Title: Three-stage roasting of bulk material - in internally heated predryer and externally heated rotary pre-roast and final roast tunnels
IPC: F27B19/04
Filed: 1981-08-24
Abstract: The installation is intended for roasting bulk material as preparation for further treatment. It comprises a rotary tunnel containing an axial burner to pre-dry the material at around 100-105 deg. centigrade, the resulting vapour and combustion gas passing to a precipitator. The pre-dried material is fed to a rotary pre-roast tunnel externally heated to around 850 deg., and from there to a rotary final roasting tunnel externally heated (15) to around 1350 deg. The vapours developed in the tunnels are extracted and together pass to a separate precipitator, whilst the combustion gas from their respective heating chambers is extracted (at around 800 deg.) and together pass (23) to the pre-drying tunnel (2). Appts. is used for roasting bulk material in preparation for further treatment. The amound of vapour (7,13) to be seeded with precipitation agent and handled by the precipitator is considerably reduced.

Title: Electronic musical instrument - uses digital key codes to produce reverberation effect
IPC: G10H1/18
Filed: 1983-02-09
Abstract: This electronic musical instrument uses digital circuits to produce reverberating effects. The keyboard coding circuit (101) produces a key code (KC) which is fed to a tone code detector (6), a code comparator (3) and a memory (2). The comparator compares the key code with the memory output and controls a reset signal generator (5). If all channels of the key code memory (2) are being used, this is detected by a 'curtailing' circuit (9) and used to generate a reset. The current key pressed will be registered by another memory (7). The main key code memory is a circulating shift register.

IPC: F16C33/00
Filed: 1986-10-13
Abstract: A bearing system comprises two hydrodynamic bearings (5, 7) by means of which two bodies (1, 3) having two cooperating bearing surfaces (9, 11) are supported for rotation relative to one another about an axis of rotation (2). At least one of the bearing surfaces of each of the bearings has patterns (13, 15) of helical grooves for building up pressure in a lubricant between the bearing surfaces during rotation. Further, the bearing system comprises a chamber (17) which is arranged between the hydrodynamic bearings and, which serves as a reservoir for an additional amount of lubricant, which chamber is bounded by two cylindrical wall portions (19, 21). The two cylindrical wall portions are off-centred from each other to build up pressure in the lubricant in the chamber during rotation Figure 1.

Title: Advertising poster attachment system - uses pre-glued backing and adjustable vacuum table with two aluminium plates glued to tubular frame
IPC: B44C3/08
Filed: 1987-04-16
Abstract: The poster attachment system uses a pre-glued backing and a vacuum task which comprises two aluminium plates glued to a tubular frame, which is use when evacuating the chambers. Enclosed air and other irregularities are sucked away by the vacuum such that curled or rolled material can be mounted without problem. Superfluous material is cut off and and no excess glue remains on the edges of the poster. The table is used to evacuate the material to be mounted by the application of the chamber system. This allows an upper plate to be evacuated and the degree of vacuum to be adjusted by a slide system to allow extra suction for curled or in even material.
Patent NL-8801053-A (NL)
Title: Expansion chamber and pressure regulator - has integrated flow control mechanism for liquefied petroleum gas from tank to IC engine
IPC: F02M13/08
Filed: 1988-04-22
Abstract: The liquid gas is fed via the input of the expansion chamber and regulator to a heat exchanger heated by the engine cooling water. The evaporated gas is fed to a first stage regulator, where the pressure is stabilised w.r.t. the load, by a connection to the variable manifold under-pressure in the membrane chamber. The gas flows to a needle valve which remains closed when the engine is not running. When the engine is running, differential pressures on a second membrane adjusts the position of the pin in the valve seat. If liquid petrol is being pumped to the engine, the pressure in the petrol feed line operates on the rear end of the valve pin and prevents any gas flow to the engine. The valves for ignition pulses and fuel pressure can be electronically synchronised by a control unit. (9pp Dwg.No.0/1 Original not reproducible :).

Title: Lipping for a door, in particular a glass door
IPC: E06B3/02
Filed: 1988-11-25
Abstract: The invention provides a lipping for a door 1 (for example a glass door), which is formed by an H-section 4 with two parallel jambs 5, 6 and a connecting jamb 7, which together form two recesses 15, 16 which are located opposite one another, and a wedge section 17, one recess 16 of the H-section surrounding the corresponding side of the door 1, and the said wedge section 17 being held clamped inside the opposite recess 15 of the H-section. The necessary clamping around the edge of the door is effected by the wedge section 17 which is pressed into that recess 15 of the H-section which is remote from the door 1. The pressure which the wedge section 17 exerts on the inside of the latter recess 15 of the H-section is transmitted via the connecting jamb 7 - which to a certain extent has a hinge action - to the inside of the opposite recess 16 - which surrounds the side of the door 1. This avoids the use of bolts, resulting in a lipping which is completely smooth on the outside.

Title: Animal bedding and animal husbandry
IPC: A01N/
Filed: 1982-11-23
Abstract: Bedding for poultry is formed by a litter consisting of a layer of short strips or pieces of absorbent non-toxic paper. The paper, e.g. in the form of newspaper sheets, is first shredded. The shreds are then cut into short strips or small diced pieces which are used as the bedding material. The pieces have a size distribution such that they congeal and form a surface crust or cake at an early stage of use and subsequently break up to form a readily friable material. The layer may take the form of a 'top dressing' covering an existing bedding material to extend its useful life.

Filed: 1991-02-08
Abstract: A system and process for sizing wood chips to provide a flow of wood chips which are acceptable for feeding to a digester of a pulping system. A flow management screen station is rovided which divides an incoming unacceptable flow (F0) into two fractional flows (F1, F2), neither of which is acceptable for feeding to the digester. One of the output flows from the flow management screen is concentrated in oversized and overthick chips compared to the incoming flow. The other output flow is concentrated in undersized chips and particles compared to the incoming flow. The output flows from the flow management screen are then fed to second and third screens (16, 14) which separate "overs" and "unders" from the respective flows to provide acceptable flows to the digester. <IMAGE>

Abstract: The present invention relates to a method for PRODUCTION OF wooden chips used in the food industry for smoking of meat, fish, sausages, smoked processed cheese and other smoked products, as well as in the production of high-and low-alcoholic beverages. The beech wooden chips produced by this method ensure quality smoking of the meat products and give the smoked product a specific and fine flavour. The oak chips imitates aging of the beverages in a barrel and improves the quality of natural taste and flavour, enhancing the characteristics of the grape or the fruit. Thus, the oak wooden chips add extra flavour and taste to the beverages. The method includes prior preparation and cutting of the logs, heat-processing in water steam chamber, kiln-drying, longitudinal cutting along the pore of the wood into small particles to the respective sizes and de-dusting of the crushed particles in a de-dusting facility. The production of beech chips includes passing through a sieve for sorting of the different grades, and then packaging of the chips per grades. The production of oak chips includes additional heat treatment of the wooden particles, such as baking in thermal facility under certainconditions.
