Title: Improvements in and relating to retractable ball-point pens
IPC: B43K24/08
Filed: 1958-04-11
Abstract: 849,949. Reservoir pens. KREUTZER, R., and WEISMULLER, G., [trading : as STAEDTLER, J. S. [Firm of]]. April 11, 1958 [July 19, 1957], No. 11618/58. Class 146(3). In a retractable ball-point pen with a plunger-actuated, return spring-loaded writing unit in which the projected and retracted positions of the writing unit are determined by at least one ball, the writing unit and a guide tube therefor perform a slight rotary motion with respect to the barrel at each operation of the plunger and for this purpose the ball rests within a recess in the guide tube, the return spring is located between an abutment on the guide tube and a sleeve inserted in the barrel and the ball co-operates with oppositely directed control recesses and teeth provided in two bushes associated with the sleeve. The rear end of the writing unit o is received in an axially slidable guide tube l, an extension z of which frictionally grips the unit. The barrel of the pen consists of two parts a b fastened together by an externally threaded sleeve c. Slidable in the rear end of the barrel part b is a plunger g to the forward end of which is fastened a pressure sleeve i having an inturned flange m at its front end. The pressure sleeve i is slidable over the enlarged rear end k of the guide tube l, the flange m abutting against a shoulder n thereon. A spring t bears against the flange m to bias the guide tube l and writing unit o towards retracted position. Bushes r, s, having cam faces as shewn in Fig. 4 are fixed to the inner surface of the sleeve c. Three balls q are carried in recesses p in the guide tube l and cannot move either circumferentially or longitudinally in relation to the tube. When the balls q are engaged in the recesses B of the bush s the writing unit is retracted. Pressure on the plunger g first relieves the guide tube l of the rearward bias of the spring t, and then, when the plunger has travelled forwards a distance A, urges the guide tube t and writing unit o forwards until the balls q engage inclined cam faces c on the bush r, which engagement partially rotates the parts l, o. Release of pressure on the plunger allows the parts l, o to be carried back by the spring t until the balls q engage inclined cam surfaces E on the bush s and come to rest in recesses F, the writing unit then being in projected position. A further depression of the plunger restores the unit to retracted position, the unit being rotated slightly relatively to the pen barrel at each actuation of the plunger. In a modification, Fig. 2 (not shown), a helical spring may be interposed between the guide tube l and its gripping extension z so that the writing unit yields resiliently in writing position.

Abstract: 468,848. Colour photography. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) Jan. 14, 1936, No. 1198. [Class 98 (ii)] In the silver bleaching-out dye process, a hydrosulphite in the form of a stable condensation product with an aldehyde or ketone is used for destroying the dyestuff at the places where silver has been formed.

Abstract: 304,772. Waygood-Otis, Ltd., (Assignees of Handy, A. E.). Jan. 26, 1928, [Convention date]. Charging. - In a blast furnace 11 having at its upper end superposed charging-hoppers 12, 13 closed by large and small bells 15, 14 respectively, the bells are actuated by a single driving device which is so arranged that, when either of the bells is opened, the other remains closed. The bells are suspended from one end of the usual pivoted levers 17, 23, the other ends of which carry counterweights 21, 24, and are attached to ropes 39, 40 passing over fixed pulleys 35, 36, 41, 42. The ropes 39, 40 are secured at their lower ends to lengths of chain 33, 37 which are secured at 34, 38 respectively, to drums 26, 27 loosely mounted on a shaft 28, the arrangement being such that when the connecting-pins 34, 38 are in their uppermost position the bells 14, 15 are closed, while the latter reach the fully open position when the pins have rotated through approximately 270‹. Rigidly mounted on the shaft 28 between the drums 26, 27, is a driving-member 43 carrying lugs 44, 45, the latter being arranged one on each side and adapted to contact with projections 46, 47 on the drums 26, 27. As shown in Fig. 5, the arrangement is such that, on rotation of the member 43 in a clockwise direction, the drum 27 only is rotated, the lug 44 moving away from the projection 46 and the bell 14 therefore remaining closed. On reversing the rotation of the member 43, the bell 15 closes under the action of the weight 24 and, on engagement of the parts 44, 46, the drum 26 rotates, in an anti-clockwise direction, to open the bell 14. The member 43 is driven through gearing 53, 54, 58 from an electric motor 48 fitted with a reversing-switch 49, Fig. 1, a brake 60, spring applied and electrically released, being provided for rapidly bringing the member 43 to rest when the motor is switched off. When it is desired to have both bells 14, 15 open at the same time, the former is opened and the chain 33 engaged with a fixed hook 29, whereupon the motor 48 is reversed to open the lower bell 15.

The fuel reservoir a is arranged in a water bath b which is filled with boiling water at starting but is afterwards maintained hot by the combustion gases passing through the chimney' d. The fuel passes from the reservoir a through a jacketed needle-valve g to the spiral channel s in which it is partially burnt with air drawn in through regulatable openings x<1>-x<4> in the top of the stove. The resulting combustion products pass into the tuyere rand are mixed with air drawn from above the stove through pipes p<1>-p<4> so as to effect complete combustion. The entrances to the pipes p<1>-p<4> are regulated by means of obturators o<1>-o<4> carried by a collar n which is turned on the chimney by a link m connected to a nut k on a hand-operated screw j. The screw j also carries a worm i engaging a worm-wheel h on the spindle of the needle-valve g so that the fuel and air supplies are regulated simultaneously. The fuel reservoir is shown fitted with an' air-tight lid f and an air-tube e but, alternatively, it may be supplied through a constant-level device similar to that shown at c for the water-bath b. The apparatus is heated sufficiently to initiate combustion by means of wood chips &c. moistened with petroleum placed on a grate y in a box u at the base of the stove. Regulable air conduits v<1>-v<3> passing through the box u terminate below the grate y.

[Also in Divisions A6, B3 and B5] In securing a net to one or more handles or like supports the net is extended over a surface on which the supports or handles are laid so as to cover the latter and cooperating net clamping parts are secured over said supports or handles with the interposition of net sections, which are thus clamped tightly betwen said co-operating parts and the handles or supports, any excess area of the net being finally cut off. Fig. 3 shows netting 2 secured to a handle or support 6 by clamping the netting between bearing surface 8 of the support 6 and a co-operating clamping part 7, the latter being secured by rivets, screws or bolts 9. The surface 8 may be serrated, grooved, provided with a series of bosses or otherwise roughened, the surface of the part 7 being correspondingly shaped. Adhesive may also be used to assist in securing the netting. Figs. 13, 14 show means for manufacturing several articles simultaneously by the method of the invention. Several handles 13, 13<SP>1</SP> are placed in suitable recesses in table top 16 and netting is positioned over the table top from an adjacent roll. The top 16 has studs 17 and 18 for accurately positioning the net. After the netting is in position co-operating clamping parts 7, 7<SP>1</SP> (right hand end of Figs. 13, 14) are placed in position and secured to the handles. The netting between the articles is then cut so as to remove the unwanted material. Other embodiments show a continuous process in which single articles are produced on individual frames each being passed in turn to a suitable riveting head and a continuous process in which several articles are produced simultaneously on suitable supporting frames. The meshed net may be of textile, plastic or metallic material and the handles may be of metal, wood, plastic or paste-board. Fig. 12 shows an article suitable for projecting a ball and comprising netting 2 secured to handles 13, 13<SP>1</SP> and having elastic threads 15, 15<SP>1</SP> stretched between the handles. The invention may also be applied to fishing and hunting nets, net bags &c., and hammocks.
