Title: Method of and means for mounting tools or tines or their holders or supports in road scarifiers
IPC: E01C23/12
Filed: 1933-11-10
Abstract: 424,296. Road scarifiers. PRICE, F. C., Silverburn, Albert Square, Bowdon, Cheshire. Nov. 10, 1933, No. 31315. [Class 107] The tool holder of a road scarifier is so mounted as to be capable of horizontal lateral displacement against the action of springs. In the construction shown, two tool holders f are mounted on a shaft d which is mounted in the bearings h of a vertically-adjustable frame c. Springs g are interposed between the two holders and between the holders and the frame c, whereby the tools are capable of independent lateral movement when either tool encounters an obstruction. The shaft is circular in cross-section and is secured against rotation by grub-screws provided in the bearings h. The tool holders are rotatably mounted on the shaft and one formed with machined faces which bear against a skirt c<x> on the frame c, when the machine is in operation. The frame is resiliently suspended by springs e in vertical guides of an outer frame a and is resiliently connected to a structure b<1> which is adapted to be raised and lowered by a handwheel b. In a modification, the shaft d is square in cross-section and the skirt c<1> on the frame c is dispensed with.

Title: A Photolithographic Printing Process
IPC: G03F7/06
Filed: 1967-07-07
Abstract: 1,197,974. Photographic production of printing plates. FUJI SHASHIN FILM K. K. July 7, 1967 [July 11, 1966], No.31517/67. Headings G2C and G2M. Printing plates are produced by imagewise exposing a material comprising a support and at least one hydrophilic silver halide emulsion, developing the element in the presence of a colour coupler and a non-tanning colour developer to form an oleophilic dye image in the exposed areas by reaction of the oxidized developer with the coupler and then applying an oil-based ink to the image. Either or both the developer and coupler may be incorporated in the emulsion or another layer or in the alkaline processing solution. The above process produces negative plates but the invention also relates to producing positive plates. These may be produced if the silver halide emulsion contains a colour developer and is overcoated with a fogged silver halide emulsion as after imagewise exposure and treatment with alkali the non-oxidized developer from the unexposed areas diffuses into the fogged emulsion to form a silver image and the oxidized developer thus produced reacts with the coupler to give an oleophilic image. The coupler may be applied in the alkaline solution, in the fogged layer or in a layer coated over the fogged layer. Alternatively, positive plates may be produced by imagewise exposing a silver emulsion, developing with a colour developer (which may be in the emulsion) washing out the developer and oxidized developer, uniformly exposing or treating the emulsion with a fogging agent such as ethylene diamine, a second colour developer and coupler to produce an oleophilic image in the fogged areas which are inked up. A stopping bath of phosphoric acid and benzyl alcohol is probably used after development and before inking up.

Filed: 1925-12-18
Abstract: 257,150. Douglas, W. D. Dec. 18, 1925. Tone-arms; tone-arm joints; cases. - In a gramophone in which the usual horn is dispensed with, the tone-arm S is supported on a platform 1 through the centre of which the mouth of the tone-arm projects slightly, opening into a sound distributing chamber having lateral walls 4 consisting mainly of fabric. The tone-arm is mounted, in the construction shown in Fig. 1, by providing it with an adjustable collar 11 resting loosely on a ring 10 having a curved bearing face. The hole through which the end of the tone-arm passes is chamfered, so that by adopting this method of mounting, the tone-arm can be tilted considerable when required. Fig. 4 shows an alternative construction in which the tone-arm is pivoted in a bracket 20, which is swivelled in a vertical post. The open end of the tone-arm in this case passes through a curved slot 22 in the platform. A sound-modifying damper at the mouth of the tone-arm consists of a disc and cone of cotton 13 mounted on a wire frame 14. This is bent as shown at 15, Fig. 2, and has a handle 17 for adjusting the position of the damper relatively to the orifice. The cone may be separate from the disc of cotton, and fixed in the mouth of the tone-arm. Specification 257,149 is referred to.
