Patent DE-2523412-A1 (DE)
Title: Fastening means for securing guide rails in drawer grooves - engage in bores in drwer sidewalls and are serviceable for hollow sections (OE150376)
Inventor: GRASS ALFRED ING
IPC: A47B88/04
Filed: 1975-05-27
Abstract: A guide rail (3) can be attached to a longitudinal groove in the side wall (1) of the drawer by means of connecting members which are located in bores (9, 11) in the surface (10) of the guide rail adjoining the base of the groove and in the area of the side wall located there beneath. These connecting members then engage in the side wall of the bore of the drawer side wall ensuring a firm connection even if the side wall is designed as a hollow section. The connecting members can be in serveral forms, for example, tabs (19) which engage in the bores (9, 11) and are then bent radially outwards by means of a tool (20). Where the side wall of the drawer is a hollow section the tags can be placed against the rear side of the web covering the section.

Title: Instant picture camera with hand operation facility - has ratchet in gear train to turn rollers for cleaning or extract photograph if motor fails
Inventor: IVESTER ANDREW STEVEN
IPC: G03B17/52
Filed: 1975-11-12
Abstract: After the photographic exposure, a battery-driven motor drives one of a pair of squeeze rollers which spread the chemicals over the photographic surface and eject the finished picture. An extra facility allows the rollers to be turned by hand, e.g., for cleaning them, or to extract the picture if the battery fails to drive the motor. The hand operation is relieved of the inertia of the electric motor by including a ratchet in the gear train between squeeze roller and motor. The ratchet wheel (54) has inward-facing teeth (40) and is made integrally with the pinion (34) that drives it. The pawls (46) are carried on a pair of curved arms mounted on the ratchet wheel's axle (36) and are also integral with their pinion (48).

Title: Machine tool facing and boring head - has counter weight between bearing rear and slider guide moving radially in guide
Inventor: ECKLE OTTO
IPC: B23B29/034
Filed: 1976-03-04
Abstract: The facing and boring head comprises a bearing body to be fixed at its rear on a lathe spindle. A slider is radially displaceable on the bearing body front side in a guide vertical to the rotary axis. A positioning bar, displaceable coaxially to the rotary axis, is located in the bearing body, and its axial movement imparts a radial movement to the slider via an intermediary gear. Between the bearing body rear side and the slider guide a further guide parallel to the slider guide is provided, in which a counter weight moves radially, being equal in mass to that of the slider tool carrier and tool. Between positioning the bar and counter weight is a further gear which, by positioning bar operation imparts an equal radial movement to the counter weight to that of the slider.

Title: Compact vehicle steering lock - has blocking plate and axial drive cam operated by key
Inventor: WALLMICHRATH GUENTER
IPC: B60R25/021
Filed: 1976-03-27
Abstract: Thesteering wheel lock has a rotating cylinder which also moves axially between release and locking positions. It is retained in the release position by a locking element until the key is fully withdrawn. The design of the lock is simplified by having the axial movement cam and the locking element acting on the key slot. All the tolerances are then related to the key slot dimensions, and are not added to each other in a series assembly. The different elements are made with looser tolerances and with a stronger construction.

Title: Vibration densitometer for vibrating screen - has two probes, one generating frequency equal to screen and other generating signal as function of material density
Inventor: PONZI JOSEPH J
IPC: G01N9/00
Filed: 1976-04-14
Abstract: A vibration densitometer has a vibrating screen. A probe generates a signal of a specific frequency equal to the screen vibration frequency to stabilise it. Another probe generates a signal which is a function of the density of material flowing through the screen. The screen is so attached to the driving mechanism that it is equally spaced at all points. It is so isolated that a shift in the frequency of response is avoided if teh structure is gradually immersed in two or more different materials, or if the screen is removed mov cleaning and replaced.

Patent DE-2702938-A1 (DE)
Inventor: LEX HANS J
IPC: F24S10/75
Filed: 1977-01-25
Abstract: The heat-exchange device can be designed in particular as a roof covering or facade covering. Known plate collectors consisting of parallel sheet-metal walls are, for reasons of construction and stability, unsuitable for the construction of large areas, while single-plate devices are uneconomical for large areas as a result of their cost in terms of raw material. The device according to the invention eliminates these disadvantages by containing two series of lower or upper sheet-metal panels (1, 2) which alternately cover the area to be covered, e.g. the sheeting (10) of a roof framework, and the pipes (3) flowed through by medium at the same time forming bracing and chain links between the sheet-metal panels (1, 2). The pipes (3) lie embedded in the curved-up parts (4, 5) or bent-off edges (7), which surround in a claw-like manner from the bottom or top respectively, of the lower and upper sheet-metal panels (1 or 2), which guarantees a high heat-conduction value and great stability as a result of the lateral tensile forces exerted on the pipe. The absolutely watertight device makes possible an economical and stable covering of areas of any size, the upper sheet-metal panels (2) having e.g. dimensions of 1-30 m x 15 cm length x width and being expediently underlaid by a heat insulation layer (12). <IMAGE>

Title: Safety stirrup to release trapped foot of unseated rider - has spring loaded latch which releases stirrup when toe swings up
Inventor: MUTTER JOHANN
IPC: B68C3/02
Filed: 1977-03-18
Abstract: The stirrup (26) on a horse riding saddle is attached to a girth strap (10) by a safety connection so that in the event of a rider becoming unseated, the stirrup is released, so that the riders foot (56) is not trapped. The stirrup is secured by pins (24) to a U-shaped frame (16) and the girth strap has a ring (12) attached. The ring and frame are connected by a safety release catch. This catch consists of a swinging arm (36) with a hooked end (42) which fits into a slot through the bottom of the ring, thus securing the ring to the frame. The swinging arm also passes through a slot through a rod (28) across the frame, acting as a hinge. The swinging arm has a stop member (46) at its outer end resting on the toe (56) of the riders boot. When the toe lifts, the arm is swung up against the force of a spring around the rod (28) and the ring (12) is released.
