Title: Improvements in slicing machines
IPC: B26D1/143
Filed: 1927-10-27
Abstract: 280,883. Maatschappij tot Vervaardiging van Snijmachines Volgens van Berhel's Patent en van Andere Werktuigen. Nov. 19, 1926, [Convention dots]. Cutting slices in succession.-In a disc-knife reciprocating table machine, the connecting-rod for reciprocating the table is connectible to or disconnectible from the table, and is characterized by the connecting-rod, when disconnected, being controlled by a member slidably mounted on the table. As shown in Figs. 1 and 2, the connecting-rod c is connected to a pin h carried by a block i slidable in a guide k on the table d which is slotted at k' to receive the pin h, and is normally reciprocated along guide-rods e, f. The block is locked to the table d by a rod l, pressed by a spring r into a recess m in the side of the block i. The rod l is disengaged by pulling out the knob n and is retained in the retracted position, to permit the knife to rotate without reciprocation of the table, by rotating the knob to engage the projection o with the side of the table. To re-engage the rod l with the block e, the knob n is turned back to allow the projection o to enter the recess p. The end of the rod l rides up an inclined ramp on the block i, into the recess m.
Patent GB-840191-A (GB)
Title: Films of polypropylene
Inventor: BLOOM GEORGE ISAAC MAURICE
IPC: B29C48/03
Filed: 1957-09-11
Abstract: <PICT:0840191/IV(a)/1> <PICT:0840191/IV(a)/2> Flat or tubular isotactic polypropylene film made by meltextrusion and quenching is introduced into a narrow heating zone where it is rapidly heated while travelling past an infra-red heater to a temperature between 120 DEG  and 170 DEG  C., and is stretched during or immediately after its passage past the heater in at least the longitudinal direction, so that a uniformly-stretched film oriented in at least one direction in the plane of the film is obtained.  The film may be pre-heated, preferably to 80-110 DEG  C., before being subjected to the rapid heat treatment, and a heater may also be provided in a suitable position to prevent the film from losing the heat imparted to it in the rapid heating step before stretching has been completed. After the rapid heating the film may be cooled.  Preferably the film is stretched 4 to 10 times in any direction chosen.  As shown, a flat film is passed from extruder 1 via quench bath 2 and nip rolls 3 to a heated roll 7, and is then stretched between roll 7 and cooled roll 8 while it is heated rapidly to 120-170 DEG  C. by infra-red heater 4. The film then passes to draw rolls 5, which rotate at a higher peripheral speed than rolls 3, and is wound up on reel 6.  A tubular film may be stretched substantially simultaneously both longitudinally and laterally.  As shown, film passes from annular extrusion die 11 through cooling and drying means (not shown) to nip rolls 12, and is inflated by means of the tubular probe 13.  The film is rapidly heated to 120-170 DEG C. by the annular infra-red heater 14 and is stretched between rolls 12 and the cooled rolls 18, which rotate at a higher peripheral speed than rolls 12.  The circular heater 20 provides heated air in the stretching region and so prevents loss of heat from the film during stretching.  The film is progressively flattened by rolls 15 and 16, while infra-red heaters 17 heat the film to approximately the stretching temperature, and is wound up on reel 19.  Specifications 542,509, 687,532, 719,093, 741,963, 787,479, 812,387 and 822,704 are referred to.

Abstract: 728,690. Seats convertible into beds. SLUMBERLAND, Ltd. Dec. 7, 1953 [Nov. 14, 1952], No. 28727/52. Class 52 (2). An easy chair or seat convertible into a chaise longue or bed comprises a rigid base 10, 11, 12, or frame of shallow box form, an upholstered back unit 13 hinged to the rear part of the base, an upper seat 19 hinged at its rear end to the back unit 13 and supported at its front end by the base, e.g. by lugs 20 and a lower seat unit 21 hinged to the front end of the upper seat unit and adapted to fold under that unit within the base or to be swung out to form a forward extension of the upper seat unit. The seat units may be wedge-shaped. As shown in Fig. 6, a transverse spindle 14 passes through brackets 15 fixed to the sides of back unit 13 and is fixed to the side walls of the base. Each bracket has a lug 16 to which a plate 18 fixed to the side of the upper seat unit, is pivoted (Fig. 7). Movement of the back unit will therefore cause corresponding movement of the upper seat unit since it is free to move longitudinally on lugs 20 along the side walls 10. The back unit 13 is angularly adjusted by raising the trigger 32 which, through a link 31 and lever 30, rotates a sleeve carried on spindle 14, which causes the arm 26 and lever 27 to lower a rod 24, guided in slots 25 in brackets 15, out of engagement with toothed sectors 23 fixed to the base and concentric about the spindle 14. On release of the trigger 32, a spring 34 biases the rod 24 into the locking position. Fabric 33 over the rear surface of the back unit conceals all the mechanism except the trigger 32. For conversion into a bed, the lower seat unit is swung out to rest in a horizontal position on a hinged strut 37, foldable into the seat unit and the back unit rests horizontally on arm rests 36, pivoted on the ends of a rod 35 and swung down to act as struts, the upper seat unit resting on lugs 20. For support of the back unit, struts may be used and in this case the arms 36 are used for locating a pillow against lateral displacement. According to the Provisional Specification, the back unit may be detachable from the frame or foldable forwardly on to the upper seat unit. Also the lower seat unit may be hinged to the front edge of the base instead of to the upper seat unit.

Patent GB-752996-A (GB)
Title: Method of manufacturing germanium layer crystals
IPC: C30B15/20
Filed: 1954-10-08
Abstract: Single crystals of germanium comprising alternate N and P type layers (as required, e.g. in transistors, photo-transistors and diodes) are made by a process in which the crystal is cultivated from diffrent conductivity-type melts in a selected sequence. The process may be performed using a single crucible with partitions so that individual chambers are formed each taking a different conductivity-type melt. The invention is dependent on the high surface tension of germanium whereby the individual chambers may be filled above the level of the partitions.  In a manufacturing example an H.F. heated crucible has two chambers one of which is filled with an N type melt and the other with a P type melt.  The required crystal is firstly cultivated from the N type melt and after a certain time (e.g. when the crystal is in a stationary state of growth or shows a slight tendency to increase in thickness) the crucible is rotated so that the P type melt in the other chamber comes underneath the crystal and P type cultivation then commences.  The P and N type melts are prepared by adding gallium and antimony respectively to germanium and the amount of impurity may be so chosen that the finished crystal has the same specific resistance (0.1 ohm/cm) in both the N and P type conducting parts.  The process can be arranged to produce any number of different conductivity type layers by changing from one melt to the other, e.g. with a speed of cultivation of 12 cm per hour a crystal of 8 mm diameter and 100 mm. long is obtained by having four single and two double transitions as follows: NP ... PNP ... PN ... NPN ... NP ... PN.

Title: Liquid oxygen converter system for passenger aircraft
Inventor: KUGLER SIMON
IPC: F17C9/02
Filed: 1964-07-17
Abstract: 1,014,259. Respiratory apparatus. BRITISH OXYGEN CO. Ltd. Julv 17. 1964. No. 29228/64. Addition to 940,749. Heading A5T [Also in Divisions F2 and F4]. A liquid oxygen converter system for supplying the passengers and crew of an aircraft, as claimed in the parent Specification, is modified in that the multiport changeover valve is operative when the level of oxygen in the storage vessel falls below a predetermined level to connect the build-up circuit to the line still supplying the crew is a twopositioned valve having three ports 25, 26, 27. When the oxygen is the vessel is above the predetermined level oxygen flows from the bottom of the vessel to the crew through a line (not shown) having a branch line 30 connected to the port 26 where it acts on a bellows 106 to maintain a valve member 105 in a position which interconnects ports 25, 27. Oxygen is therefore also supplied to the passengers, through a line 23 connected to the buildup circuit and to a high level outlet from the vessel. When the oxygen level falls below the high level outlet, the build-up circuit no longer receives oxygen from the line 23 and its pressure falls. The pressure in the port 26 consequently falls and the valve member 105 is moved by a spring 107 to the position shown, wherein oxygen from the port 26 re-pressurizes the build-up circuit and the supply to the passengers though the line 17 is cut off.
