Abstract: 369,752. Flash-light photography. JOHNSON, F. G., 182, Haverstock Hill, Hampstead, London. March 28, 1931, No. 9491. [Class 98 (i).] In a shutter release on, or for attachment to, a camera and fitted with a sliding contact switch for igniting the filament in a flash-lamp on the camera, means are provided for controlling with precision the instant of the flash relatively to the initial movement of the shutter. In one construction, Fig. 3, a casing 14 for mounting on the camera 10, is fitted with a slide 15 having a wedge portion 15a which actuates the shutter knob 16. An adjustable contact 25, mounted on an insulated end-block 21 is in circuit with the flash-lamp on the camera through a metallic strip 19 and lead 20. The contact 25 is mounted on a plate 23 threaded on the screw 22 and guided by a fixed rod 24, Fig. 2 (not shown), so as to be set relatively to the slide 15 by the external setting knob 26. The slide 15 may be operated by a flexible release 27, or otherwise, and is normally retracted by the spring 17 housed in a projecting end 15c of the slide 15. In a modification of this construction the slide 15 has a projecting part 15d, Fig. 4 (not shown), which operates the shutter knob. In an alternative construction, Fig. 5, the fitting is adapted to be screwed on to the camera by the end 54a of the cap 31, in lieu of a flexible cable release 56 which screws into the other end cap 34 of the fitting at 55.

Filed: 1959-03-20
Abstract: 842,549. Borehole apparatus. SMITH, R. March 20, 1959, No. 9731/59. Classes 68(1) and 85. A deep well chain saw for cutting radial slots at the bottom of a well bore comprises a saw 171 (Fig. 1) which is lowered into the well on a string of drill tubing to the depth of the well casing 20, which stops short of the bottom of the well. The saw, which is driven by an hydraulic turbine 112, controlled by a valve 109 operated from the surface, can be pivoted (while running) to the horizontal position thus cutting a curved radial slot in the rock strata. The whole apparatus can be lifted to extend the slot vertically. The apparatus is suspended at the surface by a frame which supports the drill tubing and which has means for producing relative movement between the drill tubing and a rod 72 which is connected on to a block 96. The block serves as an abutment for one end of a spring 108 which bears on the hydraulic fluid valve 109. Secured to the block is a rod 120 which is connected through the balanced springs 157 and 158 to a coupling 152. The lower end of the coupling is pivoted to a link 160 which is in turn pivoted to a pair of plates 167. The plates carry the frame on which the chain-saw runs and they pivot about the axis of one of the chain sprockets 160. The sprocket is chain driven from another sprocket which is mounted on the same shaft as a bevel wheel which is driven by a second bevel wheel, connected to the turbine through a universal coupling 145.

[Class 39 (i)] An ink for the identification marking of fabrics comprises an ingredient which, under the action of heat or steam is convertible to a compound which exhibits fluorescence under ultra-violent rays. The ink may comprise an acid salt and a resinous material dissolved in a mixture of water, glycerine and isopropyl alcohol. The resinous material may be a polyvinyl alcohol resin. The acid salt may be the hydrochloride salt of alpha phenyl meta amino benzimidazole or hydrochloride salts of similar compounds. This substance will not be dissolved by dry cleaning solvents, but under the heat and steam of pressing it will be hydrolysed and form the free base. This fluoresces under ultra-violet light and will be dissolved out by the next dry - cleaning operation.

Abstract: 558,751 Aircraft alighting-gear. MARTIN, J., and MARTIN-BAKER AIRCRAFT CO., Ltd. July 15, 1942, No. 9819. [Class 4] The wheel-carrying leg of an oleo shockabsorbing retractable undercarriage for aircraft is strutted in the lowered position by a collapsible radius rod having two hinged arms 6, 7, shown in Fig. 2 in a dead-centre position, the connecting joint being offset from the axis of the strutted radius-rod; the arms are spring- held in the coaxial position when strutting and are also locked by a lock in the knuckle-joint connection of the arms which is first released by means of a cable 5 used for retracting the leg. The lock is shown in section, Fig. 5, a spring plunger 15 being carried in the arm 7 and having a nose 9 engaging in a cavity of the part 6 at the joint. Tension on the cable 5, acting on a pivoted lever 27 and a rod 26, which draws the nose 9. A compression spring 10 acting on a collar 22 sliding on the arm 7 is connected by tie-rods 24 to the arm 6 for urging the two arms 6, 7 towards their co-axial position is further compressed by the further action of the cable and lever 27 upon the collar 22 so that the spring 10 no longer acts upon the arm 6 since the connection between the rods 24 and the arm 6 is a pin-and-slot lost-motion one. The entrance of the nose 9 of the plungar 15 into the cavity in the arm 6 moves a spring-controlled plunger 35 to complete a signal-light circuit.

Patent HK-132596-A (HK)
Title: Digital signal processing
Inventor: LIND LARRY FREDERICK
IPC: G06F1/03
Filed: 1996-07-25
Abstract: A sequence of N sine and/or cosine values, e.g. for Fourier Transforms, quadrature demodulation or test tone generation, is produced by interpolation from a geometrically-spaced table of initial sine values using a first interpolation formula. After being output, each sine value is replaced in the table by a further calculated value, so the sine table size is kept at M = (Log2N)+2 (where N is the number of sine values in the sequence). To avoid round-off errors at widely-spaced interpolations, a second interpolation formula is selectively used in which sine values are interpolated from cosine values. A cosine table is therefore maintained concurrently with the sine table.
