Title: Improved production of articles on superimposed cylinder knitting machines
IPC: D04B9/10
Filed: 1964-06-10
Abstract: A superpose cylinder machine has the knitting cams (31, 32, 36, 37) Figs. 2 and 3, not shown, for each yarn feeding station for the upper cylinder angularly displaced around the cylinder and in out-of-phase positions with respect to the knitting cams of the yarn feeding stations for the lower cylinder.  Purl fabric is thus knitted in an alternating course sequence such that after knitting at one station in one cylinder the needles are immediately transferred to the other cylinder to knit the next course and this sequence is repeated continuously.  The sliders are pivoted to release their needles by cams (38) and are permitted to pivot at their needle ends by recesses (28) formed in the cam systems.  The pointed ends of the sliders act as latch openers.  A retaining cam (29) is provided in the cam system of each cylinder to retain the needles in the cylinders as they move from one cylinder to the other and are coupled with the next operative slider.

Title: Improvements in and relating to clockwork switch devices for periodic absorption refrigerating apparatus
IPC: F25B49/04
Filed: 1935-08-29
Abstract: 462,297. Clockwork-actuated valves. SIEMENS-SCHUCKERTWERKE AKT.-GES. Aug. 29, 1935, No. 24185. Convention date, Sept. 7, 1934. [Class 135] [Also in Groups XXXVII and XIII] A refrigerator of the periodic absorption type has a clockwork actuated device for controlling the heating periods arranged so that the heating period can be adjusted from outside the casing. A disc 22 mounted on a spindle 11 is driven by clockwork (not shown) so as to rotate once in 24 hours and carries pins 23 which engage valve mechanism (not shown) to initiate the heating period. A hub 26 engages a long pitch thread on spindle 11 and is biassed to the right by a compression spring 28. Bearing on the hub 26 is a bridge 29 carried by a spindle 30 having screw threaded engagement with a nut fixed on the casing 21 and which is provided, outside the casing, with an adjusting knob 31. Rotation of the knob 31 causes axial movement of hub 26 which thus rotates relative to spindle 11 and varies the angular separation between the pins 23 and pins 24 on arms 25 carried by the hub 26. The pins 24 operate a valve to cause the termination of the heating period, which is thus varied by moving knob 31.

Title: Improvements in magnetically operated electric switches
IPC: H01H5/02
Filed: 1936-09-04
Abstract: 481,122. Magnetic and inertia switches. BRIGHT, H., and RICHARDS, A. F. W. Sept. 4, 1936, No. 24262. [Class 38 (v)] A switch which is held closed by the force of a permanent magnet has the armature normally resting just outside the range of attraction of the magnet so that a small relative movement of the magnet and the armature towards each other causes the armature to be attracted towards the magnet to operate the switch. As shown in Fig. 2 in which the switch is mounted within a lampholder 1, 2 which may be mounted on a floor or table standard lamp, a permanent magnet 4 is provided with two insulated pole pieces 5a, 5b which act also as fixed contacts. Normally resting in a recess 6 below the pole pieces and just outside their range of attraction is a ball 8 of magnetic material. If, however, the lamp standard &c. is shaken the ball 8 is moved into the range of magnetic attraction of the pole pieces and is rapidly attracted to them, as shown in Fig. 1, the polepieces being hollowed out spherically to receive the armature which also bridges the polepieces electrically and completes the lamp circuit. To disengage the armature and break the lamp circuit means such as a spring-retracted lever 15 may be provided which on depression engages the ball and returns it to the dotted position shown. An alternative method of returning the armature shown in Fig. 4 in which the switch is embodied in a pear switch consists in drawing away the loosely-mounted permanent magnet 4 from the polepieces by pulling the switch downwardly away from the flex by which it is suspended, the lower end of the flex 19 being looped around the magnet. The ball drops when the magnet is moved upwardly from the polepieces 5a, 5b, a spring 20 returning the magnet when the switch is released. Other methods are also described such as by diverting the flux from the ball armature by moving a soft iron bar across the magnet poles. The polepieces may be plated with silver, copper or other suitable material to minimize the effects of sparking.

Title: Digital frequency shift key modulator
IPC: H03C3/00
Filed: 1975-06-10
Abstract: 1477113 Waveform generators; digital-to-analogue conversion INTERNATIONAL BUSINESS MACHINES CORP 10 June 1975 [18 Sept 1974] 24770/75 Heading H3H An FSK modulator comprises an oscillator feeding a counting means controlled by a mark/ space input to count at different speeds and to provide gated outputs to a second counter controlling a synthesiser providing a stepped sine wave output. The stepped wave may be smoothed by a (linear phase) filter and the mark/input may also set different counts; the synthesiser may include a weighted D/A converter. A mark signal on line 28 enables flip-flop 32 which is set on the next negative transition from oscillator 34, which disables gates 44, 50 and enables gate 56 passing half rate (2 MHz) oscillator pulses from flip-flop 52 through OR 58 to 8 stage counter 62, currently set at an 104 division ratio (1200 Hz line signal on Bell 202 system) output being through AND 72 and OR 76 to a 4 stage counter 82 providing 8 steps up and down to control a translator 22 and weighted D/A converter 24 providing a 2 volt maximum output. In similar mode, a space signal resets flipflop 32 causing admission of full rate (4 MHz) oscillator pulses to counter 62 which is set (for Bell 202) at a division ratio of 114 (providing 2200 Hz line signal). Counts for other system frequencies may be set through lines 70a-70d. The digital-to-analogue converter, Fig. 2.- Transistors 101-104 and resistors 108-111 provide four independent current sources with further transistors 116-119 switching the currents additively through resistor 120 under control of inverted zero input signals on lines R1-R4. Further transistors 147-150 and resistors 153-156 compensate for inaccuracies due to base currents of transistors and voltage/ current parameters of Zener diode 140. The signals on lines R1-R4 are derived through 22 which translates the 8 step output of counter 82 to appropriate signals [see Table A (not shown) for correlation]. The linear filter (Fig. 3, not shown) includes an operational amplifier (170) with an RC feedback path (188, 190) to provide a smoothed wave on output line 30.
