Title: Improvements in apparatus for indicating the score in the game of darts or for any similar game or contest
IPC: F41J3/02
Filed: 1937-11-12
Abstract: 505,577. Scoring-apparatus for games. GLENN, J. J. Nov. 12, 1937, No. 31157. [Class 132 (ii)] A score-indicator, particularly for the game' of darts, comprises a shallow casing in which are mounted a number of rectilinearly movable slides each marked with consecutive numbers and having manually operable pointers movable adjacent to fixed scales corresponding to units, tens, hundreds, &c., the casing being provided with a window or windows so disposed in relation to the slides that required initial and succeeding scores are indicated therein according to the positions of the slides. As shown in Figs. 1 and 2, the scores required by opposing players are indicated at windows e by the adjustment of pointers f over stationary scales g, h, i designating units, tens and hundreds respectively. The pointers, are attached to number-bearing slides a, b, c passing behind windows e. The device is shown in readiness for a game of 301 points, as permanently indicated at a window m. The same number of points is initially indicated at the windows e by the presentation of the number 11 at the digit windows. As scores are made the pointers f are correspondingly moved to make the deduction from the previous score and show the reduced total required at the wndows e. The number displayed at the window m is carried on a slide n which also carries the scales i. The slide n also carries, in addition to the number 301, other initial scores such as 101, 201 &c.up to 1001 and any one of these initial numbers may be brought into view at the window m by moving the slide by means of a finger piece o. The same movement brings into view the relevant hundreds figures on the scales i. Pins l on the slide form zero abutments for the hundreds pointers f and facilitate the setting of the appropriate hundreds digits at the hundreds windows e. In a modification, Fig. 4 (not shown) the device is made for one player only, the window m being omitted and the scale i being fixed. In a further modification, for two players, Fig. 5 (not shown), the hundreds and tens scales are combined in one fixed scale over which the pointer of a combined hundreds and tens slide may be moved, the units scale and slide being similar to those described above. In a further modification, for two players, Fig. 6 (not shown) the slides of each set are arranged in line, the sets being one above the other and the pointers of the two sets being directed towards each other.

Title: Improvements in or relating to a method and device for multiplex transmission by means of time modulated pulses
IPC: H04J3/00
Filed: 1950-12-21
Abstract: 682,648. Multiplex pulse signalling. POTIER, G. X. N. Dec. 21, 1950 [Feb. 7, 1950], No. 31179/50. Class 40 (v). In a multiplex pulse interval modulation system transmitter measuring and storing circuits 107-109 simultaneously measure at equal intervals T by using analysis pulses from a synchronizing pulse generator the instantaneous value of unidirectional signals from channel DC restorers 104-106 and store the said values for an interval T. The values then modulate in turn pulse position modulators 112 &c. connected to receive pulses from a sync. pulse generator through a delay line 111 and interconnected in cascade by delay networks 115, 116, &c. to space channel pulses by a small interval even in the absence of modulation. The modulators may operate by producing and differentiating duration modulated pulses. The network 111 has a tapping applying an analysis pulse to the storage circuits 107 &c. only after the latter are simultaneously reset to zero at intervals T by a pulse from the generator 110, and delays the pulses fed to the first modulator 112 to allow time for measurement by the circuits 107 &c. At the receiver the channel pulses are applied to the first of a series of flip-flops 120 connected in cascade with outputs corresponding to each channel. The outputs of the flip-flops are constant amplitude pulses of durations corresponding to the intervals separating adjacent channel pulses, and are applied to measuring and storing circuits 122-124 integrating them to derive corresponding values of voltage, the circuits 122 &c. being reset to zero at intervals T by delayed pulses from the synchronizing pulse selector 119. The stored voltages are applied to modulate, in amplitude or duration, pulses from the synchronizing pulse selector 119 in modulators 126-128. The latter pulses are then demodulated to derive the signals. The D.C. components corresponding to the initial separation of the transmitted pulses in the absence of modulation may at the receiver be removed by a transformer or capacitor. Specifications 594,566, 610,774, 628,555 and 665,755 relating to pulse communication are referred to. Specification 535,384 also is referred to.

Title: Improvements in and relating to surface measuring machines
IPC: G01B5/26
Filed: 1920-11-09
Abstract: 153,868. Krupp Akt.-Ges., F. Nov. 13, 1919, [Convention date]. Area meters.-In machines of the Sawyer type for measuring the area of leather &c., means are provided for automatically correcting the zero position of the indicator during the re-setting of the machine. The roller C over which the leather sheet is passed is geared with the shaft B carrying the usual co-axial ratchet wheels b<2> by either of two trains of gearing b<7>, b<8> producing opposite rotations of the shaft B and controlled as to operation by a clutch b<6>. The measuring bands d<2> d<3> connected at one end through sun-and-planet gearing with the indicator disk d<4> are secured at the other to a non-rotatable screwed bolt G mounted in a correspondingly screwed sleeve G' adapted to be rotated in one or other direction by a clutch sleeve g<3> and gearing g<4>, g<5> driven from the machine through a chain h<3> and shaft J. A cam N is mounted loosely on this shaft and is rotated from shaft B through a clutch i<2> controlled by a hand-lever P. When it is desired to reset the machine, the lever P is moved in the direction of the arrow V so as to shift the clutch i<2> and cause the cam N to rotate and through a pair of pivoted spring-controlled arms R, T to throw the clutch b<6> so as to reverse the rotation of shaft B. The bands d<2>, d<3> thereupon unwind and the disk d<4> returns to its zero position, or approximately so. The cam N, through a roller m<8> and link m<6>, now rocks a lever MM<1> and if the disk d<4> is not in its correct zero position an arm d<6> thereon is engaged by one or other of two bell-crank levers m<3>, m<5> pivoted on the lever MM' at a slight distance apart and connected with the clutch sleeve g<3> by links k<4>, k<5>. The bell-crank lever thus engaged rocks and shifts the clutch g<3> so as to effect the rotation of the sleeve G' in one or other direction to raise or lower the bolt G. Consequently the bands d<2>, d<3> are either pulled or slackened until the disk d<4> assumes its exact zero position, the bellcrank lever then being freed and the clutch g<3> allowed to return to its inoperative mid position under the influence of a spring a<1>. Simultaneously with the rocking of the lever MM<1> the cam N again rocks the arms R, T to return the clutch b<6> so that the shaft B resumes rotation in its original direction. Near the end of the rotation of the cam N a pin n<6> engages an arm of the lever P, so as to throw it over to withdraw the clutch i<2> and stop the rotation of the cam. The final movement of the latter into its normal position is effected by the pressure of an arm p<1 >of the lever P on a flat n<5> formed on the cam, this pressure being derived from a spring q<1> which through a bell-crank lever Q and roller q<2> exercises a snap action upon the lever P.

[Class 136 (i)] In cycle &c. brakes of the type in which a pair of two-armed levers carrying the brake blocks are actuated by a rotary cam arranged between their ends, the cam and /or the cooperating surfaces on the levers are so shaped or arranged as to compensate for the tendency of the cam to rock one lever more than the other, due to the fact that the cam acts on the two levers at different distances from their respective fulcra. A supporting-plate 10 secured to the cycle frame is apertured to receive screw studs 11 receiving nuts 13 and acting as pivots for two levers 14, 15, the lower ends of which carry adjustably-mounted brake blocks 17 and the upper ends of which are acted upon by a rotary cam 24, which is pivoted on a stud 26, 27 screwed into the plate 10 and is provided with an outer plate 32 having an arm 33 connected to a Bowden wire &c. transmission 34. In order to equalize the action of the cam on the two levers, the cam 24 is off-set to the left on its pivot stud, as shown; or the same effect may be obtained by suitably shaping the co-operating surfaces of the cam and levers. The parts of the brake are located in the off position by flat &c. interengaging surfaces on the cam and levers. The levers are retracted by a spring 38 attached to posts 36, which are fixed to the upper ends of the levers and pass through slots in the plate 10. The lower ends of the legs of the plate 10 are provided with bent-over lugs 39 which guide the levers 14, 15.
