Title: Improvements in or relating to photographic apparatus
IPC: G03B9/08
Filed: 1926-04-19
Abstract: 250,982. Duda, F. April 20, 1925, [Convention date]. Measuring speed of projectiles. -Apparatus for taking a series of photographs of a quickly-moving object, such as a projectile in flight, comprising two lens systems arranged one behind the other, the first system 2 forming continuously a real image 3 of the object 1 while the second system 4 projects an image 5 of the real image 3 upon a sensitive surface, is provided in or near the plane 6 of the real image with an opaque blade 7 carried by the prong of a tuning-fork 8 and so placed that the blade uncovers the real image 3 when the fork is in the position of rest. On exciting the fork. the image 3 is alternately covered and uncovered, and a corresponding series of images 5 of the moving object 1 is produced extending across the sensitive surface. This surface may be moved transversely to the optic axis if a stepped row of images is desired. The whole apparatus is enclosed in a camera. In a modified form, the tuning-fork carries on each prong a slotted blade, and the exposures take place when the slots register with each other during the vibration of the fork. The speed of the object may be computed from the data obtained.

Title: Process for changing the properties of hair
IPC: A45D7/04
Filed: 1974-03-07
Abstract: 1466622 Setting hair L'OREAL 7 March 1974 [8 March 1973] 10320/74 Heading D1P 10 to 50% of the cystine in living hair (i.e. hair on the head) is converted to lanthionine, the hair being extended by mechanical deformation during the conversion. Lanthionised hair is more elastic in the wet state, so that fewer breakages occur after shampooing or on combing, it retains its set longer after successive wavings, it is more permeable to dye and bleach, and is less soluble in alkali. Preferably the hair is treated with an aqueous composition (gel, cream or solution) having a pH of 10.5 to 13 at a temperature of 25 to 120C for 5 to 60 minutes. The mechanical deformation is achieved by combing or by winding up around curlers or heated rollers. The hair may be covered with a cap during treatment to retain moisture. The pH is produced by calcium lithium sodium or potassium hydroxide. Lanthionisation is assisted by the presence of up to 5 moles/litre of an electrolyte having a neutral oxidation-reduction potential, e.g. sodium or calcium chloride, lithium bromide or sodium potassium or calcium sulphate or up to 3 x 10<SP>-2</SP> moles/litre of an alkali metal or alkaline earth metal sulphide (e.g. S r S) or 10<SP>-3</SP> to 10<SP>-1</SP> moles/litre of an alkali metal or alkaline earth metal sulphite (e.g. Na 2 SO 3 ), up to 3 x 10<SP>-2</SP> moles/litre of cetyl-trimethylammonium bromide or up to 10<SP>-1</SP> moles/litre of a quaternary ammonium hydroxide or up to 1 mole/litre of guanidine carbonate. Hydroxyethyl cellulose, oleyl alcohol, oleic acid, polyoxyethylene glycol and nonylphenol polyethylene ethers may also be present. Lanthionisation is facilitated if the hair is dry before the treating composition is applied. Specification 1466621 describes converting 15 to 70% of the cystine in living hair to lanthionine, the hair not being subject to any extension during the conversion.

Title: Printed circuit mask manufacture

Abstract: 1,270,625. Projection printing. L. T. W. ELECTRONICS Ltd. Dec. 8, 1970 [March 4, 1970], No. 10358/70. Heading G2A. In the production of a mask for use in making printed circuits, there is provided a transparent master mask 4 with a plurality of accurately defined shapes thereon, the master mask 4 being accurately aligned with respect to an optical system (1, 2, 5) Fig. 1 (not shown); and an opaque variable diaphragm 3 defining a plurality of patterned apertures, the diaphragm being locatable so as to select a particular shape from the master mask 4 for reproduction on a photographic base (6), thus only an image of the selected shape is formed on the base (6). Preferably the patterns and shapes are both circular, the master mask 4 having deep yellow concentric annulii 10-13 while the diaphragm apertures each have an internal ring border 15 (14, 16, 17) Fig. 3 (not shown) in a complementary colour such as deep blue. Alternatively the annulii are polarized in one direction while the ring borders are polarized in the opposite directions. In use, the diaphragm 3 is rotated until a hole of the required size is in position. Collimated white light is now shone on the diaphragm and a blue ring is formed on the master mask 4. This ring overlaps the yellow annulus 11, thus the outer perimeter of the spot appearing on the base (6), which may be moved during an exposure, is determined by the inner edge of the yellow annulus 11. In another embodiment, primary and secondary holes are provided in one or more diaphragms, the primary hole illuminating a particular chosen annulus of the master mask, and the secondary ring illuminating most of the centre portion of the image of the ring so chosen, the two illuminations being superposed on the base.

Title: Method of and apparatus for effectively increasing the contrast range of displayingthe results of underwater echo sounding
IPC: G01S7/527
Filed: 1966-03-09
Abstract: 1,136,832. Non-linear circuits. ELECTRO-ACUSTIC G.m.b.H. 9 March, 1966 [29 Nov., 1965], No. 10455/66. Heading G4G. [Also in Division H4] In a system for compressing the amplitude range of echo signals to be displayed or recorded, the echo signals are subjected to a delay and a signal for controlling their attenuation is derived from the same signals, undelayed, when their amplitude exceeds a predetermined value. In the embodiment of Fig. 4, amplified and rectified echo signals are applied to the base of transistor R÷4 and through delay network R2, C2, R3, C3 to the control grid of pentode R÷3. Echo signals of amplitude exceeding a threshold at which they overcome a bias set by potentiometer R8 cause transistor R÷4 to conduct, thereby progressively shunting the signal applied to R÷3 control grid. The output voltage from R÷3, fed to an electrochemical recorder 4a or an oscilloscope, will thus decrease with increasing echo amplitude above the threshold, enabling lowamplitude fish echoes to be recorded in black and the higher amplitude sea-bed echo to be recorded in varying shades of grey indicative of the geological structure of the sea-bed. The attenuation of high amplitude echo signals and degree of blackening of the recorder chart may be adjusted by varying the circuit parameters. The attenuation is emphasised by the reduction in gain of stage R÷3 as its screen grid potential falls when high amplitude echo signals cause grid current to be drawn. The attenuation control may be rendered inoperative as desired or in selected echo-sounding periods by a manuallyoperated or recorder-synchronized switch S, or when recording the initial part (time zero line) of each sounding-period record by applying a positive pulse to the transistor emitter from a recorder-synchronized switch (41) (Fig. 10). In a circuit modification (Fig. 8) resistor R7 is transferred to the transistor collector circuit to provide a steep rate of decrease of recording voltage with echo amplitude above the threshold to a value beyond which the transistor is fully conducting and recording voltage again increases with further increase of echo amplitude. An echo attenuation control similar to that provided by transistor R÷4 may be applied to echo preamplifier 3a.
