Patent DE-2550153-A1 (DE)
Title: Motor speed controller - has phase locked feed-back loop with poles and zero settings in real frequency range
Inventor: LEE MARTIN DAVID
IPC: H02P23/00
Filed: 1975-11-07
Abstract: The frequency range begins at the zero corresponding to d.c., and rises to the value of a reference. The motor has an integral pole with a value equal to the zero of the real frequency range, and a mechanical pole with a value close, but not equal to, the zero of the real frequency range. A comparator compares the phase of a signal derived from the rotation with that of a signal of the reference frequency. It delivers an error signal when the phases differ. A filtes responds to this signal and delivers a phase correction signal. The filter has a characteristic pole whose value is close, or equal, to the zero of the frequency range. At least two characteristic zeroes are provided.

Title: Plug connection for flexible plastic hose - uses compressible clamp sleeve inside screw fitting with lugs to bite onto hose
Inventor: REUBELT ROLF DIETER ING GRAD
IPC: F16L33/32
Filed: 1976-03-17
Abstract: A plug connection for plastic hoses has clamp sleeve (8) which plugs into a screw nipple (1). The clamp sleeve (8) which is made from a hard elastic material, has two diametrically opposite lugs (16). The lugs are partially separated from the sleeve body so that they can be compressed radially. With the hose end located inside the clamp sleeve (8), the sleeve is plugged into the screw fitting (1). External shoulders (17) on the radial lugs (16) are engaged inside an internal location groove (2) on the screw fitting. The lugs are thus compressed so that the hose inside is firmly held in its location.

Title: High water protection for coastal bays - has dam with long narrow canal allowing passage of ships and restricting tidal flow
Inventor: POHL LOUIS
IPC: E02B3/02
Filed: 1976-06-29
Abstract: The protection system against high water for bays or river mouths has a dam for separating the bay from the open sea. This dam has channel allowing passage of ships. This system protects the areas and ports against high water and ensures continuous unobstructed traffic between the port and the sea. The system includes a canal for connecting the bay and the open sea, the canal being always open. This canal has much narrower width than that of the river in the mouth area. The main part of the canal is situated in front of the coastline and it extends into the open sea. The main part of the canal is situated behind the dam. The canal is so long that the flow time of the large wave in the canal is comparable with the tidal periods.
Patent DE-2630481-A1 (DE)
Inventor: WUTHRICH PAUL
IPC: G04B3/04
Filed: 1976-07-07
Abstract: A three position detent arrangement for facilitating axial positioning of the rotatable stem of a wristwatch in order to enable the wearer to locate the proper axial position. Frusto-conical surfaces of selectively different included angles are employed to provide steep and shallow slopes for the detent spring, so that the steeper slopes require relatively higher force to move from the intermediate position to either end position. This enables the operator to locate any of the three positions with assurance.

Title: Double wall storage tank - with spacer layer of uniform thickness between inner and outer shell
IPC: B65D90/501
Filed: 1976-12-22
Abstract: A double-wall tank, made of glass-fibre reinforced plastics, e.g. for storing fuel oil, diesel fuel or petrol, maintains a uniform distance between inner and outer wall. A gas or liquid permeable spacer layer of uniform thickness is joined to the outside of the inner wall and the walls of the outer tank are applied directly to it. Both inner and outer tank share the static load so that the inner tank need not be made extra strong. No separate cores are required to mould the two tanks so that the total mfg. costs are much lower. A leakage warning system can be easily added.

Title: Practice aid for table tennis player - has vertical panel located at one end of table to rebound ball across net
Inventor: BALSIES HARTMUT
IPC: A63B69/00
Filed: 1977-04-20
Abstract: A vertical panel (11), located at one end of a table tennis table (1) returns the tennis ball similarly to a playing partner. It is thus possible to practise the game without the help of an opponent at the opposite end of the table. The panel is mounted on a vertical stand (6) which allows it to pivot about a vertical axis (7). The mounting brackets (12) which attach the panel to the swivel head (9) of the vertical stand, include two horizontal pivot shafts. Thus the incline of the panel can also be changed in order to vary the path of the rebounded ball.

Title: Prodn. of fluorescent tube in bent configuration - heats straight lamp tube and bends its ends in parallel towards tube centre
Inventor: KAWAMURA OSAMU
IPC: H01J61/32
Filed: 1977-05-31
Abstract: The process concerns a fluorescent lamp of special geometric shape. The production starts with a straight lamp tube which is heated and its opposite ends are held in a parallel bending device, until they reach a position over the middle part of the tube. The bent tube is evacuated and then filled with ionisable gas. After proper sealing the tube ends are capped. During bending of the tube one end is kept stationary, while the other end is bent through 250 deg. to come as near as possible to the stationary end. The caps on the tube ends may be in one piece or separate. If a common cap is used, it is formed by an elongated housing with two apertures at one side for retaining the tube ends, while its other side has a recess for the terminal pins.
