Title: Improvements relating to photographic apparatus
IPC: G03B17/52
Filed: 1965-03-15
Abstract: 1,055,506. Camera. INTERNATIONAL POLAROID CORPORATION. March 15, 1965 [April 2, 1964], No. 10923/65. Heading G2A. A self-processing camera (Fig. 2) comprises first and second sections pivoted at 50. The first section comprises a chamber defined by 14, 16, 48 for a coil of light sensitive film, and a chamber defined by 34, 30, 14 for a coil of image receiving sheet. The two sections co-operate to form a guideway for the light-sensitive film running against rear wall 46 so that it may be exposed through lens 28. The light-sensitive and image receiving sheets are superimposed by pressure rollers 76, 78, housed in first and second sections respectively, whereby on pulling through rupturable containers of processing liquid on the image receiving sheet are broken and the liquid spread between the sheet. The resulting sheets are manually extracted by pulling through opening 64 at the rear of the camera, after opening pivoted cutter bar 142. The extraction of film is arrested when a pair of fingers 130 engaged an appropriately placed pair of holes in the receiving sheet; the cutter bar is then closed, whereby the film may be torn off using serrated edge 152, releasing fingers 130 from the holes in the receiving sheet, thus enabling the film to be moved again. The image-receiving sheet is pushed into contact with fingers 130 by slotted feet 168 supported on support 160 by sections 166, which sections also form guideway for the photo-sensitive sheet. The camera is loaded by turning the second section, which comprises rear wall 46, roller 76 and support member 160, about pivot 50, inserting into the open chambers the two coils of film which are joined at their leading end, and then closing the section so that the film is thus between rollers, 76, 78.

Title: Improvements in or relating to rotary pumps
Inventor: NEELY RICHARD S
IPC: F04C5/00
Filed: 1960-03-29
Abstract: 920,426. Centrifugal pumps; rotary pumps. LORD MANUFACTURING CO. March 29, 1960, No. 11007/60. Classes 110(1) and 110 (2). A rotary pump has a housing having an axial separation between its end walls which varies angularly about the axis of the pump from a maximum to a minimum and back to a maximum, a rotary impeller with angularly spaced flexible blades which bridge the space between the end walls, a tubular sleeve of flexible material which makes sealing engagement with complementary tubular projections on the pump housing which are received in notches in the impeller blades, an inlet communicating with a region of the impeller chamber in which the volume between adjacent blades is increasing, and an outlet communicating with a region of the impeller chamber in which the volume between adjacent blades is decreasing as the impeller is rotated. A metal hub 1 is bonded to a flexible disc 3 having integral flexible impeller blades 4, and tubular sleeves 9, 10 make sealing engagement with recesses 11, 12 in the end walls 5, 6 of the housing 7. Integral tubular projections 13, 14 on the end walls fit over the sleeves 9, 10 and into notches 15, 16 in the impeller blades 4. The impeller blades 4 which extend axially from either side of the disc 3 are axially deflected by the sloping walls 5, 6 so that in operation, at low speeds, liquid enters the pump via the inlet ports 20 in the end walls 5, 6 and is positively displaced from the outlet ports 21, while at higher speeds the liquid pressure on the leading faces of the blades 4 causes them to bend rearwardly and separate from the end walls to cause the pump to function as a centrifugal rather than a positive displacement pump. There is an inlet and outlet port in the housing 7 on each side of the disc 3 so that two different liquids may be pumped simultaneously. By using blades of different axial length on opposite sides of the disc 3 different pumping capacities may be employed. The disc 3 may be cut away between adjacent blades when pumping a single liquid. To reduce stress concentration during operation the impeller blade roots are thickened. Reference has been directed by the Comptroller to Specification 879,019.

Title: Improvements in range-finder sights
IPC: F41G3/06
Filed: 1956-04-11
Abstract: 836,590. Range-finder sights. BEACONING, OPTICAL & PRECISION MATERIALS CO. Ltd. April 11, 1956 [Sept. 21, 1955], No. 11036/56. Class 97(1) [Also in Group XXI] A range-finder sight in which range is determined by an adjustable optical system operating on the coincidence or split-image principle and the required tangent elevation angles of the barrel of the weapon to which the instrument is clamped are provided by an aiming reticle which is moved vertically across the field of vision in correlation with the movement of the adjustable optical system comprises means for additional deviation of one of the two laterally spaced incident light beams so as to accommodate modifications of the ballistic curve of the weapon with changed firing conditions. The adjustable optical system comprises a deviator in the form of contra-rotating wedges or a pivoted plane-parallel plate, and in these cases the beam is additionally deviated so as to modify the original tangent elevation angle of the weapon e=f(R) obtained for a given range R, by an increment # e which is determined by the equation where a is the angle of arrival of the projectile at a range R for initial firing conditions, N is a constant determined by the design parameters of the instrument, and #q q is a quantity indicating the angular amount by which the mechanism of the instrument is reset to provide for a perfect fit at an arbitrarily chosen reference range Ro of the modified ballistic curve of the weapon in changed firing conditions and an approximate fit at other firing ranges. Alternatively, the optical deviator may be a wedge movable along one of the beams of light, and in this case the increment # e is determined by the equation The invention may be applied to the known range-finder shown in Fig. 3 in which the optical deviator comprises optical wedges 7a, 7b, which are contrarotated for ranging purposes by a control knob 9, and in which a vertically moving sighting reticle 4 is mounted by a pivoted lever 5 which is moved by a cam 6 on the frame 8b of the wedge 7b. In order to provide the additional deviation, in accordance with the law first mentioned above, the instrument of Fig. 3 is modified so that as shown in Fig. 4 the cam 6 is rotatably mounted on the frame 8b and is geared at 12 and 10b to a knob 11b, rotation of which moves cam 6 relatively to frame 8b through the required angular displacement A q which can be read off a scale on knob 11b as it moves past a pointer on a disc 11a coupled at 10a to the frame 8b. When knob 9 is rotated to bring the range-finding images into coincidence, cam 6 moves with the frame 8b due to the friction therebetween. In further known forms of range-finder, where the deviator is a pivoted or slidable wedge, operated by a rotatable knob carrying a cam for adjusting the reticle, the required additional deviation is provided by arranging the cam so that it can be rotated relatively to its shaft, (Fig. 7 not shown), through the necessary displacement #q.

Title: Device for storing and transferring information
IPC: H01L27/105
Filed: 1971-07-20
Abstract: 1362692 Semi-conductor devices GENERAL ELECTRIC CO 20 July 1971 [20 July 1970] 11139/71 Heading H1K In a charge-coupled information storage and transfer device conductors 16, 17, 18 (Fig. 1) of an upper set insulatingly overlap adjacent conductors 13, 14, 15 of a lower set so that the depletion regions 19-23 induced in the semiconductor surface beneath the insulating layer 12 where it underlies adjacent conductors can merge under the action of appropriately phased voltage pulses on the conductors to facilitate transfer of minority carriers. The minority carriers may be generated within the semiconductor body 11 by electromagnetic radiation or by injection from a point contact or from a PN junction (24, in Fig. 1), in each case in response to an external information-bearing signal. Various materials are disclosed for the different parts of the device, viz. Si, Ge, GaAs, InSb or CdS for the body 11, silicon dioxide or nitride for the insulation 12 and Mo, W, Si or Al for the conductors 13-18. In one embodiment different materials may be used for the two sets of conductors; e.g. Mo and Al or Mo/Au respectively. Fig. 4 (not shown) illustrates a multichannel shift register in which information is simultaneously transferred along a plurality of parallel channels crossed by two parallel sets of conductive strips corresponding to the conductors 13-18 of Fig. 1. Fig. 5 shows a modification of this in which the conductors 45 of the upper set diagonally cross and recross adjacent conductors 44 of the lower set between adjacent information channels 43 in such a way that the direction of transfer of charges is reversed between adjacent channels (see arrows). The provision of interconnection channels linking adjacent information channels 43 permits charge reaching the down-stream end of one channel 43 to be inserted into the up-stream end of the next channel, allowing a very high storage density to be obtained. A variation serving the same end is partly illustrated in Fig. 7, which shows every second conductor 53b, 53d, 53f of a coplanar set 53a-53f being stepped so as to be situated closer to each of its straight neighbours in turn in successive information channels 51a-51b. A higher level of relatively broad straight conductors (54-54c) Figs. 8, 9 (not shown) overlaps adjacent straight and stepped conductors of the set 53a-53f whenever they lie relatively close together. In this embodiment, as in the last, information travels in opposite directions in adjacent channels. A final modification is illustrated in Fig. 10, in which there are three levels of overlapping conductors 61-63.
