Patent DE-2429948-A1 (DE)
Title: Boriding, siliciding and phosphiding metal parts - by coating with double oxides dispersion and strongly reductive calcination
Inventor: WUESTEFELD ALOYS DR
IPC: C23C12/02
Filed: 1974-06-21
Abstract: The diffusion of B, Si and P into a metal surface is carried out by using the double oxides of the elements, e.g. B2O3.P2O5 and SiO2.P2O5, for treatment of the metal surface by applying to the surface in the form of a dispersion and, after setting, calcining in a strongly reducing atmos. at 800-1100 degrees C. An aq. soln. of H3BO3 and H3PO4 in 1:1 molar ratio or a conc. ca. 30% H3BO3-H3PO4 soln, neutralised with alkali pref. is used to improve setting on the metal surface. The process is much simpler and cheaper than those using amorphous B or B4C powder or granulate, Si powder or P vapour.

(s.pt), due to their compsns. with addns. e.g. lampblack, which form the expansion or foaming gases. Prior to heating, oxide matls. with high m.pt. esp. natural and synthetic silicates with size 0-0.1 mm, are added to the glass powders in the ratio 0.1-3.5:5 so that either (a) on heating glass with softening pt. 700 degrees C. the oxidic matls. are coated with a thin layer of gas and are not wetted so, after cooling, the hollow glass spheres can be sepd. or (b) for glass with softening pt. 700 degrees C. sulphides are also added, esp. 0.05-2.5 VS so the complete mixt. forms a cellular glass entity. Process allows the inexpensive mfr. of hollow glass spheroids or faomed glass moulding suitable e.g. for thermal insulation.

Patent DE-2511625-A1 (DE)
Title: Counting circuit measuring and monitoring pile length - with counters relating pick numbers to warp length, esp. for towel looms
IPC: B65H61/00
Filed: 1975-03-17
Abstract: An arrangement of counting mechanisms for measuring and monitoring the length of pile yarn feeding into a loom, esp. a towel loom, during a definite number of revolutions of the main shaft, includes a first pre-selectable impulse counter which can be set back to zero, and which receives the impulses from a device actuated by a thread length measuring wheel; and a second similar impulse counter receiving impulses generated by the main shaft; the counting process of the first impulse counter being interrupted by the second impulse counter, when the pre-set count number has been reached. To register the length of the threads, two adding impulse counters (Z1, Z2) which can be set back to zero electrically, and which have electrical switches, are provided. These can be set back to zero by a pre-contact switch (14) and connected to the impulse signaller (24) of a thread length measuring wheel by a preselected impulse counter (Z3) which can be electrically reset to zero, and which registers the revolutions of the main shaft. This is associated with the pre-contact with (14) and zero contacts controlling a switching circuit. In which there are two sets of contacts (29, 33). Contacts (33) effect the alternating connection of the impulse signaller (24) to the counting magnets of the counters (Z1, Z2) registering the length of the thread, and at the same time, contacts (29) effect the alternating switching of resetting magnets of these counters (Z1, Z2) to the pre-contact switch (14) of the counter (Z3) for the revolution ions of the main shaft. Measures continuously and monitors the running of the pile threads in separate machines, esp. in towel looms.

Title: Comparison of binary numbers with programmable tolerance - combines nominal value from store with tolerance to generate upper and lower numerical values
Inventor: SCHLAPKOHL JOACHIM ING GRAD
IPC: G05B19/21
Filed: 1975-05-30
Abstract: The programmable facility allows the upper and lower tolerance levels relating to a nominal binary value to be introduced for machine tool positioning systems. The nominal value from a memory is transmittted to two arithmetic circuits that receive the tolerance value from either a decoder or part of the memory. The circuits generate an upper limit value and a lower limit value that are compared with the system counter state. A third comparator generates greater than, less than or equal to outputs by comparison of the counter state with the nominal value. A flipflop is set to generate drive signals from two gates unless upper or lower limits are reached. Once within the tolerance field, the flip-flop is reset to generate equality.

Title: Pneumatic processing plant for glass containers for refuse disposal - has chute with two discharge compartments to allow one only to be open during discharge
Inventor: REIMELT WOLFRAM DIPL ING
IPC: B65G53/60
Filed: 1975-06-13
Abstract: A glass bottle processing unit uses suction to transport bottles from supply points to a closed discharge chute located over a refuse container. The discharge chute has two compartments that are alternatively closed and opened. Bottles are entered via small hoppers (12) in a discharge line coupled to a chute. A pneumatically actuated flap (28) allows glass to be passed to one of two compartments (22, 24). A second pneumatic actuator (35) controls two flaps (32, 34). A blower (20) provides suction over a fine (18) and coarse (16) fitter. In operation one chamber (22, or 24) is discharging glass to the refuse container (36) when separate from suction by the flap (28). The other chamber is closed by the bottom flap (32, or 34) while being filled.
Patent DE-2526565-A1 (DE)
Title: Droplet separator for gases - has tapered section slats permitting higher gas flow with reduced tendency to clogging
Inventor: GLASS REINHARD ING GRAD
IPC: B01D53/26
Filed: 1975-06-13
Abstract: The separator comprises a large number of prismatic members each having a tear-shaped or aerofoil-shaped section. Pref. the prismatic members are arranged in rows stagered one after the other. By using this type of cross-section, it is found that relatively high gas speeds are acceptable with a considerably reduced risk of deposits of solids from either the liquid droplets or the flowing gas upon the separator surfaces. As a result, the effective flow rate can be increased and the risk of clogging is considerably reduced. In addition, downward flow of the precipitated liquid is esp. facilitated in the low-pressure region of the tapering section, reducing the tendency for the liquid for re-entrained in the gas flow.

Title: Awning material bar attachment end finishing - has woven edge hems forming lateral closure for tubular gripping
Inventor: FUGGER ADOLF
IPC: E04F10/06
Filed: 1975-07-16
Abstract: The awning material is for an awning with a drop tube bar and a spindle, the length of material having a tube-type edge hem for attachment to the bar and/or the spindle. Here these edge hems (8) are woven. They may form the lateral closure of the length of material; and a narrow woven edge (13) may be provided in their vicinity. This is simpler than sewing the edges round, and saves material. It also reduces the likelihood of subsequent repairs being necessary, and improves the finished appearance.

Title: Record player tone arm - is lifted and turned by control disc raising tone arm control head
Inventor: STRAUSAK BENEDIKT
IPC: G11B3/08
Filed: 1975-08-21
Abstract: The tone arm of a record player is lifted and turned without deteriorating the dynamic properties of the scanning system by masses of the control and actuating elements. The scanning system is easy to exchange and the control drive is completely disengaged when the tone arm rests on the record. This is achieved by esp. designing the rotatable control disc, on which the control head of the tone arm rests. When turned the tone arm can be deposited by lowering the control disc so that it is free from the tone arm. The activating pieces can be threads, cams, indentations, projections etc. on the central disc.

Title: Storage dispenser device for slide fasteners - has outlet opening with cutter for separating chain of interconnected fasteners
Inventor: OCHIAI KOICHI
IPC: B65D85/67
Filed: 1975-08-22
Abstract: Slide fastener dispenser comprises a housing (2) which contains the chain of slide fasteners which are pref. stored in packages having a perforated separating line (3) at their joining points. The housing has a slotted outlet opening (8) mounted in front of a cutting blade (9) which is fixed outside of the housing. To removed a slide fastener it is pulled down until its perforated separating line passes round the blade (9) whereupon slight tension is required to effect the separation. The chain of slide fasteners can be stored in the housing in zig-zag fashion or in roll form and in each case the width of the housing is not much more than that of the fastener so that numerous housings can be mounted in min. of space. Since only the front end of the fastener protrudes there is no danger of the fasteners becoming dirty. The outlet opening of the housing is pref. associated with a pressure roller (10) to prevent too fast a delivery.
