Title: Flame tube boiler with waste air afterburner - preheats combustion air and deals with fluctuations in heat demand
Inventor: CLEVE URBAN DIPL ING
IPC: F22B7/12
Filed: 1976-04-09
Abstract: The flame tube boiler plant is used for combined steam and heat generation and for thermal combustion of the process waste air to be cleaned. The plant is designed to meet the fluctuations in the steam or heat generation required and the constant flow rate of the waste air containing e.g. foul smelling substances from industrial processes. The flame tube boiler with heater has additional burners for the afterburning of the process waste air. The waste gases from the afterburner pass only through a single flame tube and emerge hot from the boiler. This heat is used for preheating boiler air after mixing with cold flue gases. Alternatively the cold flue gases can be tapped and supplied to the air preheater.

Title: Mould closure assembly has removable guide bars - giving clearance for larger moulds also adjustable plate positions
Inventor: HEHL KARL
IPC: B29C45/40
Filed: 1976-05-25
Abstract: A mould closure assembly for an injection moulding machine comprises a movable, hydraulically driven clamping plate travelling on guide bars, relative to a stationary clamping plate. One or other of these movable or stationary plates is adjustable relative to the guide bars by threaded adjustment sleeves operating in conjunction with threaded locking sleeves, the adjusting and locking sleeves are rotated together to effect the adjustment and are then forced axially apart by a small distance to effect the locking action. The load-bearing plates which receive the reaction from the locking sleeves are removable and the locking sleeves can be axially clamped relative to the associated threaded adjustment sleeves by means of threaded nuts or the like between them, when the load-bearing plates ahve been removed, the guide bars can be disconnected at their far ends from the machine and can be axially withdrawn, to provide access clearance into the space occupied by the mould. Pref. the adjustment sleeves have external threads, and all these sleeves are rotatably synchronously driven by a manually operated drive device esp. a pinion By making one or all of the guide bars removable the space define by the area of the mould support plates can be more fully utilised, since the guide bards no longer obstruct access to it. for example for a square or rectangular mould.

Title: Evaluation of precious stones - using narrow light beam whose cross section is equal to smallest inclusion to be detected
Inventor: BRUECK GERNOT KLAUS
IPC: G01N21/87
Filed: 1976-05-26
Abstract: The stone (5) is examined with a narrow light beam whose cross section is of the same order of magnitude as the smallest inclusions to be detected. The beam is moved over the whole of the cross section of the store perpendicular to its direction of incidence along paths whose spacing are less than or equal to the beam cross section. The intensity of the light beam is modified by the stone under examination and measurement of this intensity gives the required data. Well-spaced, paralle light rays fall on the precious stone and are focused s.t. their focal point is on the stone itself (5). This focus is displaced along a perpendicular to the plane of the cross section. the stone may be moved continuously to and fro to achieve this displacement or, alternatively, a system of lenses (2) may be moved in the same manner.

Title: Interference signals detector for receiver - has parallel RC circuit between transistor emitter and frame, with large time constant
Inventor: HANSEN JENS DIPL ING
IPC: H03G3/34
Filed: 1976-11-24
Abstract: The receiver has an electronic interference suppression device as in 2613470 with a gate in the signal path. Useful signal containing interference pulses are applied through a clamping circuit to an amplifying transistor which amplifies pulse-like signals, but is ineffective for sinusoidal signals. The signal with interference pulses is applied to the base of an emitter follower, whose emitter is connected through a capacitor to the base of a second transistor connected to frame through a diode. The diode forward direction is in parallel with the base-emitter path of the second transistor. The emitter of the amplifying second transistor (T2) is connected through a parallel RC circuit (R5, C4) to frame. The RC circuit time constant is large in comparison with the interference pulse rise time.
Patent DE-2655256-A1 (DE)
IPC: G03B27/34
Filed: 1976-12-07
Abstract: In the optical device for automatic focusing of reproduction units, a lens (5) is used to project an original mounted on an original gate/trap (10) onto a film gate/trap (4). An optotransmitter (15) mounted on the device so as to be incapable of displacement relative to the lens (5) emits three mutually bordering light sectors. Arranged at prescribed distances which depend on the focal length f of the lens are optoreceivers which via connected tracking circuits control positioning motors which control the distances between gates/traps (4 and 10) and the lens (5). In order to exclude the effects of unsharp and mutually overlapping edge regions of the light sectors, the two photoelectric elements of each optoreceiver (12 and 14, respectively) are offset relative to one another perpendicular to the planes defined by the light sectors, in order that only light of the assigned sector can fall onto a photoelectric element. <IMAGE>

Title: Tyre with reinforced tread - has wire loops embedded around circumference in grooves forming spiral
Inventor: SCHEFFLER GUENTER DIPL ING
IPC: B60C27/00
Filed: 1977-02-21
Abstract: The reinforced tyre tread has grooves running around the circumference with metal cables threaded through them. The cable loops prevent the tread from being torn off the carcase under high speeds or when in use over rough ground. The grooves can be in a spiral so that an endless loop of cable can be used. The cable can be laid to protrude from the upper surface of the tread so that improved ice grip is produced without damage to road surfaces.

Title: Oil cooled rotary compressor injection system - has vent hole to prevent air accumulated during shut=down disrupting oil flow
Inventor: BORN HEINZ
IPC: F04C29/04
Filed: 1977-03-11
Abstract: A rotary air compressor (5) has oil injected for cooling and sealing. The discharge passes through an oil separator (1) from which the air goes to an after cooler (10) and the oil to an oil cooler (4) with a thermostatically controlled bypass (12). There is an oil storage vessel (3) between the cooler and the oil injector (15). The outlet pipe (6) from the vessel projects from the top of the vessel to below the oil surface. It has a small hole (7) in its top. An air pocket can accumulate at the top of the vessel when the compressor is shut down. On start up the air enters the oil stream slowly through the small hole (7) and thus prevents large bubbles of air from disrupting the oil flow.

Title: High speed battery charger with cell protection - monitors charge via terminal voltage and regulates rate at different stages
Inventor: LAVELL MAURICE
IPC: H02J7/00
Filed: 1977-07-04
Abstract: A battery charging circuit is intended to achieve max. charge in the min. possible time without damaging the cells. The charge is independent of the battery characteristics. The battery being charged is monitored via the terminal voltage. The charging current is relatively high and practically constant while the terminal voltage rises relatively fast. During the next stage the current gradually drops to the final level at a speed which allows constant increase in the terminal voltage of the battery. The time taken for the first two stages is estimated and the process is continued to the final value of current for a period which is a function of the estimated time arrived at by an electro-chemical process.
