Title: Magnetic logical device
Inventor: MORRIS DAVID JOSEPH
IPC: H03K19/166
Filed: 1963-08-09
Abstract: 1,055,894. Circuits employing bi-stable magnetic elements. ENGLISH ELECTRIC CO. Ltd. Aug. 7, 1964 [Aug. 9, 1963], No. 31497/63. Heading H3B. [Also in Division H1] A magnetic logical device comprises an annulus of rectangular loop magnetic material the inner perimeter of which defines a minor aperture and the annulus having three major apertures which are disposed at substantially equal intervals around the annulus. In the arrangement of Fig. 1 performing the AND function a pulse in reset winding 21 sets up a flux pattern in parts 15, 16 which is clockwise with respect to minor aperture 11 and a flux pattern in part 17 which is counter-clockwise. When a priming pulse is applied to prime winding 22 such as to tend to set up a flux acting around the minor aperture 11 in a clockwise direction the flux paths around the major apertures 12, 13, 14 will not be affected and no output signal will be induced in output winding 23. If, however, input signals are applied to input windings 24, 25 so that the flux directions around apertures 12, 13 are simultaneously clock-wise then the field caused by the priming current pulse will set up a flux round aperture 11 in a clock-wise direction. On the occurrence of the next reset pulse the flux in part 17 will be reversed and an output signal will be induced in output winding 23. If one of the input signals is missing the priming current cannot cause the flux to act round aperture 11 in a clockwise direction so that no output signal is produced by the subsequent reset pulse. To prevent back flow of data when more than one device are connected together a hold winding is wound on part 17 which sets up a field acting in a clockwise direction around aperture 14 when multi-aperture core 23A linked with the output winding 23 is reset. Alternatively a second prime winding may be linked with the input aperture of the following device. Fig. 2 shows a HALF-ADDER, and includes a further output winding 26 wound in series opposition round parts 15, 16. As in the case of Fig. 1, an output signal is induced in output winding 23 only when input signals A, B are applied simultaneously to windings 24, 25, which signals reverse the flux set round apertures 12, 13 and reverses the direction of the flux in 17. The output signal at winding 26 represents the EXCLUSIVE-OR function of the input signals A#B + #AB and the output signal at 23 may be defined as AB. By using combinations of input windings the output signal can be made to depend upon more than two variables. Non- destructive read-out of the data in the device of Fig. 1 may be achieved by energizing prime winding 22 with an alternating current of limited amplitude.

Title: Improvements in apparatus for joining together or anchoring the ends of stranded wire cables
IPC: H01R4/50
Filed: 1930-10-21
Abstract: 365,200. Rope couplings. HIGHFIELD, J.. S., 36, Victoria Street, London. Oct. 21, 1930, Nos. 31592/30 and 1928/31. [Class 109.] Wire cables or ropes are gripped by means of a split cone 6, Fig. 3, which is also split longitudinally by a number of splits not extending the whole of its length, and has a cylindrical bore with teeth 8 progressively increasing in depth. A co-operating sleeve 11, Fig. 5, has an internal taper less than that of the cone and when it is pressed into position the segments of the cone are forced in so that the teeth bite into the cable 10. Any pull on the cable tends to force the cone farther into the sleeve. In a modification shown in Fig. 9 the external taper of the cone is the same as the internal taper of the sleeve 11 and the bore is made conical for part of its length and provided with teeth 22 progressively increasing in depth. When the cone is placed on the cable the segments are sprung out, making the external taper blunter than that of the sleeve, which, when it is forced into position presses the segments in and causes the teeth to bite into the cable. When a cable having several concentric cores requires to be connected, a cone and sleeve is used for each core.
Patent GB-396969-A (GB)
Title: Process for removing acid constituents from gases, and rendering said constituents utilisable
IPC: B01D53/50
Filed: 1932-11-09
Abstract: Gases containing relatively small amounts of acid constituents in a gaseous or finely divided liquid or solid form are caused to act on aqueous suspensions of residues from the complete or partial combustion of fossil fuels, whereby the acid constituents are extracted and converted into salts principally of aluminium, iron and calcium.  Grate residues or flue dust from the combustion of brown coal or pit coal may be employed.  The acid constituents referred to are hydrogen chloride, hydrogen fluoride, sulphur dioxide, sulphur trioxide, nitric acid and silicon tetrafluoride. The process may be carried out at temperatures of 40-60 DEG  C. or higher and the gas should be brought into intimate contact with the aqueous suspension, for example by the employment of reaction towers traversed by the gas and irrigated by the suspension or by introducing the suspension in an atomized form.  When extracting sulphur dioxide from gases also containing oxygen, residues which contain compounds of iron or manganese may be employed which act as oxygen carriers and result in the production of sulphates. According to examples, (1) a furnace gas containing sulphur dioxide is washed at 50 DEG  C. with an aqueous suspension of a flue dust; (2) a gas containing hydrofluoric acid or silicon tetrofluoride is washed with an aqueous suspension of coke ash; (3) a gas containing hydrochloric acid is washed with an aqueous suspension of brown coal ash.  The Specification as open to inspection under Sect. 91 comprises also the employment in the process of other substances containing aluminates with or without silicates which have been produced in a fusion or combustion process, for example fused cements or slags such as blast furnace slag.  This subject-matter does not appear in the Specification as accepted.

Title: Device for imparting to a body a rapid striking movement
IPC: B06B1/10
Filed: 1926-12-14
Abstract: 263,147. Ohlsen, O. A. L. Dec. 15, 1925, [Convention date]. Machinery, utilizing inertia to obtain movements in.-In means for imparting a sharp movement in one direction to a body free to reciprocate or oscillate, the body is connected to or coacts with a rotatable member eccentrically loaded, as by spring, gravitational, or centrifugal force, in such manner that the member, by cooperation with driving-means and with the movable body, which is stopped in one extreme position, is caused to store potential energy by turning into an unstable position, and then to deliver the energy by a rapid rotation to a stable position. In one form utilizing centrifugal force, the reciprocating body 1, Fig. 5, is slidably keyed in a fixed guide 11 and is threaded to engage one or more worm-wheels 2. revolubly carried on a frame 6 on a driving-shaft.3. The wheels 2 carry masses 5, which, under centrifugal force due to rotation of the shaft 3, tend to maintain the outward position shown, so that the wheels 2 act as a nut to move the body 1 to the right, until it strikes an abutment 4. The wheels 2 are then rotated on their axes 17 until the masses have passed through their innermost positions, when they sharply return to the stable position, the body 1 being impelled by rack-action against a tup 9, which may be. provided with a spring 14. In a modification, the eccentrically-loaded wheel or wheels 2 engage an oscillating body 1, Fig. 6, which is in the form of a spur-wheel, located axially by a collar 20 and threaded to engage the non-revoluble spindle 7 of the tup 9. The wheel 1 rotates with the parts 3, 6 until the tup 9 abuts against the collar 20, when the wheels 2 are turned on their axes 18 and cause a rapid reverse rotation of the wheel 1 as soon as the centrifugal masses (not shown) have passed through the unstable position, thereby sharply impelling the parts 7, 9 to the left.. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a reference to devices using spring, gravitational, and centrifugal force in combination. This subject-matter does not appear in the Specification as accepted.
