Patent DE-4125442-A1 (DE)
Inventor: JAAP REINHARD
IPC: E04F21/165
Filed: 1991-07-31
Abstract: It is common practice to point visible brickwork manually, i.e. using a mortar-board and pointing trowel. When plastic mortar, i.e. mortar with a high water content, is used, mechanical devices are known. In the case of faced brickwork using the dry process, in particular, however, damp mortar, having a very low water content, is used to prevent bloom on the bricks. No mechanical devices have so far been known for this process. This problem is solved by the invention in that the damp mortar is introduced  by means of vibration into the joints from a hopper-like container (11) and compacted there by means of the same vibration. A device for implementing this process is proposed in which the necessary transport path is kept as short as possible. The invention is applicable in the building industry and in the manual building trade.
Patent DE-4126594-A1 (DE)
Inventor: TASKAS ALEXANDROS
IPC: B29C45/17
Filed: 1991-08-12
Abstract: A process for the production of elastic parts from a rubber-like material, which, as an unvulcanised material, is injected via at least one nozzle with the aid of a piston into a mould, in which the material is vulcanised, the feed channel and the nozzle being cleaned by ejection before each fresh injection operation. The process is distinguished by the fact that the ejection of the partially vulcanised material from the nozzle and the feed channel is carried out in a controlled manner, preferably with the aid of a computer, by moving the piston, which presses the rubber material into the mould, forward by a predetermined distance, this distance just being sufficient to build up the pressure in the barrel so that material is only ejected from the nozzle and the feed channel, and no or only little further rubber-like material flows through the nozzle and feed channel and is lost. <IMAGE>

Title: Treatment of incinerator airborne ash and dust - comprises sepg. into coarse and fine fractions and removing heavy metals
Inventor: KUGLER KURT
IPC: F23G5/14
Filed: 1991-10-02
Abstract: In a process and assembly to collect airborne dust and ash from municipal incinerators, the dust contg. heavy metals is sepd. into a coarse fraction and contg. a small quantity of heavy metals and a fine fraction contg. a large quantity of heavy metals. The fraction contg. a small quantity of heavy metals is returned to the incinerator where it is incinerated without any requirement for further treatment as special waste; that the fraction contg. a high concn. of heavy metals is treated in a process for the recovery of heavy metals. The sepn. of the fine fraction contg. a small quantity of heavy metals is in the range of 10 microns. The coarse fraction is pref. reduced in size by further incineration which destroys dioxin and evaporates the residual heavy metals. The fine fraction with a high concn. of heavy metals is then dealt with by a recycling process. USE/ADVANTAGE - The process reduces the vol. of dust requiring special treatment for the collection and disposal of heavy metals. The consequence is reduced energy consumption and fewer harmful emissions.

Title: Detecting reverse motion of motor vehicle for brake control system - measuring yaw rate, vehicle speed, wheel state and steering angle and using given equations to derive forward or reverse motion signals
Inventor: VAN ZANTEN ANTON DR
IPC: G01P13/04
Filed: 1992-07-16
Abstract: The yaw rate of the vehicle is measured and a modelled yaw angle (wm) derived from the steering angle ( delta ), vehicle speed (VF) and wheel radius (R). The yaw angle and various constants are used with a given equation to derive a time dependent parameter. A forward motion signal (LV) is generated when the parameter exceeds a threshold and/or the measured speed exceeds the maximum reversing speed. A reversing motion signal (LR) is generated when there is no forward motion signal and the parameter is less then a second threshold. The reversing signal is suppressed when the forward motion signal is present. USE/ADVANTAGE - For use in brake control systems with different characteristics for forward and reverse motion. Reliable detection of reverse motion is achieved at low cost using min. number of sensors.

Title: Gauging-stop for bevelling strip material to constant dimension - has horizontally moving arm guided by slide-rail and carrying gauge probe profiled to bevel to enable use of calibrated scale
Inventor: ACHERMANN HANS
IPC: B23Q16/00
Filed: 1992-07-28
Abstract: A gauging-stop used when bevelling the edges of rectangular material (A) of variable thickness (S2) by a circular saw (B) has an arm (1) and locking mechanism which moves horizontally in guide-rails (7) which carry a calibrated scale (2). At right angles to the arm (1), a lockable (5) slider (4) carries a gauge-probe (6) profiled to the required bevel angle. After cutting the first bevel, the gauge-probe (6) is positioned to coincide with this edge in both X and Y directions and the necessary relative movement between the saw (B) and material (A) to provide a specified inner dimension (L1) set via the scale (2). The second bevel is then cut after angling the saw blade (B) through 90 deg. for the 45 deg. bevel shown. USE/ADVANTAGE - Enables material of different thickness to be bevelled to constant inner dimension using single calibrated setting of arm in X direction since gauge-plate moves only in direction of bevel angle thereby eliminating effect of Y direction thickness and allowing use of calibrated X scale. Bevel angle can be varied by changing profile of gauge-plate and angle saw blade to suit.

Title: Cooling sheet of extruded thermoplastic and paper waste - uses endless steel band to support sheet while cooling
Inventor: SCHLOESSER HELMUT
IPC: B29C48/08
Filed: 1992-08-13
Abstract: A plant for making sheets from thermoplastic and paper waste by extrusion has a cooling section consisting of an endless steel band (12) running round rollers (13a,13b). The band has a roller pair (14a,14b) and a top roller (15) over the rear band roller (13a). The cooling band (12) is followed by double sided adhesive application and the laminating of cover layers on both sides of the sheet. Pref., an extruder (10) feeds a sheet die (10a) which is inclined downwards towards the steel band (12) on which the sheet is deposited. The extruded sheet is compacted by a roller pair (14a,14b) and sized accurately by a roller (15). Cooling can be assisted by a water spray and is completed on a roller conveyor (16) which follows the steel band (12). Adhesive is applied through two slit nozzles (17a,17b) and cover sheets from coils (21a,21b) are laminated on both sides by rollers (23a,23b). The sheets are then edge trimmed (11a), cut (11b) and stacked (24). USE/ADVANTAGE - For cooling thick sheets made by extruding thermoplastic and paper waste. The freshly extruded sheet is supported by the steel band until it has cooled enough to be self-supporting so that processing breaks are avoided.

Title: Testing information memory of time stage and combined time-space stage of coupling bay of digital time multiplex telephone exchange - cyclically printing and recording incoming multiplex lines and freely selectable control with test addresses and information
Inventor: TROOST MARCEL ABRAHAM DIPL ING
IPC: H04M3/24
Filed: 1992-09-29
Abstract: In exchange operation on time multiplex lines for incoming transmission in time positions telephonic information delivered from time channels is cyclically printed into memory cells individually arranged in the time channels for a PCM word. Control is by means of control addresses supplied from a cyclically read out holding memory and freely selectively read out on multiplex lines for outgoing transmission. In test operation, the cyclical printing and recording of telephonic information is prevented and despite this, controlled by control addresses contained in a test address register (RADR). A test pattern contained in a test pattern register (RDTI) is freely printed into the memory cells of the information memory (SM) and, using the control addresses, is read out in an output register (RDTU), from which it is fed for comparison with a test pattern in the test pattern register (RDTI). ADVANTAGE - Test requires min. input of control and hardware.
