Title: Therapetic device
IPC: A61M21/00
Filed: 1969-04-02
Abstract: 1309545 Responding to flickering illumination NATIONAL RESEARCH DEVELOPMENT CORP 25 March 1970 [2 April 1969] 17243/69 Heading G1A [Also in Division G2] A therapeutic device comprises a pair of spectacles or the like with means for detecting flickering illuminations in the adjacent environment at a predetermined frequency to which the intended wearer is sensitive, and a secondary source of steady illumination arranged for energization to illuminate the user's eyes in response to detection of said flickering illumination.  In an embodiment a pair of spectacles 5, Fig. 2, for alleviating photo-sensitive epilepsy, comprises a photo-cell 1 and a filter 2 with a power source 3 arranged to detect the above mentioned flickering and to energize two secondary source bulbs 4. The spectacles lens Fig. 3 consists of a photo-sensitive absorptive layer 8, a thin polarized film 9,  orientated to exclude specular reflections from horizontal surfaces, a lens 10 to effect optical correction, and an alluminized reflecting surface 11. The complete spectacles thus act to reduce the apparent contrast between the flickering source and other parts of the visual field of the wearer. In a further embodiment, the temporal peripheral visual field is controlled by side panels containing photo-sensitive absorptive material and having an alluminized reflective surface. In another embodiment the light source and reflector are replaced by photo-emitter diodes (14) Fig. 4 (not shown), enclosed in lenticular capsules.

Title: Transmission systems
IPC: F16H59/46
Filed: 1969-07-07
Abstract: 1310515 Change-speed control CAV Ltd 29 June 1970 [7 July 1969] 34134/69 Headings F2D and F2C In a synchronized-shift motor-vehicle countershaft type change-speed gear control, movement of a manually operated gear-shift lever 23 into an alternative gear selecting position energizes an actuator 26 to partly free, i.e. ease, the main clutch 10 and, further, modifies an engine throttle control 25 whereby a gear establishing signal is supplied from a control unit 22 to electromagnetically operable valves (not shown) controlling a fluid-pressure operated gear-shift servo-motor unit 19 on balanced energization of polarized differential synchronism detectors 20, 21 mounted on the input and output shafts of the gear-gox, the output signals of the detectors 20, 21 being compared in the control unit 25 which produces its signal for gear-shift actuation when the compared signals indicate that the relative speeds between the input and output shafts is zero. As shown, an engine 11, normally controlled by a manually operated fuel control lever 24, drives via the main clutch 10 and constant-mesh sliding dog clutch controlled C.S.G. 16 to the output shaft 13. Assuming the sliding dog clutch 17 on the output shaft 13 is coupled to the input gear 14 for direct drive, when the gear lever 23 is moved to the low gear position the actuator 26 is energized to ease the main clutch 10 through the intermediary of a spring 27 and simultaneously the servo 19 disengages the dog clutch 17 and moves it into the central neutral position. A signal is then passed to the throttle control 25 which increases the engine speed, which increase in speed is transmitted via the clutch 26 to the gear-box and when the relative speed of the dog clutch 17 and low gear 15 are zero the servo 19 effects engagement thereof. Fig. 2 illustrates an alternative form of main clutch, engagement of which is effected by independent nested sets of springs 33, 36 the pressure plate being formed in two parts 32, 33 loosely connected with lostmotion by a lip 37 formed on the outer plate 35, the inner light springs 33 passing through holes in the outer plate 35 to separately load the inner plate 32 and provide a two-stage clutch release, the light springs 33 solely serving to transmit the limited torque when the main clutch is eased during synchronism. Further movement of the outer plate 35 additionally moves the inner plate 32 to fully release the main clutch for starting purposes. In a further alternative clutch arrangement, two driven clutch plates are held in spaced relationship by light springs such that during partial clutch engagement the clutch plates are outwardly urged by the light springs alone into engagement with the driving clutch members to transmit the limited torque, full clutch engagement being effected by the normal clutch springs which compress the driving and driven clutch parts and plates together, thereby compressing and overriding the light springs.

Abstract: 1312336 Fluid-pressure servomotor systems SERCK INDUSTRIES Ltd 6 Sept 1971 [22 Aug 1970] 40541/70 Heading G3P A pair of pressure regulators 14, 15 in parallel with each other and in series with a gas supply conduit 10 are set to provide different regulated values of delivery pressure in a conduit 11 connected to valves 27, 28 opened by a rise in pressure above the lower and higher regulated values, respectively. When the valve 27 opens, fluid flows from the conduit 11 to actuate a spool valve 34 which connects a gas storage cylinder 45 with an actuator 18 for a shut-off valve 16 to stop flow through the regulator 14. The actuator also opens a pilot valve 22 to connect a piston and cylinder 54 to the cylinder 45 to operate a second spool valve 35 controlling an actuator 19 to open a shut-off valve 17 so that the pressure in conduit 11 is now determined by the regulator 15. Operation of the valve 28 causes the positions of the valves 16, 17 to be reversed. Selector valves 31, 48, which are mechanically coupled, enable the roles of the regulators to be reversed. Filters 62, 63 and a reducing valve 65 to charge the cylinder 45 are included in the apparatus.

Abstract: 1318180 Permutation locks LIPS' SLOTENFABRIEKEN NV 10 Dec 1971 57571/71 Heading E2A A permutation lock comprises an assembly of discs (e.g. three), 4, Fig. 1, rotatably mounted on a hollow shaft 45 and rotated successively to align their recesses 1, 2, 3, by a knob 7 via a spindle 6, a driver 9 mounted on the spindle, a driving pin 11 and slidable cams 12 (one only shown) associated with the discs; in the locking position of the lock bolt 15, Fig. 2, the recesses 1, 2, 3, when aligned, lie under the pin 13 of a lock bolt lever 14 pivoted at 25, Fig. 3, to the lock bolt 15 and held up by location of its hook-shaped end 16 on the periphery of driver 9; when the driver 9 is rotated by knob 7 until hook 16 drops into recess 10, and knob 7 is further rotated appropriately, recess 10 entrains hook 16 to withdraw bolt 15 via lever 14; further recesses 3a, 3b are provided in at least one of the discs which will enable the lock to be opened, but alarm elements are associated with these further recesses so that an alarm is given when the lock is so opened. An assembly somewhat as above is stated to be known: the invention is concerned with the alarm provisions. As shown, a switch lever 17, Figs. 2 and 3, is pivoted at 25, has a tooth 18, and is supported in the "bolt-out" position on pin 13 of lever 14. When recess 3 is in use, pin 13 drops into it during unlocking, and movement of bolt 15 to the left rotates the discs via lever 14. Lever 17 is also moved to the left, but is supported now by a piece 19 filling the space between the plates forming the disc, and later by a fixed strip 21, so alarm switch 20 is unaffected. If recess 3b is in use, tooth 18 drops into cavity 23 between the plates, so switch 20 is operated. Recess 3a produces the same result.
