Apparatus for use in making close-up photographic exposures with a photo-flash camera comprises a frame having a first portion delimiting a camera subject area 11 and a second portion having a camera-mounting surface to which a photo-flash camera 24 can be detachably secured e. g by a screw (19) Fig. 1 (not shown, a reflector 22 fixed to the frame and having a diffuse surface 23 thereon to attenuate and reflect camera flash illumination on to the camera-subject area, and a baffle 21 fixed to the frame to prevent camera flash illumination from striking the camera-subject area directly and from being reflected by the reflector directly into the camera. An auxiliary lens 20 is fixed to the frame to adjust the camera focus to the plane containing the camera-subject area. Even illumination of the subject area is acheived by making the angle #, subtended by the reflector at the point B larger than the corresponding angle α at the point A. Fogging when copying flat and specular subjects, e.g. glossy photographic prints is avoided by making the smallest angle of image rays coming from the subject, Y, greater than the largest angle of illuminating rays, X. An embodiment is described in which the frame and baffle are hingedly connected by a pin and slot to a base to provide a collapsible assembly, a handle being removably attached to the frame.

Abstract: 1,228,774. Measuring hardness of rubber electrically. RUBBER & PLASTICS RESEARCH ASSOCIATION OF GREAT BRITAIN. May 6, 1968 [May 12, 1967], No. 22105/67. Heading G1N. Hardness Measurement. Samples 18 of rubber of uniform size are transferred by a pneumatic ram 16 from a magazine 12 to a glass plate 20 which forms the bed of a station where a hardness test in accordance with B.S.S. 903, Part A7, is carried out. Retraction of a pneumatic ram 32 allows a carriage foot 29 to exert a loading of 200 grams/ sq. cm and a part spherical probe 26 to exert a total loading of 30 grams. After 5 seconds retraction of pneumatic ram 36 allows a weight 34 to engage a platform 38 on the probe stem to increase the total loading to 570 grams. At the completion of 30 seconds, the total downward movement of the probe relative the carriage foot is determined by an electrical transducer of which one part 28 is carried by the probe and the other part 30 of which is carried by helically threaded pillars 42 supported from the carriage foot. At the end of the initial 5 second period of the test, a servomotor 44 operating through gearing 46 is employed to rotate the pillars and relatively position parts 28 and 30 of the transducer ready for the measurement of the subsequent movement. Specific Gravity Measurement. On completion of the hardness test, rams 32 and 36 are advanced to raise the foot and probe free of the sample, and thereafter a further ram 48 transfers the sample to a weighing platform 50. A ram 52 raises the platform free of supports 54 and the weight, or specific gravity, since the samples are of uniform volume, is indicated by an electrical load cell 56. Yet a further ram 58 removes the sample in a direction perpendicular to the other movements. Control System. The sequence of operations is controlled automatically by a control system, Fig, 1 (not shown), which includes provision for applying the hardness and specific gravity signals alternately to a common transducer bridge, and thence through an analogue-to-digital converter to a printer for producing a permanent record or means for producing a temporary record. A comparator is provided whereby signals falling outside prescribed limits may cause visual indications and/or audible alarms, and may either stop the apparatus or cause examined samples to be routed to different destinations in accordance with the measured values. Modifications. The hardness and specific gravity stations may be combined in one. The hardness test may be made at three points on the sample, either sequentially by rotating an offcentre sample on to three positions, or simultaneously by having three contact points which are located at the vertices of a triangular plate which is secured to the probe stem at the centre of gravity by a freely pivoting joint.

Abstract: 1,258,945. Anti-skid braking system. KELSEY-HAYES CO. 3 April, 1969 [28 Oct., 1968], No. 17708/69. Heading F2F. An anti-skid fluid pressure braking system comprising a modulating valve assembly 36 actuable in accordance with and in response to an electrical signal produced by an electrical control module 38 receiving information, from sensors 40 associated with the brake drums 14 e.g. through exciter rings 42, of a skid condition has a source of pressurized fluid ancillary to the source of brake actuating fluid, such as a fluid pump driven off the crankshaft or fan belt of a vehicle engine, for operating the valve assembly 36 and a fluid interlocking valve 54 to control the flow of the ancillary fluid from the pump to the valve assembly 36. As shown the pump 48 is a mechanically actuated transmission pump and themodulating valve assembly 36 comprisesa housing 56 denning, an hydraulic fluid chamber 58 and having a cylindrical housing 60 mounted on one end thereof and.provided with a slidable hydraulic piston 62 mechanically linked to piston members 314, 316 in chamber 58. The housing 56 also has an electrically energized solenoid mechanism 64 controlling the communication of a source of vacuum to a diaphragm assembly 66 which in turn is mechanically linked to a fluid valve mechanism 70 controlling the supply of hydraulic fluid from the pump to chamber 58. When the module 38 provides an output indicating a skid condition, solenoid mechanism 64 is energized to allow one side of the diaphragm assembly 66 to be connected to vacuum to actuate valve mechanism 70, block the flow of fluid from the pump 48 and thus allow movement of piston 62 and seat a cheek valve 72 thereby precluding any further application of the master cylinder brake pressure to rear brake cylinders 14, the brake cylinder pressure being relieved by flow of fluid into the increased volume created by movement of piston 62. The wheels are then.free to spin up until the module 38 de-energizes the solenoid mechanism 64 allowing valve 70 to be opened so that piston 62 is moved to its original position and the check valve unseated whereby master cylinder pressure can again be applied. Piston 314 is biased against ancillary fluid pressure by a spring 340 so that the assembly 36 has a "failsafe" characteristic in that if the pressure of the ancillary fluid falls belowa preselected level piston 62 is maintained by the spring in a position allowing normal braking pressures to be applied from the master cylinder.
