Title: Loom shuttle - with a seat for retaining a support spindle of a weft yarn package
Inventor: LANGENHOFF HUBERT
IPC: D03J5/00
Filed: 1973-04-07
Abstract: A loom shuttle is formed in two parts and includes a cavity in which a weft yarn package is carried and a seat at the end of the cavity in which a foot of the support spindle of the package is retained. A slot connects with the seat to allow the two parts of the shuttle to be separated whereby the spindle foot can be located in the seat, and a resilient fixing plate is located in a transverse aperture in the shuttle in the region of the slot to prevent subsequent relative movement between the two parts. The fixing plate lies in the median plane of the shuttle, and one end has a thickened flange which locates in a recess in the aperture whilst the other end is apertured to receive a retaining pin which passes through the shuttle. The arrangement is simple and allows rapid replacement of the weft yarn package.

Title: Roadway gutter block - gutter forming and cover stones combined in load-bearing element
Inventor: RINN HELMUT
IPC: E01C11/22
Filed: 1973-08-31
Abstract: For incorporation in motorways, roads, town squares and elsewhere, the structural element consists of two stone blocks, one forming the gutter, the other covering the gutter, both fitting together so as to form a unit capable of bearing loads in the carriageway.

Title: Matrix with receiving switches with uncoupling diodes - has number of operated line leads and current paths continuously monitored
Inventor: HAUG FRIEDRICH
IPC: G06F11/22
Filed: 1973-09-28
Abstract: The continuous monitoring method is for the operation of a matrix-type switching circuit, particularly as used in telephone communications installations, so as to recognise and localise faults. The receiving switches with their uncoupling diodes on the input side are arranged at line and column lead junctions. Test voltages are applied through individual resistances to the line leads and column leads, these resistances loading all the uncoupling diodes. The resistances are connected to a common measuring point to which a further resistance is joined. Its second terminal is connected to the potential of the test voltage source. The measuring point is connected to one or more voltage comparators so that the whole resistance arrangement forms a branched voltage divider.

Title: Digital position measuring system - with synchro resolver which utilises a digitised reference operating with a counter control system to provide angular position control
Inventor: WOLFGARTEN WALTER
IPC: G05D3/12
Filed: 1973-09-29
Abstract: An inductive position measurement system uses a sender synchro and a receiver synchro that have electrically coupled stator windings. The rotor of the sender synchro is coupled to a standard AC voltage generator. Depending upon the angular reference value, three measured voltages in the stator connections will result in an error voltage being generated. Comparison of the phase of the standard voltage with the error voltage in a comparator circuit results in an analogue error signal. Three discriminator circuits consisting of amplifiers and relays allow the three phase displaced signals from the stator windings to be digitised. The digitised reference is used to set counter circuits operating at a rate related to the standard input voltage frequency.

Title: Radio receiver tuning cct. - uses amplitude limiter for receiver demodulated signal, subtraction stage and integrator
Inventor: BURGER ERICH
IPC: H03J3/14
Filed: 1974-03-25
Abstract: The demodulated signal generated by the receiver, is applied to an amplitude limiter, and the demodulated and the limited signals are applied to a subtraction stage delivering their difference which is applied to an integrator whose output signal is applied to a display unit showing the integrated signal amplitude.
