Abstract: 721,937. Endless belt conveyers. CONTINENTAL GUMMI-WERKE AKT.-GES. Nov. 26, 1952 [Nov. 26, 1951], No. 29963/52. Class 78 (1). A tubular elastic conveyer belt is of substantially rectangular cross-section and is provided with at least one longitudinal slit provided with closure means for closing the belt at its slit. As shown, Fig. 1, the belt is divided into an upper part 2 and a lower part 1 provided with reinforcement 3. The two parts are united by continuous ribs 5 engaging in continuous grooves 4. Any number of ribs and/or grooves may be provided in each part. Charge and discharge is effected by closing and opening one or both sides of the belt, by means of rollers, the upper part in the case of only one side being opened being arranged to lie alongside the lower part in inverted position. The two parts may be moved away in opposite directions after discharge as in Fig. 14, the upper part being if desired provided with ribs 12 for assisting vertical conveying, or the upper may be guided in a loop beyond the lower part (or vice versa) this loop being adjustable along the length of the conveyer if desired, Fig. 13, to vary the discharge point into a shoot 10. To facilitate opening and closing of the belt by passing around rollers the outer roller-engaging belt faces may have bevelled portions 19, Fig. 21, such that the stretch of the belt parts in passing outwardly around the rollers causes the groove 4 to open and the rib 5 to be lifted clear of the groove without friction. The groove 4 may be simplified into an undercut lateral side of the lower part so that the upper part fits on the lower part as the lid on a jam jar, bevelled faces 19 being provided on the upper part to prevent friction during opening and closing. The groove 4 may also be opened by providing the opening roller 8, Fig. 26, with a rib 21, or a plain roller may be used and a rib formed on the belt part 1 beneath the groove 4. The belt may be guided by rollers to move with its crosssection vertical so that it may be passed in a tortuous path around a chamber. Guiding of the belt arranged horizontally may be facilitated by providing ribs 13, Fig. 15, on the outer faces of the belt engageable with grooves 14 in guiding rollers. Reinforcements 15 may be provided in the ribs 13. The belt may be formed in one piece with two overlapping upper parts 16, Fig. 16. forming the slit. Alternatively a central slide fastener may be incorporated in the middle of the upper side. A separate cover band may alternatively be used to fasten together the two halves of the upper side.

Title: Safety device for use in locking a wheel chair to a carrier structure
IPC: A61G3/08
Filed: 1972-06-28
Abstract: 1367811 Adjustable sheets H A V JOHANSSON 28 June 1972 [23 July 1971] 30222/72 Heading A4J [Also in Division B7] A wheel chair has a seat slidable on support member which have connecting means adapted for coupling with corresponding support members on another object in order to enable the seat to be transferred to or from the wheel chair. In a preferred embodiment the seat 1 has a bar 2 carrying rollers 3 which rest on a support member 7 secured to the wheel chair frame. In operation a handle 8 is used to adjust the height of the support member 7 carrying a sleeve 21 so that a peg 28 on another piece of furniture may enter the sleeve 21, the peg being held there by a spring-loaded rear latch 22, to displace a bar 10 with locking member 15 against bias of spring 13 to the left. Thus latch 16 may be moved out of engagement with roller bar 2, so that the seat may be rolled on support member 7 on to the other piece of furniture. In so doing a rear part 2' of the bar 2 moves a latch 25 to the position 25' thus securing rear latch 22 against unintentional release. Subsequent to this abutment 6 on bar 2 will force a spring-loaded locking member 32 on the other piece of furniture downwards so that locking hook 30 may release latch 22 and thereby disengage the wheel chair after the seat has been transferred. The member 32 under bias of spring 31 reverts to its upper position where it serves as a stop member for the seat. Corresponding mechanisms are arranged on both sides of the wheel chair and may be interconnected such as by transverse shafts 35, 36 for latches 25 and handles 19 respectively. The seat may be made in one piece from pressed or molded plastics.

Patent GB-674719-A (GB)
Title: Improvements in magnetic compositions
IPC: H01F1/33
Filed: 1950-12-14
Abstract: 674,719. Magnetic compositions. CROWLEY-REPUBLIC STEEL CORPORATION. Dec. 14, 1950 [Feb. 18, 1950], No. 30540/50. Class 38 (ii). A magnetic composition is composed principally of ferromagnetic material containing a mixed ferrite having distributed through it metallic iron in crypto-crystalline form with, optionally, further powdered metallic iron. This composition may be produced by intimately mixing ferric oxide with oxides of metals which modify the electrical and magnetic properties of the composition, e.g. zinc, magnesium, copper and cobalt, nickel, manganese (and possibly chromium), respectively, subjecting the oxide mixture to prefiring treatment at a temperature between 800 and 1200 C., in a reducing atmosphere, grinding the reduced product, acidulating the powder with hydrochloric acid or ferrous chloride, heat-treating between 1100 and 1450 C. in an atmosphere less reducing then the first, and cooling. The final product contains comminuted iron distributed through it, as a result of dissociation of some ferrous oxide into iron and magnetit so the material reverts to magnetic form during cooling, and in addition powdered iron may be added, or produced by reduction of ferrous oxide. Between 50 and 90 per cent but usually not more than 70 per cent of ferric oxide may be used with zinc and nickel oxides in the ratio by weight of between 2: 1 and 1: 1, various proportions being stated. A carbonaceous material such as dextrin, soluble starch, or flour, may be included with the initial mix to reduce the Fe 2 O 3  to FeO. The firing may be done with commercial gas and air in such proportions as provide a suitable reducing atmosphere. In pre-firing, the material, in containers 15 X 10 X 2 inches is heated up for 20 minutes to two hours, retained, preferably at 1050- 1100 C. for 2-6 hours and cooled to room temperature during 3-6 hours. Grinding, completed or partly done before acidulation, may be to a fineness of 1 micron. After the acidulation which promotes rapid sintering and homogenizing, the material is washed until its pH value is about 3, dried, and optionally mixed with a carbonaceous binder, e.g. phenolformaldehyde resins with or without a solvent, which is burnt away at the second firing. The shaped body may be coated with a ceramic material, e.g. of 15 per cent talc and 85 per cent feldspar. The final heating, preferably up to 1400 C., is in an atmosphere slightly less reducing than the first, heating up taking about 4 hours, constant heating about 8 hours and cooling 4 hours. Figures are given showing the improved values of Q, Y and their temperature coefficients of the composition.

Title: Improvements in or relating to shift registers
IPC: G11C19/04
Filed: 1961-08-25
Abstract: 945,525. Shift registers. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 25, 1961 [Aug. 29, 1960], No. 30733/61. Heading G4C. In a shift register comprising two groups of cores of magnetic material having a rectangular hysteresis loop, in which each core of a group is coupled via a unilaterally conductive element with a core of the other group and the latter is connected in like manner to the next-following core of the first group,the cores of each group are coupled with corresponding first and second common conductors connected with an output and an input respectively of an electronic amplifying element, the arrangement being such that the shift pulses may be applied to the cores of both groups at the same time. A shift pulse at the input K momentarily causes the transistors T 1 , T 2  to conduct so that current flows from a battery B 2  via windings V and larger windings W to a battery B1, the overall effect being to reset any set cores of the two groups K11...K13, K21...K23. The action is regenerative so that each transistor is held conductive until all the cores in the associated group have been fully reset. Resetting one of the set cores produces a pulse in its output winding U which is passed by a diode D to the input winding N of the next core so as to set this core. A further input winding is provided for each core of the first group for setting purposes.
