Abstract: 429,956. Poultry houses; preventing access of vermin. ALLAN, A. B., Auchinleck Farm, Newton Stewart, Wigtonshire, and HOWIE, J. M., Oakholme, Dunlop, Ayrshire. Feb. 10, 1934, Nos. 4500, 18976, and 25647. [Classes 5 (i) and 5 (ii)] [See also Group XXV] A door structure for a house for poultry, game, and other birds, comprises an entrance and exit opening associated with a movable platform extending on either side thereof and providing a path therethrough, such opening being normally closed but being openable by the application of the weight of an incoming or outgoing fowl to the outer or inner part of said platform. A door structure, 11, Fig. 1, attached to the wall 10 of a poultry house comprises a horizontal platform 16 and a shutter 17, weighted at 18 and provided with lugs 19a on lateral guide members 19, such lugs engaging vertical guides 20, the platform and shutter being interconnected by pivoted links in such manner that depression of the platform causes upward movement of the shutter. An auxiliary shutter 21, secured to the bottom of the platform also comprises lateral guide members having lugs 22a engaging the guides 20. When it is desired to prevent the exit of fowls, a hinged masking member 30 is turned downwardly to prevent fowls alighting on the inner end of the platform. In a modification, Fig. 3, the platform comprises inner and outer part platforms 43, 45 connected together at 52, pivoted at 44, 46 to base members 42 and connected to a hinged shutter 47 by a link 50; an auxiliary shutter 53 is also connected to the part platform 43 ; in this form, fowls may be prevented from leaving the house by turning the part platform 45 into the position shown in dotted lines. Means may be provided for positively locking the shutter or shutters in the closed position. In a further modification, a single shutter is attached to the underside of a platform and slides in lateral guides, the platform and shutter being overbalanced by a weighted lever. In another modification, platform and shutter are interconnected by a cord passing over a pulley, instead of by a linkage. The structure may be located on the inside of a house, as shown, or on the outside : in the latter case, a protective covering may be provided.

Abstract: 1,024,945. Wrapping-machines. ABITIBI POWER & PAPER CO. Ltd. Feb. 3, 1964 [Sept. 27, 1963], No. 4521/64. Heading B8C. A roll of paper 215, having a wrapper wound round it but protruding at either end 217, Fig. 2 (not shown), is supplied to automatically adjusted crimper blocks 225 which are rotatable to crimp the ends 217. As the roll 215 is fed over the first of a pair of rollers 205, 206 the operator presses a switch operating a pneumatic circuit to raise a roller 212 against which the roll comes to rest. Each of the blocks 225 is moved pneumatically towards the ends of the roll 215 on actuation of a second switch, the blocks being attached to flanges 224 of sleeves 221, Fig. 1 (not shown), slidably mounted on each end of the roller 206. Sensing members 247, Fig. 2 (not shown), each carrying a switch, touch the roll ends thereby arresting the blocks 225 independently. A third control switch is used to lower the roller 212, allowing the roll 215 to come to rest between the rollers 205, 206 which are rotated with the blocks 225 on the operation of a fourth switch. After crimping, the blocks are withdrawn, the drive to the rollers 205, 206, broken, and the roil ejected. Reference has been directed by the Comptroller to Specification 961,790.

Title: Improvements in and relating to gear control devices for use in automobiles and the like
IPC: F16H59/02
Filed: 1956-02-14
Abstract: 804,701. Variable-speed gearing; clutch actuation. FRANCAISE DE FERODO S.A. Feb. 14, 1956 [Feb. 14, 1955; Dec. 30, 1955], No. 4651/56. Addition to 751,785. Class 80 (2). [Also in Group XXXVII] The two-part gear lever of the parent Specification is modified by providing the associated switch with a contact on each of the two parts and with a centring device including two relatively movable members urged towards a balanced position by resilient means. As shown, a contact 132 connected to a conductor 11 is carried in a gear control member 10 fixed to a socket 12 and the co-operating contact member 137 is resiliently connected to actuating rod 19 by a coil spring 144. The rod 19 is centralized in the sleeve 12 by a spring 27 urging a spherical collar 24 on the rod against an abutment 26. In this position the contacts 132, 137 are spaced apart with the contact 137 engaging the rod 19 at annular abutment faces 140, 141, a convex part 139 of the contact 137 entering a recessed part 142 in the rod 19. Initial movement of the rod 19 before the latter engages an abutment surface 146 on the socket 12 closes the contacts 132, 137 and produces relative movement between the contact 137 and rod 19 with distortion of the springs 27, 144. When a gear change has been made and the rod 19 released the springs 27, 144 restore the contacts to the open position shown in Fig. 2. In a modification the spring 144, instead of being screwed to the parts 19, 137, has its end coils engaging an annular groove in these parts. In another modification the coil spring 144 is omitted and the contact members are centralized by a surrounding rubber bushing. In a further modification the contact 132 is a spherical headed pin which is mounted in the member 10 by a spring-urged spherical collar member.

Title: Improvements in devices for packing slivers into cans
IPC: B65H54/78
Filed: 1931-02-14
Abstract: 370,110. Packing slivers into moving cans. MACKIE & SONS, Ltd., J. and MACKIE, J. P., Albert Foundry, Belfast. Feb. 14, 1931, No. 4725. [Class 120 (iii).] In packing sliver as it is delivered into a moving can 2, by packing-members 5, 5a which are lowered into and raised out of the can during the filling operation, the motion of the packing-members is derived from the motion of the can or of a member moving therewith. The can 2 is mounted on a reciprocating platform 3 which is provided with a plate 13 notched centrally so as to present three horizontal surfaces 14, 15, 16 and two inclined surfaces 17, 18. The packing-members 5, 5a are carried by independent parallelmotion linkages 7, 8, 9 ; 7a, 8a, 9a pivoted on the machine frame, the links 9, 9a being provided with rollers running on the working surfaces of the plate 13. The horizontal surfaces 14, 16 are respectively extended by horizontal members 22, 22a which are offset from supporting arms 21, 21a pivoted at 20. As shown, the platform 3 and can 2 are at the right-hand end of their travel and the packing-member 5 is operative and inside the can 2. When the platform 3 and plate 13 move to the left the incline 17 forces the roller 12 to rise, to lift the member 21, 22 and engage the surface 14, while the roller 12a passes from the surface 16 to the surface 22a and then drops on to the surface 15, the member 5a thus delivering a packing blow to the sliver in the can 2. On the return stroke the roller 12a is lifted by the incline 18 and the member 5 again becomes operative. To avoid dragging the top layer of sliver while in contact therewith the members 5, 5a are curved and freely pivoted on the rods 7, 7a. When modified for a rotating or oscillating can one packing member is provided and the plate 13 arranged round the platform which carries the cans. Specifications 290,791, 317,029, 323,596, [all in Class 120 (iii), Yarns &c.], and 370,082 are referred to. Specifications 311,556, 333,396, 334,413, [all in Class 120 (iii), Yarns &c.], and 370,081 also are referred to in the Provisional Specification.

Title: Deflector system for the stacking in edge registration of pieces of strip material
IPC: B65H29/58
Filed: 1966-02-03
Abstract: 1,066,558. Delivering sheets. H. GEORG. Feb. 3, 1966 [Feb. 5, 1965], No. 4838/66. Heading B6H. A deflector system for stacking, in edge registration, pieces 3 of strip material which are coming in direction 8 from a guide roll table following pivoted shears, and whose front cut edges extend alternately at different inclinations, comprises a skew wedge 4 having wedge surfaces 5, 6 meeting in an edge 7. The edge 7 inclines both to the direction 8 and to the plane of the pieces of material 3 and intersects the longitudinal centre line of the pieces 3. Consequently the acute-angled comer 9 of the wedge 4 comes above the plane of the pieces 3 and the obtuse-angled corner 10 of the wedge comes below that line. When a piece 3 with a point on the right (as regards the direction of travel) contacts the surface 6, it guides the piece 3 to an upper path comprising guides (18) and feed rollers 14. A piece 3 with a leading point on the left is guided by the wedge surface 5 in a downward direction where it is fed by rollers (15) to a lower stack. Both rollers 14 (15) have co-operation rollers which are coupled together by a common spring (16) and thereby urged to their respective feed rollers. The guides 21, 21 are provided adjacent the rollers 14 (15) and may be substituted by extensions of the wedge 4 (Fig. 3, not shown).

Abstract: 1,168,152. Protective arrangements. RUMANIA, MINISTRY OF MACHINE BUILDING INDUSTRY. 2 Feb., 1967 [3 Feb., 1966], No. 5084/67. Heading H2K. [Also in Division H1] A polyphase protective relay arrangement comprises a current coil 17 ... 19 for each phase, a movable magnetic core 6 ... 8 for each coil, a vertical passage 2 ... 4 for each core, the passages being in communication with one another and filled with liquid, and an armature 11 which is attracted to open contacts 12 when any core reaches the top of its passage. The passages communicate with one another at the top as well as at the bottom. As shown, the cores have slits to permit free movement of the liquid when the cores are in their lowest position. Under balanced overload conditions, all the cores move and their movement is delayed by the relatively slow passage of liquid past the cores 6 ... 8, so that opening of the contacts is effected with a time delay inversely related to the magnitude of the current. Should a phase be interrupted, the core associated with that phase will not move and the other cores will move without delay.

Title: Moulding polymeric material
Inventor: EAGLETON SIDNEY DOUGLAS
IPC: B29C67/24
Filed: 1962-02-12
Abstract: A sheet of polymer is softened by heat and shaped to the required extent, the polymer being the product of an ethylenic monomer with a resin which has the structure of a copolymer of an olefinic hydrocarbon with a comonomer, the copolymer containing substituent acyloxy groups derived from acrylic or an a -substituted acrylic acid.  The monomer may be styrene, the olefinic hydrocarbon may be ethylene and the comonomer may be vinyl acrylate or methacrylate. The sheet may contain a reinforcing filler, e.g. 15-35% glass fibre, and may be shaped by vacuum or pressure forming.  In an example styrene was polymerized with a terpolymer of ethylene, vinylacetate and vinyl methacrylate using caprylyl and dicumyl peroxides to form a syrup which was then moulded and heat treated to form a sheet.

Abstract: 955,796. Volume control. PYE Ltd. Feb. 6 1961 [Feb. 15, 1960], No. 5304/60. Heading H4R. In a volume control arrangement diodes 4 are connected one in series with each conductor of a 2-wire line and the conductance of the diodes is controlled by a low impedance bias source including a transistor 6 having its emitter con nected through a load to one pole (-) of a stabilized D.C. supply and its connector connected through a further load to the other pole of the D.C. supply, the base of the transistor 6 being fed with an adjustable D.C. voltage and the bias to the diodes 4 being taken from the collector of the transistor 6, whereby variation of the D.C. voltage applied to the base of the transistor 6 varies the bias applied to the diodes 4 and hence their impedance to an applied signal. In an automatic volume control arrangement (Fig. 3) the output of an amplifier 13 connected to secondary of transformer 2 is full wave rectified at 12 and the resulting output is applied to the base of transistor 6. The compression or expansion range depends upon the gain of amplifier 13, and the characteristic of the circuit may be varied by changing the value of capacitor 14 to give a different time constant. In a manual arrangement (Fig. 2, not shown) the base of the transistor 6 is connected to the slider of a potentiometer connected across the D.C. supply.
