Title: A typewriter escapement mechanism
IPC: B41J19/58
Filed: 1965-11-05
Abstract: 1,074,563. Typewriters. OLYMPIA WERKE A.G. Nov. 5, 1965 [Nov.17, 1964], No. 46988/65. Heading B6F. Letter-spacing.-One or two units of letterspacing may be selectively employed by disconnecting one of the pawls of an alternate detent escapement device. In normal operation an escapement operating member 5 is moved in the direction of arrow 13 and engages the end of either pawl 7, or 11 so the tooth 7 2  or 11 2  is pivoted away from a twounit toothed carriage rack 1. The pawl not engaged by a tooth, stops in contact with the rack and holds it after it has moved one unit of space. As shown in Fig. 1, pawl 7.is about to be pivoted and after release from tooth 1 1 , a spring pulls it to the right and it springs to engage the tooth 1 2 . If operating member 5 has not returned when the pawl 11 is moved to the left by the rack, member 5 may resiliently move with it. For two units of letter-spacing only one pawl, either 7 or 11 according to which happens to be available for operation is used. The other is disconnected by a rocker 9 positioned above the right-hand end of the pawls. As shown in Fig. 1, rocker 9 is pivoted about a pin 2 and when lever 8 is actuated, pawl 11 is moved away from the rack 1. Now when member 5 releases the operating pawl 7, there is no holding by pawl 11. Thus, pawl 7 springs back to engage the next tooth 1 2  and the carriage travels to effect two units of space. The pawl 7 springs back to the rack before the carriage movement since it has less inertia to overcome.

Title: Control arrangements for punching devices
IPC: G06K5/02
Filed: 1963-11-28
Abstract: 977,010. Selective punching. O. C. SELDEN. Nov. 28, 1963, No. 47029/63. Heading B4B. A punching device for punching information on a record carrier, such as a tape or card, comprises at least one punch which is operationally connected with a control switch to be operated when the punch has perforated the record carrier, the control switch being arranged in an electric circuit to indicate the operation of the switch. As shown, a record carrier 4 passed between a base-plate 2 and a matrix 3 is punched by a transverse row of punches 1, each of which when actuated by a member 7 to perforate the carrier depresses a spring 5 so that the free end of the spring makes contact with a fixed contact 8 to close an electric circuit and provide an indication that a hole has been punched. Each circuit may contain an additional switch which is closed when the information that a hole has been punched is fed into the device, the switch and control switch operating a relay to stop the device when the control switch has not closed. The switches and relays may be replaced by transistors. An additional hole position may be provided which is punched each time the information is represented either by an even number of holes or an odd number of holes, the control circuits associated with the punches being so combined that the operation of the punching device is stopped when the total number of holes in a transverse row is not an odd number or is not an even number respectively.

In the co-cultivation of Pseudomonas aeruginosa and Candida lipolytica in first and second fermenters, respectively, with recycle of culture liquors, biotin-related substances produced in the first fermenter are removed from the recycle liquor by adsorption prior to passing the liquor to the second fermenter wherein oil and fat, and citric acid are produced and subsequently separated from the recycle liquor.  In a similar procedure involving the cultivation of Corynebacterium hydrocarboclastus and Candida tropicalis, glutamic acid is produced in the first fermenter, and coenzyme Q and ergosterol in the second.

Abstract: 1362126 Sailing vessels BRITTON YACHT SYSTEMS Inc 2 Nov 1972 [2 Nov 1971] 50570/72 Heading B7V  A pair of wing sails has a common furling roller 10 which can be releasably secured to the deck in alternative positions allowing the sails to be used as wind sails or to be superimposed and used as a single jib or stay sail. As illustrated, the roller 10 is secured in its rearmost position for wing sail use. In operation, the lower ends of poles 12 and 13 are released from the life lines and the poles are lowered down the mast. The free ends of the poles are then secured to the clews 14 and 15 of the unfurled sails to give the wing layout as shown in Fig. 2. If the roller is secured in its foremost position 18 and the clews are secured together so that the two sails are superimposed, the arrangement functions as a jib sail, Figs. 4-7 (not shown). If the roller is secured in position 19, then the partially unfurled, superimposed sails function as a staysail, Figs. 8-10 (not shown).
