Title: Improvements in or relating to straight-bar knitting-machines
IPC: D04B7/04
Filed: 1924-06-30
Abstract: 228,739. Innes, Henderson, & Co., Ltd., Bell, T., and Huggan, R. June 30, 1924. Straight-bar machines.-To facilitate the production of diamond check patterns, a treadledriven machine with a single row of sliding latch needles is provided with two sets of carriers 2<b>, 3b mounted on bars 2a, 3a sliding on rods 2, 3 between stops 6 .. 9. The stops 6 .. 9 slide on the bar 3 and the stops 7, 8 on the bar 2. The stops 6, 7 are connected together by a yoke 4 and the stops 8, 9 by a yoke 5. The yokes are formed with ratchet teeth 10, 11 engaged by pawls 12, 13 operated simultaneously by hand levels 14, 15 to slide the yokes 4, 5 to the left and right respectively. By this means the amount by which the carriers 2b, 3b, can be traversed is respectively increased and diminished by two needle spaces per course, thus enabling one-half of a row of diamond checks to be made. When the stop 8 reaches the limit imposed by an adjustable stop 17 the pawls 12, 13 are reversed, further operation of the handles 14, 15 diminishing and increasing respectively the traverse of the carriers 2b, 3b until the remaining portions of the row of diamond patterns are completed. The carriers are traversed by hand.

Title: Improvements in or relating to Electric Contacting Devices.
Inventor: HEAP ARTHUR CECIL
IPC: G01S1/72
Filed: 1918-05-15
Abstract: 129,752. Heap, A. C. May 15, 1918. Variable resistance transmitters.-In eletric contacting devices particularly for use on fixed or movable buoys or mines floating on or submerged in water and actuated by sound waves transmitted through the water. and in which one of the contacts is carried by a hollow body or float immersed in a liquid, the contacts separating when the device works, the effects of temperature changes are compensated by suitably proportioning the volumes and air pressure in the float and the casing in which the air &c. are contained, the end faces of the float being in the form a diaphragm, one of which carries a contact. In another arrangement in which a float 10 slightly denser than the liquid in which it is immersed rests on a diaphragm 5 the contacts being on the float and diaphragm, the latter is placed on a chamber 3 having an air space 6 above the liquid; the pressure in the chamber 3 and in the casing 1 is balanced by a pipe 7. In a modification of this arrangement, an air space is left in the casing and the inner chamber and diaphragm are replaced by a thin walled chamber which acts as the sensitive member. Instead of making the float of greater density, it may be of less density than the liquid in which it is immersed, and then be arranged below the diaphragm. The end walls of the float may be concave instead of convex, as shown, and the ends may be of different thickness.

Title: Improvements relating to weighing apparatus incorporating a self-balancing potentiometer system
Inventor: CHILTON JOHN MOORHOUSE
IPC: G01G23/365
Filed: 1960-03-09
Abstract: 911,348. Electric selective signalling systems. AVERY Ltd., W. & T. May 8, 1961 [May 9, 1960], No. 8241/60. Class 40 (1). A voltage digitizer of the type in which the unknown voltage is repeatedly compared with a known voltage, the result of each comparison being used to control the selection of the next known voltage, is characterized in that the known voltage is produced by selecting appropriate tappings on the secondary winding of a transformer. As described, an unknown weight is converted into an unknown voltage by a potentiometer P1, and the unknown voltage is applied to a comparing arrangement A, RL1. A known voltage, produced by rotary switches S1, X; S2, Y; and S3, Z ; and. a transformer T1, is applied to the other comparator input. Prior to a digitizing operation all three switches S1, S2, S3 are in their zero positions so that the known voltage (zero) will be less than the unknown voltage and as a result the comparator will close a contact P as opposed to a contact Q. Depression of a key PB will then initiate a cycle of operation which proceeds under the control of a sequence control switch S4, as follows: (1) Depression of key PB causes the control switch to advance to its No. 2 position. (2) With the control switch in its No. 2 position its bank S4C applies a negative voltage to switch S1 via closed contact P. This causes the switch S1 to advance contact X increasing the known voltage by increments of one hundred. The known voltage actually applied to the comparator at this stage of the digitizing sequence is the voltage selected by contact X increased by one hundred by a resistor R8 and a bank S4D of the control switch. Thus, when advance of contact X stops, which occurs when the known voltage applied to the comparator exceeds the unknown voltage and contact P opens and Q closes, the actual setting of switch S1 will correspond to the hundreds digit of the unknown voltage. Closure of contact Q causes the control switch to advance to its No. 3 position via its bank S4B. (3) The resistor R8 is taken out of circuit so that the known voltage drops by one hundred and contact P again closes. Switch S4 advances to its No. 4 position by virtue of the negative potential applied direct to its No. 3 contact of bank S4B. (4) to (6) The tens and units digits of the unknown voltage are determined in a similar way to the hundreds and the control switch advances to its No. 7 contact. (7) A resistor R11 is switched into circuit which increases the unknown voltage by unity, thereby causing contact Q to close and advance of the switch S4 to contact 8. (8) A resistor R12 is switched into circuit which increases the known voltage by unity and causes contact P to close. These last two stages (7) and (8) act as a check on the previous six stages.
