Title: Improvements in moving staircases, escalators and like passenger conveying installations
Inventor: LANDSCHULZE ERNST AUGUST
IPC: B66B29/00
Filed: 1959-08-11
Abstract: 890,312. Escalators. RHEINSTAHL HAMBURG STAHLBAU EGGERS & FRIEDRICH KEHRHAHN G.m.b.H. Aug. 11, 1959, No. 27407/59. Class 78 (1). In an escalator provided with a service brake and an emergency brake, the emergency brake is adapted to be operated if the escalator is unintentionally run in reverse, but is not operated when it is intentionally run in reverse. For this purpose two discs 1, 1<SP>1</SP> are mounted to rotate together on a shaft driven by the escalator drive, the discs having notches 1a, 1b respectively, the latter being adapted to be engaged by a pawl 2<SP>1</SP> on a lever 2 whilst the former are engaged by a roller 3 carried by the pawl and resting by gravity on the disc 1. Lever 2 is pivoted to a two-armed lever 5, 5<SP>1</SP> pivotally mounted at S and connected by a cable 6 with a control for brake-actuator motor 7. A compression spring 11 normally holds lever 5, 5<SP>1</SP> in the position shown. When the escalator travels forwards discs 1, 1<SP>1</SP> rotate in direction a so that pawl 2<SP>1</SP> cannot engage notches 1b, the speed of rotation of the discs being such that roller 3 engaging disc 1 maintains pawl 2<SP>1</SP> clear of the disc 1<SP>1</SP>. When the escalator unintentionally runs in reverse pawl 2<SP>1</SP> engages one of the notches 1b so that lever 2 is moved and with the assistance of spring 11 now acting over centre turns lever 5, 5<SP>1</SP> to actuate the control for motor 7 to apply the emergency brake. When the escalator is intentionally run in reverse a solenoid 9 is actuated to raise a pin 10 which lifts lever 2 sufficiently for pawl 2<SP>1</SP> to remain clear of the notches 1b.

Title: Accelerometer
IPC: G01P15/03
Filed: 1961-07-28
Abstract: 972, 826. Accelerometers. L. BOLKOW, [trading as BOLKOW ENTWICKLUNGER K.G.]. July 28, 1961 [July 28, 1960], No. 27457/61. Heading G1K. An accelerometer comprises a pendulum 2 which is angularly deflected about its pivot 3 against the action of a spring 4 in response to translatory accelerations of the platform 1 on which it is pivoted to supply a measured value of this acceleration, the pendulum 2 being so constructed and mounted that any rotational accelerations about a preferred axis X around which the platform can rotate have no influence on the measured value. This is achieved by making the moment of inertia of the pendulum about its pivot 3 equal to the product of its total mass, the distance of its centre of gravity 5 from the pivot 3 and the distance of the pivot 5 from the axis X. In the embodiment shown the pendulum is pivoted by means of a torsion rod 5 of cross-shaped section which is rigidly clamped at each end and has considerable bending resistance but small torsional stiffness. In a modification the torsion rod is clamped at one end only and carries the pendulum mass at its other end.

Title: Improvements in apparatus for the production of hollow ingots
IPC: B22D27/11
Filed: 1932-10-05
Abstract: 408,013. Casting-machines. JONES, E. F., and MAUSS, W., Victoria Station House, Victoria Street, London. Oct. 5, 1932, No. 27679. Addition to 402,096. [Class 83 (i).] In a machine for forming hollow ingots as described in the parent Specification the collar 17 is actuated by opposed hydraulic cylinders 20, 21, fluid at a higher pressure preferably being used for the consolidating stroke. Figs. 3 and 4 show the control valve 27 in section on lines III-III and IV-IV. Low pressure fluid 8 is admitted through a non-return valve 44 to a passage 29 which is first connected to the cylinders 20 by a drum-controlled valve 10 admitting fluid to the end 33 of the valve 31 and forcing it to the left. This also connects the cylinders 21 to exhaust 30. A valve 11 then admits fluid to a piston 35 which moves the valve 31 to its mid-position thus holding the collar against movement. After the valve 13 has caused the lowering of the plunger 5 a valve 12 admits fluid to a piston 43 of a self-closing valve 42 which is thus opened to admit high pressure fluid 39 to the passage 29, valve 11 at the same time releasing the pressure on the piston 35 so that the valve 31 again moves to the left and admits the high pressure fluid to the cylinders 20 for the consolidating stroke. The valve 11 again acts to lock the collar, the plunger 5 is raised, the valve 12 releases the high pressure valve 42, and the valve 10 causes the valve 31 to move to the right to admit fluid pressure to the cylinders 21 and raise the collar.

Title: Improvements in or relating to control valve for hoists and the like
IPC: B66D3/22
Filed: 1955-09-30
Abstract: 791,927. Manually-actuated valves. ARO EQUIPMENT CORPORATION. Sept. 30, 1955 [Feb. 28, 1955], No. 27868/55. Class 135. [Also in Group XXX] A control valve for a pneumatic motor driven hoist comprises a member 60 slidable in a sleeve 30 and actuated through rakc and pinion gearing 74, 76, 80 by a lever 84 which is fixed to a shaft 82 and rocked by the pulling down by an operator of either of a pair of flexible elements 86, 88. The shaft 82 also carries a cam 102 for releasing a brake consisting of shoes 92, 94 having linings 98 which are held in engagement with a drum 90 by a spring 100. Air under pressure is supplied to a passageway 36 where it has access to each end of the valve member which has a head at each end separated from a central part by reduced portions 62, 64. Ports 40, 42 lead to the motor whilst ports 48, 50 are exhaust ports. When the valve member is moved to the left from the neutral position shown to bring a sealing ring 70 on the head 66 beyond the end of the sleeve 30 compressed air is admitted to the port 40, and the ports 42, 50 are interconnected so that the motor is driven in the lifting direction. The brake is arranged to be released after power is applied to the motor so as to prevent slippage of the load. When the lever 84 is moved in the opposite direction to effect lowering of the load on the hoist the brake is released before the valve head 68 moves out of the right-hand end of the sleeve 30 whereby the descending load drives the motor as a pump. Further movement of the valve member to the right first partially opens the exhaust port 48 to reduce the resistance to rotation of the motor and subsequently connects the port 42 with the air pressure supply to cause the motor to be driven positively in the downward direction.

IPC: B30B9/30
Filed: 1931-10-09
Abstract: 386,059. Hydraulic baling presses. FAWCETT, PRESTON, & CO., Ltd., 17, York Street, Liverpool.-(Manson, J. E.; Narayanganj, Eastern Bengal, India.) Oct. 9, 1931, No. 28024. [Class 94 (i).] Relates to hydraulic baling presses for cotton, wool, &c. of the type having revoluble baling presses for the reception of the loose material and its conveyance into the press, or of the type in which are combined a preparing press and a finishing press, and having, with or without revoluble baling boxes, revoluble transfer chambers to convey the partly - pressed bales from the preparing press to the finishing press; the type shown is the latter, without revoluble baling boxes. The revoluble transfer chamber 13, containing a partly pressed bale, rotates to the left, as shown in the Figure, to transfer the bale to the finishing press. The invention consists in retarding and cushioning the impact of the chamber 13. As the chamber 13 rotates it makes contact with a roller 26 of a crank lever 24 pivoted at 25, depressing, via links 27, a ram 17 working in a dashpot cylinder 16, from which a working fluid such as oil of low viscosity is ejected through an escape valve (not shown) being returned by a pipe 21 to a reservoir 18. The rate of egress of the fluid from the dashpot cylinder 16 is controlled by an adjustable needle valve (not shown). Fluid is returned from the reservoir 18 to the dashpot cylinder by a pipe 22. The chamber is thus retarded and stopped above the finishing press table 10, and the lever 24 is now in the dotted line position. When the chamber 13 moves on to the left. a weight 28, or spring, restores the lever &c. to their normal positions as shown in full lines in the Figure.
