Title: Improvements in and relating to platen printing presses
IPC: B41F1/26
Filed: 1923-05-09
Abstract: 219,917. Haddan, R., (American Type Founders Co.). May 9, 1923. Platen machines.-A platen printing-machine which is readily conveytible for printing with automatic or hand feed as described in Specification 219,758, is fitted with an oscillating arm carrying a suction sliest-separator which can be swung aside when the pile table and sheet-transfer mechanism are moved out of acticn to permit of hand-feed. The suction separator 53, Fig. 1, is moved to and from the sheet pile 52 by an oscillating arm 56 the pivot 60 of which is carried by a support 59 on an oscillating U-shaped bracket 57 mounted on the frame of the machine, and operated by a crank and connecting-rod 10. The arm 56 is moved horizontally by the support 59 and is moved vertically by means of a roller 78 resting on a fixed triangular cam-plate which extends towards the platen. The suction nozzle 53 is mounted to slide in a holder 62 adjustably secured to a rod 54 in the arm 56, and its downward movement in the holder is limited by a screw 65. The nozzle 53 is constructed as shown in Figs. 3 and 4, and when it first contacts with the pile is in the position shown in Fig. 4. The arm 56 then descends further, and the nozzle 53 moves about a pivot 70 mounted in ears 57 in a foot 66 of the nozzle bracket 64 so that its straight portion 75 then engages the top sheet, and a vacuum is then formed and the sheet is drawn towards slits 77 on opposite sides of a shoulder 76 of the nozzle. The sheet is thus given a sliding movement away from its leading edge, and is also buckled or crimped against the shoulder 76, thereby ensuring good separation. For dealing with thick paper the shoulder 76 is dispensed with, and the rear part of the nozzle is inclined. The pivotal motion of the nozzle 53 is controlled by stops 68, 72. When the machine is used for handfeed the arm 56 is moved to the position shown in dotted lines in Fig. 1 by rotating the support 59 which is fitted with a stop 61 acting on a corresponding stop on the arm 56.

Filed: 1945-06-25
Abstract: 594,441. Rotary compressors. HICKS, T. L. June 25, 1945, No. 16164. [Class 110 (ii)] A compressor of the outwardly-sliding vane type is provided with a pivotable seal 40, under liquid pressure, the liquid also being supplied beneath the vanes to force them outwards. The liquid is under pressure from the compressor delivery. The vanes 14 are built up of interlocking segments, the lateral segments being forced against the side-walls of the working chamber under liquid pressure. The compressor parts may be of light metal or plastic material with the seal 40 of material which quickly responds to temperature changes. The compressor delivery port 24 leads into a chamber 18 causing oil to be forced up a pipe 43 leading to a space 41 behind a bar 42 which is thus forced downwards to cause the seal 40 to press against the periphery of the rotor 11. Various sizes of bar 42 may be inserted to vary the pressure area on the rotor. Oil is also forced up a pipe 25, past a non-return valve 28 and feeds a groove 15 and thus the bases of the vane slots. The groove may extend for less than a complete circle, being discontinued near the delivery port. The vanes are provided with oil grooves 57 in their surfaces. In a modified arrangement, oil is led from the reservoir through radial and longitudinal passages in the rotor shaft. The seal may pivot about its centre and pressure oil supplied to one side of the centre, dependent on the direction of motion of the rotor.

Title: Improvements in or relating to electrical impedance networks
IPC: H03H7/18
Filed: 1936-06-15
Abstract: 476,811. Impedance networks. SIEMENS & HALSKE AKT.-GES. June 15, 1936, No. 16662. Convention date, June 14, 1935. [Classes 40 (iii) and 40 (v)] A phase-shifting quadripole, of lattice or bridged-T type, particularly for modifying a modulated carrier wave for single-side-band transmission, is so designed that it has an invariable image impedance and, over a certain frequency-range, an invariable attenuation constant and an invariable phase constant, the latter being preferably equal to Œ¢#. For this purpose a lattice section having inverse arms with impedances R1, Z<2>/R1, Fig. 1 (not shown), is employed, the image impedance Z being consequently real and invariable. The impedance R1 is represented in the complex plane in Fig. 3. When the attenuation constant of the quadripole is invariable, the point representing R1 at various frequencies traces out one of a family of circles having their centres on the real axis. The circle representing R1 for a particular value of the attenuation constant is shown at B. When the phase constant of the quadripole is invariable, R1 is represented by a similar family of circles having their centres on the imaginary axis and passing through the two points (ŒZ, O). The circle for a constant phase-shift of Œ¢# has its centre at the origin and is indicated at A, Fig. 3. The required value of R1 corresponds to a point of intersection of the two circles, and the Specification shows how to construct R1 so that its complex value may remain approximately stationary in the neighbourhood of this point over a range of frequency. R1 may have the form shown in Fig. 4, where Z is a resistance equal to the desired image impedance while l, L are inductances, l being substantially smaller than L. The form of the other branch of the network is inverse to that of R1.
