Title: Improvements in writing instruments
IPC: B43K27/08
Filed: 1948-09-07
Abstract: 655,804. Reservoir pens. JOVANOVITSCH, P. Sept. 7, 1948, No. 23563. Convention date, Sept. 9, 1947. [Class 146 (iii)] A multiple writing instrument having two writing members comprises a nib 3 and ball point 4 provided with ink containers 6 and 7 of semi-circular cross-section mounted within a casing 1 so as to allow of projection or retraction of either container, the aperture 2 in the casing 1 through which the writing members pass into the writing position being of the same size and cross section as one container. The movement of the containers is effected by two helical grooves 10 and 11 and two pairs of annular grooves each pair of annular grooves extending through 180 degrees and being joined together by a longitudinal groove engaged by a ball which on rotation of a bush 12 surrounding the two rear ends of the containers 6 and 7 causes alternately a longitudinal movement as well as an exchange of place within the casing 1 of the two containers. The helical grooves 10 and 11 are formed in the rear ends of the containers 6 and 7 and cooperate with a ball 21 fixed in the bush 12 which is rotatable but axially secured in the casing 1. The forward ends of the containers 6, 7 are provided, respectively, with longitudinal grooves 13, 14 and annular grooves 15, 17 and 16, 18, while balls 19 and 20 secured in the casing 1 guide the containers longitudinally. When the bush 12 is rotated through 180 degrees counter clockwise the containers 6 and 7, whin the positionn in Fig. 1, are preventedwohn es from rotating by the ball 20 engaging the groove 14 so that the container 6 is projected longitudinally. Clockwise rotation of the bush 12 causes retraction of the container 6 until the groove 17 is opposite the ball 19, further rotation causes rotation of the two containers in the casing I and ultimately projection of the container 7. The container 6 is filled by a piston 23 having a screwed piston rod 22. Two reservoir pens with nibs or two ball point pens may be provided instead of one of each as shown. The Specification as open to inspection under Sect. 91 states that grooves 10 and 11 may be formed in the bush 12, while the grooves 13-18 may be formed in a bush fixed to the casing 1 in which case the balls 19, 20 and 21 are secured to the containers 6 and 7. This subject-matter does not appear in the Specification as accepted.

Title: Process and machine for printing strips of flexible, particularly textile, material
IPC: B41F15/08
Filed: 1953-08-26
Abstract: 742,961. Stencilling-apparatus. KERAG KESSELSCHMIEDE APPARATE-UND MASCHINENBAU. Aug. 26, 1953, No. 23611/53. Class 100 (2). A process for the repeat printing of strips of flexible, especially textile, material comprises laying the material under constant tension and in a frictionally tight manner for at least 180 degrees around the surface of a rotatable cylinder forming a printing base and co-operating with a flat reciprocating stencil and a wiper effective in the line of contact. Material from a supply roller 3 is passed round rods 4, 5, 6 carried on a framework 28, 29, around a cylinder 2 rotatable on a shaft 1, under a rod 8 and round rollers 11, 15, carried on a linkage 13, 12, through a drying chamber 31 and to a roller 16. A spring presses the material against the cylinder adjacent the bar 6. Two side discs, one adjacent each end of the cylinder, are fast on the shaft 1, and the links 29 and rod 8 are connected thereto. The cylinder is coupled to the discs by a releasable member 30. Stencils in a raisable and lowerable magazine 26 are placed in a frame 19 reciprocable in guides 17 and connected by steel tapes to the side discs. In operation, the frame 19 is moved to and fro as many times as there are colours to be printed, changing the stencil each time. This produces a 90-degree rotation of the cylinder and discs, and corresponding pivoting of link 28 about the rod 6, and link 13 about the roller axis 15, so that the material remains under constant tension and fixed relative to the cylinder surface. When the frame is retracted to the right, the newly printed material passes opposite a heating element 27 for intermediate drying by radiation or hot air. After an area of material is completely printed, the coupling member 30 is released, and the cylinder 2 and roller 16 rotated by a sprocket drive until the coupling member engages a recess in the cylinder which is stopped in position for the next repeat, member 30 also raising the rod 6 to allow this movement. A stationary wiper 25 designed with two blades at an angle to contain the printing colour, turns slightly about its longitudinal axis on each stroke, so that each blade in turn forces the colour through the stencil.

Abstract: 1508422 Measuring phase difference TORQUEMETERS Ltd 23 May 1975 [29 May 1974] 23743/74 Heading G1U [Also in Division H3] A device for measuring the phase difference between two signals includes respective threshold trigger devices receiving a different one of the signals, a bi-stable operated by the trigger device outputs to provide a pulse train whose mark/space ratio is proportional to the phase difference, means for measuring the ratio, means for selectively alternating the inputs to the trigger devices, means for interchanging the inputs and means for varying the trigger device threshold levels. For measuring the torque transmitted by a shaft 1, 3, Fig. 1, two toothed wheels 4, 5, mounted on a torsionally resilient section 2 thereof, co-operate with two magnetic transducers 6, 7 to provide signals whose phase difference indicates the angle of twist of the section 2 which is proportional to the torque. To make the meter 10 insensitive to differences between signal shapes from the two transducers, the trigger devices (60, 62) Fig. 2 (not shown) determining the points on each waveform between which the measurement occurs have variable threshold levels. These may be adjusted by potentiometers (VR1, VR2) supplying offset voltages to comparators therein. By operating button SW34 Fig. 3 signal X is reduced by 50% and adjustment made to bring the phase difference reading back to its previous value. A similar procedure is followed for input Y. A changeover switch is also provided to interchange X and Y and further adjustment made to achieve a true complement reading of the previous measurement. The measurement of the mark/space ratio is made digitally (see Division H3-H5).
