Title: Improvements in timepieces
IPC: G04B37/04
Filed: 1929-11-04
Abstract: 335,427. Weil, J. Nov. 4, 1929. Cases, watch. - An outer secondary casing 1 for a timepiece 5 has an opening closed by a lid in two parts 3 and 4, of which 3 slides under 4 when they uncover the opening. The watch 5 is hinged to the bracket 8 of a base-plate 7 having two vertical flanges 9, Fig. 8, which are cut to form resilient pieces 10. Resting on the latter and pressed up by them are two rods 11 on which slide the lid pieces 3, 4. When a finger flange 12 is moved to withdraw piece 3 downwards, Fig. 1, this flange carries the piece 4 with it. To recover the opening flange 12 is moved up again and lugs 13 on piece 3, Fig. 5, meet shoulders 14 on piece 4, Fig. 4, and carry the latter cut also. The watch carries two cams 15; pressing upwards against these are springs 18. These retain the watch flat in the case but when, pieces 3 and 4 having been moved to uncover the opening, further pressure is put on flange 12, lugs 19 on piece 3, Fig. 5, meet the heels 17 of cams 15 and swing the watch slightly. As soon as the dead centre is passed the springs 18 raise the watch. In a modification, Fig. 12, a spring 23 tends to raise the watch 20 but a locking bar 24 prevents this. When the opening is uncovered. the lugs 19 remove this locking rod. Also the watch, instead of being pivoted as in the above construction, is slidable on a plate 27 so pivoted; as this plate is raised by the spring, the edge of the watch meets cam lugs 29 rigid with baseplate .21, the watch thereby slid upwards along its plate.

Title: Improvements in or relating to optical, or like measuring instruments
IPC: G01J4/04
Filed: 1954-11-23
Abstract: 817,829. Photo-electric measuring apparatus. AITKEN, I. M. E. Nov. 23, 1955 [Nov. 23, 1954], No. 33890/54. Class 40 (3). In a measuring instrument for the determination of physical characteristics of a sample, an initial beam of radiation from source L is divided by means of a system of mirrors M1, M2, M3 into two secondary beams which are thereafter subjected to oppositely phased sinusoidal variations of intensity by the passage through masks K1, K2 having apertures A1, A2 occluded alternately by a rotating disc D formed with peripheral apertures S1, S2, S3, &c. The radiation may comprise visible light, or infra-red or ultra-violet radiation. As applied to absorption measurements, one secondary beam is passed through the sample contained in a tube T whilst the other passes through an adjustable optical wedge W. The emergent beams are combined by a second system of mirrors M4, M5, M6 and impressed on a photo-electric cell P which controls an indicator I through an amplifier A. Inequality in the amplitudes of the two beams causes a variation in the light intensity impinging the photo-electric cell and results in a sinusoidal output at the frequency of the cyclic variation imparted by disc D and of a phase determined by which beam is of greater amplitude. For manual operation, wedge W is adjusted to obtain equality as shown by zero or a minimum indication on indicator I. For automatic operation, the output from amplifier A is applied to a motor to control the position of wedge W, a phase-reference signal tc being provided from the rotating disc, by means of a commutator on the shaft or a photo-electric cell receiving light through the disc, so that the desired direction of movement for the wedge may be determined. The apertures A1, A2 are shaped to produce a sinusoidal variation of light intensity, a practical shape which closely approaches the theoretically correct shape being illustrated in Fig. 5 (not shown). In an alternative arrangement, Fig. 1 (not shown), the two apertures are arranged closely adjacent in a common mask and are exposed alternately through the same slit. In another arrangement, the masks may be disposed at diametrically opposed points on the periphery of the disc which is formed with an odd number of apertures. The assembly of masks and disc may be arranged in the apparatus after the sample. The invention may be applied to polariscopes, saccharimeters, absorptiometers, turbidimeters and colorimeters. As applied to a polariscope of the type described in Specification 540,876, [Group XX], the two secondary beams are polarized in planes at 90 degrees and both passed through the sample under test. The emergent beams are then passed through an analyser (e.g. a Nicol prism) before combination and application to the photo-electric cell.

Abstract: 1,011,388. Electric selective signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 24, 1964 [Sept. 20, 1963], No. 34589/64. Drawings to Specification. Heading G4H. [Also in Division B6] In a print mechanism having a type carrier movable so as to present a sequence of character representing type elements thereon to a print position or positions, some characters occur more frequently than others in the sequence. In the particular embodiment, the printer is of the kind having a type chain (bearing three identical sets of characters) being driven continuously along a row of print hammers which are actuated at differential times in accordance with comparisons between code groups representing characters to be printed read from a core store and the count in a counter fed with clock pulses produced in synchronism with the advance of the type chain. Operation is of the subcycle kind. Each set of characters comprises digits, letters and special characters, each digit occurring four times, once in each quarter of the set, so that if only numbers are to be printed, the time taken to print one line need be only a quarter of the usual time. The clock pulses mentioned above, which occur one per subcycle, are also fed to a three-stage ring to effectively divide the p.r.f. by three, to get one pulse per cycle and the latter pulses are counted until a number corresponding to the necessary line printing time is reached when line spacing takes place. This latter number is set by a data processor which also specifies the characters to be printed. As a modification, characters other than digits may occur more often than the other characters.

On the opposite side of the film is a raised stripe 20 of magnetic sound recording material along one edge, with a raised balance stripe 24 of the same material along the other edge. When the film strip is wound into a roll the stripes 20 and 24 abut against the next over-lying convolution of the roll, as seen in Fig. 4. The roll of film is placed with one end-face, preferably the sound stripe end, lying on a support 46 and a heated platen 48, or a source of ultrasonic energy, applied to the other end. The photographic emulsion layer 16 melts at a lower temperature than the stripe 24, so that the stripe becomes slightly embedded in the emulsion layer, as seen in Fig. 5. This is sufficient to hold the convolutions of the roll together, and prevent axial displacement or clockspringing thereof. The bonding is sufficiently light to be pulled apart easily when the roll is unwound.
