Filed: 1918-02-14
Abstract: 118,833. Schleifer, R. Sept. 1, 1917, [Convention date]. Combing-machines.-The lap 6 is fed forward by a feed-device 5 and passed between the open jaws 1, 2 of one of a series of nippers mounted on an intermittently rotating carrier 3. An oscillating blade 7 assists in placing the end of the lap between the jaws. The jaws grip the lap, combs 9 enter it to hold it, and the rotation of the carrier 3 tears off a tuft. The projecting end of the tuft is carried past two or more combing- drums 10, 11, which comb both sides of it. The tuft is transferred to another gripper 1<1>, 2<1>, forming one of a series mounted on another carrier 3<1> rotating synchronously with carrier 3. The uncombed end is then treated by combing-drums 10<1>, 11<1>, and finally the fully combed tuft is passed to a drawing-off device 15, the belt 14 of which rotates intermittently. A stroke 17 draws the tuft from the opened jaws on the nipper. The ends of the tuft may be treated by more than two combing-drums, and more than two series of nippers may be employed. The various operations may all be effected automatically or by hand.

Title: Improvements in ball point writing instruments
IPC: B43K24/02
Filed: 1948-01-29
Abstract: 648,605. Reservoir pens. PARKER PEN CO. Jan. 29, 1948, No. 2697. Convention date, Jan. 31, 1947. [Class 146 (iii)] A ball pen comprises a telescopic casing and a writing unit including an ink reservoir and ball writing point mounted therein, the arrangement being such that the ball point is projected beyond the casing when the latter is expanded and is retracted into the casing during contraction of the latter. The outer casing consists of two telescopic parts 1, 2. The part 1 comprises a tube 3 open at its rear end and having a tapering part 4 detachably screwed thereto at the other end. The part 2 consists of two tubes 10, 11 between which the tube 3 slides, and which are secured together by an end piece 15. A tongue 13 on the tube 3 slides in a slot 12 in the tube 11 to prevent relative rotation of the parts. Within the tube 3 is rotatably and slidably mounted a sleeve 40 in which the pen unit is removably and frictionally held. A tongue 50 on the tube 11 engages a cam slot 51 in the sleeve 40 so as to cause rotation of the sleeve as the parts 1, 2 are moved relatively to one another. Another cam slot 56 in the sleeve 40 and of much smaller pitch is engaged by a pin 52 on the part 1 and causes the sleeve 40 to move axially to project the ball point 25 as the casing is extended and to retract the point when the casing is shortened. The arrangement is such that pressure on the point during writing does not cause relative movement of the parts. The pen unit consists of a reservoir barrel 21 tapered at one end 23 and fitted with a tip 24 having a socket 25 for the ball 26 and an inkfeed duct 27. At the other end the barrel 21 has a flared neck 32 fitted with a vent plug 31. Leakage of ink and contact therewith of air is prevented by a flexible sac 30 which has its open end connected to the neck 32 and is collapsed when the reservoir is full. The sac may be of resilient material tending to return to expanded condition so that it applies slight pressure to the ink. Alternatively, a limp sac may be employed. Specifications 602,088, 602,101, 624,366 and 633,880 are referred to.

Abstract: 569,493. Piezo-electric crystals. BRUSH DEVELOPMENT CO. March 7, 1942, No. 3009. Convention date, March 8, 1941. [Class 40 (v)] Piezo-electric crystals are provided with water - proof coverings which are arranged so as to reduce the risk of the coverings being rendered ineffective due to bending the leads which pass through the covering. In Fig. 7 a bi-morph crystal comprising elements 40, 41 has an internal electrode 42 connected to a lead 28 and an external electrode 43 made of tinfoil wrapped round the two elements and connected to a lead 29. An insulating cap 45 is applied to the end of the element followed by a metal protective cap 46 which bends the leads down.across the end of the crystal and round the edge of the cap as shown. The whole assembly is now coated with a waterproof substance 47 which builds up fillets at positions such as 48, 49 thus strengthening the parts most liable to damage. Also if the coating is broken due to bending the leads, the leakage. path for moisture is long and sinuous. In a modification (Fig. 8, not shown), the electrodes are made to finish short of the end and no insulating cap is needed. In other modifications (Figs. 9 and 10, not shown) the element is dipped in waterproofing material, both before and after bending the leads. Series connected crystals are also described (Figs. 12- 14, not shown). The crystal arrangement may be used in the piezo-electric record cutter described in Specification 568,881.
