Title: Fur bands in sharp contrast, for garment manufacture - whole skins such as mink, pieced with strips cut diagonally
Inventor: SCHACHTMEYER MARTIN V
IPC: C14B15/10
Filed: 1973-07-12
Abstract: Garment sections for furs are built up from animal pelts stretched to shape, with diagonally cut strips added, or half sections are joined together to form the vertical bands from which the garment is assembled. The base component of the half section is made up from a series of strips cut parallel to the centre line of the skin, or from a parallelogram with two long sides running obliquely to the pelt centre line, cut so as to make two triangles and a number of strips. The strips or rectangular pieces are assembled so that the pelt centre line and/or the pelt edge zones lie obliquely to the long axis of the half section base component, at an angle sufficient to give the necessary width. Both ends of the half section base component are formed by the centre line of the skin, or one end may be formed by the pelt centre line and the other by the pelt edge, and vice versa, whilst the sides of the half section base component are formed by zones of the pelt(s) at right angles to the centre line of the original pelt(s). The triangles left open at the ends of the base components are filled in with triangles of fur colled from other skins or parts thereof. The strips are so formed that matching points are easily found when piecing up. All skins need not be cut into strips but whole skins can be pieced together reducing labour and waste of material due to less cutting and sewing. Skins can be manufactured with sharply contrasting patterns, colours and markings.

Title: Signal transmission monitoring system - for checking that simultaneous transmission over single link cannot occur uses binary words
Inventor: KEICHER WOLFGANG
IPC: G06F11/08
Filed: 1973-07-26
Abstract: The monitoring system ensures that simultaneous transmission of communication signals, due to an insufficient number of transmission links cannot occur. When a subscriber initiates a call, and therefore requires access to a link, a binary word describing the initiating station is set up. The individual words originating from several stations are gated together using an 'OR' gate. When the output at the 'OR' gate shows a 'completed' signal, equivalent to all links in use, the monitoring alarm is given, and reception of garbled messages may be prevented.
