Abstract: 1356190 Heart stimulator AMERICAN OPTICAL CORP 14 Sept 1971 [14 Sept 1970] 42852/71 Heading A5R A heart stimulator for treating "paroxysmol supraventricular tachycardia", a sudden attack of rapid heart action, comprises a pulse generator for supplying a burst of electrical stimuli at a continually changing rate above 160 pulses per minute. The stimulator comprises a reed switch 32, with a reed 31 movable by a manually manipulable magnet from a "normal" position as shown in Fig. 2, to an operational position in which it contacts the terminal 29. In the "normal" position a capacitor 28 is charged by batteries 3 to 7, via a resistor 23, whilst a further capacitor 65 is charged by the batteries via resistor 24, electrodes E1 and E2, the heart 14 and the return path to the battery 3. When the reed 31 engages the terminal 29 the capacitor 28 discharges through diodes 27 and 28, and a resistance 25, and also through resistors 35 and 37, capacitor 57, and resistors 61 and 63, whereby the capacitor 57 is charged. When the potential of the emitter of a transistor T7 exceeds that at its base by approximately ¢ volt, the capacitor 57 discharges through the transistor T7 and a further transistor T8 and resistors 61 and 63 until the difference between the potential of the emitter and base of transisor T7, no longer renders the transistor conducting, whereby the capacitor 57 is once more charged from capacitor 28. During each oscillation an increased potential is produced at the base of a transistor T9 due to the discharging of capacitor 57, and this transistor is allowed to conduct causing the capacitor 65 to rapidly discharge through the heart. A typical frequency of oscillation is said to be 1000 cycles/minute.

Title: Improvements in and relating to electrolytic cells
IPC: C25B9/19
Filed: 1964-10-21
Abstract: A diaphragm electrolytic cell comprises an alternating succession of anodes and cathodes in the form of alternate wedges all of the same angle, each anode being fitted in the space between two contiguous cathodes so that the distance between the parallel faces of the electrodes is determined by the penetration of a series of electrodes of the same sign into the space between the other electrodes.  As shown in Fig. Ia, graphite anodes 1 may be suspended with their ridges horizontal pointing downwards by current-carrying stems 2 adapted to slide in the cell cover 3 by a graphite torus 4 to allow vertical displacement of the anodes during electrolysis, while the metal cathodes 5 carrying the diaphragm 6 are fixed with their ridges horizontal pointing upwards and parallel to the ridges of the anodes. The cathodes may be attached to two half-slides mounted in the cell frame and which can be pulled out from two opposite side walls (see Fig. IIc, not <PICT:1014807/C6-C7/1> shown).  Alternatively, the electrodes may be arranged with their ridges vertical with the anodic and cathodic cases being mounted in the cell frame in the form of slides (see Fig. IIIc, not shown).

Title: Magnetic tape apparatus and methods of correcting head to track alignment
IPC: G11B15/18
Filed: 1974-10-04
Abstract: 1455890 Automatic control systems INTERNATIONAL BUSINESS MACHINES CORP 4 Oct 1974 [12 Nov 1973] 43075/74 Heading G3R In magnetic tape apparatus with a rotating (read/write) head, alignment between the head and oblique data tracks on the tape is measured using a longitudinal reference track having a constant frequency pattern interrupted by marks, of a different pattern, associated with the data tracks. The longitudinal tape position is changed to correct for any misalignment. As shown, head 13 moves for example along path 55 across the reference track 50 with a constant frequency pattern 51 and synchronizing marks 52, 53 associated with data tracks. As the head passes the bottom of the tape, the amplified head signal goes above a threshold in detector 59, to enable a counter 61 to count up pulses from clock 67 or shaped pulses from the pattern 51. The count is reversed at synchronizing mark 53 and stops when the top edge of the tape is passed. The resultant count which is dependent upon the head/ data track alignment is compared with a desired count from 141 and any difference used to change the longitudinal tape position by varying the excitation to a tape drive.motor, and thus to correct any misalignment. Whilst measuring the alignment the tape may be driven slowly or be stationary between steps. The synchronizing marks 52, 53 may be of double frequency or blank. To control tape tension the apparatus Fig. 1 (not shown) includes an automatically controlled tape loop in a vacuum buffer. In an alternative Fig. 9 (not shown), the count is started and stopped as adjacent marks are detected, and the count reversed as the peak head signal is passed or when the signal exceeds a given threshold. The skew of the head/data track may also be measured Fig. 12 (not shown) using a reference track at both ends of the data track.

Title: Pharmaceutical coating compositions
IPC: C09D133/14
Filed: 1959-12-18
Abstract: Coated, orally administrable pharmaceutical preparations, e.g. p tablets and pills are coated by conventional methods with a resin obtained by the copolymerization of 20-80% by weight of an amino-ester of acrylic or methacrylic acid and 80-20% of a second polymerizable monomer which per se forms a water insoluble polymer. Specific examples of amino-esters given are those of acrylic and methacrylic acid with N,N - dimethyl- and diethyl - b  - amino ethanol, N,N - dimethyl - amino - propanol and b  - hydroxy - N - ethyl - morpholine.  As comonomers are mentioned lower esters of acrylic and methacrylic acid, e.g. with aliphatic alcohols of 1-10 carbon atoms, styrene, acrylonitrile and vinyl acetate.  More than one member of each type may be used in admixture and plasticizers, flavouring and colouring agents may be added.  The polymerization is preferably carried out in an inert organic solvent (examples given) in the presence of a non-peroxidic compound yielding free radicals, e.g. azo-diiso-butyric acid nitrile and the solution diluted to a concentration suitable for coating.  The coating is stated to be generally water-insoluble but soluble in the acid medium (pH 2-6) of the stomach.

Abstract: 1367214 Digital transmission; teleprinters SIEMENS AG 20 Sept 1972 [4 Nov 1971] 43439/72 Heading H4P The direction in which a cylindrical typecarrier TT in a teleprinter should be rotated to reach most quickly its desired new position is determined by first simulating its rotation in a fast counter PZ. The angular position of the carrier TT is conveyed by a pulse disc TS to a first counter BZ which stores its initial position in the form of a five bit code. When a new required position is called for by a corresponding 5-bit code received at a shift register ER, gates G2 respond to a control unit ST and transfer the contents of BZ to the fast counter PZ. High frequency pulses (200 kHz) then step the counter PZ until either identity of the state of PZ with the received code at ER is detected by a comparator V, or else the number of h.f. pulses (counted at TZ) reaches half the number of type positions on the carrier TT (e.g. 16), whichever occurs first. If identity is reached first, the output of a trigger K remains unchanged, and a signal V 0 /R enables a gate SST to pass stepping pulses to a stepping motor SM to drive the carrier TT in a forward direction (corresponding to that simulated in PZ). If identity is not reached first, counter TZ causes trigger K to change state and this causes the stepping motor SM to be driven backwards. During the actual stepping of the carrier to its new position, the contents of counter BZ are compared directly in V with the received code at ER, and when identity is reached, stepping stops and a signal A initiates printing of the appropriate character.

Filed: 1959-12-22
Abstract: 895,999. Automatic control systems for gyroscopes. NORTH AMERICAN AVIATION Inc. Dec. 22, 1959, No. 43481/59. Class 38 (4). [Also in Group XX] In a gyroscopic system, the direction of spin of the rotor of a gyro is reversed while the gyro is caged by a servo-system, and a signal corresponding to that required to cage the gyro when it is stationary during reversal is stored and subsequently used to determine the torque applied to the gyro to eliminate drift. In Fig. 3 a drum controller 20, continuously rotated by a synchronous motor 21, alternately selects signals from an E- type pick-off 9 or 11 of a gyro 1 or 2, respectively, to control, through an amplifier 22 or 23, a torque motor 13 to maintain a platform 4 in a fixed position about an axis 3. During the periods that each gyro is not controlling platform 4 the drum controller 20 connects the pick-off 9 or 11 of that gyro to control, through amplifier 24 or 25, a torque motor 10 or 12, on the same axis as the pick-off, to cage the gyro. At the same time, the drum controller 20 reverses the connections to the three-phase rotor of the idle gyro so that it is braked, stopped and accelerated in the reverse direction. During the time that each gyro is stopped the drum controller 20 connects the caging signal output from amplifier 24 or 25 through the appropriate amplifier 36 or 37 so that follow-up servomotors 34, 35 adjust potentiometers 31, 32 to positions corresponding to the standstill caging torques of each gyro. Then, when each gyro is effective to control platform 4 the signal from the appropriate potentiometer 31 or 32 is applied to the appropriate torque motor 10 or 12 to eliminate drift. Specification 820,480 is referred to.
