[Class 17 (ii)] Athletic footwear, especially for practising ski-ing, comprises a boot having an upper in two sections articulated together to permit free bending of the foot in the forward direction while affording lateral support to the ankle joint. As shown in Fig. 1, stirrups 3 are attached one on each side of the vamp or lower section 2 of the upper of a boot to serve as runners for slides 4 carried by two rigid plates 5 on the upper section of the boot upper. This upper section is in two parts 8, 9 joined at the back and sides by a flexible collar 10 and adapted to be fastened by laces &c. at the front. Straps 15 passing through loops 16 secure the boot, which has side slits 17 to facilitate entry of the foot, and support the foot in practising ski-ing.

Title: Improvements in and relating to access ladders for aircraft
IPC: B64D9/00
Filed: 1948-12-14
Abstract: 651,123. Aircraft access ladders. BLACKBURN & GENERAL AIRCRAFT, Ltd., (formerly BLACKBURN AIRCRAFT, Ltd.), HAND, P. G. E., and WASS, G. R. Dec. 14, 1948, No. 32290. [Class 4] An aircraft access ladder is guided during its movement between projected and retracted positions by antifrictional guides and moved in both directions by an electric motor, and a flap which normally covers the opening through which the ladder is projected or retracted is so adapted that displacement beyond that necessary to permit the projection and retraction disengages the motor drive and allows manual operation of the ladder. A ladder comprising a pair of arcuate side members 1 and a plurality of rungs 2 is mounted for athwartwise movement on rollers 3. A reversible electric motor 6 projects the ladder through an opening in the fuselage normally closed by a hinged door 4. The motor is hingedly mounted about an axis 5 and drives the ladder through a reduction gear and a pair of rubber rollers 13 which are forced against the sides 1 of the ladder by a spring 15 anchored to the fuselage and to the motor frame. A cable 16 anchored at 17 to the fuselage passes round a pulley 18 on the motor frame and a pulley 19 its other end being attached to the door 4. A spring 21 acts on the mounting 20 of the pulley 19 and serves to keep the door 4 normally shut. Energizing the motor 6 in one direction projects the ladder against the door 4 which opens and compresses the spring 21. If the door 4 is opened farther than is necessary to allow projection of the ladder, the pulley 18 is displaced pivoting the motor 6 and disengaging the rollers 13 from the ladder which may then be projected or retracted manually. Energizing the motor 6 in the opposite direction will retract the ladder and allow the spring 21 to close the door 4. Limit switches 23, 24 are provided to switch off the motor automatically when the latter is fully retracted or extended.

Abstract: 436,261. Refrigerating. MOSS, E. W., 75, Victoria Street, Westminster.-(Ingersoll- Rand Co. ; 15, Exchange Place, Jersey City, New Jersey, U.S.A.) Nov. 9, 1934, No. 32356. [Class 29] Vacuum machines.-In a method of refrigerating by producing a vacuum in liquid containing chambers 4, 5, 6 and 7 and causing liquid therein to evaporate, the chambers are provided with independent vacuum regulating means in order to vary the refrigerating effect by varying the number of chambers in operation. The chambers are evacuated by steam ejectors 20 provided with independent controlling valves 23. Liquid is supplied to the chambers through branch pipes 12 and 13 from the supply pipe 2. Chamber 4 is always in operation and contains a float valve 29 to regulate the inflow of refrigerant. When the ejector of any other chamber is cut off pressure rises in the chamber and refrigerant cannot enter. The flow of refrigerant through the outlets 14 then causes the level in the chamber to fall. The pipes 14 are, however, made sufficiently long to retain some refrigerant therein under all conditions and thus maintain the chamber sealed.

[Class 4] A catapult device for launching aeroplanes, gliders, &c. is provided with two moving cables 14, 15 connected together at their ends and passing from a pulley-block device 1 over pulleys 18, 19 arranged on each side of the launching track 6, and thence between pulleys 8, 10, 9, 11 on the launching carriage 7 which is thus operated in the manner in which a cross-bow projects an arrow. When the carriage passes the pulleys 18, 19, the cables are withdrawn from the device 1 and the operating plunger lb is moved inwardly, thereby checking the momentum of the carriage and cables. In a modification, the launching track is mounted on a raised platform above a double-plunger pulleyblock device of the kind described in Specification 520,006, the united cables passing over guide pulleys and between pairs of pulleys arranged on each side of the track.

[Class 94 (i)] In wrapping spherical or lenticular cakes of soap and the like in viscose skin and the like, the wrapper is caused to enclose one half of the cake smoothly, and is laid on the other half in pleated folds, to form a package as shown in Fig. 4. A wrapper a, moistened in the centre, is positioned above a folding box 2 and is clamped in position between rings 3, 5 on the box and a folding plate 4 respectively. The article b is placed on the wrapper, and is pressed downwards to cause the wrapper to expand and envelop the lower half of the article smoothly. The ring 5 is lifted slightly and the plunger forces the article downwards. During this movement, teeth 1<1>, 41 on the plates 1, 4 fold the outer portions of the wrapper into pleated folds ready for application to the upper surface of the article. The teeth 4 are undercut at 7 so that the folds can be properly accommodated while being drawn radially inwards by the action of the plunger.
