Title: Improvements in portable floor cranes
IPC: B66C23/48
Filed: 1920-09-10
Abstract: 167,128. Manley Manufacturing Co., (Assignees of Manley, R. E.). July 27, 1920, [Convention date]. Jib-cranes.-Comprises a design of light portable crane of the kind comprising a superstructure mounted above one of the castings of a triangular base formed by three castings joined together by arms. The present construction comprises a triangulated superstructure formed of lengths of rolled bars of I-section or the like, and a base of which two of the three castings and the connecting bars are also of standard commercial types. The base is V-shaped and is formed by a special casting at the apex riveted to standard I- section rolled metal bars 31 forming the two arms. The rear end of each bar is riveted to a small casting of commercial type carrying a running wheel 36. The third running wheel 48 is swivelled in the front casting. A cross beam 12 of angle-iron rests on the members 31 and is bolted to upstanding flanges in the front casting. The ends of the cross beam project beyond the line of the bars 31, and outwardly-extending stiffening-members 53, 54, riveted at one end to the bars, are bolted to the cross-beam and to an under cross-member 55. Two converging posts 11 of standard angle section are bolted at their lower ends to the cross beam 12, and are joined at their upper ends by a cap 14, thus forming a triangulated crane post. A tension rod 50 is screwed into the front casting on the base and is bolted to the cap 14, thus forming a second triangulated structure with the crane post and the base. A pair of fixed jib-members 18 are mounted on the posts and are braced by tie-bars 20. This arrangement forms a triangulated jib structure. The hoisting-chain passes from a fixed point on a short cross-brace member 24 and thence round pulleys 26, 23, 16 to the winding-gear 28. In one construction of base, the front casting is provided with upstanding flanges forming a triangular tool-box, the rear wall of which is closed by the beam 12.

Title: Improvements in or relating to film sound records
IPC: G11B7/00
Filed: 1939-09-20
Abstract: 532,785. Optically recording and reproducing sound. ELECTRICAL RESEARCH PRODUCTS, Inc. Sept. 20, 1939, No. 26246. Convention date, Sept. 22, 1938. [Class 40 (ii)] In a sound recording system volume compression is applied during recording and the degree of compression is indicated by lateral displacement of the sound record, as shown in Fig. 4. Control of the recorded amplitude is effected either by manual means or electrically, using a rectified part of the microphone output. In each case a record of approximately constant amplitude is produced and a current, whose magnitude is proportional to the degree of compression, is passed to a solenoid to control the longitudinal displacement of a mask, Fig. 5 (not shown), which in turn causes lateral displacement of the recording light beam. The record produced is narrower than the usual sound track in order to accommodate this displacement. In the reproducer an optical wedge, in the form of a suitably graduated mask, is inserted in the light beam so that lateral displacement of the record with respect to this beam may cause a change in the intensity of the light passed to the light-sensitive cell and thus a change in the amplitude of the sound reproduced. For a variable area system of recording, the lateral displacement of the light beam should take place in steps.

Abstract: 637,333. Printing-machines. CHAMPLAIN CO., Inc. Oct. 6, 1947, No. 26815. Convention date, Oct. 23, 1946. [Class 100 (ii)] A rotary gravure printing-machine of the enclosed fountain type is constructed with a printing-cylinder 12 fitted with an adjustable carrier for the ductor 20 and for the ink-supply nozzle 18, the positions of which are interchangeable so as to permit printing in either direction of rotation of the cylinder. Closing of the fountain is effected by the ductor 20, nozzle 18, by flexible bands 230, 232, Fig. 16, secured thereto and extending to the inside of a detachable liner or pan 200 of the fountain 202, and by end seals 242, 244, Fig. 12, secured by clamps 248. To adjust the holder 86 of the ductor 20 for cylinders of different sizes it is mounted at each end in a slide 42, Fig. 2, adapted to be raised and lowered by screws 36 operated by worm gearing 32, 34 from a crank 22, Fig. 1, the ink nozzle being similarly adjustable by mechanism operable by a crank 26. The ductor carrier is also angularly adjustable about a pivot 52 by means of screw- and-nut mechanism actuated by a wheel 24, and the carrier is spring-pressed towards the cylinder. The ductor 20 is reciprocated axially by crank-mechanism, and a fixed sealing strip 238, Fig. 2, is arranged under the ductor, and extends at each side as far as the extreme positions of the ductor 20 to complete the seal. The impression roller 16 is mounted in bearings carried by screws 154, Fig. 1, which can be raised by nuts driven by a motor when it is required to change a cylinder. Normally the screws are depressed to printing-position by levers 148 which press on abutments 156 secured to the screws 154. Adjustable springs 144, or hydraulic pressing devices actuate the levers 148. Feed rollers 128, 130, are carried by the mountings of the printing-cylinder 16, and the web is wound around these, as in Fig. 6, not shown, in such way that raising or lowering of the cylinder 16 does not affect the tension of the web. This arrangement together with the means for changing the position of the ductor and ink nozzle permits of back printing without use of turning bars or re-rolling of a printed web. To remove the roll 12 and fountain 202 to change the roll, a supporting member 254, Fig. 12, is attached to the frame 50, and by means of rollers 256 mounted in the fountain 202 the fountain and roller are moved over tracks 260 connected to the frame members 46 and pass on to tracks supported by the member 254. The tracks 260 are cut away at the position of the wheels in which the fountain is in operative position. The ink outlet 224 is disconnected from the ink reservoir inlet prior to removal, and the driving-means of the printing-roller is also disconnected. The lining 200 can be readily detached from the pan and is formed of stainless steel, which facilitates cleaning. Releasable holding means 252 hold the roller 12 and the fountain in operative position.
