Title: The control of a textile processing machine
Inventor: CATLING HAROLD
IPC: D01G31/00
Filed: 1963-11-14
Abstract: In the automatic control of a series of fibre-processing machines comprising a card and three drawing frames through which a sliver, web or lap passes successively, a measured length of sliver issuing from one of the frames is collected and coiled into a can or wound on a reel and weighed on a balance.  Deviation of such weight from a predetermined standard, tilts the balance arm to produce an electrical or mechanical signal which actuates a closed- and/or open-loop servo-system to adjust correctively the speed differential between the back and front rollers of the same and/or preceding and/or succeeding drawing frame so that the final output of the series has a constant desired mass per unit length. The weight deviation may be recorded capacitatively, magnetically or by punch-card, and such record may be used to initiate the control.  It is stated that operations of doffing each can, weighing and adjusting a frame may be effected manually.

[Also in Division G4] In a system for the automatic dialling of telephone numbers, a card is inserted in a scanning device to cause transmission of a series of pulse trains to a telephone exchange. The card has printed circuit connections between contacts on its lower and upper edges, contact K9<SP>1</SP> being connected directly to contact Kro and each of contacts K0<SP>1</SP>-K9<SP>1</SP> being connected, through diodes, if necessary, to a combination of contacts K1-K5. When the card is inserted, RO pulls up to start impulsing relays IG, A and to supply positive voltage to the rest of the system. With switch Z in the " 0 " position, a combination of relays 1-5 is connected in series with ZR and these relays pick up. A contact decoding tree of relays 1-5 connects P to one contact of switch S, and a contact zr connects the stepping magnet of S to an impulsing contact ig. When the S wiper reaches the contact connected to P through the tree, P picks up, p4 closes and pulses are transmitted to the exchange over lines a, b. When wiper S reaches contact 11, C picks up and P drops out, ending the first digit transmission. S then continues to the home position and in doing so steps switch Z to position 1. The process is repeated for the remaining digits. When switch Z reaches contact 9, B picks up and closes b 2  to notify the exchange that transmission is complete.

Title: Continuously foamed vinyl aromatic polymers directly from their monomer
IPC: C08J9/14
Filed: 1963-11-27
Abstract: Foamed polymers are obtained from monomeric monovinyl aromatic hydrocarbons by continuously introducing the monomer with an organo-metallic catalyst and a blowing agent into a reactor, heating to at least 100 DEG  F. under a pressure above 500 lb./sq. in. for at least 10 minutes, and continously venting the reactor to allow the foam to escape.  The monomer, particularly styrene, may be copolymerized with other monovinyl aromatic hydrocarbons.  The catalyst is preferably an alkyl lithium, e.g. ethyl-, n-butyl- and isobutyl-lithium, but alkyl and aryl alkali metal compounds may also be used.  The blowing agent may be a volatile compound or a gas. Examples of the former are C4- 7 alkanes.  The gas, e.g. H2 or N2, may be pumped into the reactor after polymerization and dissolved in the polymer melt.

In an embodiment (Fig. 2) the insulating body 1 has three rows of chambers 2, and a mounting flange 6. The contact member 7 (Figs. 4, 5) has two resilient contact arms 8 joined by a bridge 9 and a termination section 10 for receiving conductor 11. Contact portion 23 and locking tab 13 are separated by slot 12, and tab 13 has a releasing shoulder 14 which has a ramp 15. The contact 7 fits. into chamber 2, which has a substantially rectangular cross section and an edge 16 which limits the upward movement of contact. 7. Wall 3 has a locking shoulder 17 which occupies about a third of the width of chamber 2. A passageway (18, Fig. 1, not shown) defined by wall 41 and shoulder 17 receives the releasing shoulder 14 of locking tab 13. Wall 3 has a slot raised portion (19) extending from shoulder 17 to the upper edge 16 and a stop 20; the portion (19) holds contact arm 8 away from wall 3 to define passageway 25 for insertion of contact removing tool 22 and stop 20 engages by faces 8a to limit upward movement. To release contact member 7 from the upper side (Figs. 2) tool 22 is inserted through passageway 25, tab 13 is lifted from shoulder 17 and contact 7 removed by withdrawing conductor 11; to release contact 7 from the other side tool 22 is inserted through passageway (18) and pushed under the shoulder 14 to release tabs 13 and the contact 7 is removed as before. In a modification (not shown) the chamber has another locking shoulder on wall 3<SP>1</SP> and the contact 7 has two locking tabs 13 and contact 7 can then be inserted in chamber 2 in two positions, angularly displaced by 180 degrees about the longitudinal axis of contact 7; the removing tool in this case (not shown) is fork-shaped to release both tabs 13 simultaneously.

A movable carrier 63 is associated with each carrier 20, the carriers 63 each bearing an opaque sheet on which a plurality of slots of different widths are cut out. The carriers 63 are movable via stepping mechanism controlled by solenoids (33, 34) Fig.3 (not shown), to position a selected slot beneath a slot 20b in a cover member 20a of the associated carrier 20. Roller blind mechanisms 23 on each carrier 20 are rolled up/unrolled as the carrier 20 moves, the mechanisms preventing the projection of more than one line image, or representation. One of the carriers 20 is positioned to provide vertical lines, the other horizontal lines. Alternatively, one of carriers may support lines of text to be imaged.
