Title: Improvements in rubber covered bar expanders used in cloth expanding machines
IPC: D06C3/06
Filed: 1922-01-31
Abstract: 194,091. Taylor, T., Winstanley, J. H., and Rooney, J. H. Jan. 31, 1922. Feeding webs.-In cloth-expanders of the kind comprising a number of bobbins mounted on a curved bar and covered with a rubber sleeve, the sleeve is formed with an internal flange by which it is secured to the end bobbin so that the full length of the sleeve may cut upon the cloth. The invention is particularly for use with expanders for double width cloths, in which two expander bars arranged end to end are employed, and the inner ends only of the sleeves may be secured in the usual manner. The sleeve a is formed with a flange c and a recess b and is secured to the end bobbin e or to an intermediate washer by screws g and a wacher f mounted in the recess b. A bead c<1> formed on the flange c engages a groove formed in the bobbin. If both ends of the sleeve are so scoured, the flanges are slit radially to allow them to be forced over the bobbins. The bore of the sleeve is of octagonal section.

Title: Indication of the passing of a gunnery projectile through an area in space
IPC: F41J5/02
Filed: 1972-01-20
Abstract: 1379078 Target practice aid AUSTRALASIAN TRAINING AIDS PTY Ltd 20 Jan 1972 [21 Jan 1971] 2878/72 Heading H4D [Also in Division F3] In air to air target practice the firer of the missile is given an indication as to whether the missile has passed through the target area by means of detecting reflections from the missile of a beam of light irradiating the target area or an area in front of the target. The beam of light can be stationary (Fig. 1), with a fan shape wide enough to fill the area, or it may be narrow and be scanned through the area (Fig. 2). In the system of Fig. 1, Helium/Neon laser 1 transmits 95-99% of its beam through a semi-reflecting quartz mirror 3 to a perspex light guide 5, Fig. 3, which broadens out the beam in to a flat fan 8. A reflection from a missile travels back through the light guide and is reflected by mirror 3 to a PIN diode 15 via interference rejecting filter 12. In the system of Fig. 2, the fan laser beam from light guide 5 is reflected off of a four sided rotating mirror drum 32 to give four scans of the area in front of the target, Fig. 6. Threshold detectors for the reflected signals determine upper and lower range limits for the swept area. A disc 36 rotating with the drum has a series of coded holes through which a diverted part of the laser beam passes to give coded pulses 54 defining the sweep angle of the beam. A three gate arrangement, Fig. 8 (not shown), with the gates sequentially enabled for successive thirds of the beam scan period enables the determination of "left of target", "hit" and "right of target". The thus analysed reflection signals are then stored for subsequent information transmission to the firer.

Title: Refill cartridge for ball point pens
IPC: B43K7/00
Filed: 1958-01-29
Abstract: 832,300. Reservoir pens. FISHER. P. C. Jan. 29, 1958, No. 2924/58. Class 146(3) A writing- unit for a ballpoint pen is constructed so that it can be used in the holders of most pens. As shown, the actual ink reservoir 5 is about two-thirds the full length of the unit, and the upper end has pressfitted therein a stud 20 having two planes of weakness 22, 23, that at 23 being the weaker. The upper end of the stud 20 is bored to receive a press-fitted pin 26 having a plane of weakness 27 which is weaker than that at 23 in the stud 20. An extension tube 30 fits over the pin 26, and is provided with two planes of weakness 31, 32, the latter being the weaker. An external sleeve 40 surrounds the upper end of the reservoir 5 and most of the upper structure. The reservoir 5 is provided with stops at 8, 9 e.g. by squeezing the reservoir to deform it, and a spiral spring 35 is arranged between the stop 8 and the writing point 15. For use in a particular pen, the writing unit is broken at one of the planes of weakness 22, 23, 27, 31, or 32 to reduce it to the approximate length of the spent writing unit. The slidable outer sleeve 40 is used for this purpose by slidit along the unit until the inner end is opposite the appropriate weak plane, whereupon the sleeve is given a slight lateral movement to snap off the excess length of the unit. The outer sleeve 40 may be retained on the unit in some cases to serve as an adaptor or shim. The compression spring 35 is provided for use in certain types of pen, but it is readily removable where it is not required. Since the planes of weakness in the unit are progressively weaker in the upward direction, it is unlikely that the unit will be severed at a lower point during the severing process.

[Also in Groups XVI and XIX] Data sensed from record cards is checked in the circuit of Fig. 1 to ensure that the correct number of digits are present. The code used has one group of six bit positions for numerals 0-9 and an extra group of three positions for alphabetic characters. Two positions in each group should be marked. The card index positions are sensed successively by photocell 1 and the signals arriving serially at gate 3 are stored in appropriate ones of valves 6A-6F and 6X-6Z under the control of a multicathode tube 4. As each digit arrives in each store it is counted by a scale of four counter 7 or 8, consisting of a pair of triggers. Valid signals have two digits in each group and the corresponding outputs of the counters are connected to a gate 9. The last cathode of tube 4 causes the gate 9 to pass a signal to gate out the contents of the stores. For numerals, the switch 21 is put in the uppermost position to connect the zero output of counter 8 to the gate 9. In mixed characters the lowermost contact of switch 21 is used. This disconnects the X, Y, Z group circuit altogether so that no check is made on this part of the signal. The output may pass to a sorting machine (see Group XIX) or a printing machine (see Group XVI).
