Patent GB-546829-A (GB)
Title: Improvements in or relating to mine and like haulage or hoisting installations
IPC: B66B17/02
Filed: 1941-02-10
Abstract: 546,829. Hoisting installations. ROSTON, H. L. Feb. 10, 1941, No. 1785. [Class 78 (v)] In haulage or hoisting installations, means are provided for maintaining constant tension in the cable, within small limits, when undue sudden strain is thrown thereon, and for signalling and/or recording excessive strain. The cable X passes over a floating sheave 1 journalled on a frame 3 pivoted at 5 to a platform 4 and supported at its outer end by links 3a pivoted at 6a to the upper ends of piston rods 6. The rods 6 carry pistons 7 moving in cylinders 8 connected by a manifold 16 to a piston valve 12. The valve rod 10 is pivoted to the end of a lever 9 hinged at 9a and rocked by the pivot pin 6a. Added strain to the cable X brings down the pistons and moves the valve rod 10 to admit fluid pressure below the pistons, till the position of the sheave is restored. Lowered strain on the cable allows the fluid pressure existing beneath the pistons 7 to raise the sheave and move the valve rod 10 to put the lower parts of the cylinders 8 in communication with the atmosphere, thus restoring the status quo. Excessive change of strain, however, gives the lever 9 an abnormal degree of rocking, and brings a blade 18 into touch with contacts a, b, c, d, e whereby electrical or other indications of the change are given to the operator, with or without recording thereof. Total failure of fluid pressure will bring the contact e against the blade 17 to give such indication, and very high strain will connect the contact a to stop the cable drive automatically.

Abstract: 606,775. Loading vehicles. SHERWOOD, J., and ALLCHURCH, S. Jan. 18, 1946, No. 1811. [Class 78 (iv)] In a vehicle for collecting refuse of the kind in which the refuse is first loaded into a filling box e, Fig. 1, attached at f to a collecting body d and is then transferred from the box to the body by rotating the latter, this operation being repeated each time the box is filled until the body is full, the movements of the body are effected by means of two telescopically assembled tubes l, m, which are extended and contracted by means of hydraulic pressure, the lower end of the tube l being pivoted to a base n mounted on the chassis and the lower end of the tube m being either in sliding contact with the body or prevented from sliding when the body is to be rotated. The lower end of the tube m carries trunnions o which slide between guide rails p, secured to the body. The trunnions are retained in position at each end of the guide by pawls q, Fig. 3, which can be moved to release the trunnions by actuatlng a lever r. When it is desired to load the body the trunnions are released from the lower pawls and the tubes extended by hydraulic pressure until the trunnions are held by the upper pawls. The tubes are then contracted to cause rotation of the body and discharge of the box into it. The body is returned to normal position by reversing the operations just described. When refuse is to be discharged from the vehicle, the trunnions are locked by the lower pawls and the tubes extended.

[Also in Groups VI and XIII] An ice lolly mould, preferably for use with multiplate refrigerating apparatus, comprises a shallow mould tray 1 divided into rows of compartments 2 to 4 and to a stick holder having locators and retainers for a number of sticks, the locaters being arranged so that when the stick-holder is loaded with sticks and inverted over a mould tray each stick is inserted into a compartment at a shallow angle to the base of the mould tray. The two of compartments 2 is offset from the rows 3 and 4, and adjacent compartments are connected by holes 8. The stick-holder, Fig. 2, is a rectangular plate 11 having ribs 12 to 15 and polythene spacers 18, 19 as shown, through which rods 20, 21 pass. Each stick is placed in a notch 16 in one of the ribs 13 to 15 so that one end is passed under one of the rods and abuts the base of a rib. The three points of contact of the stick with the holder are not in a straight line and the stick is thus located and gripped firmly in position. The notches of the rib 14 are offset to avoid interference between the sticks. After freezing weighted or spring clips are placed under the stick-holder and the tray is then rested by means of its handles 9, in a bath of warm water. When the frozen material ceases to adhere to the tray, the clips raise the stickholder clear, ready for removal. Specification 345,618, [Group XIII], is referred to.

Title: Improvements in or relating to electronic microscopes
IPC: H01J37/147
Filed: 1948-01-22
Abstract: 660,787. Electron microscopes. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Jan. 22, 1948 [Jan. 25, 1947], No. 1946/48. Class 39 (i). To facilitate finer adjustment of the focusing in an electron microscope, means are provided whereby the angle of incidence of the cathode-rays on the object plane is rapidly varied to produce a blurring of the image on the screen which can be detected by the eye. The rays may be deflected magnetically or electrostatically to produce 'a linear circular or elliptical trace on the object plane; alternatively, the electron gun, or the condensing lens may be vibrated. In one form, the container comprises a metal part 8, Fig. 4, housing magnetic or electrostatic lenses 15, 17, a window 18 through which the fluorescent screen 10 can be viewed, and the objectholding tap 7. A metal part 5, secured to the anode of the gun 13, houses the condensing lens 19 and is sealed to the glass parts 4, 6. The tube may be continuously evacuated through pipes 1, 2. Pairs of deflecting plates 20, 21 are used to produce larger angles of incidence of the rays on the object plane during focusing tests. The length of the plates 21 or the alternating or pulsating potentials thereon are greater than that on plates 20. It may be desirable, e.g. in the case of thin objects, to focus on the screen a plane which is closely adjacent to the object plane. This may be secured subsequent to the accurate adjustment of the focusing by the circuit arrangement shown in Fig. 6, whereby simultaneous operation of the switches 35, 36, 37, Fig. 6, used to earth the deflecting plates 32, throws the adjustable resistance 38 into the circuit of the objective coil 33 to secure the required amount of defocusing. The deflection system may be modified for stereoscopic work by the provision of separate eye-pieces in a mask, alternately covered by a rotating disc, the movement of which is synchronized with the deflecting potentials which preferably are sinusoidal modified by a strong third harmonic. The Specification as open to inspection under Sect. 91 states also that a vibrating apertured diaphragm may be used to vary the angle of incidence of the beam on the object plane. This subject-matter does not appear in the Specification as accepted.
