Title: Rotation control device for sync motor permanent magnet rotor - prevents permanent rotor rotation in wrong direction by field plate arrangement
Inventor: ERWIN ROBERT DALE
IPC: H02K7/118
Filed: 1974-05-06
Abstract: A pinion (50) is mounted to rotate about the rotor (16). The rotor carries a stop (68), and a wedge arrangement (70) is used for releasable connection of the pinion to the rotor. In this connection the pinion has a preset rotary freedom in relation to the rotor. The pinion meshes with a drive gear (54) which carries an engagement element (72) for resting against the stop if the rotor rotates in wrong direction. The drive gear has a channel (82), spaced from the engagement element, through which the stop can move without hindrance when the rotor rotates in correct direction. Preferably the stop is in the form of a pin (74), protruding from the rotor surface. The engagement element may be formed by a lug protruding from the drive gear surface.

Title: Heat exchanger with finned pipe clusters - has stabilising corrugated pipe spacers and pipe cluster straps
Inventor: ARTEMOW LEW NIKOLAEWITSCH
IPC: F28F9/013
Filed: 1974-05-08
Abstract: Each unit consists of a number of tubes whose ends are connected to the upper and lower collector chamber. The pipes have longitudinal ribs and are held by folded strips so that a hexagonal unit is formed. The pipe separating strips also form hexagonal channels in the pipe cluster with parallel pipes. Uniform spacing of pipes improves heat transfer and each unit can be readily replaced. The corrugated spacing strips are arranged to form hexagonal cells in the regions where the pipes (14) have no ribs. The hexagonal cluster is held firmly together by strips (25). The pipe clusters are connected by their end chambers to the inlet and outlet manifolds for the fluid which is passed into the pipes. The other fluid is passed through the housing.

Title: Terminal strip built up from individual connector units - with spring for providing pressure between contacts uses several individual insulated bodies
Inventor: SCHMIDT GUENTER
IPC: H01R9/24
Filed: 1974-07-16
Abstract: The connector is primarily intended for use in light current applications, for example telecommunications equipment. Individual insulated bodies (1) have laterally projecting upper and lower terminals (7, 9). The connectors may be used for wire connections but are more particularly intended for holding fuse elements or voltage surge diverters (6). A spring (13) acts on the lower terminal to provide constant contact pressure between the electrical parts. Each connector is provided with a foot at one end and a slot (3) in the base at the other. A row or required number of terminals can thus be assembled by sliding foot into adjacent slot. Fixing is through the free foot and a keep or key in the otherwise unused slot at the other end of the row.

Title: Contactless torque measuring device - has elastic coupling component between driving and driven shafts
Inventor: LUTZ HANS
IPC: G01L3/10
Filed: 1974-07-25
Abstract: Both shafts have marks which, when moving past pulse pick-ups, generate electric signals whose spacing in time is a measure for the torque. The pulse pick-ups (5, 7) are mounted on a common support (8), swivelling about the shaft axes. The support (8) is connected to a bracket (9) rotatable about the shaft axes. Pulse pick-ups are movable relatively to each other. The zero setting of the impulse generators (5, 7) can also be tested. If a signal appears in the evaluation circuit at no revolutions setting the generator (5) can be moved along the groove (11) so that the difference in time between the output signals by a turning of the support (8) is equal to nought.

Title: Cooling water prestressed reinforced concrete pipe - comprising half-shells with peripheral stress members prestressed by internal fluid pressure
Inventor: HERTEL WILHELM DIPL ING
IPC: F16L9/22
Filed: 1975-02-26
Abstract: The large pipe is of the type used to convey cooling water in power-station installations, or for similar purposes, usually involve high expense and considerable transport difficulties, and is here in the form of a reinforced-concrete pipe pre-stressed by medium internal pressure. This is made up from half-shells, of half ultimate wall thickness, made in lengths depending on the capacity of the hoisting appliances in use, and provided with internal and external reinforcement for transport and for accommodation of forces and moments occuring when the duct is filled. Pre-stressing of the stress members round the curved half-shells is effected by means of an internal pipe pressure with a fluid. Pre-stressing may also be carried out without internal pressure, with hydraulic presses, pref. built into the gaps.

Title: External ring on large diameter tube - has keyways machined in ring with wedged internal keys
IPC: F16C13/04
Filed: 1975-03-19
Abstract: The external ring or flange (2) is attached to a large diameter tube (1) by means of radial key and keyways (11, 20). To avoid large-scale welding on the tube (1) in order to produce keyways, the tube section concerned (10) is made from thicker plate material than the rest of the tube. Either prior to or after bending into a ring-shaped tube section, the required keyways are machined on the outside of the ring (11). The matching internal keys of the ring (2) are then locked in position on assembly by means of wedges and axially fixed by end bars. The only welding required by this method is the radial joints between the ring section (10) and the remainder of the tube (1).

Title: Plywood elastic strip forming - has laminations pressed in multi-cavity tool to ensure greater thickness of edges
Inventor: WERZ JAKOB FRIEDRICH
IPC: A47C23/06
Filed: 1975-07-07
Abstract: The laminated wood strip for mattress backing exhibits an enhanced stiffness achieved by hot pressing veneer sheets whose fibres run in the longitudinal direction of the produced strip. The design achieves a greater stiffness compared with conventionally manufactured strips for the same amount of wood used in the unit. A lesser number of strips may ensure the mattress the same characteristics as with normally used strips.

Title: Internal shoe drum brake with wear adjustment - has turnbuckle connected between shoes and operated by ratchet when brake applied
Inventor: SCHROETER HANS O
IPC: F16D65/56
Filed: 1975-11-13
Abstract: Internal shoe drum brake has a wear adjustment comprising a turnbuckle connected between the ends of the shoes opposite the brake operating mechanism. The opposite hand screws of the turnbuckle are pivoted to the respective brake shoes (26). A ratchet wheel (2) secured to the nut of the turnbuckle cooperates with a pawl (8) mounted on the nut and ratchet wheel assembly. When the brake is applied the shoes participate by a small amount in the rotation of the drum. This movement slides the pawl up a ramp secured to the brake support plate and so causes the turnbuckle to take up wear.
