Title: Improved method and apparatus for the production of spiral members from strips of veneer, veneer waste and the like
IPC: B66B1/16
Filed: 1955-01-14
Abstract: 764,419. Laminated wood; bending wood. LAMPE, F. W. H. Jan. 14, 1955, No. 1228/55. Class 145 Spiral members for forming the core of composite panels, doors or the like are made from initial veneer peelings, imperfect veneers or other veneer waste by cutting out strips of the correct length and height by means of a cross cutter 4 and multi-blade saw 12, serrating one of the surfaces by means of a serrated roller 20 and plain roller 21 and then forming the strips into spirals by means of an idle or driven serrated roller 22 and an adjustable deflector plate 24. To prevent variation in the height of the finished strips owing to varying spread of the wood under the pressure of the serrating roller, the veneer may be initially serrated between one or more pairs of serrated and plain rollers 6, 8 before passing to the saw 12. The depth and spacing of the serrations may increase from the beginning to the end of the strips by suitable formation of the serrated rollers. Feed rollers 1, 2 and 13, 14 and guideways 27 are provided and the waste edges of the veneer are removed downwards by a pivoted deflector plate 18 and rollers 19.

Abstract: 194,477. Dickson, J. Jan. 24, 1922. Gearing for stopping and starting machinery. - In stopping - mechanism for looms &c. having fast and loose pulleys a, b, Figs. 1 and 2, and a belt shipper fork d, a brake-strap e<1> with a friction lining partly encircles the fast pulley a and is pivoted at its lower end f so as normally to fall away from the pulley by its own weight. Its upper free end is connected by lever mechanism h, j to the lower arm k<1> of the lever k pivoted at l. This lever is provided with a block m acted upon by the shipper fork d, so that when the belt is moved on to the loose pulley, the lever mechanism is so actuated as to cause the brake-strap to be tightened, whilst when the belt is moved on to the fast pulley, the lever mechanism allows the brake-strap to slacken. In a modification, the upper end of the brake-strap is connected bv a flexible connection to the lever k and in another modification is connected to a lever p, Fig. 4, acted upon by the shipper fork and pivoted at p<1>. This latter modification may be used in looms wherein the fast and loose pulleys are mounted directly on the driving-shaft instead of being mounted on a side shaft geared to the driving-shaft by bevel gearing.

Title: Display indicator
IPC: G09F11/26
Filed: 1953-01-23
Abstract: 725,807. Electric selective signalling system. WESTINGHOUSE AIR BRAKE CO. Jan. 23, 1953 [Jan. 24, 1952], No. 2064/53. Class 40 (1). An electro-mechanical display indicator is operable to any one of an integral number of positions by an electric motor which drives two sprocket wheels of slightly different size geared to a belt containing the indications, wherein electrical contact fingers can be connected in various combinations by arcuate wipers driven by each sprocket wheel and are associated with the motor energizing circuit so that for each combination of positive or zero potential applied to the contact fingers the motor will be energized to drive the sprocket wheels into only one possible unenergized, rest position. As shown, two sprocket wheels 10, 11 (Fig. 1A) carry a notched belt 12 whose surface is divided into twelve symbol spaces of equal length, one of which is visible through a window in the housing. The circumference of wheel 10 is equal to three symbol spaces, and that of wheel 11 is equal to four symbol spaces. The wheel 10 is driven by a motor 14, and wheel 11 carries on its shaft a cam 16 and spring biased roller 17 to maintain alignment between a selected symbol and the window. Each wheel carries circuit controllers comprising an outer ring 18, 19 associated with brushes 20, 21 connected to one terminal of the motor 14, arcuate wipers 22, 23 associated with fingers 24, 25 connected to the other side of the motor via a battery and switch S, and two fingers connected via leads A, B, C, D to the contacts of four relays AR-DR, so that the energization circuit of the motor is dependent on the condition of the relays and the position of the wipers 22, 23. Thus each combination of selective energization of the relays causes the motor 14 to drive the wheels 10, 11 and belt 12 to the one only position in which the motor energization circuit is broken. Thus the indicated symbol is selected by a four element binary code signal applied to the relays AR-DR. In the position where the motor circuit is open the leads are indicated symbols, and by connecting the leads to further control terminals the indicator may be used as a transmitter.

IPC: G01S1/72
Filed: 1916-02-12
Abstract: 124,500. Davison, S. M. Feb. 12, 1916. Locating subaqueous sounds; subaqueous audible signals.-Apparatus for detecting subaqueous sounds and determining the direction of their source by rotating the apparatus until a maximum effect is obtained, comprises a " zoneplate " 1 having rings alternately transparent and opaque to sound, a telephone transmitter 2 being located on the axis. The maximum effect is observed when the axis passes through the source of sound such as a submarine bell 3. The opaque rings may be formed of two metal rings 4, 5 between which are rubber rings 6, 7, the space 8 being vacuous or containing a viscous liquid or light gas such as hydrogen. A modification is described in which layers of rubber, lead, felt, or like materials are used. The rings constituting the plate 1 are held in place by narrow acoustically insulated straps from one to the other. To increase the range of wave lengths which can be dealt with by a given plate, the distance A between the plate and transmitter 2 may be adjusted. To analyse the vibrations, the apparatus may be used in conjunction with a Duddell highfrequency oscillograph, Irwin optophone, or similar vibration-recording instrument. The range B at which sound may be detected may be increased by connecting the receiver to amplifying apparatus of the three electrode vacuum valve type, or utilizing electrical or acoustical resonance. According to the Provisional Specification, an opaque screen of circular, elliptical, rectangular, or other suitable shape may be used, or a telephone transmitter is placed at the back of a tube or megaphone and sound-insulating means added outside of this. Specification 29498/09 is referred to.

Title: Improved means for controlling machines for handling bottles and the like
IPC: B65G49/06
Filed: 1949-01-27
Abstract: 672,135. Endless conveyers. SCOTTS ENGINEERING (NEWPORT), Ltd., and BURDIN, N. V. April 26, 1950. [Jan. 27, 1949] No. 2222/49. Class 78 (i). [Also in Group XVII] Means for controlling a device for transferring articles, 'e.g. bottles, from a conveyer to a machine adapted to effect an operation on the articles consists in a movable control member at a side of the path of the articles, the control member being moved aside by a sideways spreading of a head of articles on the conveyer when the articles are against check means at the input of the transfer device so that the latter only operates when a head of bottles is correctly located at said input. The invention is shown applied to a machine for removing bottles from a conveyer to a capping or other machine of the kind having a pair of grippers 8 mounted on an oscillating shaft 9 as described in Specification 672,134. Such apparatus includes a stop 15 against which the bottles 1 are allowed to pile up, while the conveyer cables 4 slip on underneath. This piling up causes a sideways spreading of the bottles against a pivoted portion 20 of the guideway 5. The pivot rod 25 of portion 20 is coupled by a lever 26 to a link rod 28, the end 29 of which is held clear of a trip lever 30 of a clutch 21 provided that a head of bottles is present to push the member 20 outwards against the pressure of a spring 31. When sufficient bottles are not present member 20 moves into line with the guideway 5 and causes the end 29 of rod 28 to engage the trip lever 30. When so engaged the clutch 21 disconnects shaft 12 from a driving worm wheel 22 so that the cams 10, 11 which operate the grippers 8 and a reciprocating table 6 are stopped and the risk of jamming of bottles entering the grippers is minimised. Upon a head of bottles building up the trip lever 30 is released, coupling the driving wheel 22 to the shaft 12 so that the grippers 8 again operate on the bottles. A second pivoted portion 35 of the guideway may be associated with a second machine 33, e.g. a fillng machine, which supplies bottles to the grippers 8, so that if the head of bottles builds back too far, the spreading of the bottles against portion 35 causes this to cut off the drive to the machine 33.

Abstract: 561,698. Fluid - pressure servomotor control systems. HARBEN, J. E. Feb. 12, 1943, No. 2332. [Class 135] [Also in Group XXI] If the rate of flow through a sluice gate is excessive, the gate is closed automatically by hydraulic apparatus controlled by a paddle on the down stream side of the gate. The gate is raised non-automatically by a pump. The gate e is connected to a piston working in cylinder d having its upper end connected by pipe f to an oil or other liquid reservoir b and its lower end connected by a pipe to a hydraulic accumulator n and thence by pipe k<1> to valve k controlled by paddle h. The paddle is counterweighted at j in accordance with the maximum flow required, and has a mass at its upper end to locate its centre of gravity at the knife edge pivot i. The valve k when released by the paddle opens a return pipe k<2> to the reservoir so that the gate closes by gravity. When the piston in cylinder d has moved down past the upper end of pipe c<4>, free transfer of liquid from one side of the piston to the other is permitted under control of regulator c<5> to reduce resistance by the hydraulic system as the load on the gate increases. The gate is raised by a pump a connected by pipe a<1> and ball valve c to the lower end of cylinder d. Pressure causes valve c to close the transfer pipe c<4> and is applied over pipe k<1> to close valve k. Pipe k<2> has a non-return valve m.
