Title: Improvements in and relating to electrical musical instruments
IPC: G10H3/24
Filed: 1937-10-22
Abstract: 510,349. Electrical musical instruments. RUDIN, R. POLLAK-, and WERNDL, E. Oct. 22, 1937, No. 28877. Convention date, Oct. 23, 1936. [Class 88 (ii)] In an electrical musical instrument wherein an electric pulse from a condenser electroinagnetically or electrodynamically &c. causes oscillations in a mechanically oscillatable body (solid, liquid or gaseous), means are provided for controlling the amount of charged or discharged energy in accordance with the velocity of operation of a key or the like. In Fig. 1 a key 17 normally closes a contact 3 charging a condenser 2 from a directcurrent source 1. Depression of the key breaks contact 3 and makes a contact 4, enabling the condenser to discharge through an electromagnet 6 which sets the steel tongue 7 vibrating. The intensity of vibration is however reduced according to the time taken by the key in passing from contact 3 to contact 4, during which the condenser, is partially discharged through a resistance 11. In Fig. 3 (not shown), the resistance 11 is connected in circuit by a third contact made by the key before it contacts with contact 4. In Fig. 2 (not shown), charging current, instead of discharging, is passed through the electromagnet, three contacts co-operating with the key. In place of electromagnet actuation of a tongue 7, an electrodynamic arrangement may impulse a column of air. The charging or discharging may take place as a damped oscillation tuned to the periodicity of the oscillatory body, by which means harmonics may be emphasised. Electromagnetic electrostatic or other pick-up devices, leading to amplifiers and loud-speakers, may be added. Groups of tongues, strings, bells &c. may be used, non-magnetic bodies having armatures attached if they are to be driven electromagnetically. An electromagnet may be movable relatively to the body it vibrates, or a number of electromagnets actuated alternatively or simultaneously may be used for one body. Variable damping at certain points may be effected with felt or rubber. Contacts may take the form of controllable gas discharge paths, spark gaps, or discharge paths in vacuo. The Specification as open to inspection under Sect. 91 comprises also arrangements in which the condenser discharge is independent of the speed of depression of the key; the use of energy accumulated in an electromagnetic field in lieu of the condenser; a tremolo make-and-break, (Fig. 7, Cancelled, not shown); a system of switching (Fig. 8, Cancelled, not shown) by which, in an instrument, o'nly as many condensers. are employed as the number of notes required to sound simultaneously; together with photographs showing details of a complete instrument. This subject-matter does not appear in the Specification as accepted.

Filed: 1938-10-07
Abstract: 519,983. Discharge apparatus; paints. PULESTON, R. Oct. 7, 1938, No. 29051. [Class 39 (i)] [Also in Group III] A coating for the envelope or other parts of electron discharge tubes consists of a suspension of a conductive material, such as graphite, in an extending liquid, e.g. water, with a dispersing medium comprising a large proportion of ultra-microscopic particles of an inorganic nature. Such a dispersing medium consists partly or wholly of a clay, such as bentonite. In addition to graphite other conductor powders such as carbon black, or metals in a finely divided state may be used and non-conducting powders such as silica may be added. The viscosity of the extending liquid and the tenacity of the film may be regulated by the addition thereto of soluble substances such as an alkali metal hydroxide, silicate, phosphate or other inorganic salt. For cathode-ray tubes and other devices where reflection of light is undesirable, the graphite used is preferably in finely divided form and not in large flakes, but does not necessarily consist entirely of colloidal particles.

Title: Improvements in the construction of and methods of producing inductance coils
IPC: H01F27/00
Filed: 1937-10-26
Abstract: 504,201. Inductances. PORZELLANFABRIK KAHLA. Oct. 26, 1937, Nos. 29268 and 29269. Convention dates, Oct. 26, 1936, and Oct. 27,1936. [Class 38 (ii)] Inductance coils, particularly for highfrequency work, are formed by coating with metal, e.g. silver, gold, platinum or copper helically or spirally arranged turns 11 formed of ceramic material. The ceramic body is first produced as an internally or externally grooved cylinder, Fig. 4,. or a grooved disc, Fig. 13, and the backing is then removed either before or after hardening and final firing by grinding, turning, &c. to leave separated turns, the metal then being preferably burnt on to one or more faces of the turns. The latter may be supported by spacing members or comb-like structures inserted between and glazed to the turns. Alternatively, an internal or external supporting cylinder may be employed, and in the latter case a metal coating may be provided on the cylinder to form an electrostatic screen. The invention may be applied to variometers by making the turns of the coated ceramic body conform to a sphere, Fig. 17. The value of the inductance may be adjusted after manufacture by compressing the turns in the case of the helical form either by a central screw 114, Fig. 19, or by screws bearing on a movable end piece 122 of a screening housing 123, Fig. 21. In the spiral form, adjustment may be effected by circumferential displacement of the outer end of the spiral on its supporting base 131, Fig. 24, or by turning a central squared spindle 136, Fig. 26, engaging the inner end of the spiral, the outer end being anchored at 135.

Title: Improvements in or relating to the feeding and registration of sheets in printing or like machines
IPC: B65H9/12
Filed: 1953-10-23
Abstract: 802,903. Feeding sheets. WAITE & SAVILLE, Ltd., and WHYTE, F. Oct. 25, 1954 [Oct. 23, 1953], No. 29273/53. Class 100(1) In an intermittently-rotated feed gripper mechanism for feeding sheets registered on a feed-board to a gripper cylinder, the grippers are registered and held in the sheet-taking position by means of a register stop, pivotally mounted on the frame of the mechanism, which co-operates with a register stop associated with the feed gripper shaft. The means for operating and registering the grippers is described as applied to the apparatus disclosed in Specification 602,285. During each complete rotation of the impression cylinder 3, intermittently-rotating feed grippers 1 are arranged to travel slightly in advance of the front edge of a sheet which is registered on a feed board, the grippers are then opened and rotated in the reverse direction to an accurately registered position where they seize the sheet, the front lays are moved clear, and the grippers are accelerated up to the same peripheral speed as the impression cylinder 3 to which the sheet is transferred, and are then decelerated. The grippers 1 are mounted on a shaft 2 housing a segment or quadrant gear 6 meshing at times with a gear 5 on the shaft 4 of the cylinder 3. Cams 7, 8 on the shaft 4 co-operate with runners 11, 12 respectively, mounted on the shaft 2 to cause the latter to be accelerated and decelerated, and these cams operate in opposition to cam faces 13, 13a on a control cam 14 on the shaft 2. The runner 11 is mounted on the gear 6, and the runner 12 is carried on a two-armed lever 15 loosely mounted on the shaft 2 and maintained in position against a stop 16 on the gear 6 by a spring device 17 carried on the shaft 2. The grippers 1 are accurately registered in the stationary sheet-taking position by means of a camoperated stop 18, pivoted at 19 on the machine frame, having a runner 23 adapted to be engaged by a cam incline 22 on the shaft 4. This stop 18 is engaged by an abutment 21 secured to the gripper shaft 2, the latter being urged in the reverse direction by the action of the spring device 17, the runner 11, and reversal cam 7. The runner 23 on the stop 18 is urged towards the cam 22 by a spring 20. The stop, cam, and gears &c. are' all mounted in a casing 24 which constitutes an oil bath.
