Title: Conveyor belt even loading equipment - has ploughshare-shaped deflectors directing material towards centre of belt
Inventor: BIELIG REINHARD
IPC: B65G69/04
Filed: 1980-07-26
Abstract: The equipment gives even loading of a conveyor belt used in conjunction with a bucket-wheel excavator. Opposite and immediately after the bucket wheel discharge point or the belt loading point in the transport direction is a deflector (1) on the steel supporting structure (2) of the conveyor (3), at an acute angle to the transport direction (4) and above the belt. This is of ploughshare shape, deflecting the material falling onto the belt towards the centre of the latter, in conjunction with a second one (9) on the opposite side, so as to spread it evenly over the belt. To avoid any build-up of material, the deflectors are inclined upwards in the transport direction for 10 to 30 deg. their undersides being far enough above the belt to allow free material flow underneath.

Title: Disc brake calliper guide system - has two components moving axially between stops
Inventor: BURGDORF JOCHEN DIPL ING
IPC: F16D65/54
Filed: 1980-08-02
Abstract: The guide and adjustment system is for the floating calliper of a disc brake, accommodating disc deposits and/or calliper distortion. One or more guides are provided on the brake bracket, there being a friction joint between it and the calliper. First (18) and second (19) components both move in the axial direction, the first one between two stops (33,34) on the calliper. The second one is moved only by two stops (33,36) spaced apart in the axial direction on the calliper along the guide (4) on the bracket after the friction has been overcome. The components strike against each other in the brake application direction.

Title: Sewer type mud suction vehicle - has advance chamber, jet pump and centrifugal pump for continuous water return
Inventor: KLASS GEORG
IPC: E03F7/10
Filed: 1980-09-09
Abstract: A discharge flap is provided on the rear end of a tank, fitted with mud chamber, on a vehicle for sucking up mud. This flap has an advance chamber tank (5) fastened to it, connected to the mud chamber (1) by an overflow dam (6). Surface water is removable from this via a suction pipe (8) on a jet pump (9), fitted with a float (10) near the suction hole. The pump is preceded by a centrifugal pump (11) from which the driving nozzle (13) of the jet pump is activated via a branch pipe (12), water largely cleared of solid particles being returned to the sewer or duct via a conveyor pipe (14).

Title: Winding plastics tubing onto a mandrel - including heating opposite sides of the tubing to improve bonding without distortion
Inventor: RHODES RICHARD OLNEY
IPC: B29C48/09
Filed: 1980-09-26
Abstract: Plastics tubing is wound onto a mandrel under controlled speed over a guide shoe. Prior to passage over the shoe one side of the tubing is heat softened. The other side of the tubing is heat softened whilst in the mandrel so that in the wound tube the heat softened side of adjacent turns are in bonding contact. In an illustrated embodiment, the tubing is fed from an extruder via a tensioner which stores a length of tubing. The length in the tensioner is monitored and the mandrel speed controlled to ensure a constant length and thus constant feeding tension. The shoe pref. is in the form of a fixed part spiral which urges the tubing over the mandrel surface. The selective heating of opposite sides of the tubing prevents distortion, i.e. twisting, but maintains a good bond. Solar heating panel arrays can be made.
Patent DE-3038287-A1 (DE)
Inventor: SCHAPER WERNER
IPC: B01D19/00
Filed: 1980-10-10
Abstract: 1. Process for the removal of residual vinyl chloride from vinyl chloride polymers, which, after polymerisation, are present in the form of an aqueous dispersion, wherein the aqueous polymer dispersion is brought to a temperature which is at least equal to the freezing temperature of the polymer, preferably to a temperature below 120 degrees C and is subjected to an entrainment by steam and is degassed, wherein in a first period of time heat is supplied, directly or indirectly, preferably through the steam serving as inert fluid and degasification means, and in a second period of time after a throttling and subsequent disconnection of the supply of steam, a lowering of the pressure or an application of an underpressure is carried out in the degasification such that the boiling of the aqueous polymer dispersion continues to be substantially maintained without an external supply of heat and, with the aid of the steam-formed from the aqueous dispersion, the entrainment of vinyl chloride or degasification is continued, wherein the steam containing vinyl chloride is condensed, the vinyl chloride is passed to a recovery section and the condensed water containing vinyl chloride is introduced in whole or in part into the aqueous polymer dispersion, characterised in that the condensed water containing vinyl chloride is not passed directly into the aqueous polymer dispersion, but is passed in counterflow to the steam emerging and/or formed from the polymer dispersion and is distributed, sprayed or injected at or after the point of entry in the steam containing vinyl chloride.
Patent DE-3046292-A1 (DE)
Title: Fabric drier - has air-stream moving with and against material to give continuous single pass drying process
Inventor: SCHRAUD ALFRED DR
IPC: F26B13/10
Filed: 1980-12-09
Abstract: The spreaded fabric is fed longitudinally through a zone contained at the sides. At the same time, an air/steam mixt. is passed longitudinally through the zone to dry the material. The longitudinal tension on the fabric is kept as low as possible while passing through the drying zone. The drying medium, with over a 50% steam content, is introduced at about the centre of the fabric length so that part flows with the material movement and part flows against the direction of fabric travel, with the air/steam moving in a zone with a smaller cross section with the fabric than in the counter-stream section, to give a faster gas flow with the fabric than against it. The zone carrying the fabric and drying air/steam mixt. is corrugated longitudinally, contained at the sides, and the air/steam is recirculated. The process gives a continuous drying action on the fabric, fed through the drier in one pass.

Abstract: In the case of the watch proposed by the invention, a datewheel (26) which is internally toothed and serves for indicating the date is provided. Arranged inside the opening of the datewheel (26) is an externally toothed day-of-the-week wheel (27), which is connected to a disc (40) which bears on its upper side an inscription for the days of the week in two languages. Arranged between the datewheel (26) and the day-of-the-week wheel (27) is a common advancing device, which uses a cam (14) to tension a spring (17). If the tip (16) of the cam (14) is passed over, the spring (17) moves a switching element (15) quickly by a limited angular amount, the ends (24) of the switching fingers (23) of the switching element (15) advancing both the datewheel (26) and the day-of-the-week wheel (27). A correcting device with two gearwheels (32, 33) is provided. Upon rotation in one direction, the said gearwheels use an extendable pawl (36) to advance the datewheel (26) by one tooth interval. Upon rotation in the other direction, the day-of-the-week wheel (27) is advanced in the same way by one tooth interval. Both devices are covered by a one-piece plate (41). <IMAGE>

Title: Tensioning device
Inventor: POHLE HELMUT
IPC: B65G23/44
Filed: 1981-10-01
Abstract: In underground mining and tunnelling and also in the transport of bulk goods on the surface, belt conveyors, chain conveyors and rope-driven monorail conveyor installations are secured by means of tensioning cylinders which are designed as hydraulic cylinders with an allocated hydraulic accumulator having a nitrogen bubble.
