Abstract: 740,285. Writing machines. POWERSSAMAS ACCOUNTING MACHINES, Ltd. Aug. 3, 1954 [Aug. 4, 1953], No. 21539/53. Class 146(3) An apparatus for producing hectographic copies of characters comprises a platen, means to feed impression-receiving material over the platen, reciprocable styluses normally spaced from the platen and supported for movement relative to the platen, means to feed transfer media between the styluses and material, and means to move the styluses relative to the platen to define, by dots and dashes, on the side of the material facing the transfer media characters which read in reverse from right to left of the material. The marking ends, 3, Figs. 2A and 3, of a plurality of styluses, each consisting of a flexible wire 1 slidable in an outer member 2, pass through apertures 11 in a reciprocable guide member 10. The guide member 10 is slidable in guides 12, 13, and is connected to a connecting rod 14 attached to an eccentric 15 driven by a shaft 16. The shaft 16 also drives a plurality of contact carrying discs 19, Fig. 4 (not shown), which effect the energization of solenoids 6. The solenoids 6 cause the wires 1 to be reciprocated towards a platen 7 in the manner described in Specification 707,736 to produce characters on material 8. The eccentric 15, Fig. 8, comprises a disc 15a coaxial with the shaft 16, a block 15c, having. a pin 15d, being adjustable along a slot 15b of the disc by screws 15e, 15f, such that the centre line 15g of the pin 15d may be adjusted in relation to the axis 16a of the shaft 16. Thus, the eccentric 15 may be adjusted, such that the eccentric is 180 degrees out of phase with the rotation of the contact carrying discs, such that mirror images of characters are produced by the styluses on the material 8 fed between the platen 7 and transfer media 9, Fig. 3, such as carbon paper. The eccentric 15 may also be adjusted to vary the maximum widths of the characters by reducing its throw. Specification 738,100 also is referred to.

Title: Improvements in or relating to method of embossing gelatine capsules
IPC: A61J3/00
Filed: 1952-09-01
Abstract: 717,888. Embossing gelatine capsules. SCHERER CORPORATION, R. P. Sept. 1, 1952 [May 3, 1952], No. 21935/52. Class 100 (2). A method of embossing a figure in relief on the surface of a gelatine capsule 10 comprises applying clamping jaws 16, Fig. 3, to the first and third quadrants of the capsule to effect a bulging of the other two side quadrants, supporting one of the bulged sides and simultaneously applying, with pressure, a heated die 18. In the form shown dies are applied on each side. The die face, Fig. 6, has a surface presenting a series of teeth 24 for contacting the capsule surface to be heated, the teeth being formed by a series of grooves 20, 22. The toothed surface, having a large surface area, causes rapid softening of the surface of the gelatine which then takes the shape of the surface and reduces the effective surface of the die. Thus, it is stated, the heat applied renders only a surface layer of the capsule area plastic. The figures 26 are formed by recessed portions which do not contact the surface of the gelatine and consequently the corresponding areas of the capsule surface do not become plastic. The die temperature is between 100‹ F. and 300‹ F. and it is applied for 0.01 to 0.5 seconds. Specification 395,546, [Group VI], is referred to.

Filed: 1944-11-09
Abstract: 583,631. Pulse generating circuits. JELONEK, Z., DALZIEL, R., and SMITH, R. A. GUNN-. Nov. 9, 1944, No. 22124 [Class 40 (v)] A circuit for generating short pulses at a stable frequency comprises a multi-electrode valve having its first control and another electrode arranged in an oscillatory circuit, with biassing means to limit conduction to the peaks of oscillation only and with means for feeding a slightly delayed negative impulse to the second control grid to produce an asymmetric pulse. The Figure shows a heptode valve V1 with cathode, first and second grids connected as triode oscillator tuned by parallel connected inductance L1 and capacity C1 in second grid lead ; a piezo-electric crystal X1 is inserted in conventional manner. The first grid, connected to the cathode through leak resistance R2, draws current during positive peaks of oscillatory voltage, developing selfbias so as to cut off space current except during the said positive peaks. When space current flows, the voltage developed across resistance R1 is applied as a negative pulse through condenser C2 to a second control grid ; condenser C3, or, alternatively, another condenser (not shown) in parallel with resistance R3 produces a slight delay so that the anode current which commences to flow is cut off almost immediately by the negative pulse on the second control grid producing a short asymmetric pulse rich in harmonics in the anode load, which may be tunable to a particular harmonic.

As shown, Fig. 1, an accumulator has its lowest order pinions 20 provided with ten teeth 20a and five carry. teeth 20b for binary operation, whilst all the other accumulator pinions 2 have one carry tooth for decimal operation. Each decimal actuator 3 has a lug 3a adapted to engage the corresponding set pin in a carriage 6 and is arranged to enter into the add or subtract side of the accumulator through printing sector 14 and further sector 10. When the carriage is in its home position, Fig. 1, carriage end plate 6a acts on a lug 27c of a slide 27 to keep a lug 27b clear of a recesses 21b, Fig. 2, formed in the binary actuator 21. This actuator, as well as all the decimal actuators are then free to move for totalling purposes. After setting one or more digits and thus indexing the pin carriage, slide 27 is moved by spring 28 to position lug 27b in recess 21b to block the binary actuator. Subsequent depression of key 32 acts through slidable wedge 29, Fig. 6, to move slide 27 against spring 28 to unblock actuator 21. Wedge 29 is locked in its depressed position by the end of slide 27 engaging in groove 29a and is only freed when the pin carriage is returned to home. Blocking mechanism 34 (also Figs. 7 and 9, not shown) is provided to prevent depression of key 32 when the pin carriage is in home position.

Abstract: 1475068 Pressure transducer LUCAS INDUSTRIES Ltd 31 July 1974 [10 May 1973] 22305/73 Heading G1N [Also in Divisions F2 and H1] A pressure-responsive transducer has a housing 10 with an inlet 11 for connection to a fluid pressure source which pressure acts to urge member 12 inwardly against resilience of bellows 14 thereby producing axial movement of stem 16 and of an annular portion 17 of the member coaxial with the stem. The annular portion has circumferential slots 18 within which balls 19 are movable. The other end of the bellows is secured to an element 15 rigidly mounted to the housing. A further element 20 has an axial bore in which the stem 16 is slidable,and is restrained against rotation in the housing. Elements 15, 20 have respective helical grooves 21, 22 engaged by the balls 19 and having a helix angle of 60 degrees and 30 degrees respectively. In use a rise in pressure at the inlet urges member 12 against the bellows and since element 15 is restrained against movement, axial movement of the member 12 causes the bells 19 to move around the slots thereby producing axial movement of the further element 20. Since the lead of a 30 degree helix angle is three times that of a 60 degrees angle, the element 20 moves three times the distance moved by member 12. The end of element 20 remote from the inlet engages a stem 23 to operate a switch 24 to provide an electrical output signal.
