Title: Improvements in conveyors
IPC: B65G39/20
Filed: 1933-12-14
Abstract: 430,747. Conveyers. EISENWERK WESERHUTTE AKT.-GES., Bad Oeynhausen, Westphalia, Germany. Dec. 14, 1933, Nos. 35233 and 35234. Convention dates, Dec. 15, 1932 and March 15, 1933. [Classes 78 (i) and 104 (ii)] [See also Group XXXII] An extended or continuous train of trucks running around a closed railway is driven by a plurality of stationary power sources disposed along the track at intervals which are such as to keep the push and pull forces between the parts of the train within predetermined limits. Thus along a rising bank, or at places when loads are on the trucks, the power sources will be disposed close together while along a falling bank, or at places where the trucks are empty, the sources will be spaced farther apart. Braking stations may be introduced along the down grades. The power sources may comprise endless chains carrying projections engaging the trucks as they pass by, or may consist of pinions and racks, a series compoundwound electric motor being preferably employed. In order to reduce train friction as much as possible the trucks are each carried by a pair of wheels h mounted on a carriage g pivoted at l to the chassis f of the truck. Each carriage has two parallel arms i engaged by sliding members k on the neighbouring chassis, all the chassis being pivoted together at m. Any divergence of the track from the straight will cause a chassis which has entered on the curve to swing the following wheels h into a position tangential to the curve. The Specification as open to inspection under Sect. 91 comprises also track-shifting means consisting of a longitudinal beam having three vertical and three horizontal rollers, the beam being dragged along by an excavator attached to the middle of the beam by a chain. An endless track having upper and lower pairs of rails may be employed, the trucks being held against both up and down movement by these rails, and returning in an inverted state along a similar four-rail track located beneath. The rails may be attached together by pin-andsocket joints, allowing both lateral and slight upward adjustment between the rail lengths. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to jacquard mechanism
IPC: D03C3/24
Filed: 1929-11-19
Abstract: 339,458. Morton, J. Nov. 19, 1929. Jacquards.-A mechanism for moving a number of (say) thread carriers through different distances comprises sliding members 11 each connected to one of the thread carriers and fitted with a number of stops 12 corresponding to the number of different threads, a like number of vertical rows of horizontal wires 30 for moving the stops 12 into operative position, groups of cardoperated slats 31 notched at the side to receive the flattened parts 30<b> of the wires 30, a reciprocating frame 70 carrying angle bars 35 to move the selected wires 30 and stops 12 horizontally, a vertically reciprocated knife 20 for lifting the members 11 and the thread carriers through different distances as determined by the selected stops 12, and a board 80 which is oscillated to knock all displaced stops 12 back into inoperative position after each operation of the jacquard. As shown, there are four slots 31 in each group and when any selection is lifted slots in all the slats register opposite the flattened part 30b of one or other of the wires 30 in each vertical row, and this wire, which is laterally stressed by a rod 33, springs into the registering slots when the rod 34 of the laterally reciprocated frame 47 allows it to, and brings the end of the wire 30 into the path of one of the bars 35. Half the wires 30 are cranked as shown at 30<c> so as to produce the number of bars 35 that are required. Also half the feeler ends 31<c> of the slats 31 are cranked so that all the slats can be controlled by two rows of holes in the card C. After each lift of the card cylinder 110 it is moved laterally by cam mechanism 100 to bring a new pair of rows of holes in the card into operation, the cylinder only being rotated after several operations.

Title: Snap-action electric push-button switch
IPC: H01H13/60
Filed: 1947-12-31
Abstract: 641,278. Snap-action switches. BOOGAARD, W. Dec. 31, 1947, No. 35333. Convention date, Oct. 8, 1946. [Class 38(v)) The movable contact, or contact-carrying member of a push-button switch comprises a U-shaped member 3 having its limbs astride an insulating guide 2 and provided on its centre portion with recesses 12, 13 which are alternately engaged by the pushbutton 1, slidable in the guide 2, under the action of springs 4 situated on either side of the contact 3 and connected between it and a fixed plate 17. On pressing the button 1 the contact 3 is lifted, from the position shown in full lines in Fig. 1, until projections 11 clear a cam surface 16 thus permitting the contact to pivot about the recess 12 and come to rest with the projections 11 against central cam surfaces 14. During this movement the projections 11 break the circuit between contacts 8 and further projections 10 bridge contacts 6. On release of the button, the contact 3 pivots about the projections 11 and the projections 10 slide through the contacts 6, thereby clearing them, and come to rest on the plate 17 beyond a further cam surface 15; also, the other recess 13 moves into engagement with the push-button, the further actuation of which restores the switch to its initial condition. In a modification, the member 3 is of insulating material having conducting projections 10 which bridge the contacts 6 to form a simple switch.

Title: Optical device
IPC: G02B17/00
Filed: 1965-08-18
Abstract: 1,103,249. Optical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 18, 1965 [Dec. 17, 1964], No. 35380/65. Heading G2J. Optical apparatus comprising a plurality of mirrors arranged to form multiple images on each mirror of an object by multiple reflections therebetween, is provided with means for reintroducing an emerging image to the system of mirrors to form further different multiple images on the mirrors by multiple reflections therebetween. In the embodiment of Fig. 1, two spherical concave mirrors 4, 6 of equal radius are arranged side by side to reflect alternately an image on to a third spherical, concave mirror 2 of the same radius. The centre of curvature of the mirror 2 lies between the mirrors 4, 6 while the centres of curvature of mirrors 4, 6 lie on the mirror 2. A light-source 8 is imaged adjacent the mirror 2 and this image is reflected by the mirror 4 to form an image on the mirror 2. Further alternate reflections occur at the mirrors 4, 6 after each reflection at the mirror 2 until an image is produced by the mirror 6 outside the area of the mirror 2. This image is arranged to coincide with a selected part of a character mask 32 on adjustment of either or both mirrors 4, 6. The means for reinserting the emerging image into the mirror system comprises a field lens 38 and a spherical mirror 40 which produce a real image of the selected character of the mask 32 adjacent the mirror 2. It follows that, after further multiple reflections between the mirrors, a second emerging image is formed adjacent the mirror 2, the position of which is independent of the position, of the character chosen on the mask 32. The character selection may be effected by means of an electro-optical deflector in combination with a flat mirror and an associated lens which replace one of the mirrors 4, 6.

Title: New or improved machine for plucking birds
IPC: A22C21/02
Filed: 1927-12-31
Abstract: 309,004. Bingham, G. C. Dec. 31, 1927. Poultry, dressing. - A machine for plucking poultry comprises a num ber of spaced discs on a common axis, adapted to be rotated and deflected so that their periphera edges are caused, one or more times during eacl revolution, to meet at a predetermined point, to grip the feathers, and then to recede to release them after they arc plucked. As shown ir Fig. 1, three discs C are mounted on a shaft B, the outer discs being supported thereon by universal joints. The outer faces of the outer discs have cam projections thereon, which are engaged adjacent to a screen covered opening a in the casing A by spring- pressed rollers E and rigid rollers D. The cam projections are first engaged by the spring rollers E and then by the rigid rollers D, the peripheries of the discs being held together until the cam projections are released from the rollers D, the peripheries then receding until another set of cams are engaged with the rollers. The feathers are gripped between the discs and pulled over the bottom of opening a which acts as a plucking bar. An air blast may be directed on the meeting point of the discs to ruffle up small feathers. The feathers are sucked away by a rotary fan F which discharges them into a bag. The fan F is driven from a motor and the plucking discs are driven by a belt from the fan. In a modified form, the apparatus is held in the hand and passed over the bird to be plucked. The shaft B is driven through bevels and a flexible drive, and the casing has a hollow extension which is held in the hand and is connected by flexible tubing to a suction fan. The cams or the discs C are replaced by spring buffers, e.g. of rubber. In another modification, the discs C are replaced by a broad flexible helix, the convolutions of which are deflected in the same way as the discs. Alternatively, flexible discs may be rigidly mounted on the shaft B and deflected bv cams and rollers. According to the Provisional Specification, the universal coupling for the discs may comprise serrated blocks on which the discs are loosely mounted, the holes through the discs being correspondingly serrated.

Title: Improvements in and relating to apparatus for simulating underwater craft
IPC: G01S7/40
Filed: 1961-10-05
Abstract: 963,925. Signals from submerged vessels. CLEVITE CORPORATION. Oct. 5, 1961 [Jan. 23, 1961], No. 35875/61. Heading G4F. [Also in Divisions B7, G3, H2 and H4] A submarine simulator (see Divisions B7, G3, H2, H4) can perform typical submarine manoeuvres and can receive and transmit sonar pulse tracks as if an actual submarine were passing through the sonar beam. The length of the echo is controlled so that it will seem to have emanated from the bow beam or quarter depending on bearing. The simulator has a bow transducer 34 and aft transducer 54, spaced apart by approximately one half of the centre frequency of the system. An incoming sonar ping can be received at 34, amplified at 88 and 90 before being applied to the input of a recording head 92 to be recorded on a magnetic wheel 94. The signal is reproduced at the loose playback head 96, amplified at 98 and 100 and applied to the aft transducer 54 to be sent back to the sonar operator. A signal received at the bow or stern aspects will arrive at the transducers 34 and 54 at different times. A sonar ping first received at 54 is amplified at 104 and used to start trigger circuit 106 to be amplified to the playback head 96 to terminate the action of the elongator circuit thus producing a signal which is dependent upon the time delay between the two hydrophones 34 and 54. The simulator can also provide a signal for remote location by D.F. equipment by a transmitter 52 which produces a signal when the simulator is on the surface. A radio receiver 50 starts the simulator on its manoeuvres. An electronic simulating mechanism is provided to develop characteristic noises of different types of submarines. A magnetostrictive transducer 44 is cast into the hull to convert the noises into underwater sound signals. Reference has been directed by the Comptroller to Specification 839,102.
