end a catch plate 46, either side 47, 48 of which is engageable by a projection 49 on a hand-lever 50 pivoted at 51 and urged to the left of Fig. 5 by a spring 52 to retain either the forward or reverse gear in engagement, the other end of the hand-lever being connected by a rod 54 to the shoe 55, the projection 49 being disengaged from the catch plate when the shoe contacts the stop on the monorail and the engaged clutch accordingly disengaged. The shaft 37 also carries a cam 57 which bears against the free end of a brake shoe 58 pivoted at 59 to the gear box and urged by a spring 60 into engagement with a brake drum 61 on one end of the driven shaft 28, the arrangement being such that when the lever 36 is in either the forward or reverse position the brake is disengaged, but the brake is applied when the lever is in the neutral position. The drive clutches can be disengaged manually at any time by operation of the lever 50. Specifications 720,680, [Group XXX], and 720,681, [Group XXXII], are referred to.

Title: Improvements in and relating to concrete linings for shafts, wells and other shaft-like structures
IPC: E21D5/04
Filed: 1926-03-02
Abstract: 270,041. Blandford, T., and Gee, A. March 2, 1926. Shafts and wells.-A concrete lining for shafts, wells, and other shaft-like structures comprises a body of concrete cast in situ in contact with a back sheeting adjacent the ground and reinforcements, wholly embedded in the concrete, spaced from the back sheeting and unconnected thereto. The reinforcement may be arranged only in the half or third of the thickness of the concrete remote from the back sheeting. As excavation proceeds, corrugated iron sheets 1 are placed against the ground and held by iron rings 3 and wedges 4, lower rings 3 being supported from upper rings by hooks 5. After a desired depth is reached, a water garland 6 is built round the bottom of the sheeting 1, the garland comprising a wooden ring carrying a vertical iron ring; pipes 7 remove the water from the garland'. A wedge 8 is then cut out of the ground and a timber packing 9 laid on the shaft bottom. A steel base ring 10 is laid on the packing 9 and vertical angle irons 12 are placed in pockets in the ring 10, aligned angle irons 12 being connected by fish plates. Circumferential reinforcements 13 are threaded through apertures in the angle irons 12 and their ends are connected by a wired lap joint. Bars 18 on the rings 3, clamps 17 bolted to the angle irons 12 and engaging the bars 18, and lacing bars 19, secured to the bars 18, form temporary supports for the reinforcements 12, 13. Shuttering 16 is then built on the base ring 10 which is further provided with a footing of sand. Concrete is then filled in up to the garland 6, and after this concrete has set, broken brick covered with thick cement is filled in between the garland 6 and the corrugated sheeting 1. Further shuttering 16 is then erected and concreting continued in desired steps, the rings 3. wedges 4, bars 18, clamps 17, and lacing bars 19 being removed as the concreting is effected. On reaching the bottom of the previously finished portion of the lining, overlapping shuttering is provided to make the joint, and one or more pipes are passed through the shuttering and sheeting at 1 at this part; concreting is then completed and when the concrete has set, liquid cement is forced through the pipes 7 till all flow of water through the upper pipes has ceased ; after further setting, further cement may be injected at high pressure and the pipe 7 temporarily sealed. A further length of shaft is then excavated and lined, angle irons 12 of adjacent lengths being connected by fish plates. At intervals, permanent garlands 20 are provided, the shaft being widened at these points to give a uniform thickness of lining.

Patent GB-909616-A (GB)
Title: Improvements relating to compressed fluid braking apparatus
Inventor: SIMMONS ARTHUR WILLIAM
IPC: B60T15/30
Filed: 1960-02-22
Abstract: 909,616. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. Feb. 22, 1961 [Feb. 22, 1960], No. 6096/60. Class 103 (1). In a triple valve where communication of a brake cylinder with a source of compressed fluid provided by an auxiliary reservoir is controlled by an application valve 20 operable by a diaphragm 12 subject on one side 15 to auxiliary reservoir pressure and on the other side 13 to brake pipe pressure, the effective area of the diaphragm subject to auxiliary reservoir pressure is less than that subject to brake pipe pressure by an amount which, in the released condition, is exposed to atmospheric pressure but which is exposed to a pressure more nearly equal the auxiliary reservoir pressure by valve means actuated by the diaphragm in its travel between the release and commencement of application positions. With the diaphragm 12 and follower 17 in the normal release position to which they are biased by the greater area of side 13, subject to brake pipe pressure from duct 14, and the lesser area of side 15, subject to auxiliary reservoir pressure from duct 16, due to the area of the thick-walled stem 28 subject to atmospheric pressure in chamber 30 through duct 34, the follower holds the reservoir charging valve 18 and brake cylinder release valve 22 open and application valve 20 shut. A bleed passage 25 between the brake pipe and the auxiliary reservoir is also open in this condition. On reduction in brake pipe pressure to apply the brakes, the diaphragm moves upwards closing first valve 18 then valve 22. A closure member 35, mounted on spring- biased diaphragm 36, seals off the chamber 30, connected to the quick service volume 31, from atmosphere and the end of the hollow stem 28 leaves the member 35 to allow connection between the quick-service volume 31 and brake pipe pressure in chamber 14, thus subjecting the area of the thick stem 28 to brake pipe pressure. With upward movement of the follower 17 the application valve 20 is opened. As pressure in the auxiliary reservoir approaches brake pipe pressure the diaphragm begins to move downwards to the lap position until the valve 20 is closed. Since the underside of the diaphragm 36 is subject to quick service pressure through passage 32a, and is opposed only by atmospheric pressure over its major top area, there is a pressure differential maintaining the closure member 35 against the outer annular seat, forming a quick service exhaust valve. Since this exhaust valve has to be opened by movement of the diaphragm 17 from lap to release position, a resistance is thus provided to this movement to provide lap stability. Specification 846,314 is referred to.

Title: Improvements in or relating to frequency modulators
IPC: H03C3/09
Filed: 1967-02-08
Abstract: 1,105,340. Automatic frequency control systems. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 8 Feb., 1967 [25 Feb., 1966], No. 6107/67. Heading H3A. A tunable oscillator 1 is frequency modulated by means of an automatic phase control loop which locks its frequency with reference to that of a frequency-modulated reference oscillator 5; the frequency deviation is then independent of the tuning of the oscillator. In Fig. 1 the output of the reference oscillator 5 is frequencymodulated by the input at terminal 11 to modulator 12, and is fed to a mixer 4 together with the output of oscillator 1. The lower sideband is selected by filter 6, reduced in frequency by a frequency divider 7, and compared with a second reference oscillator 8 in a phase comparator 10 which controls the frequency of the oscillator 1. The centre frequency of the oscillator 1 can be adjusted by a tuning knob 2 which is ganged to a control of the division ratio of divider 7. In a modification, Fig. 2 (not shown), for use where the oscillator 1 is to be tuned to one of a number of frequencies spaced apart by the same frequency interval F q , the divider 7 is replaced by a mixer (13) supplied with harmonics of a stable reference oscillator (14) operating at the frequency Fq; this oscillator also replaces oscillator 5 and 8 by supplying the required frequencies through known frequency converter circuits (16 and 17). In a further modification, Fig. 3 (not shown), the output of filter 6 provides one input to phase discriminator 10, the other input being supplied with harmonics of a reference oscillator (18) operating at frequency Fq; again the reference oscillator (18) replaces the oscillator 5.
Patent GB-416005-A (GB)
Title: Improvements in or relating to the cementing together of pieces of stock
IPC: C09J5/00
Filed: 1933-03-01
Abstract: An adhesive for securing together pieces of stock, e.g. shoe soles to uppers, comprises a dissolved cellulose derivative of such a nature, as evidenced by a low viscosity characteristic when in the dissolved state, that it is adapted rapidly to penetrate into the piece of stock to form an anchorage thereto, and a cellulose derivative of such a nature, as evidenced by a higher viscosity characteristic, that it is not adapted to penetrate into the piece of stock to such a degree but is adapted to remain to a greater extent upon the surface. When the cellulose derivatives are nitrocelluloses, the former should have a viscosity characteristic of less than about 4 seconds and the latter of more than about 10 seconds on the scale described in the "Bulletin of the American Society for Testing Materials," 1929, pp. 647-8.  In an example, the adhesive comprises two nitrocelluloses of about 12 per cent nitrogen content of the type known as soluble pyroxylin, having viscosities of 1/2 second and 18 seconds respectively, together with denatured ethyl alcohol, ethyl acetate and dibutyl phthalate.  If desired, pyroxylins of three or more different viscosities may be employed.  Instead of soluble pyroxylin there may be used other forms of nitrocellulose, other cellulose esters, e.g. cellulose acetate, or cellulose ethers, e.g. ethyl or benzyl cellulose.  The ethyl alcohol may be replaced by isopropyl, butyl or amyl alcohol, toluene, benzene, xylene, naphtha or combinations thereof, whilst the ethyl acetate may be used in conjunction with butyl acetate or may be replaced by other acetates, e.g. isopropyl, amyl or isoamyl acetate or "pentacetate," or by ethyl oxybutyrate, butyl or ethyl lactate, the mono-methyl or -ethyl ether of ethylene glycol, acetone or alkylene oxides, e.g. diethylene oxide, or mixtures thereof.  The dibutyl phthalate may be omitted or replaced by other plasticizers, e.g. other mono- or dialkyl phthalates, camphor or ethoxyethyl phthalate.  Specifications 346,397, [Group VII], 361,317; 363,623, [Group VII], 395,767, [Group III], 399,525, 406,030, [both in Group VII], 410,178, 411,815, and 411,920, [all in Group III], are referred to.  The Specification as open to inspection under Sect. 91 contains also a second example of an adhesive comprising "low viscosity ethyl cellulose B," "medium viscosity ethyl cellulose B," ethyl acetate, and dibutyl phthalate. This subject-matter does not appear in the Specification as accepted.
