Abstract: 1485641 Container handling apparatus; loading station J C POIRIER 14 Aug 1974 [14 Aug 1973] 35880/74 Headings B8Q and B8E Apparatus for setting up a container 49 vertically on a base 1 in conjunction with a trailer 44 having a platform 48 tiltable by a jack 51 comprises a cradle 2 pivotable about stub axles 29, 30 by jacks, not shown, acting on axis lines 31, 32. The container when set up on the base acts as a silo which by opening a trap door in its then lower end can discharge through a rectangular opening 61 into hoppers leading to a discharge conveyer. A trailer 44 with a container in its horizontal transport position is backed towards the base 1 until a pin depending from the end of the chassis 44 fully enters a slot 37 in a plate 36 in which position the pivot axis of the platform 48 is aligned with the axis of the stub axles 29, 30. The jacks of the cradle 2 are now actuated until the cradle is swung to rest on the top edge of the container 49 by its long angle irons 12, 14 in which position it is secured. Simultaneous actuation of the jack 51 and the jacks of the cradle 2, with their hydraulic circuits linked, now pivots the cradle 2 and attached container until they can be secured vertically on the base 1. During the simultaneous operation of the jacks those which are contracting act as a brake particularly in the latter stages of movement. After being set up the container can be released from the platform 48 which can be returned to its horizontal position by the jack 51 so that the trailer can be towed away.

Abstract: 637,857. Colour photography. McGRAW, M., (trading as McGRAW COLORGRAPH CO.). Dec. 11, 1946, No. 36626. Convention date, Dec. 11, 1945. Drawings to Specification. [Class 98 (ii)] At least two imagewise hardened pigmented gelatine tissues are produced by the process known under the Registered Trade Mark " Carbro " from colour-component positive bromide prints, one of the tissues is transferred to an assembly support and developed by dissolving away the relatively soluble portions, the other tissue or tissues is transferred or are successively transferred to the same assembly support in registered superposition on the developed film, the transferred tissue or tissues being developed by dissolving away the relatively soluble portions before superposition of any subsequently transferred tissue. The tissues, which are preferably of the kind described in Specification. 637,920 are transferred from paper temporary supports to dimensionally stable supports, preferably lightly grained flexible plastic sheets having elements which co-operate with elements on the final support to ensure registration of the images, the registering elements being preferably of the pin-and-slot type. When there are three colour-separation negatives, the corresponding bromide prints are produced on similar supports, on which the emulsion is either deposited directly, or is carried on paper with an intervening vinyl acetate resin layer and squeegeed on to the support after soaking in water, the paper and resin being then stripped off and the emulsion dried. Registering means on the negatives co-operate with those on the support if printing is by contact, or registering means on both may co-operate with corresponding means in an enlarger. The registering means on the negative may be holes punched at once when they are held in register, or preformed and determining the positions of the films in the camera. The bromide prints are then produced in the usual way. The tissues, being transferred to their supports, are sensitized and brought into contact with the bromide prints, the supports registering by the means provided, and separated therefrom after the usual time for the chemical action has elapsed. The assembly support is also dimensionally stable with registering means, and carries a gelatine layer. The assembled layers may remain on the assembly support, which may be transparent, or may be transferred together to a final support.

Abstract: 798,865. Generating combustion products under pressure. ARMSTRONG SIDDELEY MOTORS, Ltd. Dec. 6, 1956 [Dec. 22, 1955], No. 36737/55. Class 51 (1). In a combustion system for an engine, of the kind comprising a flame tube disposed within an outer air casing, a ring of openings or ports is disposed in the flame tube for admission of air to the combustion space and an annular, forwardly-facing curved scoop is disposed in the air space between the flame tube and the outer casing to guide air to the admission ports. The space within the scoop is divided circumferentially by a number of axially-directed, radiallyextending splitter struts, each pair of struts defining with the adjacent portion of the scoop a flow passage terminating in an admission port. The engine may be an axial-flow gas turbine engine (particularly of the jet-propulsion type) or a ram jet engine. In the gas turbine engine combustion equipment shown in Fig. 2, an annular flame tube built up of sectional parts 17, 18, 19, 20, 21, 22, 23, 24 is disposed between outer and inner air casing walls 15, 16, the flame tube sections being spaced apart by means of corrugated spacers 25. Air admission ports 28 are provided in the flame tube section 19 and similar ports are provided in the corresponding section 20. The downstream portion of the section 19 is shaped to form a forwardly-facing scoop 31 and struts 33 are disposed beneath the scoop between the upstream and downstream portions of the section 19, the air admission ports 28 being provided between adjacent struts 33 and the two parts of the flame tube section 19. The struts are hollow, being provided adjacent the inlet edge with openings 46 and in the floor portion 36 with openings 47 for flow of cooling air therethrough. The struts are each supported by means of a stud 34 secured to the air casing'15 which engages slidingly in a boss secured within the strut. A baffle 49 is disposed within the air space downstream of the scoop 31 so that cooling air flowing past the scoop does not have its velocity reduced. The scoop 32 associated with the flame tube inner wall section 20 is similarly arranged. In Fig. 6 two axially-spaced rows of air admission openings 62, 63 are provided in the flame tube outer wall section 60 and two air scoops 64, 65 are disposed between the flame tube section and the outer air casing wall, the inlet to the scoop 64 which leads to the openings 62 being upstream of the inlet to the scoop 65 which leads to the openings 63. The inner wall of the passages leading to the openings 63 is afforded by a fairing 66. In a similar embodiment in which the two rows of air admission openings are spaced closer together, the inlets to the two scoops are at the same axial location and the fairing 66 is not necessary. The invention is applied in a similar manner to a tube type of combustion equipment.

Title: Improvements in or relating to time-division multiplex communication systems
IPC: H04Q11/04
Filed: 1963-09-24
Abstract: 1,020,121. Automatic exchange systems. SIEMENS & HALSKE A.G. Sept. 24, 1963 [Sept. 24, 1962], No. 37493/63. Heading H4K. In a time division multiplex exchange system in which the address of the calling and called parties rotate in synchronism in respective circulating memories and in which the address of the called party is inserted into the appropriate memory before the free/busy condition of his line has been determined, the output of the called party memory is inhibited during the pulse phase allotted to the call so that the corresponding speech switch is not operated until the condition of the line has been determined. This is achieved by comparing the addresses in the circulating memories with an address provided by a stepping circuit which furnishes the address of every subscriber in the system on a cyclic bases. If the only coincidence between the address provided by the stepping circuit and that of the called subscriber occurs at the pulse phase (time slot) allotted to the call concerned an associated control circuit determines that the called party is free and so initiates ringing thereat by inserting a suitable pulse into a rotating memory in the control circuit which pulse periodically removes the inhibition at the output of the called-party memory. If the called party address appears at any other pulse phase in either the called or the calling party memory and provided that in the former case the inhibition is removed during said other pulse phase (indicating that the called party is engaged in a call and is not just in the process of being tested in respect of a simultaneous call, about which see later) then this indicates that the called party is busy and so engaged tone is reverted to the caller. A further rotating memory is used to record the fact that the calling party is receiving the engaged tone and the signal in this memory prevents further testing of the called subscriber line during the pulse phase concerned. If at this time the called party becomes free he may take part in a new call to or from any subscriber in the system other than that one who is still receiving engaged tone. In the event of simultaneous calls the party who is allotted the earlier pulse phase in the control cycle takes precedence. The stepping circuit provides an address for at least one complete cycle of control pulses so that the condition of the relevant line may be ascertained during that cycle and any action in respect thereof may be initiated in the succeeding cycle or cycles.
