Abstract: 347,136. Fluid - pressure brakes. EDGE, S. H. and CLAYTON DEWANDRE CO., Ltd., Titanic Works, Lincoln. Jan. 22, 1930, Nos. 2258 and24029. [Class 103 (i).] A braking system for vehicles comprises a manually operated brake and a vacuum brake gear coupled by a balance lever connected to a brake pedal, so that force applied to the pedal is distributed between the manual brakes and a reaction valve controlling the vacuum brakes so that the brakes are applied proportionally. The movement of the compensating mechanism is limited by stops to prevent failure of one gear impairing the operation of the other. The brake pedal 2 of a motor-bicycle is pivoted on a lever 4 connected to the rear wheel brake. The free end of the pedal 2 is normally opposite the fulcrum of the lever 4 and is connected by a rod 6 to the valve 7 for the front brake operating vacuum cylinder 11 actuated from the engine intake 8. The valve is adapted to exert a reaction on the link 6 proportional to the degree of vacuum in the cylinder. The front brake can also be operated manually by a cable 14. In an arrangement for a motor car the brake pedal is connected to one end of a balance lever, a rod to the rear brakes being connected to the centre of this lever and the valve for the front brake cylinder being connected to the other end of the lever. The brake cylinders are mounted on the stub axles, or a double acting cylinder can be arranged midway between the two wheels. In another arrangement the front brake cylinders are mounted on the chassis and a hand-lever is also provided to operate separate rear brakes. In another arrangement the brake cylinders are double acting and assist the application of the rear brakes. A further modification of the invention is shown applied to a servo brake as described in Specifications 256,560 and 256,561, [both in Class 103 (i), Brakes &c.], the floating lever operating the control valve in these devices acting as the balance lever between the manually and the vacuum applied brake. A pipe is connected from the servo cylinder to the brake cylinders actuating the front wheel brakes and the servo piston assists in the operation of the rear brakes. The vacuum actuating mechanism may actuate the rear brakes and the manually operated mechanism the front brakes. The manually operated mechanism may operate the brake on one wheel only and the vacuum mechanism the brakes on the remaining wheels.

Title: Apparatus and a method which may be used in the manufacture of honeycomb structures
Inventor: BARNES JAMES KEITH
IPC: B31D3/02
Filed: 1964-01-17
Abstract: 1,017,730. Cutting webs. BONDED STRUCTURES Ltd. Dec. 11, 1964 [Jan. 17, 1964], No. 2270/64. Heading B4B. Apparatus for cutting a web 3 to which lines of adhesive 4 have been applied comprises two sensing elements 1, 2 having their sensing points at 11, 12, the signals from the sensing elements being alternately selected by an electronic gating circuit 5 and fed to a digital counter 6. After a number of signals predetermined by the setting of a length setting switch 13 has been received by the counter, the output of the counter initiates the operation of a cutting device 7. At the same time, a signal is sent to the gating circuit so as to switch the counter to receive signals from the other sensing element. After the same number of signals from this element, the cutting device 7 is again initiated, a signal is sent to the gating circuit 5 to switch the counter to receive signals from the first sensing element and the sequence of operations repeated. Preferably, a signal from the counter, initiated after receipt of a lesser number of signals determined by the setting of a length setting switch 13, switches in a resistance 10 to reduce the power supplied to an electric motor which drives the pair of feed rollers 8, 8<SP>1</SP>, thus reducing the speed of the web to the sensing elements. On receipt of the greater number of signals corresponding to the desired length of the cut sheet, a further signal from the counter switches out the resistance 10 after effecting cutting of the web. The cut sheets are conveyed away by a pair of rollers 9, 9<SP>1</SP> and stacked. The edges of the cut sheets may be aligned manually or by means of a joggle box. The stack of cut sheets in which all of the lines of adhesive are parallel may be caused to adhere together and be cut through to form a slice which can then be opened out to form a honeycomb structure.
