Abstract: 462,662. Knitting. LEEDHAM, L. H., HOLMES, H. H., and WILDT & CO., Ltd. Aug. 12, 1935, No. 22691. [Class 74 (ii)] A knitting-machine comprises the combination of patterning means for producing preferably tuck or float stitch unraised patterns in selected areas of the ground fabric and also means for patterning, e.g. by sinker-selection, other areas by producing therein a plush pile rising above one surface of the ground fabric. Two pattern drums 20, 21, which may be of the form disclosed in Specification 446,901, with tricks and co-operating bits 22, 23, act upon selector cams 26, 31, the cams 26 pivoting about a spindle 27 mounted in a ring 72. Cam followers 29, pivoting on a spindle 30 on a bracket 28, are moved by the butts on the bits 22 to operate the appropriate selector cams 26, but, by angular adjustment of the ring 72, it may be arranged that the noses of the cam followers 29 move info recesses 75 in the cams 26 and hence the latter are not operated. The selector cams 31 act directly upon the spacing jacks 37. The drum 20 is moved step-by-step by a spring-pressed pawl 63, actuated from the spindle 50, the drum 21 being similarly operated therefrom by a pawl 59. The spindle 50 is provided at its foot with a double rocker arm 66, actuated by a cam 67 rotating with the needle cylinder 32, so that it has a rocking motion. The needles are operated selectively by the raising cam 40, through the spring jacks 37 which are pressed at 48, as described in Specification 461,083, and through jacks 35. The sinkers 43 are operated selectively through the patterning mechanism above set forth and sliders 42. The cam 67 is arranged so that a change-over in pattern produced by needles and sinkers will occur in the same vertical line down the length of the fabric. One pattern unit 20, 21 and the mechanism operated thereby, serves to operate the needles of one feed and the sinkers of an adjacent feed.

Title: Improvements in or relating to spinning apparatus for artificial silk
IPC: D01D1/06
Filed: 1930-07-30
Abstract: <PICT:0352761/IV/1> Apparatus for making filaments.-In machines for spinning artificial silk, constancy of pressure at the spinning jets is ensured by interposing between the main supply pipe for the spinning solution and the separate spinning machine a pressure-reducing valve such as will reduce the pressure to a degree slightly above atmospheric pressure and preferably such as to correspond with the pressure drop in the filter.  To ensure greater uniformity in titre, the solution is preferably circulated in a closed cycle past a number of spinning points by means of a pump situated beyond the pressure-reducing valve and associated with a loaded release valve.  As shown, the spinning solution supplied under a pressure of several atmospheres through a main pipe b passes to a reducing valve c of the double diaphragm type, and is then circulated by a pump f through a closed circuit d past the spinning points g.

Title: Apparatus and method for testing logic circuits
IPC: G06F7/58
Filed: 1970-05-14
Abstract: 1291522 Testing digital circuits INTERNATIONAL BUSINESS MACHINES CORP 14 May 1970 [19 May 1969] 23368/70 Heading G1U [Also in Division G4] A logic circuit 20, Fig. 2, is tested by applying successive combinations of input signals to both the circuit 20 to be tested and a reference logic circuit 30 and, for each input signal combination, sensing the amplitude of the voltage at each pin of the circuit under test relative to upper and lower thresholds and comparing the sensed amplitudes with the signals at the corresponding pins of the reference circuit.  Applying the input signals. A pseudo-random number generator 10 produces a random sequence of 48-bit numbers which are applied to gating circuits in a buffer 70. The gating circuits are controlled by a register 60 such that the output of the buffer 70 changes from one number produced by generator 10 to the next in 48 steps, only one bit changing at each step. The 48-bit output of buffer 70 is applied directly to the reference logic circuit 30 and, via a pulse shaper and synchronizer 80, to the logic circuit 20 under test. The buffer 70 also includes, for each bit, provision for over-riding the signal from the random number generator and forcing a '1' or a 'O' to be applied in series with a resistor to the relevant pin, enabling selected input pins to be maintained at a constant level and ensuring that the output pins are correctly loaded. Comparing the output signals, Fig. 4. The signal from each pin of the circuit under test is applied to two threshold circuits 92, 94. If the circuit under test is satisfactory, a '1' output will exceed the upper threshold and a 'O' output will be less than the lower threshold and thus the output should never be between the two. The outputs of the two threshold circuits are compared with the output of the corresponding terminal of the reference logic circuit 30 in a circuit 41-45 which produces an error signal whenever there is a discrepancy between the two logic circuits, or the output of the circuit under test lies between the two thresholds. Such an error signal, unless suppressed by the absence of a 'test on' signal on gate 47, causes an OR gate 49 to provide an error warning which stops further testing. Checking of the input pins ensures that open or short circuits are detected.

Title: Improved apparatus for joining surfaces coated with adhesive
Inventor: HAWKINS WALLACE GERALD
IPC: B31B3/64
Filed: 1955-08-13
Abstract: 799,583. Seaming non-metallic sheet materials. CLARK, Ltd., C. & J. Aug. 8, 1956 [Aug. 13, 1955], No. 23374/55. Class 42 (1). [Also in Groups XVII and XXIX] An apparatus for joining surfaces coated with adhesive includes two workheads L, R each operable to close on a workpiece A, B and apply pressure thereto and which are arranged to be operated alternately through manually controlled means 22 adapted at each actuation to cause one workhead to close and the other to open. Each workhead comprises a lower fixed member 11l having a thermostatically controlled heater to activate the adhesive and a movable upper member 12l embodying a rubber cushion and connected to a pneumatic or hydraulic piston to apply pressure to the workpiece. These pistons are spring-loaded to the raised position and are alternately connected to the pressure fluid supply and to the atmosphere by a spring- loaded piston valve (not shown) operated by the pedal 22. Alternatively, the valve may be operated electrically from a foot switch or switches or may be replaced by a pair of valves actuated together but in opposite senses. The workpieces A, B may be cardboard boxes or cartons one of which is prepared on an adjustable table or tables 5 for insertion into the open workhead while the other is held by the closed workhead. Fig. 4 shows a modified apparatus in which the open workhead is closed by the insertion of a workpiece which opens a valve 44l through a device 45l so that pressure is released from one end of a valve 34 which is thus moved to close the open workhead and to connect the closed head to exhaust so that the latter is opened by its spring. A valve 48l, previously held open by the pressure in the line 41r, is now closed by a spring 49l so that pressure fluid from an inlet port 36 passing through a restricted passage 42 in the valve 34 balances the latter in readiness for the next reversal of the workheads. The valve which connects each head alternately to supply and exhaust may be actuated by a pair of solenoids which are alternately energized by the discharge from one of a pair of electrolytic condensers each of which is connected alternately to a charging rectifier and to the solenoid by switches arranged on the workheads for actuation by the workpieces.
