Title: Improvements in or relating to machines or mechanism for producing printing elements or typographical material
IPC: B41B5/12
Filed: 1928-04-28
Abstract: 316,346. Pierpont, F. H., and Lanston Monotype Corporation, Ltd. April 28, 1928. Single-type composing and casting machines; moulds.-Relates, to machines for producing printers' strip material in continuous or indeterminate lengths by additive or incremental casting in a mould, the open end of which is closed by the previously-cast element, and particularly to means for cutting such elements into lengths of accurate dimensions. The cutter is controlled by an adjustable counting or timing mechanism, the setting of which determines the number of casts made before the cutter is actuated, and gauging means is provided for determining the length of each cast. The timing-mechanism comprises an adjustable zero-stop A<1>, Fig. 4, which is handset by means such as a rotatable disc furnished with a toothed locking-device. The stop rests in the path of a travelling abutment A<6>, which is coupled with a ratchet-wheel A<8>, and is adapted to operate a pivoted trip-lever A<7>. The ratchetwheel is fed by a pawl A<10>, which is operated by a lever A<11>, A<14> from a rod A<15>, reciprocated through a yielding connection by means such as the metal-pump mechanism. The abutment A<6> is thereby advanced a step away from the zerostop A<1> at each cast, until it strikes and tilts the trip-lever A<7>. The pawl A<10> and the rod A<15> are thereby permitted to make a longer stroke than usual, whereupon the cutter is actuated. The cutter-blade B<8>, Fig. 1, slides in a block B" having a channel B<12>, through which the cast strip is advanced. The rod A<15>, when making its stroke, acts through a rod B<3> to insert an interponent b<1> between an abutment B<9> on a reciprocating driving-bar B<10> and a bridge-piece b<2> on a bar B<6> connected to the cutter, so that the next stroke of the bar B<10> operates the cutter. The length of the element cast is determined by adjustment of a rear stop or wedge E, Fig. 6, which arrests the mould-blade C in its backward movement. The wedge E slides on abutments E<13>, E<14> and is adjusted by means of a screw E<2> operated by a knob E<5>. A sliding bar E<6>, coupled with the knob and bearing an index mark, co-operates with fixed scales g', g<2>, and also with a scale E<12> on a ring E<9> attached to the knob. The wedge is held in adjusted position by a locking-device operated by a knob E<17>. If the length of the element to be cut off is not a multiple of the length of each cast, the wedge E is adjusted in accordance with a reading obtained from a movable scale coupled with the adjustable zero-stop of the timing-mechanism. Associated with the movable scale is a fixed scale, the divisions of which represent various numbers of units, which require to be distributed over the several casts making up the severed strip.

Title: Improvements in or relating to electric generators
IPC: H02K44/20
Filed: 1933-05-02
Abstract: 414,851. Generating electricity by forcing fluid through magnetic fields. KRAMOLIN, L. L. DE, 52, Babelsbergerstrasse, Wilmersdorf, Berlin. May 2, 1933, No. 12769. Convention date, May 3, 1932. [Class 35.] In a generator in which a fluid such as a vapour, gas or an electrolyte, is forced through a magnetic field, the current is obtained from the streaming fluid by means avoiding losses due to the effects of back electromotive force, contact resistance or the like occurring at the boundaries of the current path in said fluid. As shown, the electromagnet has a centre pole 17 connected by limbs 18 and ring 19 to the outer pole 16 which has slots 23 carrying coils in which alternating-current is induced when mercury vapour from the boiler 1 is passed through the annular magnet gap into the condensation chamber 5, this chamber being connected at 21 to a vacuum pump. A periodical variation of the magnet strength is obtained by connecting a condenser 26 in the excitation circuit but in addition or alternatively the speed of the fluid may be periodically varied by mechanical devices in the mouthpiece 4. The current may be of high frequency. In an alternative arrangement, the magnet poles are external to the chamber 5, the neck of which contains a cold electrode and a cathode heated by a battery or from subsidiary electrodes and in this arrangement electrodes of metal or carbon are used and they may be activated for example by a barium compound. This alternative arrangement is intended for continuouscurrent output but it is stated that by constructing both electrodes as emitters, alternating-current may be obtained. The parts of the apparatus which do not need cooling may be insulated against loss of heat. Fluids other than mercury, such as sulphuric acid, may be used and the electrodes may act electrolytically therewith so that the charges accumulated may be effective in subsequent periods to augment the generated E.M.F.
