Patent GB-608798-A (GB)
Title: Improvements in or relating to reaping machines
IPC: A01D45/06
Filed: 1946-03-01
Abstract: 608,798. Flax harvesters. BOWKER, J. A. March 1, 1946, No. 6343. [Class 6(iii)] A flax harvester comprises a travelling frame having a plurality of spaced grippers which move in an endless path extending longitudinally of the frame and which can be projected and retracted transversely to the frame when in the lower run of said endless path and to perform a gripping action intermediate of said projecting and retracting movements whereby to grip the stalks to be reaped. One of each pair of grippers may move towards the other. In the construction shown, an independent engine on the chassis drives a conveyer 16 on the individual plates 15 of which are mounted the gripper elements. In addition two systems of chains 24, 26 and their associated spades 25, 27 are also driven by the engine, but in opposite directions to each other. Each plate of the conveyer has a pair of transverse guides 35, 36 the latter having inclined branches 37 towards the guide 35. The pairs of gripper elements 38, 39 move along these guides by means of slides 40, 41 having pins 40a 42 engaging with said guides. Each gripper element has upward projections or pins 52, 53 with which the spades engage and thereby move said elements transversely as the conveyer moves them longitudinally of the chassis. The element 38 is to the right of the element 39 on each plate as seen in Fig.4 , and therefore the pin 53c will be carried down to a greater extent than pin 52c, whereby pin 52c does not, but 53c does, engage with an inclined face 60 of an abutment slidable in a guide against a spring. Engagement with said face causes each pin 42 on the slide 41 to move along the inclined portion 37 of the guide 36 and thereby approach the gripper element 38 of the same plate. A guide rail 65 maintains the elements in proximity for a short time. The return of the element 39 away from element 38 is effected by an inclined plate 80 approximately parallel to the face 60, said plate being operated through a lever system by a cam in timed relation with the conveyer so that when each pin of each element 39 reaches the position of 53d the plate 80 moves it in the direction necessary to withdraw pin 42 from the inclined portion 37 of the guide 36. The gripper elements are retracted when their pins 51, 53 are engaged by spades 27 on chains 26. To retain them in the retracted position whilst they move along the upper run of the conveyer a guide 29 (see Fig. 2) has channels to receive the pins 51, 53. A clamping device for holding together the free ends of approached gripper elements comprises a spring actuated lever system, Fig. 8 (not shown). A vertical dividing frame transverse of one side of the chassis is secured thereto by tubes one of which acts as a pressure element to apply pressure on the stalks near the ground after they have been gripped.

Title: Improvements in aircraft wheel and brake assemblies
IPC: F16D55/41
Filed: 1949-03-09
Abstract: 677,243. Cooling brakes. DUNLOP RUBBER CO., Ltd., and BUTLER, H. J. Feb. 20, 1950 [March 9, 1949], No. 6381/49. Class 103 (i). An aircraft landing-wheel and brake assembly comprises an annular frusto-conical member, within and coaxial with the wheel, for directing cooling air into contact with the brake friction elements, the large diameter end being secured to the inner periphery of the wheel rim remote from the brake, while the small diameter end is located adjacent the inner periphery of the brake. As shown, air is forced through the wheel by a retractable deflector 33 as described in Specification 654,496, the inner surface of the air passage being formed by the wall of the hub 3 and the outer surface by the frusto-conical member 31 whose larger diameter end is connected to the wheel rim 1 and smaller diameter end is connected to the brake. The progressive reduction in area of the passage causes the cooling air to be discharged at high velocity radially over the brake friction elements. Unheated air passes through slots 32 in the member 31 and over the interior surface of the rim 1, and assists in forcing the heated air from the brake out of the wheel, thus preventing hot air from impinging on the rim. The brake construction shown is that described in Specifications 631,880 and 660,209. Specifications 625,726, 654,499 and 677,233 also are referred to in the Complete Specification, and Specification 641,665 in the Provisional Specification.

Apparatus for testing a sizing liquid includes a viscosity meter and an instrument for measuring the adhesive power of the liquid (not shown), the viscosity meter including a closed chamber 3 and means 6 to measure the pressure in the chamber connected by a conduit 32 to an aperture 31 communicating with the air space above the liquid. The liquid to be tested is pumped from the tank 1 into the chamber 3 by a pump 2. It then returns through a restriction 52 into the tank 1. The pressure above the liquid in the chamber 3 is a measure of the viscosity and is indicated and recorded by an instrument 6. A temperature-sensing element 7 allows the temperature also to be indicated and re - corded. To prevent penetration of the liquid into the instrument 6, a float 34 is provided which closes the connecting conduit 32 when the level of the liquid in the chamber 3 is too high. Furthermore, the conduit 32 slopes downwardly from the instrument 6 to the chamber 3 and a condensation chamber (not shown) is provided between the instrument 6 and the conduit 32.
