Title: Handling and baling system for trash and other materials
Inventor: BOYD JOHN ALLISON
IPC: B30B9/30
Filed: 1968-12-16
Abstract: 1,248,597. Baling machines. TRANSWORLD COMPACTORS (BVI) Ltd. 16 Dec., 1968, No. 59762/68. Heading B5F. In apparatus for baling rubbish in a multistorey building, the rubbish is fed through a shoot 12 and directed by directing means 10 into baling means 14 including a vertically reciprocable plunger 106 (Fig. 4b) the directing means 10 containing first and second control means 16, 18 the first of which is controllably coupled with the plunger 106. The control means 16, 18 may comprise photo-cells. When the rubbish is sufficient to obscure the photo-cell 16 for a preset time the plunger 106 is operated. When sufficient rubbish is present to obscure the photo-cell 18 also, a door 50 is released by a solenoid 58, and closed by weights 70. The door 50 closes the shoot 12. While material is being compressed the inlet to the baling means is closed by a door 112 carried by the plunger 106. The baling means includes three hinged doors 86, 90 and 94. A blower 26 coupled to a deodorizing collar 20 creates a downdraught in the shoot 12.

Patent GB-1215349-A (GB)
Title: Measuring device
IPC: G01D5/36
Filed: 1968-12-30
Abstract: 1,215,349. Optical apparatus. ERNST LEITZ G.m.b.H. Dec.30, 1968 [Jan.19, 1968], No. 61610/68. Heading G2J. [Also in Divisions G1, G4] A measuring device comprises jaws 3, 4 for determining the measurement position of an object 5 being measured, a graduated scale 17 and a reading system including a source of illumination 10, an image forming system 13, 14 and a plane mirror 15, the image forming system and the plane mirror forming an image of the graduations of the measuring scale on the measuring scale. The measuring device as shown comprises a sliding jaw calliper, the mirror 15 and a Wollaston prism 16 being mounted on the slidable jaw 4 whilst the rest of the optical system including prisms 22-26 and a double mirror or prism 13 are mounted on the jaw 3. The beam from the source 10 is reflected by the prism 22 and the interface between the prisms 23, 24 before passing through the scale 17 and undergoing two reflectors in the prism 13. A lens 14 collimates the beam which is then reflected from the mirror 15 and the prism 13 to form an image of the scale at the point 36. If, however, the jaw 4 and consequently the mirror 15 are tilted by an angle αthe image is formed at the point 42. The distance between the points is f tan 2a where f is the focal length of the lens 14 and is made equal to the distance between the scale 17 and a line journey points 30, 31. The Wollaston prism splits the beam into two orthogonally polarized beams separated by a small angle thus producing at the point 36 two orthogonally polarized images displaced from one another by one quarter of one period of the graduations of the measuring scale. The beams on passing through the scale generate signals differing in phase by 90 degrees, the signals being separated by the polarizing beam splitting prisms 25, 26 and fed to respective photo-electric receivers 20, 21. The photoelectric receivers are connected to a counter and the system enables counting in a forward or backward direction to enable the length measurement to be compensated for tilting of the jaw in either direction. The tilting of the jaw produces an error or difference between the length of the path 30-31 and the length indicated by the scale of a = ftan α but the fact that the scale and its image move in opposite directions results in the photo-electric receivers measuring an error of 2a. However since tan 2α equals 2tanα the distance between the points 36, 42 equals 2a. In a modification the optical system is applied to a microscope.

Title: Method and apparatus for forming plastic articles from sheet material
IPC: B29C51/26
Filed: 1969-12-29
Abstract: 1,255,050. Sheet forming. MONSANTO CO. 29 Dec., 1969 [30 Dec., 1968], No. 63095/69. Heading B5A. In a sheet forming process in which a heat softened sheet is plunger assist vacuum formed into a mould having a plurality of cavities forming longitudinal and transverse rows, the sheet is clamped during the forming around the periphery of the mould and is clamped within that periphery only between transverse rows of cavities. In the illustrated embodiment, a sheet S of a rubber modified A.B.S. terpolymer is heat softened by an oven and drawn by plungers 32 into the vacuum cavities 18 of a cooled mould 14. The sheet is clamped in the above fashion against the mould by a reciprocable clamp comprising an external frame 48, 46 and transverse ribs 46 each topped with resilient strips 50. The strips engage a stripper plate 28 carried by the mould. The sheet is supported against sagging at the moulding station by longitudinal wires 54 accommodated in grooves in the ribs 46. After forming, the sheet is forwarded by a hydraulic clamping device reciprocable along a bar located below the sheet (see Fig. 4, not shown) to a separating means where the articles are sheared from the rest of the sheet. Air may be blown through the plug to assist in the forming of the sheet. In constructions not using a stripper plate, the sheet is clamped directly against the leading surface proper of the mould.

The panoramic telescope shown in Fig. 2a comprises an apertured mirror 1 reflecting light to the concave mirror 13 whence it passes an erecting prism 14, Fig. 2b to reach the eyepiece 16. The mirror 12 is rotatable about a horizontal axis on a member 20 rotatable about a vertical axis ab and carrying a gear meshing with a pinion 19 on a shaft 19a connected to the prism 14 so that the latter rotates about the axis ab at half the speed of the mirror 12. The correcting lens, not shown, may be concentric with its common centre of curvature at the point of intersection of the rotation axes of the mirror 12, or may rotate about a horizontal axis with the mirror 12 but at twice the speed. Two telescopes may be hinged together. The mirror arrangement may also be used as a photographic objective. Specifications 637,645, 638,975 and 677,982 are referred to.

Abstract: 702,993. Knitting-machines. HEMPHILL CO. Sept. 26, 1950 [Nov. 22, 1949], No. 23577/50. Class 74 (2) A knitting machine pattern drive acts through linkwork 24, 21 and pin and slot connection 20, 19, to depress or elevate the nose of a lever 17 and so either force down a yarn guide-carrying slide 5, until a stud 7 thereon meets an adjustable stop 8, or allow it to rise, under the action of a spring 10, until the slide meets an upper adjustable stop 16, the yarn guide 6 being thus moved between a low yarn-introducing position and the normal feeding position: continued upward movement of the nose of lever 17 will tilt a bell-crank lever 15, 14, and so move the stop 16, carried on the arm 14, out of the path of slide 5, allowing the yarn guide 6 to rise to an uppermost inactive position, limited by abutment of pin 7 against lever 17. Reverse movement of the lever 17 will lower the yarn guide 6 and allow a spring 25 to restore the stop 16 to its active position. A stop 26 prevents arm 15 being swung so far that spring 25 could not return it.
