Title: Improvements in or relating to the refining of fatty materials
IPC: C11B3/00
Filed: 1942-01-14
Abstract: 555,447. Purifying and stabilizing fatty oils and fats. NATIONAL OIL PRODUCTS CO. Jan. 14, 1942, No. 560. Convention date, Jan. 21, 1941. [Class 91] [Also in Group IV] Fatty materials, particularly those containing vitamins A and D, are refined and stabilized by treatment with a solvent and a vegetable meal. Preferably the solvent contains a small amount of a lower aliphatic monocarboxylic acid. Antioxidants are extracted from the meal and undesirable bad-tasting and odoriferous constituents are removed from the fatty material. The latter may be fish-liver oils concentrates prepared therefrom and also vitamin-free fats and oils such as cotton-seed oil, soyabean oil, pea-nut oil, sesame oil and lard. Meals from cotton seed, soyabean, sesame oil, corn-germ, wheat-germ, alfalfa leaf, pea-nuts, rice-bran, rye and barley are mentioned. It is advantageous to deaerate the meal before use and also to add an adsorbent such as an activated earth or carbon. Suitable solvents are hexane, octane, ethylene dichloride, trochlorethylene, carbon tetrachloride, cyclohexane, methylcyclohexane, benzene, acetone and diacetone alcohol, to which may be added acetic, propionic, butyric or lactic acid. In examples, shark-liver oil is refluxed with soyabean, wheat-germ or corngerm meal and acetone containing some acetic acid. Before use the meal and solvent are deaerated by passing nitrogen through the mixture. The mass is then filtered and the solvent removed from the resulting refined liver oil. In a further example, sword-fish liver oil is treated with ethylene dichloride, cottonseed meal and activated carbon.

Title: Improvements in photographic type-composing machines
IPC: B41B21/16
Filed: 1949-11-16
Abstract: 691,763. Photographic type - composing. HIGONNET, R. A. E., and MOYROUD, L. M. Nov. 16, 1949 [March 17, 1949], No. 737/51. Divided out of Specification 29340/49, under which a Specification was laid open to inspection, May 25, 1950. Class 98 (i). An optical system for a photographic typecomposing machine comprises a collimating lens which forms images at infinity of selected characters to be photographically reproduced, the collimated beam being parallel to the plane of a light-sensitive surface on which the images are to be formed, and a focusing lens and reflection means for focusing the images in the plane of the light-sensitive surface, the focusing lens and reflection means being movable in the said direction to effect spacing of successive character images on the said surface. A photographic type-composing machine includes the combination of a collimating lens, means for moving the characters to be projected through a projection position in the focal plane of the collimating lens, an illuminating flash device to project the image of a selected character through the collimating lens when the character is in the projection position, a focusing lens in position to focus the projected light in its focal plane, a reflector in fixed relation to the said focusing lens to reflect the light passing through the focusing lens through a predetermined angle, a support to hold a light-sensitized surface in substantial co-incidence with the focal plane resulting from the said reflection of the light, and means for displacing the focusing lens and reflector relative to the collimating lens, whereby the successive projections in a composed line are in focus upon the sensitized surface irrespective of the relative positions of the two lenses. As shown, a disc D or the like bearing translucent images is movable relative to a stationary collimating lens 1, a focusing lens 2 is movable along the optical axis of lens 1 in a slotted tube 5, and a reflector 3 movable with lens 2 directs the image of a selected character on to a light-sensitive film F located at an optical distance from the lens 2 equal to its focal length. Selected characters are illuminated by a brief flash from a' lamp L at the moment when the selected character is carried by disc D through a projection position in the focal plane of lens 1. Light rays, after passing through lens 1, form a parallel beam which is focused on film F by lens 2 and the reflecting prism 3, mounted together on a carriage 4 which is displaced along tube 5 by a threaded rod driven by a variable escapement mechanism to effect character spacing. Magnification may be varied by replacing lens 1 or lens 2 by a lens of different focal length. Specification 669,531 is referred to.

Patent GB-396292-A (GB)
Title: Improvements in or relating to automatic lathes
IPC: B23B13/00
Filed: 1933-01-11
Abstract: 396,292. Lathes. HAHN, H., HAHN, O., and TESSKY, K., (trading as INDEXWERKE HAHN & KOLB), Esslingen-on- Neckar, Germany. Jan. 11, 1933, No. 894. Convention date, Jan. 20, 1932. Addition to 382,950. [Class 83 (iii).] The bar feed mechanism for an automatic lathe described in the parent Specification is modified to effect the automatic feed of the stock bars from a magazine. The lever 80 controlled by the cam 6 to operate the spool 5 of the feed mechanism is connected to a pawl 210 which at each feed step intermittently rotates a control wheel 201 carrying an adjustable tappet 202. The control wheel 201 is normally prevented from moving backwards under the influence of a coil spring by a locking pawl 213. After a predetermined number of feed steps, chosen so that the end of the bar 8 being worked has passed clear of the bar guide but is not yet exhausted, Fig. 1, the tappet 202 acts through a lever 203 to withdraw a roller 236 from a cam path on a splined clutch member 205 which is then moved forward by a spring 238 into contact with clutch teeth on a continuously driven worm wheel 206. The shaft 204 is rotated through one revolution before the clutch teeth are again disengaged, and during this movement a cam 207 on the shaft 204 acts through a bell-crank lever 208 on a member 209. This causes the pawl 210, and locking pawl 213 to be lifted from the control wheel, which is thereupon returned by its spring. A crank 239 on the shaft 204 rocks a toothed segment 240 engaging a pinion 218 on a wheel 219 constituting one of a pair of wheels connected by an endless rope 242. The rope carries a stop 244 which moves back the plunger 23 and associated parts and raises the weight 29. A cam 222 on the shaft 204 row acts through lever mechanism 223 to withdraw a shutter 224 from the bottom of a stock bar magazine 243 and allow a fresh bar to descend into the bar guide. The segment 240 is then swung back, allowing the plunger 23 to be moved by the weight 29 so that it engages behind the fresh stock bar which then follows up the bar 8, until it is finally caused to enter the chuck and eject the remnant of the bar 8 in the manner described in the parent Specification. In a modification the feed wheel 201 may be replaced by a rack bar which is fed forward by a pawl and returned by a weight or other means.

Title: Apparatus for the reproduction of data
Inventor: KURZ ARTHUR
IPC: G11B7/095
Filed: 1995-05-04
Abstract: Apparatus for the reproduction of data, which can be read contactlessly from a recording medium by means of an optical pick-up device. 
<??>Such apparatuses are equipped with a focus control circuit, in order to focus the light beam picking up the data onto the recording medium, and with a tracking control circuit, in order to be able to guide the light beam on the data tracks. The light beam is reflected from the recording medium onto a photodetector (PD) comprising a plurality of photodiodes (E, F). Because actual photodiodes (E, F) are not completely identical, they give off different photoelectric voltages under the same illumination. Therefore, the control amplifier (TR) of the tracking control circuit operates unsymmetrically. 
<??>In order to bring the operating point of the control amplifier (TR) of the tracking control circuit into the optimum centre position, an offset-compensation voltage is applied to an input of the control amplifier (TR) and varied until the photoelectric voltages of the photodiodes (E, F) from which the track error signal (TE) is obtained are of equal magnitude. 
<??>CD players, video-disc players, draw-disc players, magneto-optical equipment.

Title: Display device provided with fault diagnostic function
Inventor: DAIDOUJI SHIGETOSHI
IPC: G01R31/00
Filed: 1983-01-06
Abstract: PURPOSE:To diagnose easily which subsystem is faulty by providing each subsystem with a function for generating a pseudo signal corresponding to a signal from the subsystem of the preceding stage, when an electric connection between the subsystem is detached. CONSTITUTION:For instance, in case when a subsystem 3 becomes faulty, even if the connection of a subsystem 2 and 3 is detached, a display by a square wave signal from an oscillating circuit 10 is not executed normally. Because a square wave signal outputted from a three-state buffer 9 is sent to a display element 8 through a driving circuit 7 in the same way as a display signal from the subsystem 2. Therefore, unless a normal display is executed in a state that the connection of the subsystem 2 and 3 is detached, it can be decided to be a fault of the subsystem 3. In case when the subsystem 2 is not faulty, when the connection of the subsystem 2 and 3 is detached, a normal display is executed since the subsystem 3 is not faulty. In case when a normal display is executed when the connection of the subsystem 2 and 3 is detached, it can be decided to be a fault of the subsystem 2.
