Title: Improvements in or relating to preparing seeds with coatings of a seed-treating agent
IPC: A01C1/06
Filed: 1962-12-11
Abstract: 996,373. Coating seeds; medicated bird seed. HARTZ MOUNTAIN PRODUCTS CORPORATION. Dec. 11, 1962, No. 46749/62. Headings A2B and A2Q. [Also in Division F4] In coating seeds without hulls or hulled seeds with a seed-treating agent particularly an antibiotic, a dried layer of the agent is formed on an outer shell of each seed surrounding its inner core and keyed to the outer shell, as by intrusion into fissures or scarified indents formed therein. In coating millet seeds according to the invention to produce medicated, healthful and palatable bird seed containing between 0.30 and 0.50 m.g. of chlortetracycline per gram of seed, the seeds are hulled and scarified in a centrifugal impact huller 35, Figs. 5A and 6, comprising a rotating wheel or cage 39 having a flat base and an upper peripheral ring connected by peripheral rods. The seeds are fed, through a hopper 36 and an annular passage 49, on to the flat base, from which they are flung radially outwards, between the rods against the frusto-conical surrounding surface 54 of an inner wall 53, made of yieldable material such as rubber. The scarified seeds and detached hulls are drawn, by a fan 69, through a duct 57 into a sieving and cleaning device 58, in which large particles of detached hulls and broken seeds are removed through an inclined screen 63 and smaller particles thereof are removed, through a duct 71, by the winnowing exhaust from the fan 69. The cleaned seeds are discharged through an outlet shoot 66 and conveyed, by the buckets 78 of a chain elevator 74 and a helical conveyer 80, into a helical conveyer 85 containing an aqueous solution 88 of chlortetracycline (aureomycin) hydrochloride. The seeds soaked with the solution are discharged from the conveyer 85 into a draining device 95, Fig. 5B, comprising a vibrating screen 96, through which any excess solution is removed. The seeds are then carried, on an endless conveyer 112, through a drying oven 113, Fig. 12, in which heated air is circulated by blowers 134. As they enter the oven, the seeds are evenly distributed on the conveyer 112 by sweeping members 120 on two transverse continuous, travelling belts 114 and 115, whose lower flights are adjacent the carrying surface of the conveyer and move the members 120 away from its centre. The oven is divided into compartments 123, 127, 128 and 129 by partitions 130, 131 and 132. In compartment 123, rakes 124 and 125, having tines 126, break up any seed clusters. In compartments 128 and 129, transverse bars 135, tethered by chains 136 to the corresponding partitions 131 and 132, exert a tumbling and mixing action on the drying seeds. The dried seeds are discharged on to a cooling belt (not shown) which carries them to packaging apparatus (not shown).

Title: Elevator Control Supervisory System
IPC: B66B1/20
Filed: 1967-10-17
Abstract: 1,164,063. Lift control systems. ELEVATORS PTY. Ltd. 17 Oct., 1967 [18 Oct., 1966], No. 47179/67. Heading B8L. The floors served by a multi-car lift system are grouped into Sections S1 . . . S4 and a landing call is answered preferentially by a car parked within its section. During normal operation the cars park at their last destination; the first car to park in a Section is termed the " guardian car " and preferentially answers calls made in its Section. Further cars parking in the Section are " random ears ", and a call made in a section having no " guardian car " is answered by the nearest " random car" if there is one, and if not, by the nearest " guardian car ", although preferentially a landing call is answered by a car travelling past it in the appropriate direction if it is not overloaded. If two adjacent Sections are left with no " guardian car " and there are no outstanding calls the nearest " random car " is dispatched to one Section. The landing call buttons are grouped into up and down Sectors; if a call is not answered immediately it is stored in a Register according to its Sector and the calls pass through the Register from one end to the other so that the call appearing at the Register output is that which has been in longest and its Sector is made the " Priority Sector ". Allocation of floors to Sectors and Sections is made by terminal blocks which permit easy alteration. Operation is modified, for Up Peak and Down Peak times, detected automatically by the loading of the cars or the frequency of the loading. During Up Peak, two or more, or all, cars are allocated to the main floor; if only one is present, up calls are ignored, and if neither is present both up and down calls are ignored. During Down Peak, preferance is given to down demands over Up demands, which remain in the store until they are eventually answered. The system comprises relay circuits which are described in detail, and it includes a pulsing relay arrangement whereby "lift coming" lanterns are illuminated when the car is within six floors of the appropriate landing.

Abstract: 1,046,856. Jointing. LIPS N.V. Dec. 9, 1963 [Dec. 13, 1962], No. 47192/62. Heading B3V. A method of connecting two members 1, 2 together comprises sealing the ends of the outer member 2 about the inner member, filling the space between the members with uncured resin under pressure so as to expand the outer member 2, and maintaining the pressures during setting of the resin. The method may be used to connect a gear-wheel to a shaft, a flange to a pipe or shaft, or a sleeve to a ship's propeller shaft. Rigid plastics such as nylon may also be connected. The sleeve 2 is sealed by 0-rings 7, 8 bearing on glands 9, 10, which may be bolted to the sleeve or pressed towards each other by members urged together as by steel ropes. Trestles 3, 4 support the members with an exhaust hole 6 uppermost and a supply hole underneath which is connected to a container 11 for a resin, such as the epoxy resin known by the Registered Trade Mark " Araldite " and a hardener. A floating piston in the container may separate the resin from compressed air or nitrogen from a bottle 13. After air has escaped through the hole 6, this is plugged and the sleeve 2 expanded. The lower hole 5 may then be plugged or left connected to the resin supply during the setting process. The sleeve contracts against the resin, which has an adhesive action on the shaft and sleeve. It is stated that the sleeve may be loosened by heating to 270‹ C.

In order to control the quality of printing in a web-fed rotary multi-colour multi-unit printing machine any possible deformation of the web is monitored at locations before the web enters the first unit, between every unit and after the web leaves the last unit such monitoring is effected by using pairs of web guiding rollers 3, 8/4, 8/5, 8/6, 8/7, Fig. 1, the lower roller of each pair being allowed to swing about the axis of the upper roller should variations in the tension of the moving web occur. Such movement of the lower roller will alter the distance between a flat surface such as 14, Fig. 2, and an air jet issuing from a nozzle 15, which, in consequence, will cause an alteration in the reading of a manometer 13. Should the web break the machine will automatically stop as movement of any one lower roller through an arc equivalent to a drastic loss of tension will uncover electrical contacts, controlling the machine drive, which are placed in the associated manometer. Instead of pneumatic electrical or optical monitoring devices may be used.

Title: Method and apparatus for precision heat treatment of springs
IPC: C21D9/02
Filed: 1964-12-02
Abstract: In a method of and apparatus for heat treating a spring to give it a set such that it will have a specified relationship between deflecting load and a dimension of the spring which varies proportionately to load, the temperature of the spring is steadily raised while the latter is deflected under load, the heating being terminated as soon as the desired relationship between dimension and load is reached.  A particular form of apparatus described and illustrated (Fig.1) for the treatment of coil springs in tension has two holders 9, 10, the position of the latter being adjustable so that when plunger 13 is moved to its lower "loaded" position by pneumatic cylinder 15 operating through lever 19 the spring is extended to a specified length. The upper holder 9 is mounted on a balance lever 8, on the opposite end of which is a contact 22, which when the spring is initially loaded passes current through fixed contact 21, the current flow being along lever 8 by suitable means, through holder 9, spring 12 and holder 10.  Balance weight 27 is adjustable so that immediately the reaction force of spring 12 falls to the specified level appropriate to the preset length the current flow through 21-22 is interrupted and heating stops.  A modified form of apparatus for treatment of compression springs is also illustrated, as is a suitable circuit for semi-automatic operation of the apparatus.
