Abstract: 1281236 Laminates PNEUMATIQUES CAOUTCHOUC MANUFACTURE ET PLASTIQUES KLEBER-COLOMBES 24 July 1969 [24 July 1968] 37363/69 Heading B5N [Also in Division E1] An inflatable structural member for, e.g. forming the framework of a tent, comprises two portions of elastic material in which are embedded reinforcing elements arranged so as to impart to these portions different characteristics of elastic extension. Each portion is formed of two superimposed corded layers, the reinforcing elements, viz. wires/cables/strands, of each layer being arranged mutually parallel and the wires in the first layer being symmetrically crossed with those in the second layer, relative to the longitudinal axis of the member, so as to form diamond-shaped arrangements (Fig. 2) the angle formed by the elements of one of the portions being different from the angle formed by the elements of the other portion. As shown, portions A, B, joined-to form an-inflatable tube, are each reinforced with two layers la, 2a and 1b and 2b the elements in portions A and B being at angles Œ35 and Œ75 degrees respectively to said longitudinal direction. When pressurized, the direction of the elements tends to return to their equilibrium position viz. # angle 55 degrees, causing variation in the lengths of the diamond shapes and resulting in portion A contracting and portion B extending. The member thus bends along an arc of a circle, Fig. 5. In another embodiment (Fig. 6) two tubes one formed of portion A and the other of portion B are bonded together along their length and equally pressurized to form the vaulted structure of Fig. 8. The ends of the members may be secured to metal cylinders for ground anchorage.

Title: A process for the production of elastomeric filaments from polyesters containing terminal isocyanate groups
IPC: D01D5/06
Filed: 1962-10-09
Abstract: A composition comprising a solution of a polyester containing terminal isocyanate groups, obtained by reacting polyesters with diisocyanates in a suitable solvent, and 1-5% by weight of a fluoroalkyl ester of a poly-functional aromatic, hydroaromatic, or alicyclic carboxylic acid, is spun into an aqueous leath containing at least 10% of an alkylene polyamine, conducted through a saturated steam atmosphere and then heated in air to 110 to 220 DEG C.  The solution is concentrated by evaporation of solvent to a concentration of 70 to 95% by weight before use. Specified polyesters are the reaction products of polyethylene adipate and p-phenylene- or 4-41-diphenyl methane diisocyanate, and specified solvents include dimethyl formamide, dimethyl acetamide, dimethyl sulphoxide, chlorobenzene, dichlorobenzene and acetone. Fluoroalkyl esters specified include those of pyromellitic acid and camphoric acid.  The esters are compounds of the general formula: <FORM:0960341/C3/1> or <FORM:0960341/C3/2> in which n is a whole number from 4 to 12.

Patent GB-1521703-A (GB)
Title: Hydraulic control system with sequenced hydraulic jacks
IPC: F15B11/20
Filed: 1975-09-17
Abstract: 1521703 Hydraulic control circuits CATERPILLAR TRACTOR CO 17 Sept 1975 [25 Oct 1974] 38210/75 Heading F1P A control system for sequential operation of actuators 23, 27, comprises pilot-operated control valves 12, 13, a pilot selector valve 30 for operating the control valves and a sequence control valve 41 between the pilot valve and the control valves, which directs pilot fluid first to the valve 12 and then to the valve 13 after the actuator 23 has extended a predetermined distance. In operation, when the valve 30 is in the D position and valves 78 and 41 are as shown, pilot fluid passes through liner 37, valve 41 and line 56 to actuate the control valve 12. This directs fluid to the head end of actuator 23 through a line 22. As the actuator 23 extends a cam 81 closes a switch 79 and this operates solenoid valve 78 which communicates pilot fluid through a line 77 to a chamber 76 in valve 41. This moves the spool 42 to the right against a spring 44. Thus, communication between lines 37 and 58 is provided so that the control valve 13 is operated to extend the actuator 27. The valve 30 is now manually moved to the H position. To retract the actuators, the valve 30 is moved to the R position to direct pilot fluid through line 38, valve 41 and line 57 to actuate the valve 13. The latter directs fluid from a line 18 through a line 24 to retract the actuator 27. When the actuator 27 is fully retracted pressure in the line 24 rises, and, through a conduit 73, it lifts a pobbet valve 68. Since the pressure in lines 24, 73 is greater than the pilot pressure in chamber 76 the spool 42 is moved to the left. The line 38 is now connected to line 55 and valve 12 is operated to retract the actuator 23. A restriction 74 prevents a rapid pressure drop in lines 24, 73. When the cam 81 leaves the switch 79 the solenoid valve 78 is deenergized and the spring 44 holds the spool 42 in its left position as shown.

Articles such as components of a razor blade magazine delivered unorientated, are fed in succession to two turning devices rotatable through 180 degrees about axes at right angles to one another, in response to feelers which determine the articles position. Tray-like holders A for the blades are fed by a reciprocating conveyer 11 beneath a feeler 7 into a passage 12 in a first device 3. If the holder is bottom uppermost, the device rotates before the conveyer passes it on to the second device 4 preceded by a feeler 8. This arranges that the holders shall advance open end forward. Similar devices 5, 6 orientate the outer casings B with dispensing finger openings uppermost and open end trailing. A stack of blades is placed in each holder A by means not described and the two components assembled, also by undescribed means. Photo-electric means scanning marks on the articles may be used in lieu of the feelers.

Abstract: 1,086,492. Photographic cameras. R. GRUTER, W. MEIXNER and A. NOLTE [trading as BALDAKAMERAWERK RUDOLF GRUTER KOMM GES]. Sept. 28, 1964 [Oct. 5, 1963], No. 39424/64. Heading G2A. A photographic camera is provided on one side of the camera casing 27 with a built-in flash system pivotable about an axis defined by pivots in top and bottom walls of the casing, the flash system having a reflector adapted to constitute at least a part of a side wall of the casing in a closed position of the system in which respective edges of the reflector parallel to the pivot axis abut adjacent parts of the casing. The reflector housing 28 can be turned from its closed position to one of two operative positions in which it is resiliently held. A contact system for a flash lamp comprises two contact strips 44 disposed on the camera casing 27 above and beneath the housing 28. A series of apertures 45, 46 is provided in each strip 44 and a further aperture 47 is formed in the casing 27. Two locating and contact balls are resiliently urged by spring contacts away from the housing 28 and thus engage any desired pair of apertures in the casing 27. Since the apertures 47 are not formed in the contact strip 44 the electric circuit for the flash lamp is broken when the reflector housing is in the closed position. The camera casing also includes means for adjusting the exposure time to the position of the reflector. A pin 30 anchored to the base of the housing 28 co-operates with a slot 35 in a lever 33 pivotally mounted by a screw 34 to the camera. A slider displaceably mounted on the screw 34 carries a pin which engages a second slot in the lever 33. An extension 39 of the slider is coupled at 40 to an exposuretime adjusting ring. Thus rotation of the reflector will impart an appropriate change to the position of the adjustment ring.
