Title: Cable haulage mechanism between rotary items - has part of cable wound onto spiral leaf spring in housing
Inventor: EPP PETER
IPC: B65H75/34
Filed: 1977-04-22
Abstract: The haulage mechanism is for one or more cables or hoses running between two items rotating in relation to each other, partic. in automatic manipulating machines. A housing (19) with sidewalls (16, 17) accommodates a spiral leaf spring (20) supporting the hose or cable (13) part of which is wound onto it, and whose ends extend from the inner and outer part of the housing. The hose is secured only at the ends to the two items (4, 6). The edges of the leaf spring can be held clear of the housing sidewalls by sliding shoes, and the hose or cable can be secured by rib-type holding-down devices to the spring, so as to slide on it in the lengthwise direction.

Title: Self-loading lorry with tailgate hoist - has servo powered moving floor whose stroke is adjustable to unit size of load
Inventor: VIELBERTH JOHANN DR
IPC: B60P1/44
Filed: 1977-04-26
Abstract: The self-loading lorry has a servo powered moving floor (21) which moves loads to and from the servo operated tailgate hoist (6).

Title: Ion:implanted pn junction - has thin recombination layer of dopant concentration intermediate that of two junction regions
Inventor: ELLIOTT GEORGE H
IPC: H01L29/861
Filed: 1977-04-30
Abstract: The semiconductor junction has a relatively heavily doped region of first conductivity type, a relatively lightly doped region of opposite conductivity type. Immediately adjacent the effective junctoin is a thin 'recombination layer' of first conductivity type and of dopant concentration intermediate that of the two junction regions. Preferably, the recombination layer overlaps the forward biased depletion region of the junction and has a thickness (typically 50 A to 200 A) much less than that of the junction depletion region under reverse bias. The recombination layer dopant ions thereby provide recombination-generation centres only where beneficial to improve the forward and reverse recovery times of the junction without degrading the steady state reverse current characteristics.
Patent DE-2721276-A1 (DE)
Title: Continuous counting of electrical pulses by moving average - involves two=way counter with divider fed from reference frequency
Inventor: FILBERT DIETER PROF DR ING
IPC: G01R23/02
Filed: 1977-05-09
Abstract: The continuous counter consists of an up-down counter (Z) to whose forward counting input is connected the pulse train to be measured (fx). The data output of the counter controls a digital divider or rate multiplier (T). The divider divides the reference pulse train from a clock generator (fo) in accordance with the digital output of the counter. The resulting signal is fed to the reverse counting input of the digital counter (R). The figure appearing in the counter display (A) is the moving (exponential) average of the frequency of the pulse train being measured (fx). The average period of the pulse train can also be continuously measured if this signal is fed to the input of the divider and the reference frequency (fo) is fed to the forward counting input (V) of the digital counter.

Title: Roller shutter made from horizontal strips - has strips with edges wedging firmly preventing rattling in closed state
Inventor: HELSHOEJ EGON
IPC: E06B9/262
Filed: 1977-05-14
Abstract: The roller shutter arrangement is used as a retractable wall, gate or curtain. It has several relatively thick strips which are connected by flexible supports for forming a continuous shutter arrangement. These strips are guided by their ends between two vertical parallel profiles with a clearance. The strips in the lowered condition are closed firmly between the guide profiles so that the shutter does not rattle in the wind. The strips have longitudinal inclined surfaces. The latter are arranged at an angle between the profiles so that in the lowering of this shutter the strips are wedged on the successive lower strips. The strips are arranged at such distance from the each other that the flexible connector is folded to ensure the firm wedging action between the strips.

Title: Corner joint for laminated chipboard panel - has complementary edges divided except for coating which presents continuous outer surface with no gap
Inventor: APPELBAUM WERNER ING GRAD
IPC: B27G5/00
Filed: 1977-05-26
Abstract: The process is for producing a rounded corner connection with no joint gaps on the outside, using a deformable decorative panel of coated pressed material and panel-shaped support material, esp. chipboard. The support material is worked away on one side at the corner point, towards the proposed joint edge, forming a rounded part profile and further straight one. A panel of pressed material is applied to this side, covering the worked area. The same chipping tools are used to work out a depression on the opposite side, complementing the profiles produced in the first stage, and the material is divided into the two parts forming the corner joint, still connected by the covering layer.

Title: Washing and drying machine for cutlery - has rotary mounted inclined holders ensuring change of position and effective removal of food particles
Inventor: KLASS GEORG ING GRAD
IPC: A47L15/30
Filed: 1977-07-13
Abstract: Machine is provided with cases or cartridges (6) for the cutlery, medicine spoons etc. these cases being mounted in a rotatable holder (4) where they are inclined inwards at an angle to the vertical. The centre ring of the holder (4) is designed as a pump wheel (5) and the holder is mounted on a drive motor (2) fitted with a brake. An annular container which is used both to hold the water and provide the resilient bearing for the drive motor surrounds the rotating parts and acts as the support for further components. The food particles can be removed from the water by an annular sieve insert (11). A force component is produced which prevents the cutlery from flying out but allows the water to drain off. Since the rinsing water is fed in from the top to bottom tangentially it gradually speeds up and washes the food down. As the rotation increases the cutlery change their relative positions to ensure proper cleaning and drying of all surfaces.
