Abstract: 939,165. Still and motion picture cameras. KODAK Ltd. Oct. 3, 1960 [Oct. 2, 1959], No. 33828/60. Class 98 (1). In a camera having an automatic exposure controlling member, a signal movable into and out of the viewfinder is controlled jointly by a cyclically moving member and means movable with the exposure controlling member. In satisfactory light conditions, a flag 42 is held visible in the viewfinder 44 by the diaphragm vane 12 contacting an arm 40 of the lever 36. When vane 12 reaches its maximum aperture position a notch 34 comes opposite arm 40 so that as a cam 50 rotates, driven by a motor operating the shutter and film feed in a kinematograph camera, flag 42 oscillates into and out of the viewfinder. In modifications, notch 34 may be replaced by a projection, or arm 40 and flag 42 may be on the same side of the pivot 38.

Filed: 1967-07-27
Abstract: 1,200,459. Shuttleless looms. MACHINEFABRIEK L. TE STRAKE N.V. 27 July, 1967 [27 July, 1966], No. 34546/67. Heading D1E. In a jet loom, sufficient weft for one pick is fed into two storage chambers 8a, 8b alternately being picked from one whilst the other is being loaded. A tube through which weft is fed at a uniform rate traverses across the mouths of the chambers to enable suction to draw a loop 1a into the chamber 8a and a loop 1c into the chamber 8b; as the weft passes from the first chamber to the second, a clamp 14 closes to grip it. The leading end of the weft is held by a clamp 16, out of which it is being pushed, at the stage shown, by a rod 19a to enable the picking nozzle to project it in to the shed, thereby emptying the chamber 8a. At the end of its stroke, the tube turns about its axis so that its mouth faces to the left; as the tube retracts, it lays the weft in the clamp 16, which also cuts the weft as it grips it, thereby providing a cut end of the loop 1c which is pushed out of the clamp by a rod similar to the rod 19a and projected into the shed by the picking nozzle.

In a voltage regulator of the vibrating contact type a pair of contacts 10 in series with the field winding 15 of a generator are shunted by a winding 18 and are controlled by a winding 11, one contact and one end of the winding 11 being connected to one generator output terminal 14 and the other contact and the other end of the winding 11 being connected together and to the other output terminal 13 over a resistance 12. The average field current tends to decrease as the speed of the generator increases because of the operation of the contacts 10 under the influence of the coil 11. With increasing speed, therefore, the voltage across resistance 12 tends to decrease whereas the voltage across winding 11 tends to increase. The output voltage which is the sum of the voltages across resistance 12 and winding 11 therefore remains substantially constant.

Title: Improvements in devices for measuring and detecting radiation
IPC: G01J5/60
Filed: 1958-11-06
Abstract: 909,514. Radiation detecting. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 6, 1958 [Nov. 6, 1957], No. 35678/58. Class 40 (3). [Also in Group XX] A system for detecting or measuring radiation against a background of interfering radiation comprises two detectors and filters arranged so that one detector receives the wanted radiation together with a particular spectral hand of the interfering radiation while the other detector receives a different band of the interfering radiation, and balancing means to compensate the outputs of the detectors in the absence of the wanted radiation, these being a common filter element which transmits radiation to one detector and reflects radiation to the other. The invention is particularly suited for detecting the infra-red radiation from a body below 200‹ C. (e.g. a railway axle-box) in the presence of solar radiation, in which case the spectral band to be detected lies wholly within the band of unwanted radiation. In Fig. 3b, the whole radiation passes through a glass optical system O which cuts-off all wavelengths longer than 3Á and impinges on a parallel plate of mono- or poly-crystalline germanium L 1  which reflects all wavelengths below 1.9Á, while wavelengths longer than this are partly reflected and partly transmitted. One detector D 1  thus receives radiation in the band 1.9-3Á which contains the wanted radiation. Wavelengths 0-3Á are reflected to the second detector D 2  through a silicon plate L 2  which cuts-off below 1Á and a further silicon plate L 3  which cuts-off above 2.1Á. The outputs of the two detectors (which may be lead sulphide cells) are subtracted from one another at M and amplified at A, the device M being adjusted so that the amplifier output is zero in the absence of the wanted radiation. Provided both A and M are linear devices, the output of A will be proportional to the strength of the wanted radiation. In a modification, L 2  is of transparent plastic and cuts-off above 2.1Á while L 3  is of germanium and cuts-off below 1.9Á. The energy distribution between the reflected and transmitted beams can be improved by covering the plate L 1  with a layer which produces a surface interference effect. If there are various interfering radiators which may vary independently of one another, the system of filters and detectors can be extended to compensate for each one individually, provided that each interfering radiation has a spectrum which overlaps that of the desired radiation or of another interfering radiation already compensated. Instead of measuring the output of amplifier A, this may drive a servomotor to adjust elements in the device M or to interpose a variable diaphragm or variable absorber in front of one of the detectors.

[Also in Divisions E2 and H2] A shaft 34 driven by a reversible electric motor is coupled to a perpendicular output shaft 38 by a crank and connecting link assembly 35 which imparts a variable speed to the output shaft when the shaft 34 is driven at a constant speed, the energization and direction of the motor being controlled by a relay circuit (see Division H2) to oscillate the shaft 34 cyclically at a constant speed between first and second positions whereby the speed of the output shaft between said positions is gradually increased from zero to a maximum and then gradually decreased to zero. A crank 36 secured to the shaft 34 is pivotally connected to one end of a link 37 the other end of which is pivoted to the output shaft 38, and the construction is such that oscillation of the shaft 34 through 180 degrees turns the shaft 38 through 110 degrees. The shaft 34 may also be rotated manually by means of a crank handle 67 on a shaft 66 carrying a bevel gear 68 in mesh with a bevel gear 69 freely rotatable on the shaft 34. An arcuate abutment 70 on the gear 69 is adapted to engage a radial pin 71 extending from the shaft 34. When the shaft 34 is driven by the electric motor it rotates through only 180 degrees so that the pin remains clear of the abutment.
