Patent GB-833427-A (GB)
Title: Means for minimising the escape of a gas or vapour in atomic form from a casing in which it is produced
Inventor: SCOTT WILLIAM JOSEPH
IPC: B01J19/00
Filed: 1955-05-18
Abstract: The escape of hydrogen or other gas or vapour in atomic form by permeation through an envelope or casing is minimized by enabling the atoms to recombine within the envelope.  When the medium is hydrogen a shield of material such as boro-silicate glass which is relatively impervious to atomic hydrogen may be interposed between the source at which the atoms originate and the permeable portion of the casing or envelope.  Alternatively a shield of iron, nickel, platinum, palladium or other metal permeable to atomic hydrogen may be spaced from the wall of the envelope so that atoms after permeation through the shield combine or re-combine into molecules which return around the shield to the interior of the envelope.  If the shield is made in more than one section, the joints between the sections may be protected by an over-lapping screen.  Further alternatives comprise a screen of porous material containing self-venting apertures in which the atoms re-combine, tooth-like projections on the inner surface of the wall into which the atoms penetrate and then re-combine in the spaces between the teeth, a covering of wide gauze or an adherent layer of porous material, e.g. metal powder sintered in position on the inner surface, or the inner surface of the wall itself may be made porous to provide self-venting cavities.  A T.R. cell, a T.B. cell and a nuclear reactor embodying the invention are described (see Group XL (a)).

Abstract: 558,344. Wooden propellers. HILLS & SONS, Ltd., F., and CHOWN, W. R. Oct. 17, 1942, No. 14569. [Class 114] In a wooden propeller blade constructed from laminale of reatively higher and lower density, some of the laminae a have relatively higher density root portions b spliced thereto. The laminae a may be of the same width as the diameter of the root, and have nose and/or tail pieces c, d glued to their edges. They are assembled alternately with laminae of low density veneer, a minor proportion of the veneers of which have their grain arranged at right angles or otherwise transversely to the longitudinal axis of the blade. Extra spliced boards may be used to increase the density of the root, and the whole is then glued in a press.

Title: A machine for slicing and applying butter or the like to bread
IPC: B26D7/34
Filed: 1949-06-01
Abstract: 666,909. Buttering and slicing bread. LEE, W. S. K. Aug. 28, 1950 [June 1, 1949], No. 14646/49. Class 28 (i), 28 (ii). In a machine for buttering the cut face of a reciprocated loaf and then cutting off the buttered slice the butter on a wire mesh is softened by an electric or other heater 44 which overlies the mesh but is reciprocated away on its guide rail 46 when the loaf slides over the buttering wire mesh. The butter is forced through the wire mesh cover of an orifice by a step-by-step pushed piston 28 and after the loaf end is reciprocated over the wire mesh to get buttered the loaf becomes held by a pivoted spring loaded clamp 24 during the slice cutting by the back reciprocation of the loaf against the rotated disc knife 10. The clamp 24 is pivoted up about 25 off the loaf by a fixed cam during reciprocation of the loaf carriage and is allowed to return by a spring. The loaf is fed towards the knife 10 by a pusher 17 pulled by a cable 18 wound on a spring loaded drum 20. A winding key 21 on the drum determines the amount of the pull and the push. The amount of butter fed at each small advance of the piston 28 inside its butter containing cylinder 17 can be varied by adjusting the amount of the ratchet and pawl feed 40, Fig. 3, by means of a knob moving an arcuate shield for the pawl. The pawl &c. actuates through gearing and dog clutch a rack and pinion drive 30 to the piston rod 29. The butter cylinder is transparent. It can be refilled by disconnecting the dog clutch 25 and pivoting it up to vertical position for hand Riling.

The apparatus forms part of a die bonder machine in which dice are transferred singly from a table 33 to a bonding position at which the die is bonded by thermocompression bonding to a transistor strip precisely located and clamped over a heater which brings the strip to a temperature of 435-500 C. within five seconds. The pick-up device is mounted by leaf springs 43 on the end of the transfer arm and may be lowered and raised by cam-controlled operation of a push rod 41 and bell crank 36. The pick-up device (Fig. 3) includes a floating spring-biased quill 34<SP>1</SP> enclosing a vacuum tube 44 for picking up and holding the dice, the spiral coil spring 40 being designed to exert adequate bonding pressure when a die is pressed on to a transistor strip. The transistor strips are indexed by a mechanism (Figs. 10, 11, not shown) including two sets of rollers each having a drive roller and a nip or pressure roller, the former being driven by a stepping motor pulsed from a photo-electric control mounted on the drive shaft of can 73. A fibre optics strip sensor and hole sensor are mounted on the mechanism and respectively sense the presence of the transistor strip by means of a reflective strip thereon and the presence of an indexing hole and control the operations of the machine independence thereon. A vertically movable strip locator and clamp releases the nip rollers as it moves to index and clamp the strip so that the strip is free to float before locating pins enter the index holes for precise positioning and clamping.
