Title: Moulded footwear
IPC: A43B7/32
Filed: 1969-11-11
Abstract: 1285594 Boots &c INDUSTRIEWERKE LEMM & CO GmbH 11 Nov 1969 [15 Nov 1968] 55109/69 Heading A3B An article of moulded footwear, e.g. a boot, is made by placing a lining 1 on a last (not shown), placing an intermediate layer 6 of cellular plastics material over the lining except in the region of the dividing line of the mould (not shown) and then injecting or press moulding the outer layer 7 of the boot. The lining may be formed from two blanks 1 which are joined in the region which is free from cellular material by two strips 4, 5 and seams 2, 3. When the material of the outer layer 7 is injected or pressed into the mould it initially flows along the regions which are free from cellular material which act as distribution ducts for the material 7. The material 7 then flows over the cellular layer 6 and compresses it so that when the boot is removed from the last the cellular layers 6 expand inwardly as shown in Fig. 2 to leave channels 15 which act as ventilation ducts in the boot. The insole is formed from a lining 9 (Fig. 1), two layers of cellular material 11 and a cover layer 10. A profiled outsole 13 is injection moulded onto the bottom of the boot.

Title: Apparatus for testing data transmission systems
IPC: H04L25/04
Filed: 1971-11-29
Abstract: 1371780 Digital transmission; testing ALITALIA LINEE AEREE ITALIANE SpA 29 Nov 1971 [23 March 1971] 55338/71 Heading H4P  An apparatus for testing a transmission system between two or more stations comprises means for repeatedly generating and transmitting a message simulating the call signal of each of the stations comprising fixed and settable characters and for receiving an answer signal, with a comparison of answer with a repeat of call signal, which process continues until stopped by an operator or an error is detected; an optional time delay may restart transmission. Signals arriving at terminal DR pass through inverter I1 connected to AND gate A1, also inverter I2 connected to comparator CPR comprising an exclusive OR gate. The first positive transition through A1 causes setting of a flip-flop FF2 which is connected to test character generator (see Fig. 7, not shown) also one input of AND gate A2 passing received clock pulses after inversion into the character generator (unreferenced). FF2 is also connected to a monostable circuit MS1 providing a start pulse to the generator. At this point received test character signals on terminal DR are compared in CPR with a locally generated character through inverter I4. If an error occurs on an input to AND gate A3, also receiving clock pulses, FF2 resets and disables A2. When a new incoming message is received the test is repeated. If correct an output is given on terminal F which enables AND gate A4 if FF2 is set hence FF1 is set which enables A5; through inverter I6 and switch S5, a request to send signal RTS is forwarded to the transmitter which responds by returning a "clear to send" signal CTS through S5 and inverter I7 to AND gate A6 resetting FF1 which blocks the RTS and hence CTS signals. In normal operation, with switch S2 closed, operation of multivibrator MV is inhibited, hence detection of an error causes the apparatus to be locked until a new message arrives. In a second mode, closure of switches S3a, S3b causes the same message to be continuously transmitted and a monostable circuit MS3, which is triggered at the end of each one, causes an interval between messages. Closure of switch S 1 causes issue of RTS, CTS signals as described above.

Abstract: 1,186,010. Electromagnetic switches; electric selectors. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP., and NIPPON ELECTRIC CO. Ltd. 8 Dec., 1967 [9 Dec., 1966], No. 55941/67. Headings H1L and H1N. To reduce the size of a co-ordinate electromagnetic switching array at least one sealed magnetic reed contact unit and at least one remanent core are mounted in each aperture of a flat strip 3 of magnetic material, the contact units of the strip are wound individually and continuously to form a row winding 6, a plurality of similar strips, e.g. 3a, 3b, 3c, 3d each with their contact units, remanent cores and row windings are assembled together to form a large flat magnetic plate and finally the lateral lines of contact units of the several strips are wound with common column windings 8. By this arrangement the distance between adjacent cross-points in a column, which is normally determined by the size of the winding head 10 for making the column windings around individual cross-points, is reduced. In the array shown, a pair of contact units is provided at each cross-point and each cross-point has a large row winding above the plate 3 series connected to a smaller opposing row winding beneath the plate and a large column winding below the plate series connected to an opposing smaller column winding above the plate. The cross-points are only actuated by coincident energization of all four windings. All of the winding spools may be moulded around apertures in a strip 3 in one moulding operation, or the spools may be moulded individually. In the latter case each strip is split longitudinally and the two halves are introduced into grooves in the spools so that they make engagement. Magnetic shields are placed between adjacent column windings of the array (Fig. 12, not shown).

Title: Improvements in and relating to alternator voltage regulation
Inventor: THOMPSON JAMES ELBERT
IPC: H02J7/24
Filed: 1968-11-29
Abstract: 1,246,993. Automatic voltage control. MOTOROLA Inc. Nov. 29, 1968 [Dec. 26, 1967], No. 56742/68. Heading G3R. In an automatic voltage control system for an alternator 10 whose rectified output 11 charges a battery 12 and whose field winding 13 is controlled in a cyclical ON/OFF mode by a voltage comparator circuit 36, a control switch 20 and an amplifier 16, the reference voltage for the circuit 36 is obtained from a circuit 60 dependent on the temperature to which the battery is subjected and comprising a temperature-responsive generator producing voltages over a range corresponding to predetermined upper and lower temperatures, so that the output voltage of the alternator 10, which oscillates between upper and lower limits corresponding to the on and off conditions of the field winding, varies in inverse proportion to the sensed temperature. Amplifier 16 is the ON/OFF transistor type as is the switch 20 which exhibits voltage hysteresis, thus producing a triangular rectified output voltage, Fig.2(not shown) oscillating between limits corresponding to the upper and lower limits of the alternator voltage. The reference voltage circuit 60 comprises a slope generator 61 which varies the reference signal to a differential amplifier 37 of the comparator circuit 36, this variation being limited at the predetermined upper and lower temperatures by clamping circuits 65, 64. Reference voltage variation is produced by the temperature reponsiveness of the base-to-emitter junction of a transistor 70 forming part of the generator 61 which is supplied with a voltage pedestal from a low reference voltage circuit 63 set by a high voltage reference circuit 62. The reference voltage varies inversely with temperature to provide a substantially linear characteristic, Fig. 3 (not shown) and effect a corresponding variation in the voltage limits set by the switch 20. The theoretical basis of the generator 61 is discussed together with a mathematical analysis of its component parts, Fig.4 (not shown). A diode 80 provides temperature compensation for the clamping transistor 81 of the circuit 65.

[Also in Division D1] Fabric for babies' napkins has a zone of pile disposed so as to form the middle of the folded napkin. The part that comes in contact with the skin is preferably hydrophobic and the fabric also contains hydrophilic fibres. If the fabric is folded to bring the pile to the interior of the napkin, the base fabric is hydrophobic and the pile is hydrophilic. If the pile is next to the skin, it may contain hydrophilic loops 33e<SP>11</SP>, Fig. 22, which shrink on laundering and hydrophobic loops 33e<SP>1</SP> which maintain their original height; or the pile yarns may have hydrophilic core sheathed with hydrophobic fibres. The base fabric may consist of two layers 43, 44, Fig. 5, the pile 35a passing through both layers which are thereby joined together but are left separate at the pileless zones 36a, 37a. A fabric, Fig. 23, having a pile zone 35f is folded as shown in Fig. 24 and stitched at 72, 73; a similar napkin can be produced if the pile zone is on the panel 31f. A two-layer napkin is produced from the fabric shown in Fig. 27 by folding the panel 31h over the pile 35h so that the pile is inside. If the panel 31h also has a zone of pile, the fabric is folded with the zones of pile on the outside; such a napkin can also be made from a piece of fabric twice as long as the napkin having a central stripe of pile.

Filed: 1971-12-08
Abstract: 1366945 Display apparatus R E STRICKLAND 8 Dec 1971 [9 Dec 1970] 56951/71 Heading G4H An opinion or personal data sampling apparatus 10, Fig. 1, comprises a projector illuminated screen for displaying a series of multiplechoice questions, buttons 19 for indicating an answer thereto, and means for returning to the beginning of the series if it is sensed that the questions are no longer being answered. The projector may be a circular slide projector and the sensing means may be a time-delayed relay 72, Fig. 3, which operates after a preselected interval if it has not been reset by a button 19. The circuit of Fig. 3 is actuated by means of a starting switch 18 whereupon the first question appears on screen 12. When an answer button 19 A-H is pressed, a signal is sent on one of lines A-H to a tape punch 46 and the slide magazine of the projector is rotated to the next slide, and hence the next question, this rotation causing the tape punch to advance. If a button is not pressed within the preselected interval, the timedelay device 72 causes the magazine to rotate right round to the starting point of the series, whereas pressing the button resets the device. A switch 83 is included so as to allow more than one answer to a question to be recorded by buttons 19 A-G (19H serving to advance the projector and the tape). At the end of the series, a counter 79 is incremented by means of a switch 34 operated by a projection on the slide magazine. The above embodiment envisages an 81-slide magazine containing four identical question series of twenty questions each; for series of arbitrary length, the magazine can be rotated backwards from any selected position by means of a flexible band 104, Fig. 6 (not shown), attached to a constant tension reel (105). The means for detecting that a series of questions is no longer being answered may alternatively comprise some means of detecting the presence or absence of a person, e.g. a pressureresponsive area or a photodetector. Additional apparatus, such as a camera and a microphone, may also be incorporated (for verification and for additional communication), and the tape punch may be replaced by magnetic storage, a telephone or a counter.

Title: Improvements in systems for controlling the direct current in the windings of an electrical machine
IPC: H02P6/08
Filed: 1969-11-26
Abstract: 1292119 Control of AC motors J SCHNEIDER 26 Nov 1969 [27 Nov 1968] 57932/69 Heading H2J The windings of an electrical machine are selectively energized with direct-current, means being provided to control the mean value of the current, reverse the current, and switch it from one winding to another. Two sets of supply thyristors T1-T3 and T<SP>1</SP>1-T<SP>1</SP>3 are connected between the windings I-III and the power supply, while free-wheeling thyristors t1-t3 and t<SP>1</SP>1-t<SP>1</SP>3 are connected to a line RL. A switch H receives a chopping signal when the line current deviates from a set value, and a switching signal dependent on rotor position in the ease of a synchronous motor. A smoothing choke has windings M, N, in series with the supply thyristors and the free-wheeling thyristors respectively. Alternatively, a multiwinding smoothing choke is associated with each winding of the machine. In another arrangement, the free-wheel line RL includes a capacitor shunted by a diode and adapted to be charged to a voltage higher than the supply-voltage. The capacitor is discharged by the firing of a free-wheeling thyristor to quench the supply thyristors, but current continues through line RL and the diode, Fig. 2 (not shown). Two free-wheeling circuits may be provided, the thyristors t<SP>1</SP>1-t<SP>1</SP>3 being replaced by diodes. In this case, power is returned to the supply after the capacitor has discharged. A rheostat provides braking. The free-wheeling circuit may comprise two capacitors each shunted by a diode and associated with respective windings of a choke. Each capacitor has an oscillatory circuit comprising a thyristor and a load choke.

A machine for automatically removing a worn thermoplastic cover 11 from a yarn or thread-winding roller 10 and applying a new cover 12 comprises a pair of carrier wheels 15 for lifting the rollers 10 from a tray 13 into alignment with a piston 21 that forces the roller 10 out of its worn cover 11 on to a conveyer 27 which raises the rollers into alignment with a piston 39 that forces the rollers into a new cover 12. The new covers 12 are lifted from a hopper 33 by a chain conveyer on to a shoot 32 on which they are heated by an infra-red lamp 51. The new covers 12 are lifted from the shoot 32 by carrier wheels 30A, 30B into alignment with the rollers 10. A piston 38 holds the covers 12 against a bush 43 whilst the piston 39 forces the rollers 10 into the cover 12. The carrier wheels 30A, 30B are intermittently rotated by a pneumatic piston 66 acting through a one-way friction clutch 67 on a shaft 27 on which the wheels 30A, 30B are mounted. The wheels 30A, 30B are held against rotation by a detent 68, 69 when the new cover 12 is aligned with the roller 10. The detent is released by a pneumatic servo 65. The carrier wheels 15 are rotated and held by a similar pneumaticallyoperated ratchet and detent device 73 . . . 75. The worn covers 11 removed by the piston 21 are dropped into a basket 52 and a piston 53 forces the covers between intermeshing gears 56 which flatten the covers. On closure of a switch 81, Fig. 3, a contact 78 sequentially engages contacts I ... IV. When the contact 78 engages the contact I it energizes an electromagnetically operated valve V 1  to supply y pressure air to the detent release servos 65, 71. Thereafter the contact 78 engages contact II to energize valves V 2 , V 3  which supply pressure air to servos 66, 72 to rotate the carrier wheels 15, 30A, 30B and align a roller 10 with the piston 21 and a new cover 12 with a stripped roller. Further rotation of the contact 78 to engage contact III energizes valves V 4 , V 5  which supply pressure air to the pistons 21, 38, 39 respectively forcing a roller from its worn casing and forcing a roller into its new casing. When the contact 78 engages contact IV the pistons 21, 38, 39 are returned to the position shown and a valve V 6  is energized to supply pressure air to the piston 53 which forces the worn cover through the gears 56. The above cycle is repeated whilst the switch 81 is held closed.
