Title: Improvements in or relating to optical deflection apparatus

Abstract: 1299349 Deflecting light INTERNATIONAL BUSINESS MACHINES CORP 26 March 1970 [5 April 1969] 14655/70 Heading H4F In a light deflector formed of a plurality of stages each comprising an element which deflects an incident light beam in one of two directions depending on its plane of polarization, e.g. a Wollaston prism, and electro-optical means for varying the plane of polarization of the light beam, the position of each deflecting element is unimportant when the deflector is used for a collimated light beam and in conjunction with an objective lens since the final position of the deflected beam in the focal plane of the lens depends only on the angle, and not on the actual position, at which the beam is incident on the lens. In such a case the deflector causes the light source to appear as a selected one of a series of equi-angularly disposed virtual sources at infinity i.e. if the splitting angles of successive prisms form a binary progression. If however it is desired to deflect an image in a plane 16 to a series of equidistant positions in an object plane of a lens 17, the reasoning above does not apply since the source of light is not at infinity and the light from any point of the image diverges and converges before and after the lens respectively and it is necessary to arrange that the final deflected beams 1-8 generate equidistant virtual images in the plane 16. This is done either by modifying the deflection angles of the prisms so that they do not form a true binary series, i.e. coarse adjustment during manufacture, or by varying the distance of each prism from the plane 16 (fine adjustment when setting up), since these two quantities are interdependent. In a preferred embodiment the virtual images 4a, 10a, 13a generated by the beams 4, 10, 13 least deflected from the optical axis after every stage are spaced from the intersection of the optical axis 15 and plane 16 by relative distances corresponding to a binary series. The lens 17 may also be disposed between the deflector W0, W1, W2 and the plane 16. The Specification includes details of how to calculate the desired angles and positions of the prisms W0, W1, W2, including the case when the deflector is immersed in oil.

Title: Improvements in liquid flow control valve apparatus
Inventor: BOWERS ERIC HIDER
IPC: F15B11/22
Filed: 1957-05-10
Abstract: 885,256. Valves. DOWTY HYDRAULIC UNITS Ltd. May 8, 1958 [May 10, 1957], No. 15007/57. Class 135. A liquid-flow dividing device has an inlet 28 and two outlets 19, 21 and when the flow rate into the inlet is small the liquid divides and passes through restrictions 29, 31, one on each side of a partition 8 intermediate a hollow closure member 3, each stream passing via the interior 6, 7 of the closure, annular spaces 16, 17 to the outlets 19, 21, respectively. If one flow, say that through outlet 19, increases the pressure drop across restriction 29 exceeds that across restriction 31 thus causing leftward movement of the closure 3, the end 9 thereof approaching a seat 43 in an end cap 14 thereby adding a further restriction in the flow path to the outlet 19. Since this movement of the closure 3 compresses a preloaded spring 25 a new position of equilibrium obtains in which the pressure on the right of the partition 8 will be greater than that on the left whilst the flow through outlet 21 will be smaller than that through 19. The reverse movement of the closure 3 will occur should the flow through outlet 21 become greater than that through outlet 19. When the flow rate into the inlet 28 increases non-return valves 34, 35 are unseated from flanges 4, 5 on the closure 3 to provide additional paths in parallel with the restrictions 29, 31, each additional path comprising openings 32, 33, and 41, 42, in the flanges and closure member, respectively. Any disparity in the flow to the outlets being corrected by movement of the closure 3 as described above. The valves 34, 35 are loaded by springs 36, 37 that abut circlips attached to the closure 3. The device may be used in an hydraulic power transmission system for a vehicle such as a tractor, the output from an engine-driven variable displacement pump being supplied to the inlet 28 and the outlets 19, 21, each being connected to a motor driving the two groundengaging driving wheels of the tractor.

IPC: F01P7/16
Filed: 1953-06-11
Abstract: 720,330. Regulating. MORRIS MOTORS, Ltd. June 11, 1953 [June 14, 1952], No. 15035/52. Class 7 (6). [Also in Group XIII] An engine cooling system comprises a radiator formed in two sections 2, 3 with separator header tanks, 4, 5, but a common bottom tank 8 and the return pipe 12 for the coolant is connected to the tank 4 through a thermostatically controlled valve 13 and to the tank 5 through a by-pass 7 containing a valve 14 which is linked to the engine throttle valve operating mechanism so that the by-pass 7 remains closed up to a predetermined throttle valve opening, whereby the radiator section 3 remains out of operation until the predetermined throttle opening is exceeded. The operating lever 15 of the valve 14 is actuated by abutments 18, 19 on a rod 17 operated from the throttle valve control pedal 25. When the throttle valve is closed or only open a small amount, the valve 14 cuts off the flow through the section 3 and the liquid is only circulated through the section 2. At a predetermined throttle opening the abutment 18 starts to open the valve 14 and at a certain position it is pulled fully open rapidly by a toggle spring 27 to bring the radiator section 3 into action. On release of the throttle valve, the valve 14 is returned by the abutment 19. The valve 13 remains closed until the coolant reaches a predetermined temperature to restrict the circulation to an amount permitted by a bleed associated therewith. A similar bleed may be associated with the valve 14.
