Patent DE-2710528-A1 (DE)
Title: Audible indicator on equipment alarm panel - has horn energised via relay whose coil is in series with transistor
Inventor: GMEINDER GEORG DIPL ING
IPC: G08B23/00
Filed: 1977-03-10
Abstract: The modification to the multichannel alarm panel eliminates the need for a separate supply for the horn relay. The horn relay coil is in series with a transistor whose base is connected to a voltage divider between a negative and auxiliary negative rail. When the alarm contact closes a small current flows through the main alarm relay, the auxiliary negative rail, and the potential divider. The transistor switches due to the change in base bias and the horn relay is energised. Its contacts energise the horn and connect the negative rails together. The main alarm relay can now pick up, and the circuit functions in the established manner.
Patent DE-2728464-A1 (DE)
Inventor: ERIKSSON GEORG TORD
IPC: C11D11/00
Filed: 1977-06-24
Abstract: Process for protecting and cleaning surfaces which are subject to soiling with hydrophobic substances, a protective layer removable by means of water being applied to the surfaces before the soiling and, after the soiling, being removed together with the dirt by washing off with water which may contain detergent additives and/or alkali. The process is suitable in particular for the pretreatment of automobiles for undersealing and cavity sealing, since it makes possible simple removal of the splashes of rust preventing agent which have occurred on the painted exterior bodywork parts and on the windows.

Title: Sports shoe or football boot sole support - using resilient portion curved transversely to longitudinal direction of sole into dish shape
Inventor: DASSLER ADOLF
IPC: A43B5/02
Filed: 1977-07-18
Abstract: At least one of the parts of the shoe or boot base(1) i.e. the outer sole(2) welt(3) or if necessary a reinforcement insert layer consists at least in the area of the forward sole of a resiliently elastic material which is curved downwards in dished manner across the longitudinal direction of the sole. Either the entire shoe base or a part in the front sole is provided with a transverse curvature(7) which clearly extends beyond the transverse curvature previously formed by a certain rounding of the last. The height of this arched curvature measured opposite the edges of the corresponding part is pref. 3 to 4 mm or more. A convex downwardly facing curvature of the dished part made of a deformable material does not prevent this part from bending upwards but has a strong reinforcement effect downwards which only allows bending downwards when the curvature springs in.

Title: Common frequency radio communications network - has numerous overlapping transmitter zones and selection unit actuating groups of transmitters with non-overlapping zones sequentially
Inventor: GORZEL HERIBERT DIPL ING
IPC: H04B7/24
Filed: 1977-09-02
Abstract: The radio communications network has a large number of transmitters all operating on the same frequency and covering overlapping zones. When making a general call to a subscriber who may be anywhere in the area, i.e. anywhere in several zones, only non-overlapping transmitters are actuated simultaneously. Groups of transmitters are actuated sequentially. This avoids the interference that would otherwise arise in the overlapping parts of the zones. The transmitters are connected by 2-wire cables to a control centre.

Patent DE-2811987-A1 (DE)
Inventor: BECKEL CHRISTIAN DIPL ING
IPC: D03J1/14
Filed: 1978-03-18
Abstract: The thread-monitoring device in the form of a mechanical sensor (4), which is connected operatively to a microswitch (12), is provided for monitoring the position of individual threads, especially in a drop-wire machine, and is suitable for putting the machine out of operation in the event of faults. The sensor (4) is arranged on an axis (8) jointly with a guide piece (15) and is operatively connected to the latter. The guide piece (15) is moved on the axis (8) according to the work cycle of the machine by means of a gear. The sensor (4) and the guide piece (15) are equipped with monitoring cams (16; 23) which are sensed alternately, in dependence on the working movement of the guide piece (15) and on the quality of the thread-transport movement, by a switching lever (11) of a microswitch (12) which is capable of initiating corresponding switching functions. The monitoring device serves for increasing the operating reliability of the drop-wire machine, especially when it is used on warps of high fineness and high thread counts. <IMAGE>

Title: Improving the installation properties of asphalt - under wet conditions, by incorporating silica xerogel
Inventor: BIENERT HEINZ J
IPC: E01C7/18
Filed: 1978-03-23
Abstract: The installation properties of pouring asphalt and asphalt mastics under damp and wet conditions, esp. in roadmaking, are improved by incorporating silica xerogel into the mix before installation. In place of silica xergels, thermally expanded granules, esp. of acidic rocks, having properties resembling those of silica xerogel and with hydrophilic behaviour, can also be used. The xerogels generally contain up to >90% SiO2 and have a pore volume of 80-90% and a surface of up to 800 m2/g. Generally nearly equal 0.10% of the xerogel is incorporated into the bitumen during mixing. The addn. of the xerogel reduces the sensitivity of the asphalt to installation under wet conditions, e.g. road marking under rainy conditions and overcomes the formation of voids, craters and channels in the laid asphalt without affecting the penetration of flexibility.

Title: Sea-belt retractor assembly - has control mechanism changing torque on spool depending on whether belt is in use or is taken off
Inventor: SHIMOGAWA TOSHIAKI
IPC: B60R22/44
Filed: 1978-05-26
Abstract: The design proposes a retractor assembly which acts on the seat-belt spool with a varying amount of torque depending on whether the belt is in use or whether it is taken off. The mechanism consists of a frame (1) in which a shaft (2) is fitted for the oncoiling of the seat-belt (4). The mechanism is fitted with a spring assembly consisting of a spring (8) with its end (8a) anchored on the frame and a further spring (6) with its end (6c) connected with the shaft. The two springs are arranged in series. The mechanism is fitted with a control device controlling the amount of torque acting onto the shaft according to the functional state of the seat-belt. The control device comprises a ratchet wheel (7) seated rotatingly on the shaft (2) accommodating the ends (8b, 6a) of springs (8) and (6) further catch (13) which selectively engages with one of the teeth on ratchet wheel (7) and causes the spring assembly to act with a reduced torque on the shaft.

Title: Panoramic respirator mask window frame - has suction grooves or cups on inner contact surfaces
Inventor: GOERNER WALTER DIPL PHYS
IPC: A62B18/08
Filed: 1978-05-29
Abstract: The respirator mask window assembly has marked curving. Its purpose is to ensure a tight fit of the window in its frame without additional stiffening devices. The face mask body has a moulded-on elastic bead of U-cross section accommodating the thickness of window sheet. The inner surfaces of the U-shape are provided with a continuous groove, which produces a suction action on the sheet when it is fitted. Alternatively the sucking action can be produced by suction cups evenly distributed along the inner surfaces of the bead. The frame with its U-cross section envelopes from the outside the bead and provides hermetic seal between window sheet and mask as well as additional stiffening.
