Title: Compensating centrifugal forces in a rotary rotary tool head
IPC: B23B51/10
Filed: 1980-12-23
Abstract: A rotary tool head comprises a support member 1 which is to be secured to the spindle of a machine tool. The support member has at least one radially adjustable slider 4 which carries a tool 5. An adjusting rod 7 is displaceable coaxially with respect to the support member 1 and acts on at least one rack 8 with inclined teeth 8a which is axially movable in the support member 1. On the slider 4 a toothed bar 10 extends in the direction of slider movement and has teeth 10a in mesh with the rack teeth 8a and inclined at the same angle  beta as the rack teeth 8a to the axis of rotation. An additional toothed bar 11 extends in the direction of slider movement and cooperates with an additional rack 15, e.g. via a pinion or pinions 12, which is axially movable in the support member 1 and is so biased by a prestressed spring assembly 16 that the spring assembly 16 applies to the slider 4 a force which is directed radially inwards towards the axis of rotation. This force opposes centrifugal force acting on the slider 4 and thereby reduces wear on the teeth of the rack 8 and the bar 10. The spring 16 act against the rod 7 or the support member 1. <IMAGE>

Title: Conveyor system
IPC: B02C23/02
Filed: 1981-08-26
Abstract: The invention is concerned with a conveyor system, designed to prevent disruption at the junction of a first armoured face conveyor section and a second conveyor section, as happens when large pieces of cut material cut from a mine face e.g. coal are encountered.

Title: Portal frame structure resistive both upward and downward loads
IPC: E04C3/40
Filed: 1981-11-06
Abstract: Vertical supports 11, 12 are secured to the ends of truss 10. Between these ends there is a joint- arrangement 13 such that in both upward and downward directions of load on truss 10, outside elements is, 16 on one side of the neutral axis X- X of truss 10 are maintained in compression, and that outside truss elements 18, 19 on the other side of axis X-X never subjected to compression. Figure 2 shows a joint-arrangement 13 comprising linkage 17 with pivot- joints 14, 20, 21, 22, rods 23 and 24 engaging the pivots by a thread, so that the linkage lengths may be set to provide a predetermined tension, which may be zero. When a downward load is applied, the tension in linkage 17 decreases, and when it reaches zero, linkage 17 collapses so that no compressive load is experienced by upper truss members 18, 19. In these circumstances, the frame may effectively be converted from a 2-pin to 3-pin frame. Figure 3 and Figure 4 (not shown) show joints at end of truss 10 and at feet of support 12, respectively. <IMAGE>

Title: Electrical vernier measuring apparatus
IPC: H03M1/00
Filed: 1982-03-02
Abstract: An electronic vernier linear or rotary measuring apparatus utilizes groups of stationary conductive plates 22 and a movable conductive wide bar 24. The wide bar is capacitively coupled to stationary commutator-like conductive strips 48 to provide a greatest capacitance when the movable bar is positioned juxtaposed with one of the stationary plates and a portion of the stationary commutator element. Individual plates of sub-pluralities of stationary plates are electrically interconnected to individual plates of adjacent sub-pluralities of stationary plates. Each of the stationary plates is provided with a stripe-like portion directed towards its associated commutator-like element. An RC oscillator circuit 156 is selectively coupled via gates TG1 to TG12 to each commutator-like element for a time period, during which each of the stationary plates in a sub-plurality is likewise coupled to the frequency determining input terminals of the oscillator circuit. Frequency of the oscillator is monitored each time an individual stationary plate of a sub-plurality is connected into the oscillator circuit. Vernier measurements are accomplished by comparing the output frequency of the RC oscillator 156 circuit during changes in capacitance, determined by the location of a plurality of vernier-like disposed narrow movable conducting bars, carried on the substrate. <IMAGE>

Title: Twin-needle synchronized type single-gauge aneroid sphygmomanometer
Inventor: CHEN HSU-CHING
IPC: G01L7/10
Filed: 1982-11-24
Abstract: This invention discloses a twin- needle sphygmomanometer in which systolic and diastolic needles are synchronized during initial pressurization of the pressure cuff. As pressure in the cuff is bled, both needles remain synchronized until the first Korotkov sounds are heard. Then, actuation of first control relay stops the systolic needle. Upon detecting the last Korotkov sounds, second control relay acts to stop the diastolic needle.
Patent GB-2110729-A (GB)
Title: Positioning and transferring spinning cops
Inventor: KRENMAYR WILLI
IPC: B65H67/06
Filed: 1982-11-30
Abstract: Spinning cops arriving in an irregularly distributed and partially straightened manner are supplied individually or groupwise to an end plate 1 of a conveyor, on which they reach a stop 4 and are there stopped in a parallel position. A sliding beam 9 moves the spinning cops onto a storage plate 8 and from there to a transfer point of an elevator 10. Before performing the displacement movement, the end plate 1 is stopped by a sensor 5 when the cops strike the stop beam. A second sensor 6 positioned upstream of the first sensor interrupts the further supply of cops on detecting the cops already engaging with the stop beam. The displacement movement takes place when a third sensor 19 at the transfer point indicates that there is a deficiency of cops. As only the parallel alignment and not the individual arrangement of cops takes place on the end plate, the apparatus is simple, because the individual delivery is ensured by the storage plate, the latter being responsible for the individual delivery of spinning cops to the elevator. The apparatus can be part of a complete installation into which, at the inlet side, the spinning cops are introduced in an irregularly arranged manner. In practice, only limited presorting is required, transfer taking place in a simple and reliable manner from the end plate to the storage plate. <IMAGE>

Title: Method of making sealed packages for spreadable products
Inventor: REDMOND SANFORD
IPC: B65B63/02
Filed: 1982-12-20
Abstract: A method for making sealed packages for spreadable products 6 includes feeding a thin flexible sheet material 36 cutting such flexible material into predetermined lengths, and shaping each cut length of flexible material, e.g. on a vacuum drum 56 into a predetermined three- dimensional form. The three- dimensional form is transported to a position over a stiff base 112 with the spreadable product thereon where the formed flexible sheet is cohesively joined along its outwardly extended edges to the base member to enclose the spreadable product positioned thereon. The longitudinally extending edges of the flexible sheet and base member may be further pressed into cohesive engagement by a roller assembly 91 which contains resiliently mounted blades which further compresses the leading and trailing edges into cohesive engagement. Preferably a final tamper 132 then tamps the pleats shut. The spreadable product being packaged may also be shaped and sized by the tamper. <IMAGE>

Title: Blasting mask and method of making and using the same
Inventor: COOPER LARRY L
IPC: B41N1/24
Filed: 1983-12-23
Abstract: The blasting mask can comprise a thin backing sheet (38) of polyester, and a layer (40) of polymerizable material affixed to the backing sheet and being of a predetermined size and shape. The blasting mask is preferably made by photographing a shape to be reproduced to form a negative. A blasting mask blank is then provided which comprises the backing sheet and a uniform layer of polymerizable material thereon. Ultraviolet light is shone through the negative onto the blank which polymerizes the material from a monomer to a polymer in the areas where it receives the ultraviolet light to harden it. The remaining material is washed away to leave bare spaces on the backing sheet. The resulting mask is adhered to grit- erodible material in which the shape is to be reproduced, and blasting grit is directed toward the grit-erodible material for a sufficient time to erode the erodible material to a desired depth. The blasting mask can be placed on the grit-erodible material with the backing sheet contiguous with the material or with the hardened material contiguous with the grit-erodible material. In the latter instance, the hardened material can be adhered to the grit-erodible material and the backing sheet peeled away from the hardened material. <IMAGE>
