Title: An apparatus for wrapping sweets
Inventor: GIRNDT WOLFGANG
IPC: B65B35/16
Filed: 1983-08-17
Abstract: The invention relates to an apparatus for wrapping soft caramels, consisting of a conveyor wheel which has holding jaw pairs 3a, 3b for receiving the individual pieces W separated from a paste strand and which is equipped with a central cam disc 19a controlling the opening and closing movements of the holding jaw pairs as well as with means for the temporary delay or acceleration of the rotary movement of the holding jaw pairs which does not affect the rotation of the conveyor wheel. It is the object of the invention to increase the capacity of the conveyor wheel. The problem of the invention is to maintain a position of the holding elements that is aligned with the axis of rotation of the conveyor wheel during the rotation of the conveyor wheel. According to the invention, this is brought about in that each holding jaw pair is mounted, on the same pitch circle of the conveyor wheel, so that it can be swung out coaxially on a horizontal adjusting shaft 5 as well as on the drive shaft 1 of the conveyor wheel by means of a slideway 6, the adjusting shaft 5 being in communication, via a toothing 4, 9, with a roller lever 13 which is hinged to the conveyor wheel and rolls on a stationary cam 16. <IMAGE>

Title: Dispenser units
Inventor: DEAMER STANLEY JAMES
IPC: B05C17/01
Filed: 1984-01-05
Abstract: An electro-mechanical unit particularly but not exclusively for dispensing materials e.g. solder cream, glue or ink, which are difficult to dispense in small quantities due to constituent separation and subsequent dispenser blockage problems. Dispensing in discrete quantities is achieved by means of a solenoid- actuated push rod (1) which forces material from an output chamber (9) through an output orifice (2) when energising current is passed through the solenoid's coil (4). Air pressure is applied via a port (13) to maintain material in the output chamber (9) and prevent separation thereof, but the air pressure is chosen to be insufficient to cause exuding from the orifice (2). <IMAGE>

Title: Vascular graft
Inventor: POSSIS ZINON C
IPC: A61F2/06
Filed: 1986-02-03
Abstract: A vascular graft is used to supply blood to one or more coronary artery branches. The vascular graft has an elongated U-shaped tubular body providing a continuous passage for carrying blood from a high pressure blood supply to a blood receiver. One or more openings in the body allow blood to flow into the coronary artery branches. The flow and pressure of the blood in the passage is controlled by a restriction providing a Venturi passage located remote from the inlet end of the tubular body. The restriction is reinforced with an annular sleeve to maintain a desired cross sectional area and length of the Venturi passage. The pressure differential between the blood supply and blood receiver maintains continuous and adequate blood flow at a desired pressure in the body passage and provides a continual supply of blood for the coronary artery branches.
Patent GB-2177640-A (GB)
Title: Assembly of surface-mounted components
Inventor: GOLTEN DESIDER
IPC: H05K13/04
Filed: 1986-02-12
Abstract: A method of assembling a surface-mounted component (5) onto a substrate, such as a printed circuit board, comprising applying a deposit of solder cream to the substrate, preheating to boil off volatile material from the solder cream, and securing the component to the substrate prior to a reflow stage to solder the component to the substrate, in which adhesive is applied to the component (5) through cut-outs (7) by a device (9) prior to its location on the substrate by a transfer device (8). The application of the adhesive to the component, rather than to the board, cuts out a step in the processing of the substrate. The component is supplied as part of a stream of such components by a carrying medium (1, 2, 3) which has the cut-outs (7) beneath part of the component (5). The carrying medium may be a composite paper tape consisting of three layers (1, 2, 3), a flexible multiple blister pack consisting of two layers (1, 10) [Figure 8], each of which has multiple cut-outs (7), or a magazine having a single cut-out. When the components (5) are placed on the printed circuit board in their assigned position the adhesive achieves a secure mechanical bond between the board and the components thus preventing the components from moving, lifting or being blown off during the course of the reflow operation when components are fused by molten solder to the printed circuit board. <IMAGE>

Patent GB-2215071-A (GB)
Title: Thermo-optio deflector
Inventor: ZUBRZYCKI JOHN THOMAS
IPC: G02F1/29
Filed: 1988-02-02
Abstract: A deflector is formed from a block of glass (10), the refractive index of which changes with temperature with respective heating and cooling devices on opposite sides of the block. In practice two Peltier elements (20, 21) are attached to opposing surfaces of the block (10) and wired in series (22). When connected to an electrical source each element (20, 21) transfers heat (24) in one direction creating a linear temperature gradient (26) across the block (10). When the elements (20, 21) are not oonnected to an electrical source, an optical beam (12) may pass through the block (10) emerging undeflected (14). When current is applied, the emergent beam (16) will be deflected upwards due to the change in the refractive index of the glass. Reversal of the current polarity will change the direction of the temperature gradient (26) and the emergent beam (18) will be deflected downwards. The use of similar Peltier elements (20, 21) means that there is no net heat flow out of the deflector and, as such, the device is largely unaffected by changes in ambient temperature. <IMAGE>
