Title: Improvements in or relating to the assemblage of groups of electrical contacts for musical instruments and for other purposes
IPC: H01H1/28
Filed: 1932-10-05
Abstract: 408,314. Keyboard switches. HALL, N., Westgarth, Lyndhurst Grove, Low Fell, Co. Durham. Oct. 5, 1932, No. 27707. [Class 38 (v).] Compactly arranged wire contacts for organs, telephone selector switches &c., are spaced and insulated in cells constituted by insulating laminµ separated by smaller plates forming distance washers. The insulating laminµ may be of bakelized paper, and may be threaded on rods alternately with the distance washers and clamped up. The distance washers may be of metal. Or the laminµ and distance washers may be of cellulose acetate and joined by solvent such as amyl acetate or acetic acid. In Fig. 1 the longer laminµ 1 and shorter distance washers 2 are strung on metal rods 3, 4, the laminµ 1 resting on the tongue 8 of a wooden rail to which they are further secured in groups by screws. The contact wires 5 with bent ends 5<a> are held by ebonite rods 6, 7 passing through laminµ 1, against the rear ends, and the underside of tips 2<a> on the front ends, of the washers 2. For key contacts a common bar coacts simultaneously with all the wires of a group ; in crescendo pedal actions and for telephone selector switches the wire contacts function consecutively, for instance by means of a coarse helix on a barrel. In multiple switches for controlling stops and couplers, each wire coacts with its own particular note bus-wire. In the coupling switch shown in Fig. 4, insulating plates 13 on rods 14, 15 are spaced by metal washers 17 and plates 18, the plates 18 having lugs 18<a>, 18b, preferably staggered, for connection to bus-wires 19. The contact wires 20<a> mounted on a bar 21 work between projections 13<a> on the plates 13 and are depressed (against the action of springs 35 and a rod 34) into contact with the tips 18<c> of the plates 18, by an insulating strip 21<a> rotated by means of an arm 25. In an alternative form of multiple switch, Fig. 5, the plates 18 are, through wires 27, maintained in electrical connection with metal washers 28 on a spindle 29. The contact wires 20<a> work between larger insulating washers 32 separating the washers 28, being allowed to contact with the washers 28 on rotation of the spindle to depress an ebonite rod 33 carried thereon. Specification 388,750, [Group XXXIX], is referred to.

Title: An improved method of winding yarn or thread packages
IPC: B65H54/10
Filed: 1939-10-12
Abstract: 528,238. Yarn or thread packages. ABBOTT MACHINE CO. Oct. 12, 1939, No. 27752. Convention date, Oct. 22, 1938. Addition to 456,799. [Class 120 (iii)] A yarn or thread package wound as described in the parent Specification has the slow traverse layers wound in conical shape, the quick-traversed crosswound portion of the package may be at the base of the package or at the tip thereof or at both the base and tip. As shown, the package is formed on a cylindrical tube 11, Fig. 2, and the winding is begun by a few quick-traversed cross-wound turns near one end 1 of the tube which is to form the base of the package ; the yarn is then traversed for a short distance with a slow traverse towards the other end 2 of the tube and back to the zone a where another few quick-traversed crosswound turns are laid, the yarn being then traversed onto a slow traverse slightly further towards the end 2 of the tube. This sequence of a number of turns of quick-traverse winding in zone a followed by a slow traversing of the yarn into zone b for an increasing distance each time is continued until the yarn in zone a is built up to its full diameter as shown and thereafter the yarn is slowly traversed on the conically wound nose 3 with gradually shifting traverse until the end of the nose reaches the end of zone b. If desired the winding can be continued by traversing the yam in zone c with a quick traverse cross wind as shown in Fig. 4 until finally a cylindrical package having quick-traverse cross-wound portions at the ends of a slow traverse winding in conical layers is obtained. If a bobbin with a conical base is used the first portion of the winding shown in Fig. 2 may be omitted and a conically-shaped package may be obtained by winding on a conical tube.

Title: Improvements relating to machinery safety guards
IPC: F16P3/08
Filed: 1923-11-05
Abstract: 207,516. Leister, A. F. Nov. 23, 1922, [Convention date]. Interconnecting guard with starting-gear.-In safety guards, particularly for machines having rollers such as roller breaks and sizing-machines, a lock disc, rotatably mounted on the machine and controlled by the reversing-gear coacts with projections on pivoted guards mounted at the two ends of the machine in such manner as to lock the guard at the feed end and free the guard at the delivery end, in whichever direction the machine is running. As applied to a reversing break, pivoted guards 14, 15 are mounted at both sides of the rollers 28, 29 and are furnished respectively with projections 20, 21 co-operating with a locking disc 8. The disc is linked by connections 22 - - 26 to a shaft 27 carrying one or more levers 31, to one of which the belt-fork rod 32 is coupled. As shown, the guard 15 at the feeding side of the machine is locked, while the guard 14, in consequence of a recessed portion 11 of the disc 8 can be raised to give access to the delivery side of the rollers. On reversal, the disc is turned through approximately half a revolution to look the guard 14 and release the guard 15. When the belt is on the loose pulley, diametrically-opposed notches 9, 10 are in position to allow either guard to be raised. The Specification, as open to inspection under Sect. 91 (3) (a), comprises also a form having a single guard and a lock disc having only one notch. It is also stated that the act of raising either guard when the machine is stopped locks the starting gear. This subject-matter does not appear in the Specification as accepted.

Patent GB-821226-A (GB)
Title: Record sensing device
IPC: G06K7/10
Filed: 1955-09-30
Abstract: 821,226. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 30, 1955 [Oct. 5, 1954], No. 27865/55. Class 106 (1). [Also in Group XL (b)] In record-sensing apparatus, a raster of dashes (or charges of one type) is produced on the end of an electrostatic storage tube, a perforated record is then positioned over the raster and a light beam directed through the perforations. Those dashes which coincide with a perforation in the record are changed to dots (or charges of a different type). As shown, a record 10 comprising separate control sections passes from an idler to a take-up reel (not shown) over the end of an electrostatic storage device 15. On the end of the tube is a raster of dashes produced by deflection circuits 26 and a bit sweep generator 27. When a particular section of the record is aligned with the raster on the end of the tube a control perforation 10 allows light to pass to a photo-cell 18 which, through an amplifier and shaping circuit 33, triggers a flash tube 16. Thus those dashes located beneath a perforation are all illuminated and are changed to dots. Reading is accomplished by traversing the raster with a " dot " pattern thus, if a dot is stored a negative output signal is obtained from a fine mesh screen or transparent conductive coating 29 while if a dash is stored reading destroys the dash and a positive output pulse is developed. In the circuits shown in Fig. 4 the deflection circuits 26 bring the beam to any part of the tube face while blanking circuits cut off the beam between marking periods. Bit sweep generator 27 varies the deflecting potential cyclically so that at each chosen region a dash may be marked. Dot dash generator 28 also controls the turning on and off of the beam so as to increase or decrease the bombardment time to mark either a dash or a dot. The output signals appear on conductive coating 29 and are fed via amplifier 30 and gating and switch circuits 31 to an output which may be connected to a computer. These signals may also control the blanking circuits.
