Title: Improvements in or relating to photographic stereoscopic camera system
IPC: G03B35/00
Filed: 1953-11-23
Abstract: 749,136. Stereoscopic photography. WARNER BROS. PICTURES, Inc. Nov. 23, 1953 [May 11, 1953], No. 32409/53. Class 97 (1). A stereoscope camera assembly comprises two objectives with perpendicular axes, one having a reflector on the longer conjugate side for deflecting incident light through 90 degrees, the associated cameras having axial and transverse adjustments, one of them having also a rotational adjustment to converge the optical axes. The parts of the embodiment shown are carried on a base-plate 11 provided with tilting and rotational adjustments on a tripod. Simultaneous axial movements of the kinematograph cameras 65, 77, for focusing, are provided by screw-threaded portions 27, 38 of shafts 28, 36 coupled by gearing 33 and provided with knobs 31, 32, 35 each associated with focusing scales provided either on a drum 171 secured to the shaft or a drum 182 driven by epicyclic reduction gearing, a movable index 184 being aligned with the scale required. The screwthreaded portions engage screw-threaded bosses on carriages movable on rails. Intermediate carriages support the cameras and have initial focusing adjustments, that for the camera 77 being operated by a screw 103 and knob 102 and that for the camera 65 by a rack 67 cooperating with a pinion driven by a pinion rotated by either of the knobs 74, 75 which have a reduction gearing between. The initial infinity adjustment is provided by a member 155 by rotating which one of a number of rods of different lengths can be brought into line with the lever 163 of a dial gauge 164. The mounting for the camera 77 comprises two further intermediate carriages whereby the camera may be adjusted laterally, to adjust the interocular separation, by a knob 93 operating through a screw 88, and may be rotated to converge the two optical axes, by gearing 109, 111 operated by a knob 118 associated with a dial unit 125. The objective 145 of this camera partakes of these lateral and rotational movements. The objective 141 of the camera 65 is rigidly secured to the base 11. This objective carries the reflecting prism 142.

Title: Improvements in or relating to automatic electrical apparatus for indicating, measuring and/or giving warning of temperature changes
IPC: G01K1/02
Filed: 1937-11-25
Abstract: 502,711. Electric signalling systems. ELLIOTT BROS. (LONDON), Ltd., SILCOCK & SONS, Ltd., R., FREELAND, F. L., and BROADHEAD, F. G. Nov. 25, 1937, No. 32461. [Class 40 (i)] In a system for indicating, recording and/or giving warning of temperature changes at a number of points, e.g. ships' holds, silos, &c., the points are provided with resistance thermometers (not shown) which are connected to pairs of termimals a<1>, d<1> .... a<50>, d<50> and together with corresponding fixed resistances f<1> ... f<50> form Wheatstone bridge connections with common resistances h, h<1>, h<2>. An indicating or recording instrument (not shown) of the crossed coil type is connected to terminals k ... k<3>, the terminals k<2>, k<3> of one coil being connected across the supply c and the terminals k, k<1> of the other coil to the junction of the resistances h, h<1>, h<2> and the common contact m of a distributer switch having contacts connected respectively to the junctions between the thermometers and the resistances fl ... f<5>. The distributer is driven stepwise through gearing q by a motor p and the arrangement is such that variations of temperature measured by the thermometers are indicated by the common indicator. Records may be taken on a chart by depressing the instrument pointer by a chopper bar periodically operated by an electromagnet connected in the circuit v and operated by the cam-operated contact t. Temperatures outside a predetermined range may be indicated by the operation of one or other of a pair of contacts by the instrument pointer, the contacts being adjustable to determine the limits of the range. The contacts are connected to terminals w and operated by an electromagnet x to stop the motor B and operate an alarm B. Cam-operated contacts l are included in the instrument circuit so as to close the circuit only when the switch arm o engages a distributer contact. A relay C, connected in shunt with the motor, controls green and red indicator lamps G, R. The selector switch may also carry an indicator dial which when the motor is stopped indicates the number of the affected circuit. The condition of a thermometer may be tested for faults by a switch D which when operated short-circuits the resistance h<1> to disturb the balance of the circuit and cause the indicating instrument to provide an indication as to the sound or faulty condition of the thermometer. The distributer may be manually operated by a handle E. The system also is such that alarm indications are given in the event of failure of the supply sources c, u.
