Title: Improvements in and relating to the manufacture of bricks
Inventor: SWALLOW HENRY TYRRELL STANLEY
IPC: C04B28/22
Filed: 1960-11-03
Abstract: In the manufacture of bricks small pieces of clay are lightly calcinated in air, in order to oxidise and remove carbonaceous matter, to oxidise iron compounds and to dehydrate the material without destroying the alkaline earth carbonates, allowed to cool, ground and mixed with 10 to 30% by weight of calcium hydroxide before being made plastic by the addition of water and poured into moulds where the bricks are allowed to harden.  The clay or brick earth used as raw material may be of the kind normally used for making red bricks and the calcining process may be performed in a kiln or furnace, e.g. a rotary kiln, at 550 to 700 DEG C.  Before the addition of water the clay and Ca(ON)2 may be mulled such that 50% of the mixture passes a 200 B.S. sieve.  The hardening may be natural although it is preferable to expedite the process by steam treatment, e.g. in an autoclave.  In the example Lancashire Boulder Clay is heated in a kiln in air at 650 DEG C. for 3 hours, cooled, ground and added to Ca(ON)2 before remilling, adding water and allowing the moulded brick to harden under a load of 1/2 ton.  After two days the bricks are placed in an autoclave and subjected to steam at 100 lbs./in2 for six hours.

Abstract: 1,105,582. Electric digital computers. WESTERN ELECTRIC CO. Inc. 15 Sept., 1965 [5 Oct., 1964], No. 39327/65. Heading G4A. Apparatus for coding a plurality of signal sequences having error control formats respectively corresponding thereto, comprises means for storing control words respectively representative of the error control formats, a configurable coder, means responsive to a particular signal sequence for reading out of the means for storing the particular control word corresponding thereto, and means responsive to the readout of the particular word for selectively configuring the coder and controlling the overall sequence of operations thereof for coding the particular signal sequence. Data on a plurality of input lines (Fig. 1, not shown) is detected by a scanner which signals the control unit when data is detected. The signals on a particular line are abstracted and applied via a character register to a configurable decoder. The decoder is controlled by error format words each of which is associated with a different input line, which are stored in a memory 116 and read-out under the control of the control unit to code or decode the data on the appropriate line. As shown in Fig. 2, the decoder acts on 3 bit words to produce two 3 bit error signals or coding signals. The coder comprises a series of delay units 201, 202, ..., 206 separated by exclusive OR gates 218, 208, 209, 211, 213, 214. The data held in character register 110 may be transferred in parallel via AND gates 221-226 to the exclusive OR gates the same 3 bit word being applied to gates 221-223 and 224-226. The appropriate error format word is transferred from memory and in this case enables AND gate 270 and AND gates 272, 274, 276. Thus the first three delays and OR gates act as a circulating shift register, whereas the second three delays and OR gates circulate each particular bit around its own delay unit. After a time corresponding to 1 bit period the next 3 bit word is applied in parallel to the coder and appropriate bit positions are modulo-2 added by the Exclusive OR gates. This procedure is continued until all words are added. If the unit serves as a coder the two words held in the coder are the two check words. If the unit acts as a decoder the two words are compared with the check words received on the input line and any discrepancy produces an error signal. The unit may examine input lines on a time sharing. basis the coding being carried out while data is being received on the line and the result being stored when another line acts as input, the coder being set back to the stage it had reached when the first line is again sampled.

Abstract: 1,165,076. Typewriters; &c. SPERRY RAND CORP. 31 Aug., 1967 [12 Sept., 1966], No. 39948/67. Heading B6F. [Also in Divisions G4 and H1] A control element such as the key of a typewriter, calculator, &c., is biased to its normal position and is held in a control i.e. depressed position by latch means, and the biasing means includes means for operatively coupling the element and the latch means so that the latch means is moved to latching position when the element is moved to the control position. As described, a key 14 Fig. 1, in its latched position closes a switch 11 which may operate so that the up position of the key may represent one binary character and the down position may represent the other binary character. The key stem 15 is mounted on a frame member 16, Fig. 3, by means of a reduced part 20 engaging a slot 17 in a flange 18 on the member 16, and also by a slot 24 in the stem engaging a rod 25 fixed to the member 16 so that the stem has a limited up-and-down movement. Pivoted at 28 on the key stem 15 is a trip arm 27 the pivotal movement of which is limited by the engagement of a lug 30 thereon with the edges of a slot 31 in the key stem. A bail member 32 is pivoted about the rod 25, the pivotal movement being limited by a lug 33 on the bail engaging the edges of a slot 34 in the frame 16. Another lug 40 on the bail 32 can be engaged with the lower edge of a recess 41 in the key stem to hold the key depressed. Two further lugs 35, 36 are provided on the bail 32, which lugs co-operate with the lower edge 37 of the trip arm 27 as described later. The ends 43, 44 of a coil spring 42 engage pins 45, 46 on the arm 27 and bail 32 respectively. In the raised or inoperative position of the key, the spring 42 holds the parts 27, 32 in the positions shown in Fig. 1 and biases the key upwardly with shoulders 22, 23 on the stem abutting against the flange 18. An additional spring 51 with an extending part 52 engaging a slot in the key stem 15 may be provided to reinforce the upward bias. When the key is depressed, the lower edge 37 of the trip arm 27 eventually engages the lug 36 on the bail 32 thus pivoting the bail 32 in a clockwise direction so that lug 40 enters the recess 41 and latches thekeyina lowered position. During this movement, the spring 42 causes the trip arm 27 to be moved clockwise so that its lower edge 37 is now aligned with the bail lug 35. If the key is again depressed, the bail 32 is moved back to its original position and, through the spring 42, causes the trip arm 27 and key also to revert to their original positions Release of the latched down key may be effected without a second depresson of the key by operation of the bail 32 by external means. Such release of a latched-down key e.g. a caseshift key of a typewriter, is often effected by depression of a second key. The key acts upon a leaf spring 48, Fig. 2, attached to a pin 50 and contacting the operating member 13 of the switch 11 so that a mechanical advantage is obtained without an unduly large force being exerted on member 13
