Title: Systems for accurately positioning an object in a plane by means of translatory movements
IPC: G01B9/02
Filed: 1970-11-24
Abstract: 1339432 Optical position finding THOMSONCSF 24 Nov 1970 [25 Nov 1969] 55920/70 Heading H4D To accurately position an object on a support 5, Fig. 1, subject to translatory X and Y movements, interferometers I 1 , I 2 , I 3 , and I 4 , cooperating with mirrors M x  and M y  on respective orthogonal sides of the support give indications of any lateral deviation E x  and E y  from the Y and X scans respectively and supplies such deviation signal to respective X and Y correcting units P x  and P y , each unit comprising a fixed platform 2, Fig. 2, and a moving platform 1, the two platforms being mechanically connected by distortable pillars 4 and a pillar 14 extending from the fixed platform up through the moving platform for engagement of a flexible cylinder 13, between a wedge cut in the pillar 14 and a wedge cut in the side of the hole in the moving platform 8. The moving platform being also coupled to the fixed platform for the correction of the deviations by two piezo-electric stacks 5, 7 operating between respective pillars 8, 9 on the fixed platform and the sides of respective holes 15, 16 in the moving platform. During initial setting up, the strains in the piezo-electric stacks are equalized by screw thread/nut/ball bearing, assembly 12, 11, 10. Equal correction voltages Ex1, Ex2 applied to the piezo-electric stacks produce a lateral movement Ex of the platform 1, whilst unequal voltages produce a rotational movement about cylinder 13. A simple laser La, Fig. 3, provides the beam for both interferometers via semi- and full-reflecting mirrors L 1 , L 2 , L 3 , M 1 , M 2 , the beams reflected from the mirrors M X , M Y  being detected together with respective reference beams from preliminarily adjusted mirror system S 1 , F 1 /S 1 , F 2 / S 3 , F 3 /S 4 , F 4  by detectors R 1 , R 2 , R 3 , R 4 . The fringes, detected from the beating together of the pair of beams are counted by counters Cr and indicated at Xa and Ya. The error voltages from detector pairs R 1 , R 2  or R 3 , R 4 , are added to give the lateral error voltage and subtracted to give the rotational error voltage. Reference has been directed by the Comptroller to Specification 1,196,281.

A number of L-shaped concrete panels 22 are cast in a battery of spaced L-shaped mould members 12 arranged one within the other and so that the plane C-C containing the corners of the members is at 45 degrees to the planes A-A and B-B containing the edges of their adjacent arms. By placing comer stops at the junctions of the two arms of each mould space flat panels may be produced. The assembly includes two such batteries, one a mirror image of the other, spaced apart on a base frame above which travels a concrete supply carriage 158 on rails whereby it can be brought over either of the batteries. The carriage includes a platform running on rails transverse the carriage movement and including a delivery shoot 174 for the concrete brought to position above the mould spaces. The concrete in the mould is compacted by vibrators and heated by steam admitted to the interior of each mould member which may consist of steel plates separated by girders. To prevent bending during casting, stiffening trusses 69, frames 70 and hydraulic rams 72, 77 base frame are provided. Clamping of the members is assisted by tie bolts 76 passing through spacer tubes 75, and latches connecting together pairs of adjacent members. The bottom of each mould space is closed by base-boards and the ends of the spaces by stops, each stop comprising a beam faced with a timber former 32. The position of each stop is adjustable by spacer tubes 38 of varying lengths. The mould members may be lifted by rams located above the shoot with chains extending therefrom through the shoot outlet to connect with eye-bolts on the members.

Title: Improvements in or relating to the production of laminar articles
Inventor: GARNER PAUL JOHNSON
IPC: B32B27/00
Filed: 1968-12-31
Abstract: 1,255,970. Injection moulding. IMPERIAL CHEMICAL INDUSTRIES Ltd. 17 Dec., 1969 [31 Dec., 1968], No. 61963/68. Heading B5A. In a process for making a laminate having a core and surface skin of dissimilar synthetic resin compositions, wherein a charge of the skin composition is injected into a mould cavity and subsequently a charge of the core composition is injected into the interior of the charge of the skin composition before the latter has set, the mould cavity is filled with the skin composition and then enlarged to allow the core composition to be injected. This enlarging of the mould may be effected by reducing the mould clamping force so that the injection pressure forces the mould halves apart. Alternatively the cavity may be fully enlarged before any of the core composition is injected. If the core composition is a foamable material the cavity is then further enlarged to allow foaming to take place. Three charges of material may be injected the third being of the same material as the first. One or more walls of the mould may be lined with a removable insert e.g. a sheet of wood, hardboard, metal or plastics or a flexible material to be incorporated in the moulded article. Articles specified are furniture, building panels and panels for cars and trains, interior trim for vehicles and seedboxes. Examples are given of suitable thermoplastic and thermosetting plastics and foaming agents. Reference has been directed by the Comptroller to Specification 1,156,217.
