Patent SE-500654-C2 (SE)
Inventor: GUSTAFSSON PER
IPC: E21B4/14
Filed: 1987-07-14
Abstract: In a water driven down-the-hole rock drill, the rearward end of an associated hammer is provided with a drive piston reciprocable in a cylinder located adjacent the rear of the drill. The front end of the hammer is guided for reciprocation in a bearing located adjacent an anvil of a drill bit. Between the cylinder and the bearing the hammer is elongated and enlarged diametrically relative to the piston. The enlarged hammer portion reciprocates freely in a chamber formed by an outer casing of the drill. Drive water is expelled from the cylinder and flushes the hole drilled by the bit. An open ended tubular valve reciprocates to control a duct connecting the interior of the valve to coaxial through-flushing channels in the hammer and the drill bit.

Title: Plate for floor heating system
Inventor: ROSENBERG JAN
IPC: F24D/
Filed: 1990-06-05
Abstract: A floor heating system for a joist frame. A normal floor plate (1) of particleboard is provided with several longitudinal grooves (4) with a dimension so that heating pipes (6) press fit in the grooves. Aluminium foil (5) is applied in the groove and on each side of the groove to conduct heat from the heating pipe to the upper surface of the plate. A section of a similar floor plate with grooves is used as a swivel plate and is thus turned upside down to steer the heating pipes down into a compartment between the joists in the joist frame where the heating pipes can be turned 180 degrees and where connections can be arranged. A thin parquet floor can be laid direct on these particleboards. If a plastic floor is to be used, an initial thin layer of particleboard or so called floor marsonite is laid.<IMAGE>

Title: Improving sensitivity and speech immunity in multifrequency receiver - counting and processing in real time input signal zero-crossings, in lower and higher frequency bands of dual-tone multifrequency signals
Inventor: ZIMBREK SLAVEN
IPC: H04Q1/46
Filed: 1993-10-14
Abstract: The number of zero-crossings in each band of a dual-tone multifrequency (DTMF) signal is counted and compared with that in immediately preceding measurement periods. The magnitude of any difference is established and when it is at least equal to a threshold value, pref. one, the input signal is considered to be a DTMF signal. The energy parameter, representative of the tone energy in a signal, is measured in real time in each band, and three threshold values for the difference from average values determined. The measured difference values are compared with the thresholds to determine if a DTMF signal exists. An interference frequency is accepted when occurring in successive measuring periods.

Abstract: In packet switched data transfer of the cellular radio system, the control of the transmission power comprises characteristics as well of the closed-loop control and the open-loop control. Before forming the connection and during long pauses between the packets, the terminal device measures the control signal transmitted by the base station and compares its signal power (R0) to the target level (t0), that is included by the base station in the control signal as a parameter. The base station informs in the control signal also the transmission power, whereby the terminal device sets the same power to be its transmission power, corrected by the difference between the target level and the measured quality of the link (t0-R0). In addition, also the measured quality of the link (RXQUAL) is transmitted in the acknowledgment messages of the packets, whereby the transmitting device changes its transmission power so that the quality will be controlled to the certain target level. The biggest step of the change is determined by the length of the packets. In the packet transfer downlink, the base station uses first the maximum power and corrects then its transmission power based on the measuring information included in the acknowledgment messages transmitted by the terminal device.

Filed: 1999-12-03
Abstract: The present invention relates to a vacuum operated refuse collection system generally comprising a number of individual storage spaces (3) intended for temporary storage of refuse (10) inserted therein. The individual storage spaces of the system are emptied in a predetermined or variable sequence, by operating discharge valves (RDV) through which the storage spaces communicate with a transport pipe (2) or transport pipe branch. A subatmospheric pressure is created in the transport pipes or branches, and by means of this vacuum the stored refuse is transported from the individual storage spaces to a collection central, as the corresponding discharge valve is opened and transport air is let in through an air inlet. The invention suggests controlling the drag force applied to the refuse material as well as the mixing of material and transport air, whereby this control is preferably performed during the entire emptying phase in order to optimize material flow during the entire emptying phase of the individual storage space.
