Title: Printing machines
IPC: B41L45/02
Filed: 1965-03-17
Abstract: 1,106,080. Printing-apparatus. ADDRESSOGRAPH MULTIGRAPH CORPORATION. 17 March, 1965 [1 July, 1964], No. 11332/65. Heading B6C. A cylinder machine suitable for printing on carbon paper-interleaved form sets F, Fig. 7, of varying thickness comprises a bed 10 adapted to support an embossed plate such as 16, an impression roller 32 supported in a carriage 12 arranged to be moved into the dotted line position and back again, means for lowering the roller in response to the initial movement of the carriage, and means for sensing a function of the combined thickness of the plate 16 and the set F, whereby the action of the lowering means is terminated when the roller 32 reaches a level at which it will apply a suitable impression pressure to the superimposed assembly on reciprocation of the carriage. A plurality of embossed plates and a date stamp may be supported on the bed, Fig. 1 (not shown), which is also provided with guides for the form sets. The shaft 33 of the roller 32 is supported in the eccentric bores of a sensing assembly 34 and a return cartridge 36, Fig. 2. The assembly 34 includes, in addition to its eccentric bore, a yield spring mounted in a concentric passage, a driving collar 84, a gear sector 86 adapted to engage a rack secured to the bed, and a clutch unit, Figs. 3 and 4 (not shown), provided with a housing 88 having a shaped internal surface engaged by rollers. The clutch unit acts to prevent the roller 32 rotating in a non-printing direction. In operation the carriage 12 is moved to the right, Fig. 7, and camming surfaces 60 are moved out of engagement with rollers 58 enabling a clamp 30 to be lowered on to a form set F by spring pressure. As the carriage is moved further the gear 86 engages its rack and rotates the roller which is lowered by means of its eccentric mounting; a spring in a concentric bore of the return cartridge 36 is simultaneously wound up. When the roller contacts the upper surface 31 of the clamp the lowering motion is stopped, further drive to the gear 86 being absorbed by the yield spring within the assembly 34. The clutch unit holds the roller in its adjusted position until it is released by either a projection on the bed at the end of the printing stroke or by an emergency release button 170. Means are provided, Fig. 10 (not shown), to prevent accidental leftward movement of the carriage. Plates and clamps of different thicknesses may be used. In the embodiment of Fig. 12 (not shown), the roller is lowered in two stages, the final lowering movement being effected after the roller leaves the clamp. A spacer is located under the leading edge of the plate. In a further embodiment, Fig. 13 (not shown), the clamp is replaced by a block or pad underlying the leading margin of the form set F.

Filed: 1949-04-30
Abstract: 661,995. Valve amplifying circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 17, 1950 [April 30, 1949], No. 11552/49. Class 40 (vi). In a wide-band direct-coupled amplifier the interstage coupling comprises a resistance potential divider to which the signal voltage developed in the load resistance of the first valve is applied and which applies a fraction of this voltage to the control grid of the valve in the succeeding stage, a capacitor connected to the control grid applies an equal voltage from an intermediate tapping point on the load resistor which is itself capacity loaded so that the time constants of its parts on either side of the intermediate tapping point are substantially equal. Fig. 1 shows a D.C. connected intervalve coupling in which the total voltage developed across the load resistors Ra and Rb is applied to a resistance potentiometer R1, R2, a tapping on which is directly connected to the control grid of valve V2 which is also connected to the junction of resistors Ra, Rb via capacitor C, the value of which is large compared with the input capacity C2 of valve V2. An additional capacitor Cb is connected in parallel with resistor Ra or across resistor R1 of such a value that the time constants Ra.Cb and Rb.C2 are equal. The resistors are selected so that R1/R2=Ra/Rb. In a modification, Fig. 2 (not shown), the load resistors of the first stage are located in the cathode circuit of the valve so that the first stage operates as a cathode follower.

Abstract: 864,690. Liquid expansion thermometers. REGULA-VYUOJ NARODNI PODNIK. April 11, 1958 [Sept. 24, 1957], No. 11587/58. Class 97(3) [Also in Group XIII] A liquid expansion thermometer comprises a first bellows 14 and a second bellows 13 both fixed at one end to a common supporting plate 18, the plate itself being supported by a linkage frame 24, 19 hinged to a housing; attached to the other ends o the respective bellows are one end of respective rods 21, 25, the other ends of the said rods being secured respectively to the housing, and to temperature-indicating means 22 such as a pointer. Springs 20 act to restore the bellows after compression. The bellows are contained in separate casings 12 holding a suitable liquid. The liquid in one casing is connected by a capillary tube 15 to a member 17 which acts as the temperature-detecting member. The other casing is connected to a similar capillary tube 16, which may be connected to a further temperature-detecting member if temperature differences are to be measured. With the arrangement shown, bellows 14 acts as a compensating device. Change in the general ambient temperature of the bellows (but not affecting the detector 17) causes both bellows to be deformed to the same extent; since rod 21 is fixed to a fixed base, the whole plate 18 is displaced, so that point 22 remains stationary. Fig. 1 (not shown) represents a simpler known arrangement, in which the liquid is inside the bellows instead of outside.

Title: Improvements in or relating to electric pulse signalling systems
IPC: H04J3/12
Filed: 1945-05-12
Abstract: 596,676. Multiplex pulse signalling. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA, P. K., and AMBROSE, D. M. May 12, 1945, No. 11987. [Class 40 (v)] Calling, dialling, supervisory &c. signals are transmitted in a pulse communication system by time modulating the pulses with a periodic wave having a frequency related to the pulse recurrence frequency by a ratio expressible by small integers and of phase related in definite manner to that of the pulse train. As described, a multichannel transmitter, Fig. 1, comprises a master saw-tooth generator 1, with a repetition frequency of 10,000 c.p.s., which is connected to four channel pulse generators and pulse-phase modulators 2 ... 5 and a synchronizing pulse generator 6. The pulse outputs are mixed, amplified and shaped in unit 7 and applied to the communication medium 8. Modulating signals such as speech are applied from terminals 9... 12 through switches 13 ... 16 respectively to the modulators 2 ... 5 respectively which may be of the type described in Specification 596,658. The master generator 1 is also connected to a frequency divider 17 with an output of 5000 c.p.s. which is passed through low-pass filter 18, the sine wave output of which is fed through a phasing network 19 to the lower contacts of switches 13 ... 16. Operation of these switches to their lower contacts for calling purposes disconnects the corresponding signal source 9, 10, 11 or 12 and substitutes the 5000 c.p.s. sine wave from unit 19. At the receiver, Fig. 2 (not shown), a low-pass filter following the demodulator rejects the calling frequency and passes the speech while a band-pass filter and a tuned detector operate a relay and bell or other signal when the calling frequency is received. Alternatively and preferably the calling frequency wave is of rectangular form and its requirements as to frequency and phase are discussed in the Specification. In some systems it is preferred to provide individual phasing networks such as 19 for each channel.

Title: Improvements in liquid level indicators
IPC: G01F23/00
Filed: 1956-04-24
Abstract: 812,978. Indicating liquid levels. CANDY FILTER CO. Ltd., and THOMAS, W. D. J. April 8, 1957 [April 24, 1956], No. 12520/56. Class 123(1) In a liquid level indicator a displacer body (not shown) is suspended within the liquid by means of a coupling 8 on a rod 7 attached to a spring 5 the upper end coils 5a of which are clamped by a ring 6 to the concentric boss 4 of a platform 3 bridging a casing 1 arranged for bolting through a flange 2 thereon to the top of a liquid container (not shown), the displacer body being thus suspended in the liquid through an opening in the top of the container. A cross-bar 17 is arranged to span the spring 5 intermediate the length thereof so that the opposite ends of the bar, which are offset by half the pitch of the spring, project through the spring coils, the cross-bar being detachably secured by a nut 19b to the lower end of a stud 19 which is screwed into a collar 18 rotatably located within the boss 4. The screw threads on the stud 19 and the collar 18 have the same pitch as the spring coils when unloaded so that rotation of the stud 19 when the collar 18 is stationary serves to rotate the cross-bar and axially to displace the bar lengthwise of the spring locating thereby more or less coils above the bar thus altering the effective length of the spring. To ensure that the coils above the cross-bar 17 have no effect the collar 18 is rotated and the stud 19 held stationary thus axially displacing the latter and compressing the coils. The rod 7 is attached to a counterweight (not shown) by means of a nylon cord 9 which extends through the spring 5 and the stud 19 over a pulley 10 and down to the counterweight disposed in the casing 1, the pulley 10 thus rotates by an amount corresponding to the axial movement of the displacer body and it may be attached to a pointer for indicating this movement or to a transmitter 13 forming part of a remote indicating system. The pulley 10 and the transmitter 13 when it is employed, are enclosed by a dome-like casing 14 which may be provided with an indicator dial 15 actuated by a receiver 16 or the dial and the receiver may be remotely positioned from the indicator.

Title: Device for drilling non circular holes
IPC: B23Q35/10
Filed: 1933-05-01
Abstract: 418,680. Drilling non-circular holes. MASON, W. H., 59, Kenwood Road, Stretford, Manchester. May 1, 1933, No. 12574. [Class 83 (iii).] A device for drilling non-circular holes has a rotating bit and a cutter mounted on a slide which reacts to a cam through an adjustably pivoted lever. The cutter B, supported against a backing bit A, is carried by a slide C, reciprocated against spring pressure by the lower end of a pivoted arm E. This arm is pivoted on an adjustable plate H, movements of which are guided by a cam-projection J, the plate being fixed in its adjusted position by a wing-nut K. The upper end of the arm E is oscillated by a cam-piece F shaped correspondingly to the hole to be cut and held stationary during rotation of the other parts of the device. Adjustment of the plate H alters the effective movement of the arm E with respect to the cutter-slide and thus allows differently-sized holes to be cut with the same cam.
