Patent DE-2602861-A1 (DE)
Title: Continuous moulding machine for wet plaster - has plaster feed and levelling roller above conveyor feeding cutter and discharge
Inventor: ALQUEZAR GAZULLA MANUEL
IPC: B28B11/08
Filed: 1976-01-27
Abstract: The machine produces sheets continuously from a prepared wet plastic mixture and constitutes an endless belt (1) of transverse 'U' section, with a plaster (4) discharge chute (3) above the front end of the belt. A transverse idling roller (5) close to the chute (3) and bearing tangentially on the edges of the belt (1) levels the advancing plaster. The belt surface receiving the plaster can be set in relief to desired patterns and transferse diaphragms can be employed to effect longitudinal sectioning of the plaster on the belt. The plaster sections are then received by discharge rollers.
Patent DE-2605065-A1 (DE)
Title: Flame cutting steel using reheating burner to prevent hardening - where reheating burner has lower flame temp. than cutting burner
Inventor: GREIFZU KARLHEINZ
IPC: B23K7/00
Filed: 1976-02-10
Abstract: Hardening is avoided during and immediately after the flame cutting of steel plate or sheet, by using a reheating burner which follows the flame cutting burner. The reheating burner is driven by a combustible gas mixt. and compressed air. The compressed air pref. forms max 90 vol. % of the total of air plus gas mixt.; and the gas mixt. consists of acetylene, propane, natural gas or other gas mixt. The reheating burner is pref. a preheating burner with either a large no. of gas jets or a single gas jet. The cooling rate after flame cutting is retarded to prevent hardening of the cut edges and the steel in the vicinity of the cut edges; such hardening interferes with subsequent working or machining operations. For example, if steel sheet is to be zinc coated or lacquered it must first be shot-blasted to ensure good adhesion of the coating; but hardened steel is difficult to shot-blast so good adhesion is not obtd.

Title: TDM access satellite communication system - avoids burst control by transmitting frame synchronising signals outside frames formed by station
Inventor: HAEBERLE HEINZ DR ING
IPC: H04B7/212
Filed: 1976-04-08
Abstract: The time division multiple access (TDMA) satellite communications system avoids burst phase control by transmitting the frame synchronisation signal outside the TDMA frames formed by the stations. One station transmits the frame synchronisation signal outside the frequency band in which the stations transmit their bursts. All stations have means of receiving and evaluating the frame synchronisation. Alternatively, one station may transmit the frame signal in coded form within the TDMA frame but with a level so reduced that it causes no interference.

Title: Carton pack with swing lid and handle - handle tab doubled back, finger holed, glued to top for tear-off release
IPC: B65D5/54
Filed: 1976-04-30
Abstract: Carton pack is made up from a folded cutout with a tear-open lid swinging up from one side top rim and a handle formed from pieces of the cutout. The handle (5) forms a continuation of the sidewall (8) which has the lid axis running along its top rim. The handle consists of a tab (9, 9') doubled back to the top rim to form a double-walled piece with finger hole (7, 7') and with an end piece (11) attached to the end of the tab and glued to the top of the carton. Before use, the tab is holed down onto the end piece and glued to this by side tongues (12, 12') so that the handle is thus held down level with the carton top. In use however, the handle tears free along lines (6, 6') so as to present itself for upright carrying etc.

Title: Cable entry for aluminium sheathed cable - is shaped to fit cable sheath and provides mechanically formed seal and earth continuity connection
Inventor: HASELHORST HANS DIPL ING
IPC: H02G3/06
Filed: 1976-04-30
Abstract: The cable jointing box (1) is provided with an entry duct or neck (2) which is designed to suit the particular cable (3) being used. A mechanical clamp or lock is incorporated which seals the entry against the ingress of moisture and also gives electrical continuity between the aluminum cable sheath (4) and the jointing box (1). In the case of a large diameter cable with a corrugated sheath the entry duct (2) is in the form of a threaded hole of form and pitch matching that of the cable sheath. The cable can therefore be screwed in tightly to achieve the desired objectives. Alternatively, on a small diameter cable with a smooth sheath, the clamp can take the form of a tapered bush fitting in a tapered entry with a concentric screwed plug at the outer end to tighten the bush against the entry and cable.

Title: Spot welding small contacts onto metal strip
Inventor: ROSENSTOCK BERNHARD
IPC: B23K11/20
Filed: 1976-09-18
Abstract: Machine for the automatic resistance welding of a metal electric contact plate (a), with max. dimension 3 mm, pref. 1 mm, onto prescribed zones on a carrier strip (b), which has perforations so it can be fed stepwise between two welding electrodes. Metal contact strip (a) is fed onto the top of a drum, where a punch stamps a plate (a), and the drum rotates on a horizontal axis to carry a circular row of plates through 180 degrees so they meet strip (b). The electrodes then apply pressure to make the weld. The drum has a row of bushes on its periphery, which receive the stamped plates; and one electrode can move vertically inside the drum. Two or more rows of bushes may be fitted on the drum, each bush having a conical inlet for a counter punch driven vertically during the stamping operation. Process is for spot welding noble metal or other contacts (a) onto a spring- or magnetic- carrier strip in mfg. relays, reed relays; or for use in mfg. integrated circuits. Conventional machines and methods achieve 100-130 spot welds/minute. The invention provides 600 welds/minute.

Title: Rucksack made from child's apron - has bottom made from upper part, and remainder tightened by cord through decorative buttonholes
Inventor: RENTSCHLER GEB RENTSCHLER FRID
IPC: A41D15/04
Filed: 1977-04-29
Abstract: The apron for a child is transformed into a rucksack by threading a cord through the buttonholes and using the upper chest piece as the bottom of the rucksack and the tie ends (34, 38) as carriers when the rucksack is carried on the back. The chest piece (11) has a button at the upper left corner (12) and another in the opposite corner (13) on the outside of the apron. Its sides (14, 16, 17) are all straight but running towards one another at the bottom. This makes the lower edge (18) slightly narrower where it is sewn to the lower part of the apron (19).

Title: Editor for narrow gauge sound cine film - has sound heads offset on pivoted yoke by amounts equal to sound to vision displacement
Inventor: SCHLIEBEN ULRICH VON
IPC: G03D15/04
Filed: 1977-05-18
Abstract: The editor for the sound-cine narrow gauge film has a sound head comprising a yoke pivoted in the middle and with separate sound heads at the ends. The heads are spaced by the same amt. as the separation of the sound and vision while the yoke mounting ensures that both heads remain in contact with the film at all times.

Title: Telephone subscriber's line testing system - has auxiliary contact enabling subscriber's loop to be reproduced through exchange equipment for tracing fault
Inventor: OBERHAUSER WALTER DIPL ING
IPC: H04Q3/42
Filed: 1977-06-10
