Title: Improvements in or relating to preparing materials comprising clay for building purposes
IPC: C04B14/12
Filed: 1961-01-12
Abstract: A material suitable for building purposes is prepared from material comprising clay by forming plastic clay into particles, providing each of the particles with a coating which prevents them adhering to each other and then bringing together the coated particles and a bonding material so that the bonding material surrounds the particles.  The coating may be formed by lime, cement or sand, by transient heating of the surfaces of the particles, or by chemical action e.g. acid.  The bonding material may comprise water with cement, trass, lime or plaster of Paris, and include such additional materials as sand, gravel, coral or lava.  The clay may be rendered porous by the incorporation of gas-evolving products prior to the formation of particles, According to an example, two parts by weight of naturally moist clay are first crumbled into particles which are then coated with one part of sharp edged sand, and the coated particles are mixed with 9%, based on the total, of cement to form a concrete that is adapted to be cast and tamped in moulds made of steel sheets or in separate moulds.  Lime may be incorporated with the clay during crumbling.

Title: Improvements in or relating to code conversion circuits
Inventor: ROBERTS ERIC
IPC: H04Q3/00
Filed: 1961-01-13
Abstract: 922,997. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Dec. 13, 1961 [Jan. 13, 1961], No. 1436/61. Class 40 (4). [Also in Group XXXVIII] In a subscriber's line concentration system, a serially received natural binary-coded signal operates relays IP, OP respectively in accordance with the " 1's " and " 0's " of the signal, and these relays control the operation of relays 0V-15V in such a way that at the end of the signal only that relay which corresponds to the binary signal is in the operated condition. Contacts IP1, OP1 provide operating signals for relays 0V-15V, and contacts IP2, OP2 provide temporary holding circuits for relays which are operated in the course of reception, this circuit being broken by the release of IP, OP at the end of the signal. The seriesconnected contacts 0V1-15V1 provide a permanent holding circuit for the last-operated relay. As an example, the binary signal 1010 (ten) causes the following operations. The first digit " 1 " operates 15V over 0V2, 1V3-3V3, 5V2 and 7V2 and 15V1 completes a holding circuit to HE. The second digit " 0 " operates 14V over 15V2 and a holding circuit for this relay is completed at 14V1, 15V holding over OP2. The third digit " 1 " operates 13V over 14V2, a holding circuit is completed for this relay over 13V1, 14V holding over 14V1, IP2. The final digit " 0 " operates 10V over 13V3 and a holding circuit is completed for this relay over 10V1. When OP releases, only 10V is left operated. The relays may be replaced by the select or holding magnets of a cross-bar switch.

Abstract: 1,086,802. Wrapping machines; endless conveyers. BATTLE CREEK PACKAGING MACHINES Inc. Jan. 12, 1965, No. 1436/65. Headings B8A and B8C. In a packaging machine, a sheet 30, Fig. 6, of a deformable material with flexible fingers 33 distributed over its surface is attached to the upper surface of a vertically reciprocable elevator platform 32, which lifts an article 29, to be packaged, from a conveyer 1A up under a wrapping sheet 14A to the level of horizontally reciprocable plates 34, 35. The flexible fingers permit these plates to push the wrapping sheet under the article without damage to the article or platform and also to remove the article from the platform. The elevator can either lift the article from the end of a conveyer as in Fig. 6 or from between the chains of a conveyer, Fig. 1 (not shown), in which case the platform (11) is guided by linkage (6, 7, 8, 9, 10, 57) to move in a closed path, to compensate for the continued movement of the conveyer. Alternatively, if the conveyer is stationary during this operation the platform may reciprocate along the same path. Similarly the motion of the platform may be downward rather than upward and the wrapping paper may be folded under the article by moving the platform horizontally relative to a single bottom fold plate. The sheet 30 or (22), Fig. 2 (not shown), may be made of rubber while the fingers can be made of wire or natural bristles. In a modified form the sheet (22) has a number of upstanding flexible ribs (23A), Fig. 5 (not shown).

Title: Process for recording numerical  and alpha-numerical infor mation on a magnetic support
IPC: G06K1/12
Filed: 1974-01-11
Abstract: 1460767 Recording data CBIZZARRI 11 Jan 1974 [15 Jan 1973 22 May 1973] 01460/74 Heading G4C Alphabetic and numeric data is recorded on a magnetic medium, e.g. a tape or disc, only significant characters being recorded, together with a mask consisting of one bit for each character, including non-significant characters, each mask bit having one value when the corresponding character is significant and the other value when the corresponding character is non-significant and therefore omitted from the recording. The procedure may be applied to recording personal records and several variations are described. In the first, two distinct zones containing numeric data only (e.g. registration numbers) and mixed data (e.g. name, address &c.) respectively are recorded. Zeros in the numeric zone and spaces in the mixed zone are regarded as non-significant and the mask bits are established accordingly, a further field being provided to indicate the division between the zones. The arrangement may be applied to conventionally recorded data, the conventional record being read and re-recorded with non-significant characters omitted. In a modification the record is not divided into zones, the mask field being established irrespective of the nature of each non- significant character. A second mask is then established with one bit for each non-significant indicating bit in the first mask, each second mask bit indicating whether the corresponding non-significant bit is a zero or a space. A further field may be established indicating the total number of suppressed characters, i.e. the number of bits in the second mask. In a further modification n (more than two) characters may be suppressed, (n-1) second mask fields being provided to indicate, to which suppressed character the non-significant indicating bits in the first mask relate.

Abstract: 488,800. Testing physical qualities of materials. EUGENE, F. Jan. 20, 1937, No. 1680. Convention date, Jan. 30, 1936. [Class 106 (ii)] A machine for making bending, shearing, compression, tensile and hardness tests comprises means for securing a test piece, a load applying device, calibrated resilient bars capable of co-operating with said securing means the movement of which against the resistance of the bars is transmitted to a movable mirror, a second movable mirror to which the distortion of the test piece is transmitted, a reading screen and means for projecting a light ray on to the screen after reflection at least from the first mirror, and means for clearing the path of the ray so as to be reflected also in a second mirror. The load applying means is constituted by a vertical shaft adapted to slide without turning in the head of a frame 1. The shaft is screwed to engage a nut mounted in ball bearings and turned by pulley and worm gear from a motor carried by the frame 1, and is prevented from turning by a key which may be withdrawn to allow of rapid movement of the shaft. A table 23 the stem of which slides in ball bearings engages by a stud 24 one of three resilient bars 30, which are arranged in a unit 31 which may be slid by levers 34, 35 to bring any bar underneath the stud 24, the bars having blocks 37 to give them the same height at the centre. The bar 30 engages a stud 43 on the short arm 44 of a lever pivoted at 45, the long arm 41 of which has attached to it a metal tape 42 the other end of which is attached to a pulley 52 on a spindle 49 carrying a mirror 40. The table carries a bracket 66 and yoke 67 for supporting the specimen a as shown. A lug 70 on the yoke is adapted to engage one arm 71 of a bell-crank lever, the other arm of which engages a pivoted mirror 73, which is tilted an amount proportional to the distortion of the specimen. Light from a source 81. passes through a hole 4 to mirror 73 and is reflected to mirror 40 and from there to another mirror and then to the reading screen. For shearing, compression and hardness tests, the light is reflected via mirrors 85, 89, 90 to 40 and then follow the same path as before. These paths are of equal length to avoid having to focus the reticules every time a change is made in the nature of the test.
