Title: An improved indicator lock
IPC: E05B11/02
Filed: 1928-06-16
Abstract: 317,943. Falconer, E. A. June 16, 1928. Keyholes, obstructing; key, retaining until bolt is operated; keys; staples for locks.-In a lock particularly for the door of explosive, poison, oil, or like stores where several persons have access and it is required to identify anyone leaving the door unlocked, the key is retained in the lock until the door is locked by shooting the bolt home into the staple, a fixed key or projection in the staple serving to release the key retaining device. As shown, a slides b mounted to have limited movement within the lock-bolt a has a notch b<1> which registers with the keyhole c, Fig. 1, when the bolt is shot into the staple d, Fig. 5, and so allows insertion and withdrawal of the key. When the bolt is withdrawn from the staple, Fig. 6, the movement of the key is arrested by a fixed stop f before completing a rotation and registration of the key bit with the key-hole is thus prevented. At the same time movement of the slide with the bolt is arrested by stop f engaging a projection b<2> on the slide, before retraction of the bolt is completed, so that slide is moved to the right relative to the bolt, and is locked to the bolt in this displaced position by the head of a pivoted catch e carried by the bolt engaging a recess b<3> in the slide. If the bolt is then shot with the door open, the notch b<1>no longer registers with the keyhole, so that the key cannot be withdrawn by merely shooting the bolt. When the door is properly locked by shooting the bolt into the staple, a fixed key d<1> in the staple, provided with suitable projections, engages the tapered free end of catch e, and moves the catch to release the slide, and then displaces the slide to the position shown in Fig. 5, in which the key may be withdrawn. When each individual is provided with a key the keys may be numbered &c. to identify the individual. When a single hey is provided, it may be kept in a device of the kind described in Specification 281,399 from which it can be removed only by insertion of an identifying token. To enable the user to pass the door, the key may have two shanks extending in opposite directions from the bit, so that it mav be inserted at one side of the door and removed at the other. According to the Provi. sional Specification the key may be made to leave a record of its use on a tape in the lock.
Patent GB-169523-A (GB)
Title: Improvements in automatic railway signalling and train control systems
IPC: B61L3/10
Filed: 1920-06-28
Abstract: 169,523. Howe, W. K. June 28, 1920. Fluid-pressure.-A slow-acting movement for the automatic application of the brakes is initiated and a warning signal is given when the speed of a train passes a prescribed maximum. If the driver then shuts off the power and applies the brakes manually the automatic action is prevented. A recording device is operated on the automatic application of the brakes, only if preceded by the warning signal and when the driver does not move his controls to the " power-off" " and " brakes-on-" positions. When a train enters a section next to an occupied section, a train-driven device progressively decreases the prescribed maximum speed in accordance with the braking performance of the train. A floating-lever 26 is supported at one end by a speed responsive device 22 and at the other end by a permissive speed determining cam K. When a danger condition of the track obtains and the magnet 35 is de-energized, a continuously-driven worm 38 falls into mesh with a toothed wheel 39 and rotates the cam K. When the roller 44 rests upon the part of the cam corresponding to the minimum permissive speed, a gap in the teeth of the wheel 39 causes a suspension of the rotation and the worm holds the cam in that position. The minimum permissive speed is the speed at which the train may enter an occupied section. If the speed as determined by the device 22 is, at any moment, greater than that permitted by the cam K, a rod 45 raised so as to lift an arm 48 from contact with a connection 114 to contact with a connection 111. This closes the circuit of a magnet 54 and a warning signal is given by a whistle W. It also breaks the circuit of a magnet 58 and the armature 59 commences to fall at a speed determined by a dash-pot 63. If the driver takes no action, the bridge-piece 61 ultimately closes the circuit of a magnet 69 and a brake-valve 66 is opened. If, however, the driver operates both the controller L to shut off power and the brake lever H to apply the service brake, a circuit to a magnet 57 is closed at c and b, the armature 59 is raised and the automatic application of the brakes is prevented. When the brake is fully applied, the brake lever may be returned to its normal position and the pressure in the brake system holds a piston 79 in a position in which it closes contacts 76, which then replace the contacts b in the circuit of the magnet 57. When the brakes are applied automatically, a bridgepiece 60 on the armature 59 closes a gap in the circuit of the magnet 70 of a recording device, but as this circuit also includes contacts 55, closed when the warning whistle is sounded, and contacts a and d, closed when the brakes are not applied and the power is on, a record is made only after a warning has been given to and ignored by the driver.

Title: Improvements in and relating to apparatus for drawing and severing glass tubing or rod
IPC: C03B21/02
Filed: 1935-06-21
Abstract: 440,995. Glass manufacture. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. June 21, 1935, 17861. Convention date, June 21, 1934. [Class 56] Apparatus for drawing glass tube or rod from a forming machine and for cutting it into lengths comprises an endless belt conveyer adapted to engage and move the tubing, a knife mounted on the belt, and means for moving the knife transversely to the tubing to score or cut the glass. Means for causing rotation of the tubing are also provided. The conveyer consists of two endless chains 11, 12, Fig. 1, provided with shoes 24, 17, respectively which are faced with pads, preferably of woven asbestos, to prevent them from marking the plastic glass when they grip the tube 10. The chains pass around wheels 36, 28 respectively, mounted on brackets 46, 34 which are clamped to a tubular standard 35. The chains may be arranged to run at a slight angle to one another and to the length of the tube 10, and in this case the tube will rotate on its longitudinal axis as it is drawn along by the conveyer. Both belts are driven by a shaft 63 which is housed within the tubular standard 35. The lower run of the chain 11 passes beneath a cam 69, and the upper run of the chain 12 passes over a track 72 composed of sections which are forced upwards by springs 80 to cause the chains to grip the tube 10. The tubing, which is at a high temperature, is severed or cut by knives 89 carried by the upper belt 11. Each knife is set in a block 90, Fig. 5, attached to a slide 91 which is movable at right-angles to the belt and also perpendicularly to a block 95 in which it is mounted. The knife is normally held out of contact with the glass tube, but is forced into contact with it, when a cut is to be made, by a cam 103 mounted in the lower surface of the bracket 46 and forced downward by springs 106. When the knife is in contact with the tube, it is moved transversely to it by a cam 109 and a spring 112, so that the glass is cut or scored. The knife is chilled by water which is circulated through a passage 113 in the slide 91 connected to flexible tubes 119. The knife is also moistened by contact with a roller 131, Fig. 1, on to which water falls from a pipe 132.

Title: Improvements in the preparation of dye-vats
IPC: D06P1/22
Filed: 1920-06-30
Abstract: Albumenoid matter of vegetable or animal origin is heated with caustic soda of 2-10 per cent strength to give products, of the type of protalbinic and lysalbinic acids, for use in preparing dye-vats. In an example, a product is obtained by heating casein with dilute caustic soda solution, cooling, adding calcium hydrate and a little magnesia, stirring, neutralizing with formic acid and evaporating to dryness in vacuo.ALSO:In dyeing animal fibres with vat dyes products similar to protalbinic or bysalbinic acids, and obtained by heating vegetable or animal albumens with caustic soda of 2-10 per cent strength for 2-3 hours at 80-85 DEG  C., or their alkali salts, are added to the dye vats; brighter shades are thereby obtained and the fibres remain softer, and become more elastic and glossy.  The vats may be made neutral or slightly acid.  In an example, a vat contains indigo MLB, sodium hydrosulphite, and hydrolyzed casein product, and is neutralized by formic acid.  The casein product is obtained by heating casein with dilute caustic soda, cooling, adding a little calcium hydrate and magnesia, stirring, neutralizing with formic acid and evaporating in vacuo.  The Specification as open to inspection under Sect. 91 (3) (a) refers also to the dyeing of mixed goods. This subject-matter does not appear in the Specification as accepted.

Title: Apparatus for machining rolls for rolling mills and the like
IPC: B23B5/10
Filed: 1931-06-22
Abstract: 381,151. Machining rolls for rolling - mills. MANNESMANNRÍHREN - WERKE, 1B, Berger Ufer, Dusseldorf, Germany. June 22, 1931, No. 18055. Convention date, Dec. 24, 1930. Addition to 353,829. [Classes 83 (ii) and 83 (iii).] Planing.-The apparatus described in the parent Specification for machining Pilger rolls and the like is modified by arranging the segmental cams 18 to move the tool 2a positively in the outward direction while additional cams are arranged to effect the inward movements of the tool as the inclined portions ao, ob of the roll groove are cut. In Fig. 3, the additional return cams 50 are inwardly urged by adjustable springs 51 and coact with a roller 52 mounted on the tool holder. During the outward movement of the tool holder while the tool cuts along the line ao, the tension of the spring 51 is increased, the tension being relieved as the tool holder is moved inwardly during the cut along the line ob. In a modification, Fig. 5, the spindle 28 which controls the cutting radius of the tool is geared to a pair of screwed spindles 59 working in nuts 60 connected by levers 61, 62 to blocks 63 connected to one end of the springs 66 of the return cams 65. In a further modification, Fig. 6, fixed cams 67 mounted in guides 53 are provided with nuts 75 coacting with screwed spindles 74 driven through gearing from the spindle 28. The position of the cams thus varies with the radial position of the tool holder and is always such that the tool is moved, while cutting the roll sides, in a direction tangential to the circular tool movement. In some cases the cams may be carried on the tool holder and their coacting rollers on the machine frame.
