Title: Pneumatic holding device
IPC: F15B15/20
Filed: 1973-06-12
Abstract: 1390576 Actuators M MAYER 12 June 1973 [16 June 1972] 27844/73 Heading F1D [Also in Division F2] A pneumatic holding device, Fig. 1, comprises two cylinders 16, 20 arranged so that when compressed air is supplied through a hole 60 the cylinder 16 and a piston 18 attached thereto are extended until a sensor pin 52 abuts a solid object to be held. This lifts a valve 32 from its seat and allows pressure fluid to reach the underside of piston 18 via radial holes 36, annular passage 38 and bores 40. Due to its larger area, the piston 18 exerts a large holding force. In Fig. 2, compressed air is admitted through a hole 23 and passes through holes 15 to the underside of piston 18. Because of the differential effect piston 18 and cylinder 14 move downwards until a sensor pin 52 abuts a hard surface. This raises a valve 19 from its seat so that the underside of piston 18 is vented through an annular passage 33 and holes 35. Simultaneously valve 17 closes holes 15 so that the underside of piston 18 is acted on by the pressure fluid and so exerts its full force. In both embodiments several sensor pins may be provided all of which must be operated before full pressure is produced. If the sensor pin abuts a soft surface, e.g. an operators hand, full pressure is not produced because the relevant valve is not opened. (For Figure see next page)

Abstract: 224,088. Rostaing, P. Nov. 6, 1923. Chimneys; securing chimneys to galleries; chimney galleries.-In a lamp chimney the glass body part 10, which is preferably of truncated conical shape, is held between a surmounted metal part 14 and a metal mounting surrounding the burner by means of rings 8, 12 carrying heat-insulating packings 9, 11, which may be of asbestos or of fine bronze or other metallic webbing. The rings 8, 12 are carried by the flange parts 4, 15 of steel sleeves 5, 13 connected by short riveted rods 7, 17 to sleeves 6, 16 which are secured together by rods 18 having nuts 19, 22 at their ends and passing through wide apertures 20, 21 in the parts 4, 15. Secured between the ring 8 and the flange 4 is the flange 3 of an elastic socket 2 by means of which the chimney is mounted on the burner cone 1, the flange 3 bearing against a rim 23 whilst the sleeve 5, which is perforated as at 5<1>, bears against a rim 24, the whole being fixed in position by means of a milled-headed screw 25 screwed into the sleeve 5 and bearing against the burner. The annular partition 9<a> is supported by upright or inwardly inclined rods 16a connected either with a ring 17<a> secured between the socket 2 and the ring 8, as shown in Fig. 3, or by means of lugs 28 on the ring 8, as shown in Fig. 6, or by means of three flexible projections 30 having rounded heads 31 bearing against the burner cone 1 so as to ensure correct centering of the partition 9<a> with respect to the flame from the wick, as shown in Fig. 8. When the last arrangement is used, and in order to prevent air passing between the partition 9<a> and the glass 10, a cylindrical or truncated conicalshaped transparent element 32 of mica or glass having at its ends metallic rings 33, 34 is arranged between the partition 9<a> and the packing 9. Instead of the ring 33, a ring 35, Fig. 10, may be secured to the top of the element 32 to hide the partition 9<a>, and the element 32 may be reinforced by a metallic trellis 36 of large mesh either inside or outside or embedded in the glass itself.

Title: Structure for resisting projectiles
Inventor: HARRIS LEIGHTON RICHARD
IPC: F41H5/04
Filed: 1964-07-07
Abstract: 1,260,111. Laminates. BRISTOL AEROPLANE PLASTICS Ltd. 7 July, 1965 [7 July, 1964], No. 28042/64. Heading B5N. [Also in Division F3]  A sheet material resistant to projectiles consists of a backing and a facing, the backing including fibrous material in the form of a closely textured layer and the facing including ceramic material having a diamond hardness number exceeding 700, arranged to form at least one substantially continuous barrier layer, and secured to the backing by fibre-reinforced synthetic resin. The ceramic material may be in pieces arranged close together and a variety of shapes of pieces may be used, e.g. flat plates arranged closely edge to edge, cylinder rods or tubes arranged closely side by side, rods having an arcuate concave-convex cross-section with a convex side of one rod fitting into a concave side of the next, semi-cylindrical rods or tubes laid side by side with their flat faces in a common plane and directed away from the exposed face of the armour, and balls or natural pebbles packed close together. The effect of the ceramic pieces is not only to resist a projectile but to deflect it and shatter it. Resistance to further penetration by the fragments of the projectile is provided by the backing. Advantageously the fibrous material of the backing is embedded in synthetic resin. If the sheet must not only act as armour but also as part of a load-bearing structure, then preferably the fibrous material of the backing is impregnated with a first resin and the rigid pieces are secured to one another and to the backing by a second resin, the first resin being stronger but less flexible than the second resin. The resistance to fragments may be assisted by using a second layer of rigid pieces spaced from the first layer by further fibre-reinforced resin. Damage to the sheet material may be readily repaired by filling a hole cavity with ceramic balls in a dough of glass fibre and resin, and covering with a ceramic plate. The backing is suitably formed from frame-wound rovings of glass fibre pre-impregnated with a polyester or epoxy resin. A suitable resin for bonding the rigid pieces to the backing is an epoxy resin. A ceramic containing at least 95% by wt. alumina, is preferred. The examples described include light armour for use in aircraft to resist 0À3 in. calibre ball bullets and armour to resist 0À3 in. calibre armour-piercing bullets and 40 mm. calibre armour-piercing shells.

Abstract: 712,085. Valves. UNITED AIRCRAFT PRODUCTS, Inc. Nov. 13, 1952 [Nov. 19, 1951], No. 28651/52. Class 135. [Also in Group XXXIV] An oil tank assembly, e.g. for an engine lubricating system, comprises a housing having an inlet chamber 33 with an outlet 41, 18 leading to the top of the tank 16 and an outlet 43, 19 leading to a hopper 21 bye-passing the tank, controlled alternately by control means, i.e. a valve 56 actuated by, e.g., a thermal element 82 and an outlet chamber 34 with an inlet 45 from the bottom of the tank controlled by a valve 58 connected to the valve 56 and an inlet 46 from the hopper. When circulating pumps create a pressure difference between the chambers a sleeve valve 58 is held by pressure acting on the plunger 66 via opening 60 against a spring 74 and a housing stop 73, and cold oil passes from the engine sump to chamber 33, through valve 56 to outlet 43, 19, and through the hopper to chamber 34 and back to the engine. When the oil is hot, the thermal element moves the connected valves 56, 58 so that oil passes through ports 61, 62, grooves 49, 51 and outlet 41, 18 to the reservoir and from there through port 45, ports 63, 64 in valve 58 and port 69 in valve 68 to the chamber 34. When cold diluent is introduced into the oil via a pipe 27, prior to stopping the engine, it cools the thermal element by flowing via passages 91, 92 and chamber 93 so that the connected valves are moved to the position shown in Fig. 2, and the diluted oil bye-passes the reservoir. The pumps are now stopped and the spring 74 moves the valve 68 to the left to abut the part 63 of the valve 58 and close the ports 63, 64 in all positions of the valve 58 so that the diluted oil cannot enter the reservoir.
