[Class 138 (i).] A receptacle 1, Figs. 2 and 3, for crockery, cutlery and like utensils, which is adapted to be moved up and down in a close-fitting vessel containing washing water, is of rectangular form and consists of a rigid wire frame with wide-meshed wire-work 1<a>, a flanged tray 9 being attached to its underside. The tray which serves to catch liquid dripping from the utensils is preferably detachable and capable of being used as a cover. The receptacle 1 instead of being made of wire may be of sheet metal formed with large holes close together. Partitions 2<a>, 2<b>, &c., are detachably fitted in the receptacle, their upper frame bars being curved downwardly towards the centre. A further partition 2 has its upper frame bar horizontal, and between this partition and the adjacent wall of the receptacle 1 is a perforated sheet metal contained 5 which is partitioned to form compartments for knives, forks, &c. This container is provided with long handles 7. The tray 9 may be attached to the receptacle 1 by spring clamps 9<a>, Fig. 5, and may be formed with nozzles 9<b> through which jets of water are forced when the receptacle 1 is lowered quickly into the vessel containing water. The vessel may be formed with bulging sides and a wide mouth. In the construction shown in Fig. 6, the sides of the receptacle 1 are provided with horizontal bars 11, 11<a> forming slots to permit the introduction of a horizontal perforated partition 13. More than one such partition may be provided, and each partition may be of several parts. A partition may extend across the top of the receptacle 1. In the construction shown in Fig. 9 a horizontal partition is replaced by a shallow receptacle 15, the base 13<b> of which forms a partition, and the edges 15<a> of which are supported by the edges 1<b> of the receptacle 1. In a further construction shown in Fig. 11, the receptacle 1 has inclined slots 12 for partitions inclined to the horizontal, and has similarly-inclined bars 1<c> which are adjustable.

Abstract: 716,537. Composition fuel. HOUILLERES DU BASSIN DU NORD ET DU PAS-DECALAIS. Oct. 16, 1952 [Jan. 8, 1952], No. 25987/52. Class 50 Coal-pitch agglomerates are hardened and rendered smokeless by subjection to a rapid oxidation followed by a less pronounced oxidation in which the temperature is slightly advanced but not above distillation point, the agglomerates being cooled in an inert atmosphere to not lower than 100‹ C. and finally to room temperature in the air. The first oxidation in an atmosphere of e.g. combustion products or steam with a controlled addition of air or oxygen is effected within the range of 200‹ C.400‹ C. and the second at 230‹ C.- 450‹ C. The temperature to which the agglomerates are cooled in neutral atmosphere depends on the nature of the coal and may be 100‹ C.- 200‹ C., and the final cooling by exposure in thin layers to air may be assisted by water spraymg.

Abstract: 855,415. Packaging-machines. FOOD MACHINERY & CHEMICAL CORPORATION. Aug. 13, 1958 [Aug. 30, 1957], No. 26080/58. Class 94(1). [Also in Group XXXV] In a carton-filling machine, Fig. 1a, a granular product is fed from an hopper 20 via an adjustable gate 30 on to a vibrating conveyer 19. A scale-pan 21 is mounted at a predetermined angle to the horizontal and on a skew with respect to the conveyer and distributes the granular product into feed shoots 23, the movement of which is synchronised with a further conveyer 14 carrying cartons C. Movement of the scale-pan 21, through a balance 50, and an automatic electric control system (see Group XXXV) determines the energisation of a vibrator 18 driving the conveyer 19. A switch 16 stops the vibrator when there are no cartons on the conveyer 14. In a modification, Fig. 6, the vibrator and conveyer 19 are replaced by a moving belt conveyer 219 driven by a motor 242. An adjustable gate 230 has a roller 230b, with projections engaging the granular product, driven by a motor M, the speed of which is controlled by a scale pan 221. The direction of rotation of the motor M is selected by manual switches 255, 257 in dependence on the type of product being fed. A sloping channel, Fig. 5 (not shown), may be interposed between the conveyer and the scale pan 21. The funnels 23 may be scanned by a photo-cell arrangement, Fig. 7 (not shown), for stopping the system when a funnel is clogged. U.S.A. Specification 2,320,581 is referred to.

Abstract: 867,089. Frequency discriminators. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 9, 1957 [Aug. 27, 1956], No. 26136/56. Class 40(5) Microwave frequency is stabilized by a discriminator comprising a waveguide directional coupler 3 to one arm 1 of which a received signal of frequency f 1  and local oscillator frequency f 2  are applied, so that they both pass to a limb 4 terminating in a crystal mixer 6 and circuit 7 tuned to the nominal receiver I.F., and to a limb 5 terminating in a mismatch 8 with dummy load 9. Energy of frequencies f 1 , f 2  reflected from the mismatch 8 (both 90 degrees phase shifted) and energy reflected from the circuit 7 then passes to the fourth limb 2 and to a detector 10 and is amplitude modulated at the tuned frequency (I.F.) of circuit 7 to a depth and phase sense dependent on the magnitude and sense of any frequency error between (f 1 -f a ) and the tuning of circuit 7. A reference voltage equal to that from the mismatch 8 above may then be subtracted from the detected output to give a voltage of polarity varying with the sense of the frequency error, applied as an A.F.C. voltage to the local oscillator to stabilize the I.F. Specification 820,205 is referred to.

Title: Improvements in methods of registering negative or positive films in kinematograph cameras, printing or perforating apparatus
IPC: G03B15/08
Filed: 1924-11-06
Abstract: 233,991. Thornton, J. E. Nov. 6, 1924. Colour photography.-A method of registering a negative or positive film carrying a series of groups of component images in a camera, printing-apparatus or assembling machine consists in employing a single registration hole on the film for each group of component images, which is centrally disposed with respect to the group in the longitudinal direction, and preferably also in the transverse direction, of the film, and is adapted to co-operate with a single registration peg on the camera, printing-apparatus, &c. The registration holes are separate from the usual traction holes, which in the case of a positive film are preferably not punched until the film is completed. The method may be applied to either single or double width films. In the case of positive films produced by printing the component images side by side on double-width thin material which is then slit longitudinally into two component strips which are cemented together in superimposition, two adjacent holes are employed for each group of component images, one in each half of the double width, and so placed that the two holes register with each other in the finished film. These holes co-operate with a registration claw having two pegs. The Specification describes the application of the method in the production of two-colour films according to the Specifications 213,647, 213,866, 214.934, in the production of three-colour or four-colour films according to Specifications 224,569, 224,570, 224,571, 224,572, 224,573, 230,965, 231,030, 231,058, 233,990, and 238,688, and in the production of built-up monochrome films according to Specification 227,900.
