Patent GB-106603-A (GB)
IPC: B41B5/06
Abstract: 106,603. Barr, M., and Maw, T. F. May 18, 1916. Moulds and matrices f o r type-casting machines.-A mould for casting justified lines of type comprises relatively adjustable blades 116, 117 for forming the leading and following faces of the type respectively, the blade 117 being formed in two parts 117, 117<a> which can be adjusted relatively to set the mould for casting spaces integral with the type. The blades 117, 117<a> may be adjusted by means of a wedge 134, which is set by means of the mechanism described in Specification 106,517. All the type, except the first in each line, may, as described in Specification 106,602, be cast on the leading side in contact with the preceding type, there being no fusion of this type. The formative cavity 101, Fig. 9, of each character-matrix 95 is formed on the leading side with a narrow wall, and on the following side with a shoulder 102, which forms an abutment for the blade 117<a> and is at the same distance from the cavity for all matrices. Blank matrices are provided for casting ordinary and high or low quads. For casting high quads, a higher blade 117 and a shallower blade 117<a> are substituted for those shown. The matrices may be presented to the mould by the mechanism described in.Specification 106,517. The blades 117, 117<a> are secured to slides 132, 133. The blade 116 is provided with a block secured to bars 129 provided at the righthand end with a stop 130 adapted to engage a stop 131 on the slide 132. Initially, a stop on the block engages a fixed stop 128, and the blades 117, 117<a> are flush and in contact with the blade 116, the distance between the stops 130, 131 being then equal to the lock-up length of the line. The slides 132, 133 are reciprocated by means of levers, the slide 133 engaging its lever through a spring member, which yields when the blade 117<a> engages the matrix. Before the last type of a line is cast, the wedge is withdrawn, and the slide 132 and blade 117 are moved as far as is permitted by the stop 130, so that the last type cast will fill out the line exactly. The upper part, formed by the blade 117<a>, is above chase height and may be slightly greater or less than the lock-up length.

Title: Improvements in or relating to aerial feed and aerial tuning circuit arrangements
IPC: H03H7/38
Filed: 1937-04-15
Abstract: 493,860. Impedance networks; wireless receiving and multiplex systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., RUST, N. M., and RAMSAY, J. F. April 15, 1937, No. 10773. [Classes 40 (iii) and 40 (v)] An impedancematching network for connecting an aerial AE or a receiver to a feeder 2 is tapered or composed of asymmetrical sections whose image impedances at a required frequency form a progression while their image transfer constants are equal throughout. Two aerials for alternative use may be permanently so connected to the same feeder. Impedance-matching networks. A balanced aerial AE, Fig. 1, may be coupled to the unbalanced feeder 2 through a network 41 which is balanced at the aerial end and unbalanced at the feeder end, while the inductances and condensers change in magnitude progressively, as shown, so that the impedance is matched at each end. Instead of the lowpass network shown in Fig. 1, a high-pass network may connect a frame aerial to the feeder, Fig. 2 (not shown), or a band-pass network may be used, Fig. 4 (not shown); and the sections may be of the L instead of the H type, Fig. 3 and Fig. 4 (not shown), or of lattice, bridged-T or other type. The Specification gives the theory of tapered matching. The ratio B of input image impedance to output image impedance is the same for each section, but the output impedance for one section is equal to the input impedance for the next section. The image transfer constant is the same for all sections. Then B varies with frequency, but the matching is exact for a selected frequency, such as the geometric mean frequency of the working range, and errors in matching at neighbouring frequencies are reduced by increasing the number of sections. The cut-off frequency of the network is arranged to be outside the working range. Tuning feeders for reception. The tuner T, Fig. 5, may be inserted in the middle of the feeder, Fig. 5, which is then matched to the aerial and receiver by networks 41, 41<1> respectively ; the tuner may be a simple resonant circuit in series with the core of the feeder, Fig. 6 (not shown), or a tee-section with series inductances and shunt tuning condenser, Fig. 7 (not shown), or it may comprise a pair of coupled inductances, Fig. 8, in series with unitarily controlled and symmetrically earthed condensers. A long-wave-stopper condenser of 1,000 ÁÁF. may be interposed. Multiplex wireless telegraphy. A medium- and-long-wave aerial AE is connected to a feeder 2 through a low-pass network 41 with tapered image impedance, and a short-wave aerial 7 is connected to the same feeder through a similar but high-pass network 42. The aerials are for alternative use, but both are permanently connected to the feeder. The networks 41, 42 are tapered, the inductances and condensers changing progressively in magnitude from one end to the other, as shown, for the purpose of matching the impedances.

Title: Apparatus for testing and emplacing flexible packages
IPC: B65B5/06
Filed: 1974-03-12
Abstract: 1456918 Testing and cartoning sealed packages NEO-DYNE INDUSTRIES Inc 12 March 1974 [19 March 1973] 10943/74 Heading B8C [Also in Division G1] An apparatus for testing packages, having sealed-in gas, for leaks and for cartoning only satisfactory packages, comprises a testing device which compresses each package at a station 30, a paddle 34 for pushing each satisfactory package from a conveyer 24 on to an accumulator tray 36, and a transfer head 46 for lifting a predetermined number of accumulated packages and placing them in a case 70 supplied on a conveyer 53. The testing device comprises a platen which is lowered on to the package so that, in the case of a sound package, the resistive force caused by compression of the package, stops such lowering movement before the platen reaches a limit point. In the case of a package having a leak, the resistive force is insufficient to stop the platen before it reaches the limit point whereat a micro-switch is actuated. The packages are also tested at station 30 to determine whether they exceed a predetermined minimum weight (see Division G1). Rejected packages are conveyed past the paddle 34 to a discharge shoot 48. The transfer head 46 is movable vertically and horizontally. The downward movement of the head 46 to pick-up the accumulated packages is controlled so that the head 46 travels at a high initial speed and slows down just prior to picking up the packages by suction. The transfer head 46 is controlled to deposit rows of packages in layers and it may also be controlled to deposit rows of packages side by side. The conveyer 53 for the case 70 is halted when the case interrupts the beam of a photo-detector at the loading station. When the case has been loaded it is automatically lifted and guided over the photodetector beam and discharged by the conveyer. The operations of the various components of the apparatus are automatically controlled by a control logic which also receives signals relating to the results of the tests performed on the packages and controls the paddle 34 accordingly. The apparatus may be adjusted to alter the resistive force and minimum weight required of the packages.
