Patent GB-1063688-A (GB)
Title: Improvements in or relating to looms
IPC: D03C5/02
Filed: 1965-09-29
Abstract: The warp threads (2a) are shed to the level of the top of the rearwardly moving seed (3) and are maintained at that level during the reed's movement through rear centre and for part of its beating-up stroke.  Shed change takes place during the latter portion of the beat-up movement.  Shedding is effected by a cam (13) which produces a heald frame movement in accordance with Figure 3 (not shown).  The lower sheet (2b) of warp threads may be shed to the level of the race during the reed's movement.

In a relay plug-and-socket unit, the relay is disposed in a container 1, the casing forming a part of the socket member whilst the plug mounts the terminals and is removable from and insertable into the socket as a whole, complementary key means are provided to ensure that the socket will receive only the correct plug. Thus if a relay socket fails a correct replacement is one which mates with the existing plug. A mounting plate 4 on the container 1 has recesses 4a housing tags 4b formed on spring socket contacts 4c. Bolts 4d pass through holes in the tags and both secure the contacts 4c to the plate 4 and connect them to the relay contacts 2.

The centres of the holes 19-21 lie on straight lines intersecting straight lines passing through the holes 22, 23, and successive pairs of holes are spaced with their centres at increasing distances apart. The increase in distance between successive pairs of holes is in geometric progression. The sides 7, 8 of the housing are provided with cover plates (not shown) for mounting bevel pinions. The spatial arrangement, of the holes 19-23 is such that, in combination with standardized sets of spur, bevel &c. gearing, trains of gears giving different ratios may be arranged within the housing. The ratios thus obtainable are in geometric progression. A number of different-sized housings 1 can be manufactured, related dimensionally in such a way as to permit interchangeability between certain gear-wheels from the standardized sets. In a modification, Figs. 4-6 (not shown), the base surfaces of the housing are so arranged that the gear shafts can be vertical. The widths of the teeth of the various standardized sets of gear-wheels may differ, the arrangement of the gear trains within the housing being such that those gear-wheels transmitting the greatest torque have the widest teeth.

Air is drawn into the building through an inlet 21 and passes over a filter 18 and a heater or cooler 19 before passing through ducts 23 to be distributed to the rooms. In one form the conditioned air is supplied to section 5 of the room unit 2 through a duct 24, cooled by an evaporator 7 and passed into the room by a fan 12. Secondary air is also induced into the unit from the room through inlet 10 by the fan. Air is exhausted from the room by being drawn into section 6 of the unit 2 past condenser 9 and compressor 8 into a duet 32 and exhausted to atmosphere. In another form of the invention conditioned air is supplied to the rooms through ejection ducts 25, and room air is circulated by section 5 of the room unit 2. In a further embodiment of the room unit, induction nozzles may be provided in section 5 of the unit to supply conditioned air and induce a flow of secondary air from the room, thus eliminating the need for a fan in the unit.

[Also in Division C3] Foamed polyethylene sheet is produced from blown tubing extruded through a die 1, 2. The die has an annular passageway comprising a first portion 3 which is substantially parallel sided, e.g. having a width from 0À01-0À05 inch and extending axially more than 0À3 inch from the inlet, a second restricted portion 4, e.g. having a width 0À2-0À9 times the width of portion 3 and extending axially less than 0À2 inch, and a divergent mouth portion 5 whose faces include, e.g. an angle between 10 degrees and 40 degrees and extend axially between 0À05 and 0À2 inch. The first portion 3 may taper slightly in the downstream direction and have an inlet mouth 8. In a second embodiment, Fig. 2 (not shown), the restricted portion occurs further downstream at (12) and the divergent mouth portion imparts a radially outward component of movement to the extrudate. The mouth portion 5 may be cooled by, e.g. air or water, to a temperature below the rest of the die. Duct 7 allows air or other gas access to the extruded tube, which tube may proceed over one or more sizing mandrels, be cooled or heated by currents of air and is flattened by rollers to form lay flat tubing. Take-up rollers may stretch the tubing by as much as a factor of two. The lay flat tubing provides single or double thickness sheeting, whose single thickness may be in the range 0À003-0À25 inch and whose density is preferably less than 5 lbs./cu. ft. Numerous blowing and nucleating agents are mentioned and three examples are given.

Title: Printing telegraph apparatus

Abstract: 1,021,024. Telegraphy. TELETYPE CORPORATION. Dec. 4, 1962 [Dec. 14, 1961], No. 45729/62. Heading H4P. The invention relates to the selection and construction of the electrical contacts in a keyboard-operated printing telegraph transmitter. Depression of a character key 8 actuates codebars 9 as described in Specification 1,021,023, and each code-bar that is moved downwards causes a corresponding lever 10 to move anticlockwise. Arm 12 therefore moves upwards and camming surface 13 pushes the top of spring contact 14 to the right. This spring, in common with the other contact springs, is mounted on an insulating block 31 with its toe 40 contacting a terminal which leads to the out-going line distributer. A spring 41 ensures that the toe 40 contacts terminal 39 and that the head 21 bears against camming surface 13. When a code bar is actuated there is no contact between terminal 52 and the corresponding contact spring. In addition, depression of any character key moves lever 65 to the position shown and initiates one revolution of the distributer, see Specification 1,021,026, so that the code combination is sent over the line, after which lever 65 moves anti-clockwise to move all the contact springs away from contact 52.
