Abstract: 1437914 Monitoring depth of focus BRAUN AG 24 Jan 1974 [26 Jan 1973] 03310/74 Heading G2A A cinÚ camera has means controlled by the focal length setting ring for a zoom lens and by the intensity of the incident light for indicating when the depth of focus falls below a predetermined value. As shown, the ring 4 which adjusts the focal length of the zoom lens 3 has a cam 5 of varying thickness secured to it close to the camera wall. A vertical slider 7 is kept in abutment with the cam by a spring 13. The upper end of slider 7 has a V-shaped cut-out 8 which moves in front of an opening 2 for admitting light to a photoresistive element 9. Thus the light received by the element 9 varies as ring 4 rotates, and is therefore proportional both to the focal length of the lens and to the light intensity. The photo-element 9 is in circuit with a battery 10, a current discriminating device 11 and a light source which is visible in the viewfinder field. The arrangement is such that the light source glows when the depth of focus falls below a predetermined minimum value. A filter 12 can be pivoted into the light path to adjust the response of the device according to the film sensitivity. In a modified arrangement, Figs. (not shown) 2 and 4, the photo-resistor of an exposure meter circuit has additional circuit elements, including a variable resistor (22) which is fastened on the zoom lens setting ring (24), the light source (26) acting as before.

Title: Improvements in or relating to air conditioning systems
IPC: F24F3/052
Filed: 1959-02-02
Abstract: 869,716. Air-conditioning. ROBERTSON THAIN Ltd. (Robertson Co., H. H.). Feb. 2, 1959, No. 3641/59. Class 137 Relates to an air-conditioning system of the type described in Specification 787,565 having air conduits 12, 14 beneath the floor of a building terminating in hot and cold air-ducts 18, 20 feeding to a sill-box 16, the ducts having dampers 22, 24 rotated in unison by a compressed-air motor 26 controlled by a thermostat 28. According to the invention the dampers are maintained 90 degrees out-of-phase for winter operation, but are moved automatically into phase for summer operation and then move in unison but in opposite directions. The dampers are mounted on spindles 36, 54 coupled together by a differential gear 32 so that movement of the piston 25 in the cylinder 26 rocks the spindle 36, through the link 44, and rocks the spindle 54 in the opposite direction, through the gears 33, 34, 35. The changeover to summer operation is effected by an increase in air-pressure in the line 30 from 10 to 30 lbs. per square inch which actuates a piston 45a in a cylinder 45 to rotate the differential casing 52, through links 46, 48, by 90 degrees. thereafter, the dampers will move iu unison under the action of the cylinder 26, but still in opposite directions. If desired, the damper 22 may be arranged to have a reduced stroke by means of a crank-pin 56 on the spindle 54. and an adjustable abutment 58. The double-link 46, 48 then permits the piston 45a to travel for its full stroke, although the damper is arrested by the abutment 58 (Fig. 7).

Title: Magnetic core data transfer systems
IPC: G11C19/06
Filed: 1962-02-01
Abstract: 939,673. Circuits employing magnetic storage cores. AMP Inc. Feb. 1, 1962 [Feb. 20, 1961], No. 3790/62. Class 40 (9). In a shifting register comprising multi-apertured storage cores 11-14, Fig. 3, each having a clear state when the flux is unidirectional about the main aperture 11M-14M, a set state when a flux is established around the outlet aperture 11T-14T by a signal applied to an input or transfer winding 32, 61, 62, 63, and a primed state when the flux established around the outlet aperture by setting is reversed, transfer of the set state to the next core is effected by pump energization which partially restores the flux about the outlet aperture from the primed to the set state prior to restoration of the core to the clear state. If necessary repeated cycles of priming and pumping may be applied to a single core before it is cleared so as to provide sufficient transfer energy to set the succeeding core, especially in the case when the succeeding core is larger or two or more cores are to be set simultaneously. The register shown in Fig. 3 can shift in either direction depending on the connection made by switch S4 to winding 24 or 56. The cores are brought to the clear state by pulses from sources 16 and 22 which are applied alternately to the clear windings of the odd and even cores. A core is set, primed and pumped in the interval between successive clear pulses, the priming and pumping sources 26, 50 being connected to the switch with opposite polarities. In a modification the pumping pulse source may be replaced by a continuous bias. A second embodiment is described, Fig. 4, having only one direction of shift, the priming and pumping winding 94B threaded through the transmit apertures being energized also by the clear pulses so as to serve as a holding winding as described in Specification 899, 366. In this arrangement the inlet and transfer windings 84, 81, 82, 83, and a further portion 94A of the priming and pump winding are threaded through the main apertures of the cores. A further arrangement, Fig. 5, is described having separate pump and priming windings 126, 114, 116, the pump winding 126 being energized additionally by the clear pulses, and the priming windings 114, 116 being allotted with respective sources 110, 112 to the odd and even cores. Fig. 6 and Fig. 7 (not shown) show how the pump and priming sources 142, 140 are used in conjunction with the last stage 132 of a shifting register 134 to control a single larger or pair of succeeding cores 146, 148.
