Title: Improvements in or relating to typographical slug casting machines
IPC: B41B11/88
Filed: 1949-09-22
Abstract: 665,943. Type-bar-making machines. MERGENTHALER LINOTYPE CO. Sept. 22, 1949 [Nov. 2, 1948] , No. 24357/49. Class 100 (iii). Metal pumps.-A typographical slug casting machine of the kind known under the Registered Trade Mark "Linotype," comprises a metal pot, a plunger reciprocable therein, an operating lever therefor, a spring for actuating the plunger, a rotatable cam for controlling the operation of the plunger through said lever, a strut connected to the lever and movable to and from active position for supporting the lever against the tension of the spring, and automatic means for operating the strut to release the spring momentarily during each rotation of the cam. The plunger 8 is actuated by a spring 23 through a lever 21 secured to a rock shaft 12 and acting on an arm 16 of a three-armed lever 11 loosely mounted on the shaft. A second arm 10 of the lever 11 actuates the plunger and a third arm 15 carries an anti-friction steel roller 17 tracking on a cam 18 which permits the actuation of the plunger when the roller enters a recess 25. The spring 23 is adjustably anchored by a hook 54 on a rod 53 threaded into a bracket on the machine frame, the adjustable device being accessible from the front of the machine. To relieve the cam 18 of the pressure of the roller 19, which causes excessive wear during that part of the cycle when the plunger is raised, a strut 26 is pivoted to the lever 11 and rests on a stud 28 mounted for vertical adjustment in a supporting plate 30 secured to the machine frame 32 by three clamping bolts 31 accommodated in three adjustable screw bushings 33. The strut is urged to the left by a spring 38 and has a stop shoulder 37 to engage the stud. Just before the recess 25 approaches the roller 17, the latter runs over a raised portion of an anti-wear shoe 45 on the cam, whereupon the strut is raised slightly from the stud. A shoe 42 on the cam then acts on a nose 41 and swings the strut to the right. As the roller moves into the recess, the strut moves down into a slot in the plate 30, and allows the plunger to move downwards. As the roller leaves the recess, the strut rises and moves to the left, and the roller then moves on to a second anti-wear shoe 46, whereupon the strut is slightly raised and engages the stud as the roller moves on to the normal periphery of the cam.

Patent GB-425304-A (GB)
Title: Method and means for reproducing sound from and to recording sound films
IPC: G11B7/00
Filed: 1933-09-04
Abstract: 425,304. Photographic projection printing apparatus. MARTY, R. H. C., 24, Rue Gallet, Sevres, Seines-et-Oise, France. Sept. 4, 1933, No. 24534. Convention date, Sept. 3, 1932. [Class 98 (i)] [See also Group XXXVIII] A sound - film is photographically rerecorded by a method which has for its object the production of a record which when used in the normal manner, reproduces the sounds without change of timbre or pitch but more slowly than the original sounds. The inven. tion is mainly concerned with soundreproduction, the rerecording apparatus being an adaptation of the reproducing apparatus, one form of which is shown in Figs. 2 and 3. In this apparatus, a lamp 4 and preferably a lens (not shown), are placed within a rotary drum 8 formed with slits 9, so that an optical system 5 projects images of the slits at 10, 10<a>, 10<b> which scan the film 2. The light passing through the film falls on a photo-electric cell 7, by which either direct sound-reproduction is effected or apparatus for re-recording on a second film is operated. The film is fed by a sprocket 3 which is driven by a motor 14 through gearing as shown in Fig. 3, which includes a differential gear. This also drives a shaft 15 carrying the drum 8. The gearing is such that the required speed of the light beams relatively to the film 2 is always obtained, irrespectively of the actual rotary speeds of the members 8, 3, which can be varied as desired by means of brakes 20, 21. This the film may be stopped altogether, whilst reproduction is effected from a portion of the film, or it may be moved slowly or at any desired speed. The main feature of the invention is the provision of screens 11, 12, of graded opacity, through which the light beams pass before falling on the film. These screens cause the intensity of each image of a slit 9 to vary progressively, each image increasing in brightness after its appearance on the film, and afterwards fading out during its movement from a position of maximum intensity ; thus the sounds simultaneously reproduced by the beams scanning any one portion of the film are blended. In using this apparatus for rerecording by direct photographic action on a film, the print film passes through the apparatus so that it is affected by the light modulated by transmission through the film 2, the cell 7 being removed.

Title: Improvements in or relating to photographic printing frames
IPC: G03B27/02
Filed: 1950-10-09
Abstract: 689,987. Photographic printing frames. LEITZ GES, E. Oct. 9, 1950 [June 14, 1950], No. 24584/50. Classes 98 (i) and 98 (ii). In a frame comprising a base to which is hinged a masking platen, a device operable by the platen during its opening movement ejects a light-sensitive sheet from its exposure position on the base, while means operable by the closing movement of the platen position correctly for exposure a light-sensitive sheet after it has been dropped on to the base. As shown, a platen 5 having a rectangular aperture is pivoted on a base member 1 and has a depending masking flange which fits within two lateral ledges 4 on the base beneath which the -lateral margins of the printing paper are located, the top and bottom edges of the paper being located by the paper ejecting member 13 and a lever 29 which projects through a gap 27 in the base 1. The platen is held closed on the base by a manually releasable latch 11. As the platen closes, a projection 20b on it moves past a pivoted lever 22 freely movable clockwise while a second projection 20a is followed by a clockwise-urged lever 19 pivoted at 19a which by means of a link 18 moves a lever 17 pivoted at 17a away from a pin 16 on the paper ejector 13. Simultaneously a slide 25 urged by a spring 24 towards the frame hinge follows an arm 23 on the platen so that the paper is moved against the ejector 13 by the clockwise movement of the spring-urged lever 29 which moves below the surface of the base 1 and by the anticlockwise movement of a pivoted lever 26 engaged by the slide. On raising the platen the slide is moved away from the hinge so that the lever 26 falls into the gap 27 in the base and simultaneously the projection 20b cause the lever 22 to raise the lever 21 from out of the notch 13a in the ejector 13 which is moved by the spring 15 to push the print into the receiver 3. Continued raising of the platen allows the projection 20b to pass the lever 22 and the projection 20a to cause the lever 17 to reengage the pin 16, which resets the ejector to the position shown tensioning the spring 15 and also causes the slide 25 to raise the lever 29 against its spring. To facilitate the initial positioning of the light-sensitive sheet, the base may have a black border 1a. Specification 345,503 is referred to.

[Class 18] A toilet roll spindle which may be locked in its brackets 1b, Fig. 3, consists of two plates 5, 6, Fig. 1, of springy metal slidably clamped between the two halves 2 of the roller by bolts 19 passing through slots in the plates, a pin 13 being capable as in Fig. 1 of holding the plates apart or when the plates are telescoped one over the other for engaging a hole 14. Shoulders 11, 12 are provided on the plates to which access is had through an aperture in the roller so that by positioning and twisting a coin the plates may be slid outwards. The roll may then be placed on the roller, the outer ends of the plates slipped into slots in the trunnions 1b and heads 9, 10 pressed inwards so that bushes 7, 8 instead of the plates engage in the trunnions and so that pin 13 engages hole 14. The spindle cannot then be removed until the roll is exhausted. In an alternative the strips are forced apart and slidden by means of a key inserted laterally into the roller. Other means for locking the strips may also be employed.

Title: Improvements in or relating to trihalophenols
Inventor: CARR CHARLES HUGH
IPC: C07C39/32
Filed: 1966-06-02
Abstract: Trihalogen phenols are prepared by continuously treating tetrahalogen benzenes with an alkali-metal hydroxide and an alcohol at 170-220 DEG C. under sufficient pressure to maintain a liquid phase, and treating the crude reaction product with water in an amount sufficient to dissolve a substantial amount of alkali-metal halide formed in the reaction but insufficient to precipitate organic material. The initial reaction mixture comprises 1 mol. of tetrahalogen benzene, 1 to 4 mols. of alkali-metal hydroxide and 6-100 mols. of alcohol, preferably methanol, and the reaction is effected in a series of zones.  The treatment with water is given before the pressure on the reaction mixture is released, and thereafter the excess alcohol is distilled off and the trihalogen phenol recovered from the residue as a phenolate.  An example is given of the manufacture of 2,4,5-trichlorophenol from 1,2,4,5-tetrachlorobenzene. Another alcohol of up to six carbon atoms may be used instead of or in association with methanol.  Apparatus is described.
