IPC: E05C9/14
Filed: 1924-11-10
Abstract: 237,775. Cousins, F. Nov. 10, 1924. Multiple fastenings; sliding bolts.-A fastening device for doors of refrigerating plant &c. comprises a bolt or bolts E<2> connected to a disc E rotated by a handle C or M. The disc E carries cam surfaces engaging cam surfaces on a fixed disc I, so that rotation of the disc E causes it to move inwards and forces the ends E<4> of the bolts tightly against bearing plates K on the door frame drawing the door in. A similar arrangement of bolts may be provided on the front of the door to aid in releasing it if it should stick.

Title: Single Lens Reflex Camera
IPC: G03B19/12

Abstract: 1,197,405. Inter-changeable view-finders. NIPPON KOGAKU K. K. June 5, 1968 [June 6, 1967], No.26804/68. Heading G2A. A single lens reflex camera has an interchangeable view-finder which is provided, in its field of view, with a scale carrying values of an exposure factor (e. g. shutter speed, or diaphragm value), an index pointer which inter-locks with means for varying the said exposure factor also being visible against the scale when the finder is mounted on the camera. Fig.1 shows the viewfinder, which comprises a focusing screen 3 carrying the scale 3a, a condenser lens 4 and a spacing member 2, these parts being assembled together between two frame members 1 and 6 which fit one into the other. The unit so formed fits into the bow 13 on the camera body. A pointer 8 is attached to a slide 18 which has a rack and pinion connection to the shutter speed setting knob 14. Thus as the knob is turned, the pointer 8 moves accordingly, and since it projects into box 13 through a slot in the box wall, it is visible in the finder against the scale 3a. Fig. 4 (not shown) is a modification in which the sliding pointer is linked to the diaphragm-setting ring. Figs. 8 and 9 (not shown) are of a further modification of the unit of Fig. 1 adapted to be used with either an eyelevel finder or a waist-level finder. In this case the screen has two scales, one along each edge, one or the other being in use according to which way it is inserted into the finder.

Title: Improvements in or relating to hollow metal propeller blades
IPC: B21D53/78
Filed: 1939-10-02
Abstract: 535,264. Screw propellers. UNITED AIRCRAFT CORPORATION. Oct. 2, 1939, No. 27050. Convention date, Oct. 1, 1938. [Class 114] [Also in Group XXII] A hollow metallic propeller blade having thin walls reinforced by internal webs is built up from a tubular blank 10 and a core member 24 having tines 28, 30, 32, 34. The blank 10 is formed at one end with a flange 14 and the wall thickness of the cylindrical portion 18 is gradually reduced towards the opposite end. The cylindrical portion is then bifurcated as shown in Fig. 2. The core member 24 has a thin portion 26 to form the blade tip, side tines 28, 30, to form the leading and trailing edges of the blade, and tines 32, 34, to form the internal reforcement. The tines 28, 30, are rabbeted on both sides. The core is then inserted within the blank 10 the two arms of which are pressed against the tines and welded thereto. If electric resistance welding is used, strips of asbestos or like heat resisting material are secured along each tine within the blade so as to overlap the joint between these parts and the corresponding portions of the tubular blank, and an electric current is then passed through the structure until the contacting surfaces of the outer member and core member become fused together.

Title: Improvements in or relating to Motion Arresting Devices
Inventor: MELDRUM RAYMOND WALTER
IPC: G05G5/24
Filed: 1967-06-13
Abstract: 1,199,773. Remotely-controlled fastenings. INTERNATIONAL COMPUTERS Ltd. 31 May, 1968 [13 June, 1967], No. 27116/67. Heading E2A. A motion-arresting device comprises a first projection-carrying member 2 relatively moveable with respect to a second member 5, the second member 5 being pivoted about an axis 4 and being provided with a projectionengaging surface 6, means for applying fluid pressure selectively to first and second balls 10, 24 freely moveable within guide channels 8, 9 which balls act on the second member 5 on opposite sides of the axis, the application of pressure to ,the first ball 10 causing the second member 5 to pivot into an operated position in which the projection-engaging surface 6 is operative on one of the projections 3 to arrest motion of the first member 2, and application of pressure to the second ball 24, causing the second member 5 to pivot into a retracted position in which the projection-engaging surface 6 allows motion of the first member 2. As shown, in which a block 1 carrying the member 5 is supported in spaced relation to the member 2, the balls 10, 24 are supported by connecting pieces 11, 25 which are themselves clamped to the block 1 by a connection block 13. The guide channels 8, 9 communicate through respective bores 26 and 12 with chambers 15, 16 in the block 13 and through holes 22 with a chamber 20. A fluid power source 33 is operative at constant pressure upon chamber 20 and a fluid power source 34 is operative to produce fluid flow at a lower pressure through a fluid logie gate 30 to chamber 15 or chamber 16. A control source 35 controls the gate 30. In operation, pressure applied to chamber 16 lifts a valve 18 to the position shown, to seal a vent 19 and the adjacent end of bore 12. Pressure in chamber 20 now raises the ball 10 which pivots the member 5 into arresting engagement with the member 2. Pressure in chamber 15 due to that in chamber 20 is vented through a.port 28. The mechanism is reset by resetting the fluid flow through the gate 30 to pivot the member 5 in a clockwise direction and by moving the member 2- from left to right of the position shown. Where the pressure of the power. source 34 is sufficiently great, the block 13 and pieces 11, 25 may be omitted. The balls 10, 24, 23 and 18, and the members 2 2 and 5 may be made from a plastics material. The invention is applicable to printing apparatus.
