Title: Decorative corner moulding strip - comprises flexible thermoplastic strip welded between two semi-rigid thermoplastic strips
IPC: E04F19/02
Filed: 1975-07-30
Abstract: The corner moulding is formed of a pair of longitudinally extending strips (11, 12) of semi-rigid plastic material extending in spaced side by side relationship, adjacent edges of the strips being integrally connected to a strip of flexible easily bendable plastic material (13) so that the semi-rigid strips can be angularly disposed to conform to corners of surfaces to be covered. The strips are integrally joined using welding and due to the laminar construction the strip may be very thin but resistant to wrinkles. One face of the strip may be coated with adhesive and covered by protected strips which are removed prior to use.

Title: Welding T:joints between stainless steel tubes for furniture - where one tube is inserted in the other to simplify mfr.
IPC: B23K9/007
Filed: 1975-08-13
Abstract: A stainless steel tube(1) is located at 90 degrees in a second tube (2) made of the same material. Tube(2) is provided with a hole which corresponds to the cross-section of tube(1), and tube(1) is then inserted in the hole, followed by welding the two tubes at a point perpendicular to their longitudinal axes; the visible welded spot is then polished. Welding the two tubes together is pref. achieved by (a) arc welding using a stainless steel electrode with a refractory coating preventing oxidn., tube (2) being pierced by the electrode and welded to tube(1); or (b) a hole is made in tube(2) and filled when simultaneously welding the visible part of tube(1) using argon as the inert gas. Tubes (1,2) may be round, square or polygonal, and may have the same or different cross-sections. The tubes may also be joined by using an adhesive. Used e.g. in the mfr. of tubular furniture. The very simple method saves times in both welding and polishing.

Title: Sprinkler for granulator tower ensuring particle uniformity - has chamber with perforated bottom divided into separately closable compartments
Inventor: KAZANSKY PAVEL KONSTANTINOVICH
IPC: B01J4/00
Filed: 1976-07-26
Abstract: A sprinkler for a granulator tower through which molten material can be sprayed has a chamber with a perforated bottom to which the feed line for the molten material to be granulated is joined. The chamber is partitioned into independent compartments, each of which is delimited by a section of the perforated bottom, and each of which is connected by a feed pipe which can be closed to the main feed line for the molten material. The distributor feed lines may be connected to the main feed line by a pressure chamber with a double wall and a circulating system. These feed pipes have vertical sections extending into the pressure chamber with their inlets at different heights and fitted with float controlled valves. The specific loading of the perforated bottom can be fully controlled so that a product with a uniform granular size can be obtd. Compartments can be closed so as to control the loading on the perforated bottom and maintain the pressure on the material stream through the perforations at a constant value, despite variation in delivery speed of material.

Title: Appts. monitoring operation of ultrasonic testing of tubes and bars - senses echo signals by transmitter probe for amplification and application to threshold circuit
IPC: G01N29/11
Filed: 1976-10-01
Abstract: Immersion ultrasonic pulse-echo testing is applicable to tubes or bars for internal defects. There is continuous monitoring of the operation of the test channel. As ultrasonic energy enters the workpiece, the round workpiece surface causes acoustic energy scatter responsive echo signals which are sensed by the transmitter probe, are amplified and applied to a threshold circuit. If the amplitude of the scatter responsive signal falls below a predetermined level, an output signal indicative of "loss of operation" is produced. A device inhibits such output signal if there is only a momentary decrease of the scatter responsive signal below a predetermined value.

Title: Mfr. of blown thermoplastic sheet on multi-roll calender - with blowing by frictional or roll heat before take-off
IPC: B29B7/00
Filed: 1977-04-13
Abstract: Mfr. of blown sheet from thermoplastic compsns. contg. blowing agent, uses a calender with >=2 rolls, with a hank of material in at least the first nip, in which the sheet is blown during calendering before take-off from the last roll by heating to above the decompsn. temp of the blowing agent. Used for prod. of films of 100-1500 (200-1200) mu m thickness with low wt., relatively high stiffness and low cost, esp. for packaging. The process is simple, economic and versatile, i.e. independent of compsn. and the calendering process. Use of a separate high-temp. blowing roll after the calender, as in the 'Luvitherm' (RTM) process which can cause sticking and stretching problems, is avoided.
