Title: Improvements relating to holographic apparatus
Inventor: ACKROYD JOHN
IPC: G03H1/00
Filed: 1969-01-17
Abstract: 1,248,566. Halography. BRITISH AIRCRAFT CORP. Ltd. 10 Oct., 1969 [30 Oct., 1968; 17 Jan., 1969], Nos. 51350/67 and 51540/68. Heading C4S. [Also in Division G2] Holographic camera apparatus comprises within a housing 11, a laser 10, a shutter 12, a beam splitter 13, to form an object beam 15 and a reference beam 14, an object 16 and a photographic plate 19 to receive both object and reference beams, a narrow band filter, having a band width equal to that from laser 10, being positioned over the photographic medium. The narrow band filter prevents clogging of the photographic medium by extraneous light. The reference beam 14 passes a density filter and then is reflected by a series of opposed prisms 20, 21. The prisms 21 are mounted for movement toward or away from prism 20 to give an adjustable path length for the reference beam. The photographic film 30, Fig. 2 (not shown), which may be a slide or reel for other medium such as photochromic glass) is held in a frame and underlies the narrow band filter (34). A secondary shutter (36) synchronized with shutter 12 is also located in front of filter 34. When the blind is in position a trip switch 38 actuates the primary shutter 12. To record holograms of larger objects the two adjacent sides of the housing which normally enclose an object 16 are opened outwardly and mirror 16 adjusted accordingly. To compensate for the increased object path length prisms 21 are moved away from prisms 20 to increase the reference beam path length. By pulsing the laser 10 multiple exposure can be made. In this case either the photographic film can be moved or the angle of the reference beam changed for each exposure. The pulsed exposure has particular application in studying stress patterns and vibrating objects. To ensure that the illumination from both the reference and object beams is equal, a photo-cell or grease-spot device 26 is incorporated with the film holder to control the light from the two beams.

Abstract: 1382261 Control of D.C. motors L SEYMOUR 26 Jan 1973 [6 Nov 1971] 51685/71 Heading H2J Intermittent operation, of the; windscreen wipers 4 of a vehicle is provided by the circuit shown, in which contacts 1, 2 are mounted'on the inside of the windscreen 3 which, when dry, produces a capacity value between the contacts to prevent signals applied to contact 1 being received by contact 2, the presence of water on the windscreen changing the capacity to produce at contact 2 a signal which is applied via a transistor amplifier 8, 10 to fire a thyristor 15 and so energize the wiper motor 16. Subsequent closure of the wiper-actuated switch 5 provides energization of the motor for one wiper cycle, removes the supply voltage from amplifier 8, 10 to isolate thyristor 15 from contact 2 and shunts the thyristor to cause it to turn off, further firing occurring when switch 5 opens if sufficient water is still present on the windscreen. Contact 1 may be fed with pulses from the vehicle ignition circuit or from a separate generator, suitable screening and filtering arrangements being provided. Protective diodes 12, 13, 14, 17 are provided for the thyristor 15 and the voltage supply to the amplifier, which supply may be regulated by a Zener diode to stabilize the amplifier current gain.

Abstract: 1,246,331. Hydraulic presses. PACIFIC PRESS & SHEAR CORP. 1 Nov., 1968 [10 April, 1968], No. 51959/68. Heading B5F. [Also in Division B3]  An hydraulic press, e.g. a press brake is provided with means for determining the end of the work stroke of a press ram 1, and timing means responsive to the arrival of the press ram 1 at the end of its work stroke for determining the extent of the return stroke of the ram. Means are also provided for adjustably dividing the work stroke into a fast initial portion and a slow final portion. The timing means and dividing means include adjustable rheostats (197, 199), Fig. 3 (not shown), these rheostats being adjustable simultaneously or independent of each other. As shown in Fig. 1, the ram 1 is reciprocated by two hydraulic motors 3, 5 supplied by pumps 11, 13. For the fast approach stroke fluid from the underside of the pistons 9 supplements the supply from the pumps 11, 13 to the upper parts of the cylinders 7. At a point in the work stroke determined by a timer (169) solenoid windings 89 are de-energized and cause valve assemblies 85 to open and connect lines 19 to a tank. Rapid advance of the ram 1 is thus converted to normal speed since liquid from the undersides of the pistons 9 is no longer supplied to the motors 3, 5.
