Patent GB-851879-A (GB)
Abstract: 851,879. Drafting-apparatus. DIXON CORPORATION. March 6, 1958, No. 7245/58. Class 120(2) [Also in Group XXXIV] Drafting-apparatus comprises a pair of front rolls, at least two pairs of rear rolls, the ends of the top rolls of which are maintained in alignment by guides, the top front roll comprising an arbor between a pair of spaced cots which is held by means positioned from one of the rear top rolls, the arrangement being such that the fore-and-aft location of the mid-point of the arbar is determined only by the geometry of the arrangement and in operation the front top roll and the arbor are free to adjust into alignment with the front bottom roll without interference from other rolls. The forms shown have two pairs of rear rolls, the upper rolls each having two spaced cots and the lower rolls running through the length of the machine: the upper rear rollers are positioned by pivoted guides 24 engaging their trunnions. The saddle 26 by which the top bars are weighted is in two parts: the rear part 38 is in the form of a stamping with inturned edges gripping bearing-blocks 55, 56 engaging the necks of the upper rear-rollers, while the front part 37 is curved to embrace a ball bearing on the arbor of the top front roll which is held in place by a spring 47 which holds the outer race stationary. In Fig. 1, the invention is applied to a system having a Casablancas unit 17 supported on the middle rollers: the front part of the saddle 26 is supported on the back part by a ball-and socket connection 59 of which the two units are adjustably carried in slots. The weighting stirrup is carried in the neck 43 of a bolt adjustably screwing into a projection 39. In Fig. 13, the invention is applied to a Roth system: the weighting stirrup is pivoted at 87 to the front part of the saddle 37, both parts of the saddle being slotted to receive it. The middle rolls are weighted through a member 79 fixed to a bar 76 between sides 77 with recesses hooked over the shaft of the top roll. The bar 71 of the lower unit runs through the length of the machine. The ball-and-socket connexion is slightly different in form from that of Fig. 1 and is also slotted to allow the stirrup to pass through. The trunnions of the middle rollers may be pivoted with bushes 90, Fig. 7 of anti-friction material which snap into recesses 93 in the cots, grooved flanges 95 being pivoted to engage the side-walls of the Casablancas unit 17. In the case of the front and back rollers the bushes are grooved to receive flange 961 Fig. 9. The outer surfaces of the bushes may be roughened or shaped to be held stationary while the roll-arbors rotate inside them. The front rollers may be cork-covered.

Title: Radiation hardened circuit
Inventor: GUPPY DAVID JOHN
IPC: G11C11/00
Filed: 1986-04-24
Abstract: Computer memory can be hardened against nuclear radiation but the data in the memory is only safe while the memory is not being accessed. Data can be copied to three separate memories in sequence so that, even if a nuclear event occurs during a changeover from one memory to another, at least the third remains safe. However, three separate memories is a significant hardware penalty. Herein, there is proposed the use of two memories (1 and 2) and a memory select changeover switch incorporating a resistance/capacitance control network (15 to 18, 21 and 22), arranged both to introduce a 'safe' period between memory selections (during which neither memory is selected) and also to memorise and reproduce its previous switch state following a nuclear event. <IMAGE>
