Title: Optical arrangement for scanning machines
IPC: H04N3/04
Filed: 1937-01-06
Abstract: 488,221. Television. RADIOAKT.-GES. D. S. LOEWE. Jan. 6, 1937, No. 408. Convention date, Jan. 10, 1936. [Class 40 (iii)] Lenses 5 in a scanning disc 12 for interlaced scanning are illuminated by parallel, vertically incident light 11, the cross-section of which is of even intensity over the entire scanning area. The scanning-spots 6 projected by the lenses are again projected by a lens 13 on a desired enlarged or other scale on a further area 14. The size of this scanning- area is equal to the size of an image on a kinema film, and the vertical progression of the scanning lines is opposite to, and synchronized with, the advance of the film through the scanned area. The parallel light is produced from an aperture 3 in a diaphragm which is intensely illuminated through lenses 2, 9 and is at the focus of a subsequent lens 10, the exit pupil of which is at least as great as the scanning-area of the disc. Tilted strips 15 or 151 at the edge of the scanned area reflect the incident light back to the scanning lenses, and thus produce on the diaphragm a real image 3<1> of the aperture of the same size as, and to the side of, the aperture. The reflected light is separated by a mirror 16 which deflects it to a synchronizing cell 17 which is in parallel with, and in opposite polarity to, a scanning cell 18, and is connected to a common amplifier 21, as described in Specification 460,709. For reception the apparatus is used with an arc lamp 1 and a Kerr cell. The apparatus may also be used with the cathode-ray tube described in Specification 487,241.

Title: Improvements relating to locking devices
IPC: F16K17/164
Filed: 1945-01-04
Abstract: 584,578. Locking rods. TRIST & CO., Ltd., R., and THOMAS, H. B. Jan. 4, 1945, No. 412. [Class 80 (iii)] [Also in Group XXIX] A uni - directional locking device for an axially moving rod 1, such as a valve rod, comprises a collar 2 with a conical surface 3 on the rod which moves within a fixed sleeve 4 having holes 5 for the reception of balls 6. Surrounding the rod and sleeve is an outer ring or sleeve 7 freely moving under gravity to engage the balls with an inner conical surface. The rod 1 can be moved downwards from the position shown in Fig. 1 to that in Fig. 2, but upward movement is prevented by the conical surface 3 forcing the balls 6 outward into locking engagement with the ring 7. For operation in the reverse direction the conical surface 3 is provided on the lower side of collar 2. For an horizontal arrangement a spring is used to replace the force of gravity on the ring 7. By providing the balls with a certain amount of axial movement in the holes 5 of sleeve 4 the collar 2 on the rod 1 can be dispensed with.

Title: Improvements in and relating to the production of artificial silk
IPC: D01D7/02
Filed: 1926-01-07
Abstract: 268,455. Courtaulds, Ltd., Glover, W. H., and Topham, C. F. Jan. 7, 1926. Spinning machines; spinning machines with twisting- arrangements at delivery; connecting continuously delivered material to the winding- means; spindle apparatus; moistening and sizing. - A dry-spun thread of artificial silk is wound in a centrifugal spinning box, and the end is introduced into the latter by means of a current of air or other gas. Thus, the thread A after passing round a godet B, is led through a guide a<1> to a groove d formed in the down-turned, end of a pipe D, and from this point it is returned to the godet, so forming a loop C; the end of the tube D is immediately above the guide funnel E of a spinning box F, such as that described in Specifioation 23158/00; in order to introduce the thread into the box, the tube D is given a sharp downward movement so as to break the loop and at the same time a current of air is passed through the tube so as to blow the end of the thread down the guide E into the box F. It is convenient to moisten the thread on its way to the spinning- box by passage over a damped brush, and the thread may also be sized as by passage over a moistened surface or through a brush. The cake may be removed bodily from the box preferably after heating for a short time. Alternatively, the thread may be wound out of the box preferably through the funnel E, which is then preferably held stationary with its end opposite the centre of the cake; during winding off, the box F may be held stationary or it may rotate, in which latter case an additional twist may be put on the thread.

Title: Improvements in and relating to the production of polymeric esters
IPC: C08G63/06
Filed: 1949-01-10
Abstract: Copolymeric esters are made by heating together compounds of the general formul  (a) <FORM:0660883/IV (a)/1> and (b) <FORM:0660883/IV (a)/2> wherein n is an integer not less than 2, R and R2 are hydrogen or acyl radicals and R1 and R3 are hydrogen or lower alkyl radicals containing from 1 to 6 carbon atoms, the heating being effected under such conditions that intermolecular interchange between the two compounds takes place.  In a modification, the above copolymer is first formed and then heated with either compound (a) or a polymer obtained by autocondensation of compound (a), the heating being effected under such conditions that intermolecular interchange takes place between the copolymeric ester and compound (a) or its polymer. The condensation is preferably effected at 200-320 DEG  C. and in an atmosphere of nitrogen or by bubbling nitrogen continuously through the reaction mixture, and may be carried out under reduced pressure, particularly during the later stages of the condensation.  Catalysts, e.g. sulphuric acid and p-toluene sulphonic acid, may be added to the reaction mixture before or during the condensation.  In examples: (1) a mixture of p-acetoxybenzoic acid, p - (b  - hydroxyethoxy) - benzoic acid and p-toluene sulphonic acid was heated to 260-280 DEG C. under a stream of nitrogen at atmospheric pressure, and then at 280 DEG  C. under reduced pressure, water and acetic acid being eliminated during the condensation; (2) p - (b  - hydroxyethoxy) - benzoic acid was heated to 280 DEG  C. under a stream of nitrogen at atmospheric pressure and then under reduced pressure.  Para-toluene sulphonic acid was then added and the heating continued under reduced pressure.  This product was then mixed with the product of example (1) and heated at 280 DEG  C. under reduced pressure; (3) is similar to (1) except that higher temperatures were employed.  The molten products were drawn out into fibres which could easily be cold drawn. Para-hydroxy-benzoic acid is another example of compound (b). Specification 604,985 is referred to.

Filed: 1992-01-07
Abstract: PURPOSE:To secure the operability of an employment key which, functions with the simultaneous operations of a shift key, a control key, etc., despite the miniaturization of the employment key by setting its size at the value approximate to a keyboard of a normal size. CONSTITUTION:The key pitch forming a primary part of a keyboard is set at <=15mm in order to reduce the total dimension of a keyboard. However a shift control alternate key which must be simultaneously operated with another key has a size larger than the character keys together with an increased key pitch. Thus the shift control alternate key is not easily operated wrong simultaneously with other keys in a simultaneous operation mode. At the same time, the spatial margin is secured for the character keys adjacent to the alternate key so that they can be operated by two fingers. In such a constitution, the operability is less deteriorated when plural fingers ere used to simultaneously operate the shift control alternate key and the character keys.

Title: Image pickup device
Inventor: TAMURA KYOJI
IPC: H04N5/225
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To control the exposure corresponding to a wide illuminance of an object by using a signal processing means so as to detect object exposure data and allowing a microcomputer to conduct proper exposure via an iris means, a transmittivity variable filter means and an image pickup element. SOLUTION: A change in the lightness of an object is detected from a video signal of a signal detection means 13. Whether or not the exposure state is proper is discriminated based on the detection signal, and when proper, a current exposure control variable is outputted as it is. When not proper, an exposure control parameter is selected and an exposure correction value with respect to each parameter is calculated. A diaphragm mechanism means 2, a transmittivity variable filter means 6, a CDS/AGC means 11 are used to control exposure correction variable with respect to each parameter.  The AGC gain is minimized for the lightness of an object outdoor, the transmittivity variable filter means 6 is fixed to a maximum transmittivity state so as to obtain a control variable of the diaphragm mechanism 2 in response to the detected signal and the diaphragm state is made variable in response to the lightness of the object to control an incident luminous quantity to an image pickup element 9 thereby controlling the incident luminous quantity to the image pickup element for exposure control.
