Title: Improvements in and relating to hand-operated platen printing presses
Inventor: FARR SYDNEY GEORGE
IPC: B41F1/00
Filed: 1948-07-20
Abstract: 649,744. Platen printing-presses. FARR, S. G. July 20, 1948. No. 19436. [Class 100 (ii)] A hand-operated platen printing-press comprises a type-bed 1 to which the platen 2 is pivoted, the pivot means consisting of a transverse pin 3 in brackets 4 on the bed, blocks 5 pivoting on the pin at each end and having screw-threaded stems 6 which pass through bores in lateral lugs 2b in the platen, and are provided with wing-nuts 7, and springs 8 interposed between the blocks 5 and the platen. The platen 2 can thus be adjusted relatively to the bed 1, and the pivotal connections are clear of the usual gripper fingers mounted on the pin 3. The free end of the platen is adjustable relatively to the bed by a pair of brackets 11 on the platen, each carrying an adjustable stud &c. 12. Pressure is applied to the platen 2 by a handle 9 pivoted thereto and provided with a nose portion adapted to engage under a yoke &c. 10 secured to the bed. Inking-apparatus.-An extension 13 secured to the bed 1 is recessed to receive a circular ink-distributing disc 14 which is retained by a screw-and-nut 15, 16, and a spring 17 between the nut and extension 13. An inking-roller 18 carried in a channel-shaped strip 19 and provided with end guiding flanges 21, is adapted to be moved over the disc 14 and then over the type, when the platen is lifted, by means of a flexible link 20 connected to the platen and to one end of the roller. The roller is pulled slightly askew by the link 20 during its travel, and this, combined with the drag of the viscous ink on the disc 14, gives a small unidirectional rotation of the disc to ensure a more even distribution of the ink. Side guides 1a on the bed 1 constitute bearers for the inking-roller.

Title: Information store
IPC: H03K17/62
Filed: 1965-05-10
Abstract: 1,086,473. Read-only stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 10, 1965 [June 17, 1964], No. 19555/65. Heading G4A. An information store comprises a plurality of memory locations selectively addressable by means which when addressing a memory location varies the potentials of two input terminals, e.g. 82, 94 thereof in opposite senses, causing a transformer, e.g. 96, coupling said terminals to the location to apply a balanced drive to the location. In Fig. 1, a matrix is used to select and drive a particular word line 12, 13 . . . 20 of a readonly store. Sense wires 22 . . . 30 are provided. At each row-column intersection, the row wire is connected to the column wire by a series combination of a first lead 99 of a transmission line transformer 96, two equal resistors 106, 102, a second lead 98 of the transformer 96 and a diode 40. The resistors junction is earthed 71. The word line is connected between the two lead-resistor junctions 103, 107, and is thus given a balanced drive to reduce noise. The transformer 96 may consist of the two leads 98, 99 twisted together around a ferrite core, the core presenting a large impedance to reflected or common mode voltage components from the word side. Alternatively, the ferromagnetic material may surround the leads, or a block of it surround the leads of more than one transformer, or a parallel strip line or coaxial cable may be used. The transformers act as isolating inductors for non-selected word lines. A modification (Fig. 4, not shown) suitable for lower frequencies uses a pulse transformer, the primary of which is connected in series with a diode between the row and column wires of the matrix. The ends of the secondary are connected to respective ends of the word line with two series-connected resistors connected across the latter. The junction between the resistors and the secondary centre point are earthed.

Abstract: 417,808. Pneumatic despatch apparatus. KRIEGER, L., 7, Avenue de la Mesange, Le Parc St. Maur, Seine, France. July 10, 1933, No. 19558. [Class 116.] In a pneumatic despatch or other conveyer system in which reflecting surfaces on the carrier or object co-operate with a light-source and a photo-electric cell to control the switching operation by which the carrier or object is delivered at a station or diverted from the main conveyer path, the desired station or switching point is selectively determined by mounting the reflecting surfaces at appropriate inclinations relative to the axis of the carrier or object. A switching or delivery operation is effected when, as shown in Fig. 1, the mirror m on the carrier b is mounted at an angle such that the lightbeam g from the source i passing through an opening in the tube a is reflected through an associated window g<1> on to the photoelectric cell before the carrier reaches the switching point. The cell current is applied to amplifiers and relays k operating a solenoid f which moves a switch arm e to the position to divert the carrier into the branch or delivery tube a<1> in which the circuit of the magnet f is opened by the passage of the carrier, as described in Specification 403,386. The reflecting surfaces may be arranged at the front and/or rear of the carrier and may produce a double reflection of the light beam, Fig. 4, (not shown). Specification 391,317 also is referred to.

Title: Storage system for palletized goods
IPC: B65G57/03
Filed: 1978-05-15
Abstract: The storage apparatus for palletised goods has a number of storage lines, it being possible for pallets (5) loaded on each storage line to be arranged one behind the other. The storage apparatus is designed in such a way that it is distinguished by low construction cost, easy and accurate controllability and execution of the transport movement in one or both directions, protection of the storage material, high operating reliability, small space requirement and low wear. For this purpose, at least two multi-piece supporting surfaces (3, 4, 6) for the pallets (5) run along the line. Each supporting surface can support the pallets of this line by itself. One (3, 4) of the supporting surfaces is attached in a fixed position, and the other supporting surface, which in the state of rest runs below the level of the fixed supporting surface (3, 4), can be raised above the fixed supporting surface (3, 4) for transporting the pallets (5) along the line and can be moved in the raised state in the line direction for transporting the pallet by little more than a pallet length (measured in the line direction). It can then be lowered again and returned into the initial position. <IMAGE>

Title: Improvements in or relating to filters
IPC: B01D35/12
Filed: 1937-07-19
Abstract: 494,854. Filters. FILTRATION & WATER SOFTENING PROPRIETARY, Ltd. July 19, 1937, No. 19958. Convention date, July 23, 1936. [Class 46] In cleaning a filter bed by upward flow of water therethrough while water is also directed under high pressure upon the sur. face of the bed, the upward flow being continued after the flow of surface wash water has been stopped, the valves are operated so as to secure a constant flow of surface wash water and a constant rate of discharge of the combined surface and upward flow wash water. The Figures show an arrangement comprising twelve filter chambers in two groups 10, 11, of six with a common supply pipe 15, a common filtrate discharge pipe 21 with valve 22 and a common wash water discharge pipe 32 with valve 33. The flow of water to be filtered to the chambers of each group is controlled by a valve arrangement as described in Specification 346,376 comprising a chamber 23 to which water from the pipe 15 passes through a branch 16 and from which it is delivered to the several chambers through ports 25 and pipes 18. When it is desired to cleanse one of the filter chambers, the valve 22 is closed and the spindle 27 of a valve member 26 is rotated manually or by an electric motor 35 through gearing so that the member 26 cuts off communication of the corresponding pipe 18 with the chamber 23 and opens it to a waste pipe 31. Filtered water from the remaining chambers then passes upward through the chamber so cut off. At the same time, jets of water are directed on to the surface of the bed from rotary distributing pipes 49 to which water is supplied through a pipe 48 from a valve device with chamber 39 and ports 40 normally closed by a valve member 41 on a spindle 37 coupled to the spindle 27. Rotation of the spindle 37 brings an aperture in the valve member 41 over the port 40 corresponding to the filter chamber which is being washed. The arrangement is such that as the spindles rotate together the filter chambers of each group are successively cleansed and that for each chamber the reverse flow of water and the flow of surface wash water start simultaneously, while the flow of surface wash water terminates before the reverse flow. The spindles 27, 37 may be coupled together in such manner as to permit adjustment of the phase relationship of the valves. The surface wash water may be under pressure of a centrifugal pump 47 and under control of a valve 45. The pipes 49 rotate on the Barker's Mill principle, and means, for example, a friction device 53, may be provided for ensuring that the rotation is such that the jets of water have a sufficiently high velocity. Each pipe 49 may be provided with two sets of nozzles 50, 51, Fig. 8.
