Title: Apparatus for Feeding Livestock
Inventor: JOHNSON THOMAS EDWARD
IPC: A01K5/02
Filed: 1967-10-23
Abstract: 1,173,973. Automatic feeding arrangement. T. E. JOHNSON and 0. S. SIMON. 23 Oct., 1968 [23 Oct., 1967], No. 48022/67. Heading AIM. [Also in Division B8] Livestock feeding apparatus comprises a belt conveyer 6 overlying a series of feeding stations 2, means 38, 40 at the upstream end of the conveyer to supply feed thereto at a controlled rate, and a driven plough assembly 52 mounted for travel along at least part of the conveyer run. The plough assembly includes a blade 58 extending obliquely across the width of the conveyer belt whereby movement of the blade lengthwise relative to the conveyer run will discharge feed from the swept area into the underlying feeding stations. The plough assembly comprises a trolley 54 attached by a cord to a motor 70 so that in one direction the plough is drawn by the motor against the direction of movement of the belt - in the other direction frictional engagement with the belt carries the plough downstream at a speed governed by the motor 70. Alternatively in one direction the plough may be lifted from the belt. Limit switches effect reversal of the motor 70. Other limit switches may be fitted to vary the feed supplied to different stations etc. Guides, which may be adjustable e.g. Fig. 4 (not shown) deflect the feed into different parts of the feeding stations or stations arranged at both sides of the plough. The plough is backed up by a brush 60.

Abstract: 1,067,849. Writing instruments. SCRIPTO PENS Ltd. Nov. 26, 1964 [Dec. 9, 1963], No. 48433/63. Heading B6P. An 0-ring 7 of rubber, an oil-resistant synthetic rubber or a rubber substitute such as polychloroprene, butadiene acrylic nitrile copolymer or a polyurethane, is retained in a groove 5 in the barrel of a fountain pen. A cap 3 is frictionally retained by the 0-ring when in place, as shown. Ducts 6 at diametrally opposite positions in the groove 5, provide vents to prevent the pen from leaking due to changes of atmospheric conditions. The 0-ring may be replaced by a resilient rubber ring not necessarily of circular cross-section, which could be seated in a relatively shallow groove, and cemented in place if necessary.

Filed: 1970-10-13
Abstract: 1316299 Delivering sheets ADDRESSOGRAPH-MULTIGRAPH CORP 13 Oct 1970 [13 Nov 1969] 48637/70 Heading B8R Apparatus for separating two superimposed sheets, e.g. an original and a copy sheet issuing from a photo-copying machine, comprises devices for advancing the sheets along a path with one of the sheets being moved faster than the other, and means for deflecting the fastermoving sheet from the path. As shown, the original and copy sheets 14, 16 respectively are directed by a guide 78 from the copying machine to the bite of two rollers 58, 60, the roller 58 being driven at a faster speed than the roller 60. The rollers 58, 60 may be rubber-covered or may have staggered rubber rings thereon. As the copy sheet 16 is moved forward at a greater speed than the original 14, its leading edge is deflected away from the sheet 14 by an upward air blast, a fixed roughened curved guide or a roughened rotating roller 84. In the latter arrangement, the roller 84 causes the sheet 16 to bend as shown to aid in deflecting the original below the roller 84. Guides 96, 102 direct the copy sheet to rollers 54, 56 which feed it back into the machine for further processing.

The resistance of the circuit as seen by the fixed current IP remains the same as switches D 1 and D2 are moved. This current passing through selected portions of the first resistors generates a voltage to oppose the unknown potential. The position of switch D 1 gives the highest decimal digit and switch D2 gives the next highest, the circuit being two similar potentiometer circuits connected in series. The sharing of the current between the spaced contacts D 1 1 , D1 2  is controlled by a circuit comprising a tapped resistor 58 and selector switch D3, each step of which a voltage drop between the spaced contacts of 0À01 units and a similar switch D5 which has a value of 0À0001 for each step. Similar right-hand switches have values of 0À001 and 0À00001, the six switches thereby giving six decimal places. A galvanometer is connected in series with the unknown potential and the control dials are turned to give a zero reading, the unknown potential then being balanced by the known current passing through selected portions of the first resistors.

Abstract: 1,077,280. Photographic cameras. EASTMAN KODAK CO. Dec.23, 1963 [Jan. 5, 1963], No. 50612/63. Heading G2A. A photographic camera comprises an objective lens, a shutter, a release member, a mechanism controlled by said member to initiate operation of the shutter a predetermined time after actuation of said member and to move a photo-responsive device of an exposure meter out of a ray path of the objective lens at a predetermined time prior to the operation of the shutter. In the embodiment shown in Fig. 1 the device 10 is shown in position in front of the objective. When camera release 2 is moved downwards manually, lever 3 causes the shutter mechanism to operate in a known manner and rotate pinion 4 to move rack 5 to the left.

Abstract: 1,160,550. Rotary filter. FISONS FERTILIZERS Ltd. 11 Jan., 1967 [1 Dec, 1965], No. 50910/65. Heading B1D. A downward flow rotary filter comprises a series of circumferentially spaced cells 26, 27 rotating about a common vertical axis, the filtering floors 24, 25 of which are raised to level with the top of their peripheral walls at a discharge station where a plough or rotary scroll 23 moves the filter cake. The raising may be performed by electric, pneumatic or hydraulic means, or by extensions 15 from the floors running in tracks 22 which rise at the discharge stations. A common distribution valve (3), located at the axis, applies suction to the cells round most of their path from the slurry supply station, but delivers reverse flow air in two steps and applies suction again, to dry the filter cloth covering the perforate cell bases, where a cell passes the discharge station. In addition, jets of water are directed radially across the cell to aid scroll 23 in removing the cake and to wash the cloth, between the two deliveries of air. To prevent the water from reaching the adjacent slurry supply station a resilient barrier engages the moving filter cell floors, or a suitably directed compressed air jet may hold the water back. The cells are carried on rollers in inner and outer circumferential tracks and rotated by a pinion engaging a peripheral rack. A cake washing station may be provided.
