Patent GB-1586646-A (GB)
Title: Artifical tooth
IPC: A61L27/46
Filed: 1978-04-17
Abstract: An artificial tooth with an implantable root adapted to permanently grow together with the jawbone and, also under high mechanical loads as is the case for natural teeth, will not allow for the production of a rejection or repelling reaction between the natural bone and the implant. The tooth root is essentially constituted of a biostable polymer matrix which is compatible with human tissue, in which there is introduced reabsorbable bioreactive calcium phospate in a finely dispersed form, which is encompassed by a thin porous layer of non-reabsorbable calcium phospate, and into which there is inserted a core as a connecting member for the mounting of a dental superstructure in the form of a tooth crown, a fastening element for dental bridges or the like. In the region of the tooth neck which is encompassed by the gingiva, an intermediate member is located between the tooth root and the superstructure, which is formed of tissue-compatible material and which supports the close contact of the gingiva, and by means of which the dental superstructure is connected with the tooth root in a shock-absorbent manner.

Title: Improvements in Electromagnetically-actuated Switches.
IPC: H01H50/32
Filed: 1919-06-16
Abstract: 128,562. British Westinghouse Electric & Manufacturing Co., (Assignees of Camp, R. E. de). June 21, 1918, [Convention date]. Electro - magnets. - Electromagnetic switches have a number of contractor armatures 6<a>, 6<b>, 6<c>, which are held in the open position by a cross-bar 11 carried on a non-magnetizable, spring-pressed rod 8, when the coil 4 is de-energized. At full current, an armature 5 attracted by the coil lifts the rod. The contactor armatures are then held by the coil until the current falls, the armatures going up in succession at different current values; the points at which this happens are determined by the adjustable springs 30 and adjustable air gaps 34. The armature 5 is held up to the rod by a spring 15 surrounding its pivot shaft; this armature may carry a switch contact 39. The coil is carried by two brackets 2, 3, the latter having two projections 9, 10 forming pole-pieces for the armatures. Screws 33 provide means for adjusting the air gaps 34. A rod 35 on the bar 11 passes through the projection 10 and prevents turning of the bar. As modified for use with alternating current, the core 55, Fig. 7, of the coil is slotted as shown. The brackets 2, 3 are formed of coarse laminations, into which are inserted shading coils to stop chattering. The air gaps are formed between the contactor armatures and adjustable screws on the bracket 2.

Abstract: 612,247. Controlling aircraft. SOC. CIVILE D'ETUDES DE CONSTRUCTIONS AERONAUTIQUES (E.C.A.). May 21, 1946, No. 15384. Convention date, May 28, 1945. [Class 4] Relates to airplanes with automatic piloting or robot devices wherein the adjustment of control surfaces of the plane is derived from the responses of gyroscopes and consists in a turn-controlling device comprising a pivotallymounted frame or cradle which supports gyroscopes automatically controlling pitching and yawing movements respectively, the pivots of the frame having an axis parallel to the rolling axis of the airplane, and means under control of the pilot to move the pivotally-mounted frame or cradle in order to impress upon it angular displacements equal and reverse to the angle of the rolling position of the airplane required for making the intended turn. In the construction shown the cradle A, which carries a rolling movements control gyroscope in addition to those for controlling pitching and yawing movements, can be turned about axis A 1 by means of motor B which rotates screw C in a nut D pivoted on the cradle; the motor can be controlled to rotate in either direction by a pilot-controlled switch (not shown). The turning of the cradle causes the rolling movements control gyroscope to impart to the airplane a transverse inclination in the reverse direction to the cradle turn and of equal magnitude. The electric circuit shown is intended to exert a correcting force upon the yaw control gyroscope dependent upon the angle of turn of the cradle and upon the speed of the plane as obtained from the pilot tube shown as controlling a potentiometer H through a cam J and lever L.

Title: Improvements in vacuum tubes
IPC: H01J19/68
Filed: 1923-06-14
Abstract: 221,855. Robinson, E. Y. June 14, 1923. Addition to 195,691. Vacuum tubes.-In a valve of the type described in the parent Specification, the space current is not completely confined to the narrow interelectrode space, and the unconfined portion of the discharge is so limited that it has a negligible effect on the main portion of the discharge and on the main portion of the cathode. For the purpose the shields referred to in the parent Specification may not be wholly effective in preventing fringing, or may be operated at such a temperature that a certain amount of emission takes place from them, or the shields may be omitted and the shielding obtained by cooling the ends of the cathode which extend outside the anode, or by forming them of larger dimensions, so that the rate of evaporation and disintegration of the ends due to positive ion bombardment does not exceed the rate of evaporation of the portion of the cathode producing the main discharge. In one arrangement, Fig. 2, a straight filament 1, mounted at one end on a support 2, and guided at the other end by a hole in a support 4, as described in Specification 222,176, is cooled by the support 2 and by a strip 6 connected with another filament. The anode 7 consists of a long cylinder closely surrounding the filament. Dimensions of the anode and filament are given. Curve 9 shows the temperature along the filament and curve 8 the electron emission, the fringing current being indicated at 10. In the arrangement shown in Figs. 3 and 4, two filaments 1 are mounted at one end on supports 2, and at the other end pass through holes in a registering member 8, and are connected with a cross-piece 5 and held in tension by a spring 7. A bridge-piece 9 short-circuits the ends of the filament and acts as a cooling member. The support 6 for the spring 7 is mounted on a frame consisting of vitreous or other insulating members 10 mounted on a member 11 clamped to a re-entrant tube 4. The anode consists of two plates 12, shaped to form two tunnels enclosing the filaments, and supported on the members 10 by crosspieces 13. In another arrangement a tubular cathode of the type described in Specification 205,613 is arranged so that the rate of disintegration of the ends is about the same as that of the centre portion. A grid may be provided in all of these arrangements. Specifications 182,431 and 220,747 also are referred to.
